Any number can be represented by a sequence of bits, using a positional notation in base two similar to our usual notation in base 10. With numbers we can encode any other data. This requires eight bits. An eight bit unit is called a byte . Computer Memory Programs and data are stored in computer memory.
Computer memory is a sequence of bytes.
Each byte has an address . A byte or sequence of bytes in memory is called a memory location or just a location . Each location can be identified by its address and length. The contents of a memory location is sometimes called a value or an object . The contents of one address can be another address.
