What is the internal memory of a microcomputer?
The internal memory of the microcomputer is "byte addressable". The internal memory of a microcomputer usually consists of 8 binary bits forming a storage unit, and each byte is assigned a number, that is, an address.
Microcomputer is referred to as "microcomputer" or "microcomputer". Because it has certain functions of the human brain, it is also called "microcomputer". Microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on a microprocessor, equipped with internal memory, input and output (I/0) interface circuits and corresponding auxiliary circuits.
The internal memory of a microcomputer usually consists of 8 binary bits forming a storage unit, and each byte is assigned a number, that is, an address.
Byte addressing: The memory is divided into several units, each unit has a capacity of 1 byte and is numbered (address) starting from 0.
For a 2M x 32-bit memory, its capacity is 8MB
The CPU addressing size is 1 byte (8 bits) at a time, with a total of 8M*8bit/8bit = 8M units , that is, addressing 2^23 memory cells, the address bus is 23 bits.

Can be accessed directly. Internal memory, also called memory, is the bridge between external memory and the CPU. All programs in the computer run in memory. The function of memory is to temporarily store calculation data in the CPU and data exchanged with external memories such as hard disks. As long as the computer is running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation; when the calculation is completed, the CPU will transmit the results. The operation of the memory also determines the stable operation of the computer.

Microcomputers with microprocessors as the core belong to the 4th generation of computers. Transistors are the characteristics of the second generation computers, integrated circuits are the characteristics of the third generation computers, vacuum tubes are the characteristics of the first generation computers, and large-scale integrated circuits are the characteristics of the fourth generation computers; and microprocessors are composed of one or a few A central processing unit composed of several large-scale integrated circuits.

The basic components of a microcomputer hardware system include CPU, memory, input devices and output devices. The microcomputer hardware system contains five important components: arithmetic unit, controller, memory, input device, and output device; and the controller and arithmetic unit together form the central processing unit (CPU). The main function of the arithmetic unit is to calculate and process data and information; the controller can be regarded as the brain and command center of the computer. It allows the various components of the computer to complete instructions in an orderly manner by integrating and analyzing relevant data and information.

The alt key on the keyboard used by microcomputers is called the "alternative shift key"; the alt key is one of the special keys of the keyboard, used in combination with other keys to indicate special operations; in Windows, it is also used alone as a menu bar used for mobile operations.

The development of microcomputers is characterized by the development of microprocessors, because microprocessors are the core of all computer activities; microprocessors can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components. It is the computing control part of the microcomputer.

The arithmetic unit in a microcomputer is the core component used to perform numerical calculations and logical operations. Its functions are: 1. The arithmetic unit is used to perform numerical calculations. Through the operation of the arithmetic unit, the computer can quickly complete a large number of mathematical operations, thereby improving calculations. Efficiency and calculation accuracy; 2. The arithmetic unit is also responsible for performing logical operations. Through logical operations, the arithmetic unit can judge the input logical values and generate corresponding logical results; 3. The arithmetic unit also has the function of memory access, etc.

The shift key on a microcomputer keyboard is called the shift key. Microcomputer is a small electronic computer composed of large-scale integrated circuits. It has the characteristics of small size, high flexibility, low price and easy use.

The memory that the CPU can directly access is: internal memory. Internal memory, also known as memory, is a storage space that the CPU can directly address and is made of semiconductor devices. Internal memory is the bridge between external memory and the CPU. All programs in the computer run in memory. As long as the computer is running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation; when the calculation is completed, the CPU will transmit the results. The operation of the memory also determines the stable operation of the computer.
