This article is about the difference between hard disk and memory. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Differences: 1, memory is the place where the computer runs, the hard disk is used to store temporarily unused information; 2, the information in the memory will disappear with the power loss, and the information in the hard disk can be preserved for a long time. The performance index of hard disk, including hard disk capacity, hard disk speed, hard disk speed, interface, cache, single disk capacity of hard disk, etc.; the performance index of memory is capacity, frequency, delay value.

Memory: memory, also known as main memory, the programs in the computer are run in memory, only the computer is running, the computer CPU will transfer the required calculation data to memory for operation. Memory is usually divided into random access memory (RAM), read-only memory (ROM) and cache (CACHE).

Hard disk: from the structural system of the computer, the hard disk should be regarded as the "external memory" of the computer.

The difference between memory and hard disk

The main differences between memory and hard disk are as follows:

1. Memory is the place where the computer runs, and the hard disk is used to store information that is temporarily unused.

2. The memory is made of semiconductor materials and the hard disk is made of magnetic materials.

3. The information in the memory will disappear with the power loss, and the information in the hard disk can be saved for a long time.

Performance indicators of memory and hard disk

The performance index of hard disk, including hard disk capacity, hard disk speed, hard disk speed, interface, cache, hard disk capacity and so on.

Performance parameters of memory: capacity, frequency, delay value.
