Introduction
There has been continuous quest for man to improve his well being through, reactions to problems and challenges posed by his environment. Over the years, computer and computer communication had gained so much attention and grown tremendously, reducing big and expensive mainframes into small and affordable devices. Statistics have shown that most people spend most of their time on computers, since most of their activities locally or globally over a network. Since much time is spent on computer system, it becomes necessary to design a device for controlling switches from computer. Switches are so essential that one can not avoid to use them on a daily basis for putting on or turning off electrical devices, and as a result of these, many devices have been designed by man to help him conquer these problems and challenges posed by physical contact with electricity. The switch control system can range from simply controlling of light without leaving a seat, to being able to switch on industrial electrical devices through a computer. There has to be an interface between industrial electrical devices and a controller, the PC in this case. Interface are required so that the PC can communicate with other devices (Osinuga and oresotu 2001), the interface used in this work is the computer port interface. The microprocessor switch control system is made up of several devices connected together; keypads that transmit commands to the device, fixtures controller that is programmed to on the appliances automatically via a computer system. [1]
MICROPROCESSOR- BASED SWITCH CONTROL SYSTEM:
Yong- Jing Nu (1998), observed that microprocessor based toggle switch control system is primary configured with a power factor corrector (PFC), a square- ware voltage generator, a manually controlled toggle switch and two relay. Toggle switch can select a different number of lamps in operation, resulting in a manual dimming feature.[2]
METHODOLOGY
Software Engineering has internationally accepted software Engineering standards for transforming ideals into an inference engine. They include:
v The structured system Analysis and Design methodology (SSADM)
v Prototyping
v Experts system methodology
v Usability Engineering methodologies, etc.
The methodology applied in the system is prototyping and is discussed below.
3.0 duction PROTOTYPING
In electronics, prototyping means building an actual circuit to a design to verity that it works, and to provide a physical plat forms for debugging it, it does not work. Prototyping sometimes converts intangible specifications into a tangible but limited working model of the desired information system. [3]
CLASSIFICATION OF SYSTEM PROTOTYPES
System prototypes could be classified into:
STEP INVOLVED IN PROTOTYPING
ADVANTAGES OF PROTOPING
DISADVANTAGES OF PROTOTYPING.
I. The process of developing a prototype can cause systems to be left unfinished or implemented before they are ready.
II. Prototyping can sometimes leads to incomplete documentation and insufficient analysis.
III. The process of developing a prototype may require greater involvement and commitment by key users who are already busy with their regular work.
IV. If sophisticated software prototypes are employed, the time saving benefit of prototyping can be lost.
V. In prototyping, structure of system can be damaged since many changes could be made and it is not suitable for large applications.
Our prototype in this project is constructed using a microprocessor to control electrical appliances.[5]
ANALYSIS OF THE EXISTING SYSTEM
The present procedure involves a manual control of the power switch by the industrial electrician. The power control switch is operated with hand by pushing the switch lever to on position if it’s intended to be turned on or off position if it’s intended to be turned off. Basically, during the analysis of this procedure, it is discovered that the operators is at high risk of been electrocuted. Manually, switches have been existing for many years in every home, industry, company, schools and colleges. [6]
These switches are in different standards such as:
This switch can be “ON” in both positions, switching on a separate device. In each case, it is often called a change over switch example; a SPOT switch can be used to switch ON red lamp in one position and a green lamp in another position.
REED SWITCH:
The contacts of a reed switch are closed by bringing a small magnet near the switch. They are used in security circuits, for example to check the doors and closed. Standard reed switches are SPST (simple ON/ OFF)
THREE FEATURES OF EXISTING SWITCH
Contacts (example single pole, double throw)
Rating (maximum voltage and current)
Methods of operation (toggle, slide, key etc.
THE PROBEM OF THE EXISTING SWITCHES (SYSTEM)
v Electrocution: Those switches claim a lot of lives as a result of direct contact of the operator with them for example; the operator might be electrocuted in the process of carrying out power change over.
v Time wastage: it takes time to go from one switch to the other to ON or OFF them whenever there is power failure.
v Friction: friction is applied in operating these switches. Worn out switches can lead to the damage of the electrical devices which it is controlling.
v Frequent touching of the switch causes the damage of the switch circuit.
v Bad switch control might result to serious inferno to industrial equipment and other valuables.
