计算机导论考试简答题（Introduction to computer test）

9 、 what components do you need to assemble a personal computer?

Please give a list of the components for assembling the

computer.

Answer: motherboards, graphics cards, network cards, memory,

hard disk, chassis, power, keyboard, mouse, CD-ROM, monitor,

CPU. Graphics card and network card are integrated on the

motherboard, you can also buy independent, as well as audio

equipment.

10. For structured programming languages, there are three basic

program structures. What are the three basic program structures,

please give an example.

Answer: sequential structure, choice structure, cyclic

structure;

1., sequential structure: from top to bottom in order to

perform.

2. selection structure: statements with if

The 3. loop structure: statements with for and while

11. The file is a collection of related data stored in memory

on the computer. What is the file naming rule? How does the

operating system organize files? What are the advantages of

this organizational approach?

Answer: the file name of a file consists of two parts: the main file name and the extension. When extensions are used, numbers

are separated.

Files in the same folder are not allowed to have the same file

name,

Organization: organize documents at different levels

Advantages: it will greatly improve the efficiency of document

management, especially the efficiency of file search.

12, for the computer system? Neumann system, let the computer

to complete a task, which can be divided into several steps?

Answer: input - "storage -" control - "operation -" output,

15, what are the main technical measures to ensure the security

of computer systems?

Answer: three aspects of technical safety, management safety,

legal security.

Anti virus technology, anti hacker technology, firewall

technology, intrusion detection technology, data encryption

technology, security authentication technology

16, a brief description of the development process of

computers.

Answer: ENIAC just a few decades after birth, the development

of computers by leaps and bounds. The main electronic devices have been using vacuum tubes, transistors, medium and small

scale integrated circuits and large scale and very large scale

integrated circuits, which have led to several upgrading of

computers.

The first generation (1946~1957) is a computer, it is the basic

electronic components electronic tube, memory using mercury

delay line memory mainly uses a drum, tape, tape cards, etc.

The second generation (1958~1970) was a transistor computer.

A large number of magnetic memory cores made of magnetic

materials are used in memory

The third generation (1963~1970) is an integrated circuit

computer (small scale) basic electronic components third

generation computer circuits are small scale integrated

circuit and medium scale integrated circuits, the further

development of core memory, and start with the better

performance of semiconductor memory

The fourth generation (1971 ~ day ago) is a large scale

integrated circuit computer

Highly integrated semiconductor memory replaces magnetic core

memory.

18, from the user's point of view, what components should be

included in the hardware system of a personal computer?

Answer: monitor, host, key mouse, the host is inside by CPU,

motherboard, power, memory, graphics card (see the user situation, available integration, but also can be used alone),

CD-ROM, chassis, hard disk 8 parts. It's basic, and audio

equipment... And so on

19, Internet is what kind of network, it can provide what

aspects of functional services? What can you get out of it?

Answer: it is a global network of computers that communicate

with each other using public language.

Features: (1) email E_mail (2) remote login Telnet (3) file

transfer FTP; (4) WWW services, some of which are free of charge,

and some services are charged.

21, a brief description of the basic components of the computer,

the main function of each component, as well as the relationship

between the components.

Answer: motherboard: the main body of a PC, the motherboard to

complete the management and coordination of computer systems,

support various CPU, functional cards and the normal operation

of the bus interface

CPU: that is the central processing unit, the core of the whole

system, and the highest unit of execution in the whole system.

It is responsible for the execution of the whole system

instruction, the operation of mathematics and logic, the

storage and transmission of data, and the control of internal

and external input and output.

Chip set: in fact, an integrated circuit chip, it is the
