What is the basic unit of a computer bytes?
Byte is the basic unit of computer data storage.
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 byte stores an 8-bit unsigned number, and the stored value range is 0-255. Like characters, byte type variables only require one byte (8 bits) of memory space to store.
Byte is 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 usually abbreviated as lowercase "b". The size of computer memory is usually expressed in bytes.
Data type
Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types in some computer programming languages. and language characters. Byte is an unsigned type from 0-255, so it cannot represent negative numbers.
