17. Types of USB Standards
To put it simply, the different versions of USB cables, like USB 2.0 and USB 3.0, are
concerned with the functionality and speed of the USB cable; whereas, the type of USB cable
(like USB Type A, USB Type B) essentially refers to the physical design of the plugs and ports.
19. USB Type A and USB Type B
The slot where one end of the USB cable is attached to the computer (the host) at the
back or front of the CPU cabinet is called the port. The electronic device that you wish to charge
or transfer data to (say, your smartphone or tablet) is called the receptor.
20. USB Type A and USB Type B
The most popular type of USB standard is Type A, which you can see at one
end (the end that goes inside the slot of the host) of almost every USB cable
nowadays. You will most likely to find Type-A ports in host devices like desktop
computers, gaming consoles and media players.
21. USB Type A and USB Type B
Type-B connectors are at the other end of a typical USB cable that plugs
into a peripheral device, such as a smartphone, a printer or a hard drive.
22. What is USB Type-C (or USB-C)?
USB Type-C (referred to as Type-C, hereafter) made the headlines of
tech periodicals around the world when the latest variant of Apple’s 12-
inch MacBook was launched. It is the first notebook to incorporate
Type-C in its design.
