Computer viruses cannot destroy the data and files in the CD-ROM, because the data and files in the CD-ROM are read-only and cannot be written again, so the virus cannot modify it, so it cannot destroy any document.
#Computer viruses cannot destroy data and files in CD-ROMs.
Because the data and files in the CD-ROM are read-only.
Related introduction:
Computer viruses are contagious, covert, infectious, latent, excitable, expressive or destructive. The life cycle of a computer virus: development period → infection period → incubation period → attack period → discovery period → digestion period → extinction period.
A computer virus is a program, a piece of executable code. Just like biological viruses, they have the characteristics of self-reproduction, mutual infection, and activation of regeneration.
Computer viruses have unique replication capabilities. They can spread quickly and are often difficult to eradicate. They can attach themselves to various types of files and spread with them when they are copied or transferred from one user to another.
The computer is composed of internal circuits that can complete various arithmetic operations at high speed and accurately. The computing speed of today's computer systems has reached trillions of operations per second, and microcomputers can also reach more than 100 million operations per second, enabling a large number of complex scientific computing problems to be solved. For example: the calculation of satellite orbits, calculations of large dams, and 24-hour weather calculations take years or even decades, but in modern society, they can be completed in just a few minutes using computers.
Extended information:
The virus attaches to the storage media floppy disk, hard disk, etc. to form the source of infection. The virus transmission vector is determined by the work environment. Virus activation is placing the virus into memory and setting a trigger condition, which can be the clock, system date, user identifier, or system communication. When conditions are ripe, the virus begins to replicate itself in the infected object and perform various destructive activities.
Virus infection is an important indicator of virus performance. During the propagation process, the virus copies itself to the infected object.
There are many kinds of computer viruses, and they are very complex. According to the different methods and characteristics of computer viruses, there can be many different classification methods. At the same time, the same computer virus can belong to different types of computer viruses according to different classification methods.
