The basic unit for measuring computer memory capacity is byte. Byte is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and language characters in some computer programming languages. One bit Section stores 8-bit unsigned numbers, and the stored value range is "0-255".

The storage capacity of computer memory refers to the amount of binary information that the memory can store. The basic unit of data storage is B (byte).
Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and language characters in some computer programming languages.
A bit section stores an 8-bit unsigned number, and the stored value range is 0-255. Just like characters, byte type variables only require one byte (8 bits) of memory space to store.
Introduction
Bytes are the unit of binary data. A byte is usually 8 bits long. However, some older computer architectures use different lengths. To avoid confusion, in most international literature the word byte is used instead of byte. In most computer systems, a byte is an 8-bit unit of data. Most computers use a byte to represent a character, number, or other character. A byte can also represent a series of binary bits. In some computer systems, 4 bytes represent a word, which is the unit of data that the computer can efficiently process when executing instructions. Some language descriptions require 2 bytes to represent a character, which is called a double-byte character set. Some processors are capable of handling double-byte or single-byte instructions. Bytes are often abbreviated as "B" and bits are often abbreviated as lowercase "b". The size of computer memory is usually expressed in bytes.
