What are the main performance indicators of a computer? Please give a brief answer.

The main performance indicators of the computer are:

1) operation speed. Operation speed is an important index to measure the performance of a computer.

2) word length. Generally speaking, computers process binary numbers at the same time.

3) Access cycle: The time required for a "read" or "write" operation of the memory is called the access time (or read-write time) of the memory, and two independent "read" or "write" operations are started continuously (such as two consecutive "read" operations).

The shortest time required is called access cycle (or storage cycle)

4) Operation speed: refers to the number of instructions that the computer can execute per second, generally in MIPS.

5) Capacity: One of the factors to measure memory performance is its capacity. At present, the standard memory capacity of notebook computers is usually 2GB or 4GB.

6) Main frequency: refers to the clock frequency of the computer, expressed in MHz.
