Author: The name Sony was created by combining “SONUS,” the original Latin for “SONIC,” meaning sound, with “SONNY,” denoting small size, or a youthful boy. It was chosen for its simple pronunciation that is the same in any language. So why is Sony one of the greatest consumer electronic manufacturers?
Since 1946 Sony has been committed to bringing the world the best in technology. Even though Sony has been around for many years, the original Sony was actually called – Tokyo Telecommunications Engineering Corporation or more commonly Totsuko. It was only in January 1958 that the company changed its name to Sony Corporation after taking “SONUS,” the original Latin for “SONIC,” meaning sound, with “SONNY,” denoting small size, or a youthful boy. So, the name Sony was used because of its ease of pronunciation in any language!
Apart from looking at simply the corporate world of Sony, there is much more to Sony that makes it a leader in consumer electronics. This innovation comes with Sony not just simply recreating products, but actually inventing new technology.
In May 1960 – Sony was the first company to create the world’s first direct-view portable TV. The TV8-301 the world’s first non-projection-type portable transistor TV set comprised of 23 transistors and 19 diodes, this model was developed based on Sony’s extensive experience in radio technology. In an age when TV sets were assumed to be living room fixtures, this device opened the door to personal television use. Additionally, the TV8-301 model offered three choices for power input.
Sony didn’t stop there, in fact Sony actually moved ahead and innovated more and more. In 1967 they invented the world’s first IC radio, and in 1968 Sony brought us the marvelous Sony television Trinitron technology by releasing the KV-1310 to the masses. Sony has been leap years ahead with its technology in TV sets. And the Trinitron technology has filtered through the years, getting better and better to ‘WEGA’. Sony now brings us the Bravia range of high definition TV sets. In fact the Sony television Trinitron technology was such a major breakthrough in TV technology that in May 1973, Sony became the first Japanese company to receive an Emmy for developing the Sony television Trinitron technology color TV system.
There are so many new products that Sony has brought us, which we did not have before. The Walkman is probably on of the greatest inventions from Sony. Before Sony invented the portable Walkman, there was no practical way of going for a Jog with music playing. Sony also brought us the world’s first compact disc player also, which is something we see included in our PC, our HiFi system, and our car!
The Sony Playstation is another breakthrough. The Sony Playstation range has gone from 1 to PS2 to now PS3 and it looks like Sony will continue to make breakthroughs in the console market. The Sony Playstation is not quite a PC, but its specs make it pretty close.
Sony is one which has left its mark on history as one of the only consumer electronic companies that has brought to the world so many world firsts. Sony even has AIBO, a robot dog that is just as good as a dog, without the problems.

Dynamic ram simply required an only transistor plus a solitary capacitor for every small piece, so it might be a set denser – stuffing in the region of three periods as frequent bit for each four-sided figure millimeter as motionless ram. Sooner or later, DDR evolve toward DDR2 – then conflict broke away fought on top of two huge battlefields. They are ahead the field of Latency of Bandwidth. Since processes were enhanced, DDR2 was capable to get to superior height within the each and every one forceful Megahertz position. DDR2-667’s be capable to grip their own beside DDR-four hundred. DDR2-800 will get the show the way and after that DDR2 small latency reminiscences ongoing to come into view. Random Access Memory (RAM) is that part of the pc which stores data that the computer needs while it is working. It is the RAM because of which the pc can get the information in any sequence, not compulsory in the manner in which it has been stored. It is approval fact, the more RAM the better the speed of operations. DDR2 offers quicker access rates and is swiftly becoming the standard for pc memory. RAM is a non-volatile memory that is as soon as the power is switched off all the data is lost, so this is where hard disk steps in.DDR2 Memory tools that endeavor to offer computers with elevated bandwidth memory. When DDR2 frequencies went up and about, so do the voltages essential the stage at the upper information rates – and of way this basis ever additional temperature to be generate. To purchase a RAM you have to check whether it is compatible with your Motherboard in terms of slot type plus the data bus speed. All your computer programs will run faster, better and smoother. You will save a lot of time. An interesting feature of a motherboard is that it supports DDR2 memory.RAM is essential for several different applications. There are several options to choose from when upgrading RAM. The first is the size of RAM you want to purchase. They come in 256mb, 512mb, and 1gig and 2gig varieties. Once you pick the size of the RAM you want you have to choose the type of RAM. There are two main types of RAM.DDR and DDR2. What you have to take into account when buying the RAM is which type your motherboard will support. Most new Intel motherboards will take DDR2 as this is the latest technology.