SWITCHING CIRCUIT
This circuit is made up of BC 337 transistor switching circuit; each circuit is connected to a relay, a transistor and diode. The relay when activated, ON or OFF any appliance connected to it. The three lives from the microprocessor are each connected respectively to the BASE pin of the three corresponding transistor.[6]
The circuit is the heart of this module. It comprises of 9-pin Dip-male connector, Max-232, 8051 microprocessor, crystal oscillator.
The circuit connects directly to the computer serial port through a pin cable. The MAX- 232 amplifies signal (VS) that goes into the microprocessor from the computer system through the serial cables. Serial data is transmitted from the PC as a series of positive and negative voltage on a single wire, which serial data occurred at a pre-determined time established by the base wire.
The 11-0597MHZ crystal oscillator determines the speed of the 8051 microprocessor used. The microprocessor is connected to the three BC B37A transistor that derives the three relays. Pin 2 an d3 of the serial port are connected to line 14 and 13 of the MAX- 232. [7,8]

USER’S GUIDE (MANUAL)
The user’s manual for the system will accompany the software CD. The aim of this manual is to guide the users on the appropriate steps to follow[9,10]
HARDWARE GUIDE
The switch controller must be connected to the system unit. The guide on how to connect it to the computer are:
v Insert the serial cable female port into “D- shape male 9- pins serial port at the back of system unit and screw.
v Connect the power cable into any power source of 240V
v Make sure the computer system cables are properly fixed.
TESTING:
Software or hardware testing is very important element of assurance and it represents the ultimate view of specification, design and coding. The main thing here is to execute a program with the intent to search for an error. If the program executes without any notable instate; there the objectives of conceiving it is achieved.
However, the free flow of the software was realized by removing bugs at early stages of the software development and the hardware was also realized by proper soldering of the components used on the breadboard
The New software and hardware project shall be tested thoroughly ensure that it meets the requirements in the specification. Macro et al stated that there are five stages of system testing or levels. These include;
v Function Testing: The functions and modules that make up the module are tested to ensure their correct operation.
v Module Testing: The functions are combined to form a module. This module is tested to ensure that its performance meets specifications. In this design the modules, which are tested and it responds positively which shows the modules are independently efficient and reliable.
v Integration Testing: This is some time called subsystem testing, a set of modules are integrated. As software module and hardware module interact, the testing focus is on modules interface because it is assumed that the modules themselves are correct. This test is carried out to ascertain that those modules do not loose their efficiency and reliability by integrating them into subsystems and systems.
v Total program testing: sometimes called system testing is the level where all the testing process concentrated more on detecting errors and determining how well user’s requirement are meet.
PROGRAM DOCUMENTATION (OPERATION)
Microprocessor- based main switch control system, is a system consisting of software and hardware module. The hardware module is the controller circuit, which must be connected to the system unit and the software module is in a CD-ROM and needed to be installed in the system unit (hard disk). This will only take effect when the controller is properly connected to the computer system through the serial port and to the power source. Any electrical device connected to it can be switch on or off through the interface provide by the software.
Depending on the previous by the software bulbs, when the command button of any relay is clicked, signals goes from there to desirable bulb.
When relay 1 is off the status will display “A” but when it is ON, the status will display “B” .
Also when relay 2 is off the status will display “C”, when it is ON the status will display “D”.
Finally when relay 3 is off the status will display “E” but the relay is ON the status will display “F”.
IMPLEMENTATION DETAILS
This detail involves the conversion of files, parallel or pilot implementation plans. This involves the change- over procedures. Once the system has been fully designed, tested for a good percentage of perfection and accepted, the change over plan can be made. So this plan is done using the two types below:
ü Parallel change over
ü Pilot change over.
PARALLEL CHANGE OVER:
This system will allow the new system to continue along side with the old system, for weeks or months. The disadvantage of parallel running is the extra effort required to keep both system running.
PILOT CHANGE OVER:
Here, the new system is introduced into one of the department or branches of an organization and run until it is proven to be satisfactory. Then if it works with little or no shortcomings, it can then the installed in all the organizations and department or implemented fully everywhere as the case may be.
For this project both change over plans will do, but we are implementing the pilot change over plan because this new system has so many advantages over the old system.
CONCLUSION
This work is recommended to be used in industries, large firms manufacturing industries e.t.c. This is to provides easy and safe use of the electrical devices; Instructions are programmed into the microprocessor to carry out their functions. The management of any organization using this project should employ computer analyst who will be operating this system.
The primary objectives of this project is to control electrical devices with computer through serial port was achieved successfully. The microprocessor in the control unit was programmed using assembly language.

