Main technical indexes of computer

(1) word length: refers to the number of bits in the register in the computer. The longer the word length, the larger the range of representation numbers, that is, the more effective digits, the higher the calculation accuracy.

(2) Operation speed: an index indicating the operation speed of an electronic computer, expressed by the number of executable instructions per second, and the unit is "times per second".

(3) Storage capacity: refers to the number of bits or instructions that can be registered in the memory, that is, the ability of the memory to store binary information.

(4) Access cycle: refers to the time required for a complete memory access operation. The access period largely determines the operation speed of the computer, and the shorter the better.

Extended data

The research on the performance evaluation technology of computer's main technical indexes makes the performance become a measurable and evaluable quantitative objective index, and the method to obtain relevant performance information from the system itself or from the system model. The former is measurement technology, while the latter includes simulation technology and analysis technology.

Performance evaluation is usually combined with cost analysis to obtain quantitative values of various system performance and performance-price ratio, so as to guide the design and improvement of new computer systems and computer application systems, including selecting computer types and models and determining system configuration.
