Where are the programs running on the computer stored?
The programs that the computer is running are stored in RAM (memory). RAM is the bridge that communicates with the CPU; all programs in the computer are run in memory, so the performance of the memory has a great impact on the computer.
The program that the computer is running is stored in RAM (memory).
RAM is the bridge that communicates with the CPU. All programs in the computer run in the memory, so the performance of the memory has a great impact on the computer.
As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory 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.
Composition: Memory is composed of memory chips, circuit boards, golden fingers and other parts.
Extended information:
Computer running program:
The whole process can be summarized as compilation, linking, and loading ,implement.
1. Compilation
The compilation process can be divided into two stages: compilation and assembly.
Compilation means that the compiler reads the source program of the character stream, performs lexical and syntactic analysis on it, and converts high-level language instructions into functionally equivalent assembly code.
Assembler converts assembly code into commands that can be executed by the machine. Almost every assembly statement corresponds to a machine instruction.
2. Links
The main content of the link is to handle the mutual reference parts between the modules so that the modules can be correctly connected.
3. Loading
After the program is linked, the executable file is obtained. The next step is to load the executable program into the memory.
Since modern operating systems use paging to manage memory, the operating system only needs to read the file header of the executable file, and then establish a mapping relationship between the executable file and the virtual memory without actually to load the program into memory.
4. Run
The loader copies the code and data in the executable object file from disk to memory, and then runs it by jumping to the first instruction or entry point of the program program.
