Different Types of USB Connectors

It is important to know about the various USB connector types because this is the port through which all peripheral and external devices are connected to a computer. Whether it is a desktop computer, a laptop computer, a notebook or even a tablet PC (newer models), it is necessary to have a few USB ports on the device so that external devices can be easily connected and charged.

USB stands for Universal Serial Bus, and it is a standard form of communication between two electronic devices where one device (usually the computer) takes up the role of a host. Any kind of peripheral device or computer hardware that connects with a computer does so through a USB port today, and it is standard practice to have at least 2 such ports on every machine now.

Different Types of USB Connectors

All USB cables have two plugs on either end, and one of these sides goes into the USB port that is on the computer. These are known as type A USB male plugs, and they are the rectangular connectors that fit into the port on the machine. Every peripheral has one side of the cable attached with this connector since this is the only way to connect to the computer. Some devices which use this connector are the computer mouse, computer keyboard, USB flash drives, external hard drives and video game consoles.

Then you have the type B USB connectors, that are more squarish in shape, and are also slightly tilted at the top. The most common peripherals that are attached to this connector are printers and scanners for the computer.

After this you have the microUSB type A and type B which are smaller variants of the two above mentioned USB connector types. A micro USB connector is used for connecting a variety of devices like digital cameras, PDA's, old and new mobile phones and smart phones, MP3 players and handheld GPS units.

You may have also heard about mini USB connectors. These are also known as USB mini-B connectors, and they come either with 4-pin connectors or 5-pin connectors. These USB cable types are not that common anymore, but they do come with certain models of digital cameras even today.
