What this article shares with you is about what computer viruses cannot spread. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Computer viruses cannot be spread by "operators carrying infectious diseases". Computer virus is a kind of computer program, which belongs to data, and the transmission of data (virus) must pass through the transmission medium (floppy disk, CD-ROM, network, etc.). Without the transmission medium, the virus cannot spread.

Correlation

Computer viruses cannot be transmitted through ().

A. Network

B. floppy disk

C. operators carrying infectious diseases

D. CD-ROM

Correct answer: C

Answer analysis

[examination site] computer virus prevention

Computer viruses are usually transmitted by floppy disks, CD-ROMs and networks. Computer viruses cannot be spread by operators who carry infectious diseases.

Extended data:

Computer virus (Computer Virus) is a group of computer instructions or program codes that programmers insert into computer programs that destroy computer functions or data, can affect the use of the computer, and can copy themselves.

Computer viruses are contagious, concealed, infectious, latent, excitable, expressive or destructive. The life cycle of computer virus: development period, → infection period, → incubation period, → attack period, → discovery period, → digestion stage, → extinction period.

The route of transmission of computer poison:

Computer viruses have their own transmission modes and different transmission paths. The main function of the computer itself is its own replication and transmission, which means that the spread of computer viruses is very easy, usually in an environment where data can be exchanged. There are three main types of computer virus transmission:

(1) virus transmission through mobile storage devices: such as USB disk, CD, floppy disk, mobile hard disk, etc., can be the path of virus transmission, and because they are often moved and used, they are more likely to be favored by computer viruses and become carriers of computer viruses.

(2) spread through the network: the network methods described here are also different. Web pages, e-mail, QQ, BBS and so on can all be the ways to spread computer viruses through the network. Especially in recent years, with the development of network technology and the running frequency of the Internet, the speed of computer viruses is getting faster and faster, and the scope is gradually expanding.

(3) take advantage of the weakness of computer systems and application software to spread: in recent years, more and more computer viruses spread out by taking advantage of the shortcomings of application systems and software applications, so this approach is also divided into the basic mode of transmission of computer viruses.
