What is the most basic capacity unit used to represent the size of storage space in a computer?

The most basic capacity unit used to represent the size of storage space in a computer is byte, which is the unit for transmitting information through the network (or storing information in hard disk or memory).

The smallest unit of data in a computer is bits, and every eight bits make up a byte, but the most basic unit of storage capacity is bytes. Byte is a unit of measurement used by computer information technology to measure storage capacity and transmission capacity. 1 byte equals 8-bit binary. Generally speaking, numbers, letters and English symbols account for 1 byte, and Chinese characters and Chinese symbols account for 2 bytes.

Two concepts of BIT;

1) Computer terminology is a kind of information unit, which is transliterated from English BIT. One bit of a binary number contains one bit of information, for example, the binary number 0 100 is four bits.

2) A bit in a binary number is the smallest unit of information. In digital acoustics, audio signals are represented by electric pulses, "1" represents pulses, and "0" represents pulse intervals. If the information of each point on the waveform is represented by a four-bit code, it is called four bits. The higher the number of bits, the more accurate the expression of analog signals and the stronger the ability to restore audio signals.

Bit concept

In the binary number system, every 0 or 1 is a bit, and one bit is the smallest unit of data storage. In which 8 bits are called a byte. The number of CPU bits in a computer refers to the maximum number of bits that the CPU can handle at a time. For example, the CPU of a 32-bit computer can process up to 32-bit data at a time.

Extended data:

Data storage is based on "bytes" and data transmission is based on "bits". One bit represents a 0 or 1 (that is, binary), and every 8 bits (bit, abbreviated as B) form a Byte (abbreviated as B), which is

Hard disk manufacturers calculate in GB (decimal, that is, the third power of 10 = 1000, such as 1000 KB), and computers (operating systems) calculate in GIB (binary, that is, 2 to the power of 10, such as 65438). Domestic users generally understand it as1MiB =1m =1024kb, so in order to understand China culture conveniently, MIB can be translated into MB.

Similarly, according to the different understanding of the size of 1MB between hard disk manufacturers and users, many hard disks with 160G are calculated according to the actual computer size of 1MB = 1024 kb, and the actual capacity is less than 160G, which can also explain why the newly bought hard disks are not as big as it indicates.
