The smallest unit of computer memory is Bit. It can store either 1 or 0.
Measurements of computer storage/memory are:
8 Bits 1 Byte
1024 Bytes 1 Kilobyte (Kb)
1024 Kilobytes 1 Megabyte (MB)
1024 Megabytes 1 Gigabyte (GB)
1024 Gigabytes 1 Terabyte (TB)
, Storage Devices
Some storage devices are as follows:
