This article will explain in detail the reason why a byte in the computer is 8 bits. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The reason why a byte is 8 bits: because it is 128 characters and 128 is 100000000, [System/360] lays the foundation for the character storage unit to be 8 bits long, which is the origin of [1 byte = 8 bits].

Because it is 128 characters, 128 is 100000000.

About bytes:

1. The original intention is to represent a complete character. The initial computer performance and storage capacity are relatively poor, so the widespread use of 4-bit BCD coding (this code appeared earlier than computers, was first used in punch cards).

2. System/360 lays the foundation for the character storage unit to be 8 bits long, which is the origin of 1 byte = 8 bits.

3. Computers use binary systems to store information, which is determined by the laws of nature, and it is estimated that only quantum computers can break through this limit. therefore, a minimum unit of information in the computer had better be 2, 4, 8, 16, 32, 64 bytes, which is convenient for calculation, writing and statistics in the computer.

Other:

1. The word Byte indicates how much bit it takes to encode a character. However, in the 1960s, System/360 of IBM was encoded by EBCDIC, and the ASCII coding standard was also established at that time. Although there are differences between the two standards, they both use 8 bit to represent a character. These two standards are widely used, so up to now a byte has no ambiguity, that is, 8bits.

2. 1B (Byte) = 8b (bit)

1KB=1024B

1MB=1024KB

1GB=1024MB .
