The memory used to store the currently running application and corresponding data is "RAM". RAM refers to random access memory, which is an internal memory that directly exchanges data with the CPU. It can be read and written at any time and is very fast. It is usually used as a temporary data storage medium for the operating system or other running programs. RAM stores currently used programs, data, intermediate results, and data exchanged with external memory.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The memory used to store the currently running application and its corresponding data is ______.
A. RAM
B. Hard drive
C. ROM
D. CD-ROM
Answer: A
[Analysis]: RAM stores currently used programs, data, and intermediate files Results and data exchanged with external memory; ROM is mainly used to store fixed system programs and data that control the computer; hard disk storage speed is slower than RAM; CD-ROM is called a read-only optical disk, so it cannot be used for storage Currently running programs and data.
RAM (referring to random access memory)
Random Access Memory (English: Random Access Memory, abbreviation: RAM), also called Main memory is the internal memory that exchanges data directly with the CPU. It can be read and written at any time (except when refreshing), and it is very fast. It is often used as a temporary data storage medium for the operating system or other running programs. When RAM is working, information can be written (stored) or read (retrieved) from any specified address at any time. The biggest difference between it and ROM is the volatility of data, that is, the stored data will be lost once the power is turned off. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.