Web hosting is where a company will have an online space where they will be able to save their website files and then make it visible on the internet. In this way, it will be possible for businesses to promote their products and services and increase the number of potential clients since the internet is now making it possible for people to interact with each other. And these days, there are already several types of web hosting services.
Linux hosting. This is one of the most popular web hosting services. From the makers of the Linux operating system, they are currently providing hosting services at a price that is very affordable for every client.
Windows hosting. This is also among the most popular website hosting services. Apart from just manufacturing operating systems, they have also been hosting websites for a number of years now and have been proven to be very reliable for website owners.
VPS hosting. VPS stands for virtual private server. On this type of web hosting service, a disk space is going to be partitioned so that other computers will seem to be running on its independent server in terms of capabilities and interface. Since they will have their own dedicated virtual servers, each can have their own operating system and even be booted up independently.
Reseller hosting. This is where a person is purchasing disk space and bandwidth then will be selling them to other companies. Since they are buying these server spaces in wholesale, they are getting them at a much cheaper price and gain more profit in the process.
Dedicated or managed hosting. This type of website hosting service is where a company purchases the whole server and makes it their own dedicated server. With this, they are going to keep their website secure since they are not going to share it with other companies.
So depending on the type of website that you are going to build, there is a server that will match it. The good thing about this is that you will find the ones that will fit your budget and your preference.
As long as you search the internet, you will find the companies that will give you the best web hosting service that will help your business boost up its promotion online. Just read reviews about the companies that offer website hosting to find the ones that will give you a reliable service.
A variety of web hosting options are available for every user’s need. Choosing the right website hosting can provide your website many benefits.

Millions of people have discovered the usefulness of a handheld GPS receiver. This is particularly true of outdoor enthusiasts whether they are hikers, backpackers, hunters, or geocachers because using the Global Positioning System tells them where they are in the world and how to get to where they want to go. If you are considering purchasing a handheld unit you may already have a good idea what they do but still have questions about which type of unit is best for you.
The first thing you need to know when purchasing a handheld GPS unit is what do you need it for. This is important because most GPS systems are designed for specific purposes. For instance a GPS receiver that is intended for use in a vehicle or boat will have features and data that may not work so well in the wilderness.
A handheld receiver is also smaller then a standard vehicle mounted unit and many can easily fit into your pocket. There is also a weight issue for those who are concerned with how much they are packing weighs. As the technology has progressed these small units have become not only more powerful but also have become much lighter then their predecessors.
Add-ons, accessories, and the ability to download software/data is also an important consideration. Again, this will depend on what you need a GPS for but these are things to consider. Firmware updates keep your GPS up-to-date and fix bugs that have been found in the operating software. Map and data downloads can make your unit more functional for your specific needs. Being able to interface with your home PC or laptop allows you to customize trip information and download/upload data.
The last thing to consider is ease of use and functionality. Are the controls/buttons easy to use? Is the display screen easy to see and read? Is there the option to customize displays with information that is important to your purposes? All questions that need to be addressed when choosing a handheld GPS receiver.
There is no better choice then a Magellan Portable GPS handheld unit when it comes to finding your way in the world. To learn more about Magellan GPS Systems please Click Here.

There are many online backup service providers today and their number is increasing everyday. Each new provider tries to differentiate their services by offering additional features with their innovative online backup system. Below is the list of the most useful features which can help you choose the one best for you:
Accessible anywhere: you should be able to access files protected by Online Backup systems at any time, directly from the client installed on your PC. Or you can access your files from any PC or cell phone with an internet connection via the service provider’s website.
Multicomputer (several computers, one account): only some services let a single user protect several computers with the same account. Most follow the concept: one account, one computer. Thanks to this system, you can Backup your home and office computers and access data through a single interface regardless of where the saved data came from.
Permanent storage: You should pay careful attention to storage length. In fact, some services guarantee protection for an amount of time that can be virtually infinite (as long as you pay the subscription). Others, on the other hand, only backup and protect data for several days (usually 30). This means that you only have 30 days to recover data that was backed up online. Otherwise data is permanently lost.
Real time backup: If a user creates a new file or changes an existent one, the client immediately and automatically saves new or changed files on the remote server. Not all services include this function. Some only backup files every 12 or 24 hours.
Fully automatic: Once you choose what to save, the client starts with the computer, silently and continuously running in background to protect data without having to intervene and only if computer resources (band, RAM, CPU) are not used by other more important processes. You can also decide to backup new files at any time until you fill all your available space.
