In a digital warehouse unit, data and information room measured by how much room it rectal on gadgets like a computer hard drive. If you discuss around storage unit with an IT specialist or executive, you could hear words choose bits, bytes, megs, and also gigabytes, etc.
You are watching: Smallest unit of data a computer can process
You can obtain swept increase in data warehouse jargon, especially when you’re talking around different varieties of warehouse units. Bits vs. Bytes: what’s the difference? i beg your pardon is larger, megabytes or gigabytes? how do terabytes and also kilobytes differ? To aid you digest these concepts, we have detailed you with this resource.
In this section, us will define what a warehouse unit is and how it varies in dimension from the tiny little bit (b) to the giant Yottabyte (YB).
Different types of storage Unit in Computer- the smallest to Biggest
The the smallest unit the data in a computer is dubbed Bit (Binary Digit). A bit has actually a single binary value, either 0 or 1. In most computer system systems, there room eight bits in a byte. The value of a little is usually stored as either over or below a designated level of electrical charge in a single capacitor in ~ a storage device.
Half a byte (four bits) is called a nibble.
In most computer system systems, a byte is a unit that data that is eight binary digits long. A byte is a unit most computers use to stand for a character such as a letter, number, or typographic prize (for example, “g”, “5”, or “?”). A byte can also hold a cable of bits that must be provided in some larger unit the application functions (for example, the currently of bits the constitute a visual picture for a regime that display screens images or the wire of bits the constitutes the device code the a computer program).
In some computer systems, 4 bytes constitute a word, a unit that a computer processor deserve to be designed to handle effectively as it reads and also processes every instruction. Some computer system processors can handle two-byte or single-byte instructions.
A byte is abbreviated with a “B”. (A bit is abbreviated through a small “b”). Computer storage is generally measured in byte multiples. Because that example, one 820 MB difficult drive holds a in the name 820 million bytes – or megabytes – the data. Byte multiples are based upon powers the 2 and are generally expressed as a “rounded off” decimal number. For example, one megabyte (“one million bytes”) is in reality 1,048,576 (decimal) bytes.
In some systems, the term octet is provided for an eight-bit unit instead of byte. In many systems, 4 eight-bit bytes or octets type a 32-bit word. In together systems, indict lengths are periodically expressed together full-word (32 bits in length) or half-word (16 bits in length).
A Kilobyte (kb or Kbyte) is roughly a thousands bytes (actually, 2 come the 10th power, or decimal 1,024 bytes).
As a measure of computer system processor storage and also real and also virtual memory, a megabyte (abbreviated MB) is 2 to the 20th strength byte or 1,048,576 bytes in decimal notation.
A Gigabyte (pronounced Gig-a-bite with difficult G’s) is a measure of computer data warehouse capacity and is “roughly” a billion bytes. A gigabyte is two to the 30th strength or 1,073,741,824 in decimal notation.
A Terabyte is a measure up of computer storage capacity and is 2 come the 40th strength of 1024 gigabytes.
A Petabyte (PB) is a measure of memory or storage capacity and is 2 to the 50th strength bytes or, in decimal, around a thousand terabytes (1024 terabytes).
An Exabyte (EB) is a large unit of computer system data storage, two to the sixtieth power bytes. The prefix exa means one exchange rate billion, or top top quintillion, i beg your pardon is a decimal term. Two to the sixtieth power is actually 1,152,921,504,606,846,976 bytes in decimal, or rather over a quintillion (or ten to the eighteenth power) bytes. It is usual to say the an Exabyte is approximately one quintillion bytes. In decimal terms, an Exabyte is a billion gigabytes.
A Zettabyte (ZB) is equal to one sextillion bytes. That is frequently abbreviated ZB. At this time, no computer has one Zettabyte that storage. It has 1024 Exabytes.

A Yottabyte is equal to one septillion bytes. The is generally abbreviated YB. In ~ this time, no computer system has one Zettabyte the storage. It has 1024 Zettabytes.
