This article mainly introduces what are the storage units of data in computers, which have certain reference value. Interested friends can refer to them. I hope that after reading this article, you will gain a lot. Let Xiaobian take you to understand them together.

The storage unit of data in a computer: 1. Bit is the smallest unit that represents the amount of information, and there are only two binary states of 0 and 1;2. Byte is the basic unit for storing data;3. Word, two bytes are called a word;4. KB;5. MB;6. GB;7. TB.

A storage unit is a unit of measurement. A specific quantity or standard used as a point of record in a field. A multiple of this point is used to define another point, which is synonymous with a unit of counting or storage.

Inside a computer, information is stored, calculated, processed, and transmitted in binary form. Information storage units are bits, bytes and words. Storage capacity units of various storage devices are KB, MB, GB and TB.

basic storage unit

Bit: A binary digit, either 0 or 1, that is the smallest unit of data in a computer.

Byte (B): The basic unit of data in a computer, consisting of 8 bits each. It takes at least one byte to store and process all kinds of information in a computer. For example, an ASCII code is represented by one byte, and a Chinese character is represented by two bytes.

Word: Two bytes are called a word. The storage unit of Chinese characters is one character.

Extended storage unit

In the storage capacity representation of various storage media (such as memory, hard disk, optical disk, etc.) of computers, the storage units that the user touches are not bits, bytes, and words, but KB, MB, GB, etc., but this is not a new storage unit, but based on byte conversion.

KB: Early floppies were available in 360KB and 720KB sizes, but floppies are rarely used.

MB: The memory of early microcomputers was 128MB, 256MB, 512MB, and the current memory is 1 GB, 2 GB, or more.

GB: Early minicomputers had 60GB, 80GB hard disks, and today they are all 500GB, 1TB, or even larger.

TB: At present, the storage capacity of personal microcomputers can also reach this level, and as servers or specialized computers, such a large storage capacity is indispensable.

alternate units

Common storage units for computers:

8 bit = 1 Byte

1024 B = 1 KB (KiloByte)

1024 KB = 1 MB (MegaByte)

1024 MB = 1 GB (GigaByte)

1024 GB = 1 TB (TeraByte)

1024 TB = 1 PB (PetaByte)

1024 PB = 1 EB (ExaByte)

1024 EB = 1 ZetaByte

1024 ZB = 1 YB (YottaByte)

1024 YB = 1BB (Brontobyte) per byte

1024 BB = 1 NB (NonaByte)

1024 NB = 1 DB (DoggaByte)

Thank you for reading this article carefully. I hope the article "What are the storage units of data in computers" shared by Xiaobian will be helpful to everyone. At the same time, I hope everyone will support you more, pay attention to the industry information channel, and more relevant knowledge is waiting for you to learn!