Sharing: Online Backup is virtually an extension of popular “file sharing” systems – those services that let you publish your files online to share with friends or co-workers or provide you with a virtual HD on the internet. There is a significant difference with Online Backup. Data is already on the internet and is uploaded while you are working on something else. This data can be immediately shared with a single click. The size of the file to be shared doesn’t make a difference in some Online Backup services. The client automatically sends an e-mail to the file recipient with a link to the file. At this point, the person who receives the e-mail clicks on the link and simply downloads the file. Other systems have size limits for files to be uploaded and the process is more complicated.
Excellent performance: The best Online Backup services do not slow down your computer. Generally, they monitor how many resources are being used by the system and adjust to user needs. This way, they do not affect computer performance.
Search engines: The best Online Backup programs have an internal search engine that lets you quickly find and manage your files. Some have a semantic search system that lets you run advanced searches in documents with more detailed results.
Scalable On-Demand: Available space can be increased in almost all services by paying for additional Gigabytes. Many software houses sell standard packages of a set number of Gigabytes. Others are more flexible and take customer needs into account.
Versioning: the system traces all changes made on a certain file for a virtually indefinite period of time. Whenever the file is saved, the system only saves the incremental part, creating a new version. Thus, if you want to restore an old document that was accidentally overwritten, simply go back and open all the previous versions. The system does not delete saved files unless the user deletes them. Only a few providers include this essential feature.
Backup Data Offsite is an online provider of offsite data backup solutions and you can use the services of them to store data offsite.
Article Source: What to look for in an online backup service
There are many online storage providers to choose from out there. Therefore you will want to be precautious. Immediately you will notice that comparing data backup providers can be tricky. You will notice that your requirements may not be met by some of these online storage services. Do not be discouraged however; there will be an online storage provider that will meet your requirements. To decide on the best online storage provider, follow these 6 hints when you are comparing your online backup choices.
1. Use online storage reviews.
Online storage reviews are available for you to compare online storage services without you squandering your precious time, energy, and more importantly your money. Online storage reviews summarize and display all the significant features of every online storage service in such a way that is as easy to understand and compare online storage providers.
2. Compare data backup services on their interface.
The interface, typically an Internet-based control panel, is the instrument you will be working with in setting up, conducting, and retrieving online storage. Therefore it should better be something you are capable using quickly and easily. By checking online storage reviews or visiting the site for a demo (assuming one is available) of any of their interfaces you can acquaint yourself with the control panel that you might use if you select one online storage provider over another. Compare data backup interfaces mainly for how easy they are to use, not only to see how easy it is to learn and use, but also to see how the button layout accommodates you.
3. Compare data backup services on their online storage storage allotments.
Most online storage websites you check when you compare data backup providers offer different rates and plans for different amounts (normally measured in gigabytes) of information you require to back up. Several providers are capable or willing to offer unlimited online storage. While this seems useful it may or may not suit your needs. Unlimited online storage can be too much for some, particularly when there is a plan that is far more appropriate to their needs at a lower rate. However for some there no available ‘limited’ plans that can accommodate for their excessive online storage needs other than an unlimited backup plan. The smart thing to do here is to calculate your own online storage requirements before you compare data backup services (also calculate how much you will need in the future). Remember, there is no need to pay more for online storage than you have to.
4. Compare data backup services for the file types they support.
It can be imperative that any online storage service provider you consider supports all file types that you may want to have backed up. If you are backing up simple .DOC, .TXT, .RTF, .PDF files and other common documents, you will be covered by the majority of providers. However, if you need your online storage to accommodate unusual or more complex computer files, it is vital to make certain, that when you compare data backup services you only select a provider that has the capabilities to upload and store every file type you use.
5. Compare data backup services on their quality of customer support.
For sensitive online services like this – customer service is everything. It would be careless to join an online storage provider and spend your money just to lose your data. Therefore you must inquire into their quality of customer service. Does the provider have limited service hours? Can they offer support at any time or are business hours your only opportunity? Does time zone affect their availability if they only have business hours? Can you get help via the phone, email or online chat? Is there an online self-help section? Can you talk to a real person if you can talk to them over the phone? Is there a toll fee for phone support? Are responses through online chat or email automated or considered by real people? How long do you have to wait for a response? What will you have to do to get the online storage help you need? Each of these questions is important to ask when you compare data backup providers.
6. Look for a free trial or a money-back guarantee.
As a final point, you do not have to necessarily rely only on what you learn at online storage review sites to make your selection. At Online-Backup-Ratings.ca you will see that many online storage companies have various kinds of free trials of their services or offer a money-back guarantee for the first few months. This way you can experience their services yourself without losing any money.
