Storage Units in Computer Science
Memory capacity is denoted by bits and bytes and multiples thereof
1) Bit : within the binary number system, each 0 or 1 is named a small amount, which is brief variety of "binary digit".
2) Nibble : Half a byte (four bits) is named nibble.
3) Byte : To represent letters, numbers, or special characters (such as * or ?), bits are combined into groups. a bunch of 8 bits is termed a byte, and a byte represents one character, digit or other value. The capacity of a computer's memory is expressed in number of bytes or multiples like kilobytes and megabytes.
4) KiloByte : A Kilo Byte (KB) is about 1,024 bytes. The Kilo Byte was a typical unit of measure for memory or memory device capacity on older computers. 1 KB equals about one- page of text.
5) Mega Byte : A Mega Byte (MB) is about 1 million bytes (1,048,576 bytes).Measures of microcomputer primary-storage capacity nowadays are measured in Mega Bytes. 1 MB equals about 500 pages of text.
6) Giga Byte : A Giga Byte (GB) is about 1 billion bytes (1073,741,824 bytes). This measure was earlier used mainly with mainframe computers, but is typical of the memory device (hard disk) capacity of today's microcomputers. 1 GB equals about 500,000 pages of text.
7) Tera Byte : A Tera Byte (TB) represents about 1 trillion bytes (1,009,511,627,776 bytes). 1 TB equals about 500,000,000 pages of text.
8) Peta Byte : A Peta Byte (PB) represents about 1 quadrillion bytes (1,048,576 Giga Bytes).
9) Exa byte: An Exa byte(EB) could be a large unit of computer data storage, two to the sixtieth power bytes. The prefix exa means one billion billion, or on quintillion, which may be a decimal term. Two to the sixtieth power is really 1,152,921,504,606,846,976 bytes in decimal, or somewhat over a quintillion (or ten to the eighteenth power) bytes. it's common to mention that an Exabyte is approximately one quintillion bytes. In decimal terms, an Exabyte could be a billion gigabytes.
10) Zetta byte : A Zetta byte (ZB) is adequate one sextillion bytes. it's commonly abbreviated ZB. At now, no computer has one Zettabyte of storage. it's 1024 Exabytes.
11) Yotta byte : A Yotta byte is capable one septillion bytes. it's commonly abbreviated YB. At this point, no computer has one Zettabyte of storage. it's 1024 Zettabytes.
