IMPORTANCE AND USES OF USB TECHNOLOGY: Before the end of the twentieth century, in the world of computing and telecommunications, different types of connections were still used to connect peripherals, accessories and mobile devices: PS2, for keyboards and mice; serial port, also for mice, game controls and mobile devices; and the parallel port, reserved for printers and you can buy these gadgets from the gadgets trend.
By taking a look at the back of the computers, you could see a good variety of available ports, of different sizes and formats each one. But from 1994, seven leading companies in the computer world, including Intel and Microsoft, began to work in a standard port for the entire market: in 1998 one of the first versions of USB would be massively introduced (Universal Serial Bus).
The introduction and adoption of a market standard, in the connections of peripherals and accessories to computers, contributed positively in the exchange of files and information: wealth, communication, data type and speed in the rate of transfer have been key points in the development of USB technology.
The USB has evolved and improved its capabilities over the years, especially in the rate of data transfer, to adapt to the requirements of interconnected products: if version 1.1 of USB had a transfer rate of 12 Mbit /s, the 2.0 increased to 480 Mbit / s and the 3.0 to 5 Gbit / s.
The USB connection is the best-known solution, by cable, to exchange files between a computer and a mobile phone, music player, video camera, tablet, USB memory or external hard drive: copy and extract files quickly and easily, without delays or failures in the recognition of connected devices. Thanks to the USB port, it is very fast to copy heavy files such as DivX movies of 2GB, mp3 music albums of more than 120MB or multiple high-resolution photographs of more than 10MB each. With the increase in the transfer rate, mobile hard drives with capacities of over 500GB have been consolidated as an optimal solution for backing up gigabytes of data in a few minutes, and as a frequent activity to keep large files safe.
IMPORTANCE FOR THE USER OF PCS
With the introduction of USB technology an easy recognition and installation of new devices connected to a computer were brought: the slogan “Plug & Play” was defined. It would not be necessary for computer owners to have a great knowledge of computers to enjoy and start using a new device, performing an automatic configuration with hardly any user intervention.
The USB cable is the one that accompanies any current modern device, with one end adapted to the type of product that uses it: most computers use a micro-USB connection, although some still integrate a mini-USB connection, something larger. The advantage of the connection standard, in the case of micro-USB, is that it is no longer necessary to carry several types of cables when traveling, but only one can be used to take advantage of different types of devices: one for the camera photographs, mobile phone, Bluetooth headset and music player (not Apple).
The USB port of computers fulfills three basic functions: the exchange of files, the communication between products and the loading of mobile devices. Through the various ports of 5V – 500mA of a computer, it is possible to charge mobile phones, wireless headphones, music players, external batteries and even tablets: a great advantage when there is no availability of a wall socket or not It has a charger for the device. Through special adapters to standard USB, it is also possible to charge a device while traveling by car, using the cigarette lighter connection.
USB has not only been a key technological development for the world of information technology but has also spread to the world of telecommunications and consumer electronics. One of the clearest examples is mobile phone chargers, with USB port and 5V power, which can be exchanged with multiple devices. The other example is in the USB ports digital media players (music, video, and photography) of televisions, Blu-ray players, home theater, compact audio equipment and radios. Thanks to the development of the “universal serial bus” you can enjoy DivX movies and mp3 music downloaded from the Internet, and played on audio and video equipment at home.
Universal Serial Bus (USB) has great importance in the computer world, contributing to an improvement of the communication with the diversity of electronic products. The impact of USB has taken place both at the level of private use and at the level of business use.
