BINARY MEMORY
MEMORY – Memory is a data storage device in a computer system. The data is stored in binary form (0 to 1)
The computer data is made up of certain components basically called bits and bytes.
BIT – It is the most basic information unit used in computing and formation theory.
A single bit is 1 or 0, a true or false or a ‘flag’ which is on or off (use to distinguish two mutually exclusive states from each other)
NIBBLE – A nibble is the computing term for the aggregation of four bits or half an octet (an octet being an 8-bit byte)
A Nibble contains four bits.
BYTE – A byte is a collection of 8 bits. Eight-bit bytes also known as Octets, which can represent 256 values.
MEMORY MEASUREMENT-
Memory or any storage device’s capacity is expressed as a quantity of bits or bytes.
The units of memory measurements are discussed below:
Kilobyte – A kilobyte is unit information or computer storage equal to 1024 bytes. It is commonly abbreviated as KB.
Megabyte – A megabyte is unit of information or computer storage equal to 1024 kilobytes. It is commonly abbreviated as MB.
Gigabyte – A gigabyte is unit of information or computer storage equal to 1024 megabytes. It is commonly abbreviated as GB.
Terabyte – A terabyte is unit of information or computer storage equal to 1024 gigabytes. It is commonly abbreviated as TB.
Petabyte – A Petabyte is unit of information or computer storage equal to 1024 Terabytes. It is commonly abbreviated as PB.
Exabyte – An Exabyte is unit of information or computer storage equal to 1024 Petabytes. It is commonly abbreviated as EB.
Zettabyte – A Zettabyte is unit of information or computer storage equal to 1024 Exabytes. It is commonly abbreviated as ZB.
Yottabyte – A Yottabyte is unit of information or computer storage equal to 1024 Zettabytes. It is commonly abbreviated as YB.