Online-Backup-Ratings.ca offers helpful ratings of all today’s top online storage services. Learn how to compare data backup providers so you can save money, time and worries. Visit Online-Backup-Ratings.ca for great articles, resources and expert reviews!

Are you considering getting Apple’s new iPod Touch for your main portable media player? If so, you might want to reconsider. This year, Microsoft unveiled a brand new Zune, the Zune HD 32 GB, which is now highly contending for Apple’s number one spot with the iPod Touch. And it deserves it, too. With better graphics, sleeker design, user-friendly interface and better navigation, you might want to buy a Zune instead of buying an Apple iPod Touch.
1. Zune HD vs. Apple iPod Touch Screen Technology: The screen display on the Zune is way better than the iPod Touch. No doubt, Apple’s baby looks great, but Zune’s lustre, in addition to the easier navigability than Apple, makes it a great option for those wanting to watch movies in widescreen, browse the internet, and page through their photos.
2. Zune 4.0 Software vs. iTunes: Are you a fan of using iTunes software for absolutely every little change you want to make on your iPod? I certainly am not. I own a PC, not a Mac, and if you own an iPod, you know how much “fun” it is to make the two play together – they’re fighting all the time.
But with Zune, you get to use a PC-compatible software that’s for Zune, so you don’t have to worry about using processor-hog clunkers like iTunes when you want to update your media.
3. Zune navigation with Quickplay shortcuts: One awesome feature of the Zune HD that I’m really pumped about is the Quickplay feature. You can navigate to your recently downloaded, listened to, and favorite music and movies without having to scroll forever.
With the Apple iPod Touch, you have to scroll forever to find the songs you just downloaded or added, but with the Zune HD, this is remedied, and you no longer have to spend your life scrolling on and on.
You can learn more about the Zune HD at http://entertainmentelectronics.blogspot.com/2009/09/new-microsoft-zune-hd-better-features.html, which will also help you determine if you should buy a Zune or an iPod item for your personal needs and wants.

If you think Cisco training might be for you, but you’ve no practical experience with routers or network switches, you should first attempt a CCNA course. This will provide you with knowledge and skills to work with routers. The internet is made up of hundreds of thousands of routers, and large commercial ventures with several locations also utilise routers to keep their networks in touch.
Because routers join up networks, look for a program which teaches the basics (for example Network+, perhaps with A+) before you start a CCNA. You must have a basic grasp of networks before you start a Cisco course or you’ll probably struggle. When you’ve qualified and are on the job market, you’ll benefit from having a good knowledge of networks in addition to the CCNA.
The CCNA qualification is more than adequate; don’t be cajoled into attempting your CCNP. With experience, you’ll find out whether you need to train up to this level. If so, you’ll have the knowledge you need to master your CCNP – because it’s a difficult qualification to master – and shouldn’t be looked upon as otherwise.
A lot of training providers will only offer support to you inside of office hours (typically 9am-6pm) and sometimes a little earlier or later; not many go late into the evening (after 8-9pm) or cover weekends properly. Look for training with help available at any time of day or night (no matter if it’s in the middle of the night on a weekend!) Ensure you get access directly to professional tutors, and not a message system as this will slow you down – waiting for tutors to call you back during office hours.
Keep your eyes open for training schools that have multiple support offices active in different time-zones. All of them should be combined to offer a simple interface together with 24 hours-a-day access, when you want it, with no hassle. Don’t ever make the mistake of taking second best when it comes to your support. The vast majority of IT hopefuls that fall by the wayside, are in that situation because they didn’t get the support necessary for them.
Locating job security nowadays is problematic. Companies can throw us out of the workforce with very little notice – whenever it suits. Now, we only experience security in a swiftly rising market, driven forward by work-skills shortages. It’s this shortage that creates the correct setting for a higher level of market-security – a much more desirable situation.
The IT skills shortage throughout the country is standing at roughly 26 percent, as reported by the most recent e-Skills survey. To explain it in a different way, this means that Great Britain can only locate 3 certified professionals for each 4 positions that are available currently. This one concept in itself underpins why Great Britain needs so many more workers to get trained and become part of the IT sector. We can’t imagine if a better time or market circumstances is ever likely to exist for obtaining certification in this rapidly expanding and evolving market.
