And as computers spread, we're also swimming in the great web world with keyboard knocks and mouse moves. But while enjoying the convenience of computers, you also suffer from the pain caused by computer viruses. We will now summarize the knowledge points of the computer virus examination in the enterprise examinations, with a view to helping you learn。
What's a computer virus
In short, a computer virus is a command or program code capable of destroying computer functionality. What would happen to the virus in the computer? And if your computer is sometimes a dead machine, sudden cartons or blue screens, sudden automatic shutdowns or data loss for no reason, it's probably your computer. Computer viruses are uniquely replicative and can spread rapidly, but are often difficult to eradicate。
Ii. How to prevent computer viruses
For people who often use computers, computer viruses are like a time bomb. However, computer viruses are not uncontrollable, and there are ways to reduce the probability of viruses in computers。
(i) installation and maintenance of up-to-date versions of poison-killing software, care not to install competing poison-killing software, periodic virus-killing of computers and initiation of poison-killing software testing on the internet;
(ii) development of good internet access habits, access to regular websites and the free opening of undisclosed mail, websites, links, documents, etc.;
(iii) when using various mobile storages, kill the virus and ensure that it is clean and available。
Iii. Question of the existence of computer viruses
(i) computer viruses are self-generated as biological viruses. In fact, computer viruses, although as destructive and contagious as biological viruses, are artificially created procedures and are an enforceable code;
(ii) as long as poison-free software is installed, the virus will not be detected. In fact, the installation of poison-killing software does not mean 100 per cent safety, and the meaning of poison-killing software is defence, greater than murder;
(iii) there must be no virus as long as the computer is not connected. Computer viruses can be transmitted in many ways, in addition to via the internet, through mobile storage devices: ucds, cds, diskettes, mobile hard drives, etc., can be the routes through which viruses can be transmitted。
Iv. Summary
The following statement of computer viruses is correct:
A. Installation of poison software to stop all computer viruses
B. The virus was created automatically by windows
C. Computer viruses are a set of computer commands or program codes
D. The virus will not be infected as long as it is not online
[chinese public answer] c. Parsing: computer viruses are computer programs that are dependent on other programs to reproduce themselves and that can modify normal programs, disrupt their functionality, or copy and hack into other programs to destroy them. A error, poison-killing software is not everything, and the virus is constantly evolving. B error, c error, computer virus is a set of computer commands or program codes created by humans. The d error is that the virus can be transmitted in many ways and can be poisoned without the internet. The answer to this question is c。
It is not so difficult for this topic, which primarily looks at the knowledge of the computer-related aspects of common-sense technology, to be generally judged by the type of subject in common-sense judgement, to make the right choices if you have some basic computer knowledge。
