Compared with previous computing tools, today's computers have the following characteristics: (). ?

A.it has a memory function. It can store a large amount of information for users to search and query at any time.

B. Automatically calculate according to the program, completely replacing human mental work.

C. it has the ability of logical judgment, so the computer has all the intelligence of human beings.

D. all of the above are true.

Answer analysis a

[Analysis] Compared with previous computing tools, today's computers have a memory function, which can store a large amount of information for users to retrieve and query at any time. Therefore, the statement of option A is correct. ?

At present, although the computer runs automatically according to the program, the program is written by people, so the computer can not completely replace people's mental work. So option b is wrong. Computers have the ability of logical judgment, but they can't be said to have all the intelligence of human beings. So option c is also wrong.

Computer (computer)

Computer, commonly known as computer, is a modern electronic computer for high-speed calculation, which can be used for numerical calculation, logical calculation and memory storage. It is a modern intelligent electronic device that can run according to the program and automatically process massive data at high speed.

It consists of hardware system and software system, and a computer without any software is called bare metal. It can be divided into five categories: supercomputer, industrial control computer, network computer, personal computer and embedded computer. More advanced computers include biological computers, photonic computers and quantum computers.
