Here are some important things related to computer.


→ Memory storage capacity is measured in bytes.


Units of data measurement:

Bit/Binary digit = 0 (or) 1
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
1024 exabytes = 1 zettabyte (ZB)
1024 zettabytes = 1 yottabyte (YB)
