subject: Usb Cables - From Pins To Ports [print this page] When a connection between several devices and a host controller, which is usually a personal computer, is needed it is most commonly established with USB. USB, Universal Serial Bus, was invented to replace serial and parallel ports. However, this cable has exceeded its intentional purpose. USB cables have taken the place of aged connectors once used. In the past when a printer or mouse needed to be connected to a computer a search would take place behind the motherboard for the correct symbol and place to plug the cord into. Now, all one must do is simply locate the long row of USB ports behind or in front of the tower and plug the cable to it and go.
The useful aspect of a USB cable is that through device communication free range through all devices connected can occur. Of course, each peripheral needs permission from the user to connect to the host so that data can be successfully transferred. With a long list of what can be connected to a host through the use of USB, video game consoles, external hard drives and smart phones and be used to the far extent of their abilities. At the potential of use is endless!
An appealing feature regarding USB cables is the feeling one receives when it is plugged in correctly. Because of the amazing design, it is difficult to attach the connector upside down. When the socket and plug have joined together in the right manner, they are not easily separated except for with pulling it straight out from the device. In a humorous sense, watching someone fumble around with their arms reaching behind the computer tower trying to first of all locate the position of the hole and then make sure the connector is right side up without seeing the installation can be very difficult. Generally a person will also have to try inserting the cable both ways. Yet through all of the pull and tugging these cables receive they hold up to the tests of time and outlast many other cable options.
The ends of USB Cables are intentionally created another way. When looking at the ends of cables it is noticeable that one end is a type A receptacle which is the universal USB plug and the other end has a type B connector. Type B connectors are produced by various vendors and are exclusive to the device. You can buy long a USB cable though Data delay can be avoided by purchasing cables at the shortest length possible.
