Please Fast!!! I Need To Do My Homework. Thanks!

Answer 1

Answer:

1 Byte = 8 bits. 1 KiloByte = 1024 bytes. 1 MegaByte = 1024 kB. 1 gigaByte = 1024 mb. 1 teraByte = 1024 gb.

Answer 2

Explanation:

bit is a binary digit, the smallest part of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively.

Because bits are so small, you rarely work with information one bit at a time. Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h".

A kilobyte (KB) is 1,024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system.

Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB). 1 MB is 1,024 kilobytes, or 1,048,576 (1024x1024) bytes, not one million bytes.

Similarly, one 1 GB is 1,024 MB, or 1,073,741,824 (1024x1024x1024) bytes.

A terabyte (TB) is 1,024 GB.

A petabyte (PB) is 1,024 TB.

An exabyte (EB) is 1,024 PB.

A zettabyte (ZB) is 1,024 EB.

a yottabyte (YB) is 1,024 ZB.

Hopefully you are satisfied with my answer, pls mark me as the brainliest.
