Nibble

A nibble is a unit of memory made up of 4 bits.

This means it can store 16 possible binary values, 0000 to 1111.

Byte

A byte is a unit memory made up of 8 bites. This means it can store 256 binary values, 00000000 to 11111111.

Units

8 bits 1 byte

1024 bytes 1 kilobyte (1000)

1024 kilobytes 1 megabyte

(million)

1024 megabyte 1 gigabyte (billion)

1024 gigabytes 1 terabyte (trillion)

Why hexadecimal

Binary patterns are very inconvenient for humans to read.

-therefore,binary numbers are commonly put into groups of four buts and displayed using the hexadecimal number system.

hexadecimal numbers take up considerably less space than binary numbers. because of this they are often used to represent 8-bit binary numbers in computing.

Rules

convert the denary number to binary.

divide the bits into groups of four, starting from the right.

convert each group of four digits into hexadecimal.
