Multiple choice question 1 point In which of the following wars, the use of computer viruses was par

b.Kosovo War.

In the Kosovo war, the scale and effectiveness of cyber warfare have made people re-realize its importance in modern warfare. During the war, the Federal Republic of Yugoslavia used a variety of computer viruses and organizational "hackers" to carry out cyber attacks, causing some NATO troops to be blocked by spam information, and some computer network systems were paralyzed for a time. On the one hand, NATO has strengthened its cyber protection measures, and on the other hand, it has carried out cyber counterattack warfare, sending a large number of viruses and deceptive information to the Yugoslav military's computer network and communication system for interference.

This war is a classic example of cyber warfare, and it has been written into the textbooks of major military academies.

Iraq War The United States unleashed a computer virus that destroyed Iraq's air defenses.

b Because he was using the printer virus to attack the power grid.

Answer B is false, the main objects of computer virus destruction are programs and data.

A computer virus is a set of computer instructions or programs inserted by the compiler into a computer program that can destroy computer functions or data, affect the use of the computer, and can replicate itself.

Computer viruses are transmissible, hidden, infectious, latent, excitable, expressive, or destructive. The life cycle of a computer virus: development period, infectious period, incubation period, attack period, discovery period, digestion period, and extinction period.

A computer virus is a program that executes code. Just like biological viruses, they have the characteristics of biological viruses such as self-reproduction, mutual infection, and activation and regeneration.

Computer viruses have a unique ability to replicate, and they can spread quickly and often hard**. They can attach themselves to various types of files, and they spread along with files as they are copied or transferred from one user to another.

The main objects of computer virus destruction are programs and data.

Answer]: Antivirus software can detect, protect, and take action to remove or remove malware programs, such as viruses and worms. Therefore, installing and upgrading antivirus software in time can effectively prevent and control computer viruses.

Answer]: C solves the problem by elimination; A, B, and D can all prevent computer viruses, and C is not feasible, so C is excluded.

In the following narrative about computer viruses, the correct one is ().

a.Computer viruses, like biological viruses, can endanger personal safety.

b.A computer virus is a program.

c.If you delete all files that are infected with the virus, the virus will also be deleted.

d.In order to prevent the intrusion of viruses, the disk should not be used.

Correct answer: B

The following is the statement about computer viruses, where (computer viruses are created due to the mispreparation of programs) is incorrect.

As a medical worker, I once again declare that "virus" is not synonymous with computer virus, "computer virus" is just a metaphor for biological "virus", please improve the relevant content distribution of virus entries in the encyclopedia, and let users get comprehensive information when searching.

Computer virus is clearly defined in the Regulations of the People's Republic of China on the Security Protection of Computer Information Systems, and refers to "a set of computer instructions or programs inserted into a computer program by the compiler that destroys computer functions or destroys data, affects the use of the computer and can replicate itself".

Unlike "viruses" in medicine, computer viruses are not naturally occurring and are a set of instructions or programs that some people have compiled to take advantage of the inherent vulnerabilities of computer software and hardware**. It can be latent in the computer's storage medium (or program) in some way, and when certain conditions are reached, it will be activated, and it will be put into other programs by modifying the exact copy of itself or the form that may evolve into other programs.

The so-called virus is artificially caused and is very harmful to other users.

Generated:

Viruses are not sudden or accidental.

The virus comes from a chance event, when the researchers in order to calculate the number of people on the Internet at that time, but it "multiplied" itself and caused the entire server to crash and blockage, sometimes a sudden power outage and accidental error, will produce some garbled and random instructions in the computer's disk and memory, but these ** are disordered and chaotic, the virus is a relatively perfect, delicate and rigorous **, organized in strict order.

Adapting to and cooperating with the network environment of the system where the manuscript loss is located, the virus will not be formed by chance, and it needs to have a certain length, which is impossible to generate randomly from the probability point of view.

From a large number of statistical analysis, the main situation of the author of the virus is filial piety and purpose: some genius programmers in order to show themselves and prove their ability, out of dissatisfaction with their bosses, for curiosity, for revenge, for congratulations and courtship, in order to get control passwords, for the software to get paid traps, etc. Of course, there are also political, military, religious, ethnic.

Patents and other aspects of the virus are specially written, which also include a number of virus research institutes and hackers to test viruses.

a.One of the characteristics of computer viruses is that they are immune.

b.A computer virus is a kind of Duan Hui applet with logical errors.

c.Anti-virus software must be upgraded as new viruses emerge to improve the ability to detect and kill viruses.

d.A computer that has been infected with a computer virus is immune to the virus.

Correct answer: c
