IT: Programs & Hardwares -> Peripherals & Bios

 

Peripherals:

    Let's talk about USB that stands for Universal Serial Bus.

• USB 2.0: Transfer speed of 480 mbs/s
• USB 3.0: Transfer speed of 5 Gb/s
• USB 3.1: Transfer speed of 10 Gb/s 

    In general, USB 2.0 are black ports, USB 3.0 are blue ports, & USB 3.1 are teal ports.

PAY ATTENTION

    MB is megabyte ( unit of data storage) don't confuse it with Mb/s that is megabit per second, which is a unit of data transfer rate.

    1 byte is 8 bits, so to transfer 1 MB in a second you need 8 Mb/s connection speed!

Bios:

    Installed in ROM chip, & it's how CPU talks to other components.

    Today's systems uses another bios player called: UEFI that stands for Unified Extensible Firmware Interface.
