USB is the acronym of Universal Serial Bus (Universal Serial Bus , in Spanish). It is a concept of the computing to name the port which enables connect peripherals to one computer .
The creation of USB It dates back to 1996 , when a group of seven companies (among which were IBM , Intel and Microsoft ) developed the format to improve the interconnection capacity of technological devices. He USB , unlike other ports, does not require the restart of the system to recognize the connection of peripherals (it has a greater capacity plug-and-play or connect-and-use).
He USB is able to detect and install the software necessary for the operation of the devices. Unlike other types of ports (such as PCI ), does not have a large bandwidth for data transfer, which is a disadvantage in certain cases.
He keyboard , the mouse or mouse , digital cameras, scanners, printers and mobile phones are some of the peripherals that can be connected to a computer through the port USB .
All this without forgetting other equally important peripherals such as video cameras, external DVD recorders, portable hard drives, pendrives, musical devices such as MP3's, joysticks, steering wheels or the webcams.
There are currently four types of ports USB which differ according to their data transfer speed. He USB 1.0 It has a maximum transfer rate of 1.5 Mbps and is used on devices such as the mouse and keyboard. He USB 1.1 it can reach a transfer rate of up to 12 Mbps, while the USB 2.0 reaches up to 480 Mbps. The USB 3.0 Finally, it is in the development stage and could reach a transfer rate of 4.8 Gbps.
USB 3.0 can determine that it is not only ten times faster than its predecessor but also significantly reduces energy consumption. And all this without forgetting that, in the same way, it decreases the time it takes to be able to carry out the corresponding data transmission. Reasons all of them that have made that right now he has become the most requested.
However, we cannot ignore the existence of what is known as USB memory. This is a small device that is used to store a large amount of information through what is known as the Flash system. It also receives the name of pen, pendriver, memory stick or memory key, among others.
At present, the USB memory has become one of the most used computing devices by citizens around the world. And it allows you to carry a large amount of information with you in a small device of small dimensions, of low weight and, therefore, easily transportable.
Up to 1 TB of data can keep a pendriver that connects via a USB connector to a mobile phone, tablet or laptop, for example.
