The Facts Of USB And USB Cables

By Gloria Pryce


The Universal Serial Bus (USB) has been around for a number of years, and its creation has solved the problem of a lack of or incompatible connections available to link computer peripherals to a computer. Before USB was available, most devices were required to connect to a computer by using parallel and serial ports. These two ports have been around for 2 decades, serving effectively in linking computer peripherals to a computer. Unfortunately there was a problem: a standard computer has only 1 or 2 serial ports and one parallel port. This severely limited the number of computer peripherals that could be attached to a single computer. Thus, if a user wanted to connect a joystick, printer, and scanner, they might require the use of every port installed on their computer. Since these ports also require the computer to be powered off before any connections can be made or broken, switching peripherals was inconvenient. Even more problematic was that the data transmission rate between these devices and the computer was prohibitively slow for any but the oldest devices.

Different genres of games are starting to pop up such as online strategy and role-playing games. But do you still remember the good old arcade games? That Pac-man eating yellow dots and Mario and Luigi consuming mushrooms and flowers to rescue the princess from King Koopa? These games are considered to be the ancestors of the games that you play today on your computer or videogame station.

Old arcade games started after World War II, after Ralph Bauer invented the perception of creating an electronic game system to the television screen during the early 1950's. When he presented his ideas to Magnavox, a television company during that time, it was approved and resulted in the release of a refined version of Bauer's Brown Box prototype, which is known as the Magnavox Odyssey in 1972.

It displays only spots of light on the computer screen and it requires the use of translucent plastic overlays to reproduce the appearance of the game. In other words, this gaming version is prehistoric compared to present gaming standards.

The first gaming console system that was invented is known as the Atari 2600, which was released in 1977. It used plug-in cartridges in order to play different games. After the release of Atari 2600, old arcade games started their Golden Age in the gaming industry. This is considered to be the era when the popularity of such games increased drastically. It began in the late 1979 when the first colored arcade game appeared.
