Units of Memory :
Memory, storage, files and folder sizes are all measured in bytes. Computers work in the base 2 system, also called binary number system, using only the digits 0 and 1. A single numeric value using either 0 or 1 is called a bit. A sequence of ‘bits’ make a byte. Usually eight bits make a byte (sometimes it could be sixteen, thirty two or even sixty four). Bits are grouped into bytes to increase the efficiency of the computer. To describe large capacities, the terms Kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB) and Petabyte (PB) are used.
1 nibble = 4 bits
1 KB = 1024 bytes
1 GB = 1024 MB
1 PB = 1024 TB
1 byte = 8 bits
1 MB = 1024 KB
1 TB = 1024 G
