These days a lot of USB connectors are used. We use them to plug in our video game systems, to charge our mobile phones and digital cameras, and so almost all other electronic devices that you can imagine. The point is that we use them all the time, but do you really know what they are? Probably they are not. The USB is something we have in our hands all the time, but never really knew they were ignorant until now. This is because we take for granted USB connectors, usually. So today, we will expand your mind and explain what these nifty little devices are, what they do, and the different ways they are used.
- What are they? USB stands for Universal Serial Bus. This is an industry standard that was developed during the mid-1990s that defines the cables, connectors and communication protocols used in a bus connection, communication and power supply between computers and electronic devices. In short, this device was created for the connection of computer peripherals standardised. Computer peripherals include elements such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters. The USB did his job in simplifying things for us consumers and for companies manufacturing equipment and industry specialists.
- What they do? The Universal Serial Bus does two jobs at once. First, signals and information between two devices communicate. Take, for example, a keyboard. The USB keyboard to a computer tower connects the letters you want to appear on the screen as well as keyboard shortcuts using, among other things it communicates. A USB also transmits images from the digital camera to the computer tower so that the computer tower can transmit back to the monitor. All this is transferred and communicated via USB.
The second work of the USB connectors are for transmitting and supplying electrical power to digital devices. This works in much the same way as a traditional plug and socket outlet. The difference is that a USB can transfer electricity from one object to another. For anyone who uses an electronic tablet, an example is when the USB is used to charge them. The USB is the transfer of power from the computer to the tablet.
- What are the size variations? The Universal Serial Bus comes in three different sizes. These sizes are known as the plug, B-plug, and Micro-USB.
The A-plug is 12 mm wide and 4.5 mm high. It consists of four pins in a row, alternating positive and negative signals.
The B-plug is 8.45 mm 7.78 mm wide and high. It consists of four pins, two pins on the top and two pins on the bottom. Positive and negative signals alternate top and bottom, and side to side.
Micro-USB connectors (also known as the Mini-USB) are only 7 mm wide and 1.5 to 3 mm high. It is a miniature version of the plug A or B plug.
We hope you have illuminated some of the complexities of the universal serial bus. For such a small device, which is a truly complex system that we have come to take for granted, but it really should not. Today, take a look at all the things you do with your USBs and really see how important it has become in modern times.
