About The Universal Serial Bus (USB)

USB is a plug & play interface between the PC and certain devices such as keyboards, mice, printers, modems, sound cards, digital cameras, etc., which in the past were connected in different ways such as through serial port or parallel, which require different drivers to function and were much slower than the transfer rate is refiere.Esta interface is also used in data storage devices such as USB memory or the safety device that our PC is locked and can not access our information such as USB keys

We can name several benefits from the USB port: 1 - One of the most important features is that it allows devices to work at speeds on average about 12 Mbps, which is about 3 to 5 times faster than a port device parallel and 25 to 40 times faster than a serial port device.

2 - It has a simple connection, since it only has one type of cable, so no errors will be logged tantoprácticamente when installing the printer, camera or even a storage device such as a flash drive, since there is only one type of cable (USA AB) with different connectors at each end, so it is impossible to connect incorrectly.

3 - It is multiplatform, you can use both on different operating systems like Windows, Linux or OS2 and different hardware platforms such as PC or MAC. It thrives to compatibility, since it eliminates the risks when offering a range of products, enabling manufacturers to create innovative combinations of PCs, peripherals and software that meet the needs of specific market segments. To recall that in the past, each device had a different port, parallel port printer, mouse, serial port, as well as the keyboard uses a port other than named ps / 2.

4 - It is Plug and Play, that is when we connect a printer or scanner through the USB interface, no need to shut the computer for new hardware is detected and the system automatically recognizes the connected device and installs the appropriate drivers , which allows it to be hot-pluggable, meaning that the user can connect and disconnect USB devices whenever you want without having to power cycle the machine.

5 - It is of great benefit to people with less experience in the computing world as to connect certain devices such as a network card or modem, years ago if they had to resort to opening or installing the CPU the device, this is much easier and simpler because now these devices are connected externally via USB.

6 - USB technology allows connections in place, so that users can easily incorporate a printer and when needed, USB, you can connect up to 127 devices to our computers. The picture shows a device for connection to expand the number of devices.
