This article will explain in detail what are the characteristics of machine language in computers. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The first generation of computers mainly used machine language; machine language is a system of instruction sets, called machine codes, that can be directly interpreted by the computer's CPU.

The first generation of computers mainly used machine language.

Machine language (machine language) is a system of instruction sets. This set of instructions, called machine code (machine code), is data that can be directly interpreted by the computer's CPU.

Machine language has the following characteristics

1. Machine language is closely related to computer hardware structure.

Different computer hardware structures have different machine languages. In the computer hardware structure with CPU as the core, different CPU has different machine languages, which are closely related to the computer hardware structure.

2. Binary number representation

In the machine language, the instruction opcode, the address of the storage unit storing the operands, and the operands are all represented by binary numbers. CPU will access the contents read by the memory as instructions with the value of the program counter as the address, and take the address of the operands given in the instruction. Or use the value of address register B as the address to access the contents read by the memory as operands. CPU is responsible for distinguishing instructions from operands, and binary numbers that represent instructions and operands cannot distinguish between the two.

3. When designing a program, it is necessary to synchronously arrange the location of instructions and operands in memory.

Because the operation instruction needs to specify the address of the memory unit for storing another Operand, and the control instruction needs to specify the address of the memory unit for storing the first instruction in another program or loop without executing instructions sequentially, therefore, the process of designing a program is also the process of arranging the location of instructions and operands in memory.

4. Each instruction can only complete the function of simple operation

Each instruction in the machine language can only perform simple operations. It is difficult to write a program with machine language to complete a complex operation process, and a machine language program that contains only four operation expressions is relatively complex. You can try to write a machine language program with model machine instructions to complete the expression: 7: 8 + (21-17) * 5-(7: 21) / 6.
