A computer's storage capacity refers to what it has

The storage capacity of a computer refers to the number of bytes it has. Storage capacity refers to the amount of binary information that the memory can accommodate, expressed by the product of the addressing number of the storage address register MAR in the memory and the number of stored words.

The storage capacity of a computer refers to what it has?

Storage capacity refers to the amount of binary information that the memory can hold, expressed by the product of the addressing number of the storage address register MAR in the memory and the number of stored words.

Storage capacity refers to the maximum amount of data that the portable storage product can store, and is the most critical parameter of the portable storage product. Generally, the capacities of U disks include 1GB, 2GB, 4GB, 8GB, 16GB, 32GB, and 64GB. There are also some products with higher capacity, but the price has exceeded the level that users can accept. Among them, 1GB~2GB portable storage has been basically eliminated by the market; while 4GB~16GB products are the mainstream in the market, with prices within the acceptable range of ordinary users, and they are also the capacity type with the most product types launched by manufacturers; products above 32GB , because the price is expensive, the user group is small, and the product types are also small.

Introduction to bytes:

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 usually abbreviated as lowercase "b". The size of computer memory is usually expressed in bytes.

B and bit

Data storage is in "byte" (Byte), and data transmission is mostly in "bit" "(bit, also known as "bit") is the unit. One bit represents a 0 or 1 (i.e. binary). Every 8 bits (bit, abbreviated as b) form a byte (Byte, abbreviated as B), which is The smallest unit of information.

Word

In a computer, a string of numbers that are processed or calculated as a whole is called a computer word, or word for short. Words are usually divided into bytes (each byte is usually 8 bits). In memory, each cell typically stores one word. Therefore each word is addressable. The length of a word is expressed in digits.

Word length

The number of bits contained in each word of a computer is called the word length. The calculated word length refers to the number of binary digits it can process at one time. Generally, the word length of large computers is 32-64 bits, that of small computers is 12-32 bits, and that of microcomputers is 4-16 bits. Word length is an important factor in measuring computer performance.
