The smallest unit that constitutes memory is "Byte". The smallest unit for the CPU to access memory is a "Byte" consisting of an 8-bit binary number. It is a unit of measurement used by computer information technology to measure storage capacity; each "byte" has a sequential number, called "address". Bytes are often abbreviated as "B" and bits are often abbreviated as a lowercase "b". The size of computer memory is usually expressed in bytes.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

In computer hardware technology, the smallest unit that constitutes memory is "Byte".

In an electronic computer, the smallest unit of representation of information is a binary "bit", which can store a binary "0" or "1". The smallest unit for the CPU to access memory is an 8-bit binary number. "Byte". Each "byte" has a sequential number called an "address".

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 an unsigned type from 0-255, so it cannot represent negative numbers.

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.

Byte is usually abbreviated as "B", and bit is usually abbreviated as lowercase "b". The size of computer memory is usually expressed in bytes.

The commonly used units of storage capacity in computers are: B (byte), KB (kilobyte), MB (megabyte), GB (gigabyte). The relationship between them is:

  • 1 byte (Byte) = 8 binary bits (bits);

  • 1KB = 1024B;

  • 1MB=1024KB;

  • 1GB=1024MB.
