In the modern world of today we use a lot of USB connectors. We use them to connect our video game systems, charge our mobile phones and digital cameras, well, almost every other electronic device that you can think of. The fact is that we use them all the time, but do we really know what they are? You probably do not know. USB is something that we hold in our hands all the time, but we never really knew that we were ignorant about until recently. That’s why we take for granted USB connectors, basically. So today we decided to expand your mind and tell you what those little nifty features are, what they do, and how they are used.
usbcableUSB stands for Universal Serial Bus. It is an industry standard that was developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication and power supply between computers and electronic devices. Simply put, this device was created so that was standardised connection of computer peripherals. Computer Peripherals include items such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network cards. The USB has done its job to make things easier for us, the consumer, and for the production of computer companies and industry experts.

The Universal Serial Bus has done two jobs at a time. In the first place, it communicates signals and information between the two devices. Consider, for example, a keyboard. The USB keyboard that connects to your computer to turn communicates the letters you want to display on the screen and the keyboard shortcuts that you use, among other things. USB also sends photos from your digital camera to the computer tower so that the computer can transmit the tower to the screen. All this is transferred and communicated through the USB port.

The second use of the USB connectors is transmitted and provides electricity to digital devices. This works in the same way of a traditional plug and outlet. The difference is that a USB port for the transfer of electrical energy from an object to another. For anyone using an electronic tablet, an example is when you use the USB drive to load. The USB transfer electricity from your computer to your tablet. Some digital cameras or mobile devices can be charged by hanging them to your computer via USB.

USB Size Variations: The universal serial bus is available in three different sizes. These dimensions are known as the plug, plug-B, and Micro-USB.

Plug-In is 12 mm wide and 4.5 mm high. It consists of four pins in a row, alternating positive and negative signals.

The connection B is 8.45 mm in width and 7.78 mm in height. It consists of four pins, two pins in the upper and two lower pins. The positive and negative signals alternate up and down, and side to side.

Micro-USB connectors (also known as the Mini-USB) are only 7 mm in width and 1.5 to 3 mm in height. It is a miniature version of the plug or plug B.