It’s likely that you’re quite practically minded – the ‘hands-on’ type. If you’re anything like us, the trial of reading reference books and manuals is something you’ll make yourself do if you have to, but you’d hate it. Check out video-based multimedia instruction if you’d really rather not use books. Learning psychology studies show that much more of what we learn in remembered when we use all our senses, and we take action to use what we’ve learned.
Programs are now found in disc format, so you can study at your own computer. Video streaming means you can watch instructors demonstrating how to do something, with some practice time to follow – in a virtual lab environment. Always insist on a demonstration of the study materials from your training provider. The package should contain slide-shows, instructor-led videos and fully interactive skills-lab’s.
Avoiding training that is delivered purely online is generally a good idea. Ideally, you should opt for CD and DVD ROM courseware where available, as you need to be able to use them whenever it’s convenient for you – ISP quality varies, so you don’t want to be totally reliant on a quality and continuous internet connection.
Get rid of the typical salesman who recommends a training program without performing a ‘fact-find’ so as to understand your abilities and experience level. Make sure they can draw from a generous stable of training programs from which they could solve your training issues. In some circumstances, the training start-point for someone experienced in some areas is often massively dissimilar to someone without. It’s wise to consider some basic user skills first. This can help whip your basic knowledge into shape and make the slope up to the higher-levels a a little easier.

The operating system of the computer has the registry at its core. Over time, the user will install and remove programs, always changing the registry contents. The registry can develop errors as it collects redundant and outdated files over time and it is necessary to fix them. If left alone, the computer can break down or freeze up and the performance can become noticeably deteriorated. The famous blue screen of death may show itself. All this can happen in even new computers with redundant programs. What is needed is a cleaner for registry errors.
If there are suspected problems with a registry, they are best dealt with quickly. The registry is vital for the successful operation of the operating system such as Windows. It is needed for running all applications and programs. If not dealt with right away, the computer may completely collapse.
There are some common signs, which indicate a problem with the registry. Firstly, it may be that applications take ages to open or the computer is crashing all the time. Alternatively, the system may be running very slow or has problems whereby it freezes. There may be unexpected error messages or even the dreaded blue screen.

In today’s article, I’m going to quickly inform you about the Cisco IOS RITE configuration command named “bidirectional”.
Network administrators (like you) use the “bidirectional” command to enable (allow) incoming and outgoing IP traffic to be exported across a monitored interface.
In other words, by default a monitored interface only exports incoming IP traffic; but if you (a ccna) need to export outgoing IP traffic as well, you can use the bidirectional command to do so.
Below is the command’s syntax:
bidirectional
As you can see, the command is very easy to use it doesn’t use any keywords or arguments.
And, if you need to return a monitored interface back to its default behavior after configuring it with the command; all you have to do is type the word “no” in front of it like you see below:
Router(config-rite)#no bidirectional
Below is an example of the command being used:
Router>enable
Router#configure terminal
Router(config)#ip traffic-export profile charlesross
Router(config-rite)#interface FastEthernet1/0.1
Router(config-rite)#bidirectional
Router(config-rite)#incoming access-list 101
Router(config-rite)#outgoing access-list 101
Router(config-rite)#mac-address 7777.7777.3333
Router(config-rite)#end
Router#copy run start
In the example of above, the FastEthernet interface is being configured to export both incoming and outgoing IP traffic. Notice that the command is being performed in (RITE) configuration mode.
By the way, if you decide to use the command, make sure your router(s) is running Cisco IOS 12.3(4)T or higher.
I hope this article was very informative and helped you quickly understand the usage of the bidirectional command. If you need to learn more; I suggest you visit my website, were you’ll find the latest information regarding the Cisco CCNA (640-553) Security exam techniques.

It’s been a few days now since YouTube Remixer was launched and I’m sure you already had a taste of it. At first glance it seems like a good idea to add a video editor to a video sharing site. It even has some interesting functions. I’m not saying it’s bad, but the interface is dull and gray, all left-aligned and somewhat uninspiring. If you get over that, the functions provided are interesting for the casual YouTube uploader. As a downside there aren’t enough presets you can use. If you’re a regular user and you choose to edit your movies using the Remixer, that means you can’t use professional, more complicated applications to create evolved visual effects.
On the other hand it was about time to implement an application like this, Photobucket for example has a Remix tool for a while now. Both editing tools are powered by Adobe Premiere Express Technology, and it accepts all sort of audio, graphic and text overlays, transitions, etc.
So the YouTube Remixer will probably keep users a little longer on the website, but I really hope it will get nicer when it gets out of the Beta phase.
