A bit is a single 1 or 0 used to store digital information. 8 bits make up 1 byte, which can store a single character. Storage sizes are measured in bytes, kilobytes (1024 bytes), megabytes (1024 kilobytes), gigabytes (1024 megabytes), and terabytes (1024 gigabytes), with each increasing unit being 1024 times larger than the previous one.

1. Units of Storage

2. Bits and Bytes
 A single 1 or 0 is called a bit.
 8 bits = 1 byte.
 1 byte is used to store a single character.

3. Bytes, Kb, Mb, Gb and Terabytes
 8 bits = 1 Byte
 1024 Bytes = 1 Kilobytes (Kb)
 1024 Kb = 1 Megabytes (Mb)
 1024 Mb = 1 Gigabytes (Gb)
 1024 Gb = 1 Terabytes (Tb)
