When a floppy disk is written protection, it can only be read, not written, why is it a way to preve

Well, the spread of the virus is actually spreading **files, and **files will be poisoned when they are loaded into the system to run. When the floppy disk is write protected, the data can only be output and not input (that is, it cannot add things to the floppy disk), so that the virus cannot be transmitted. If you can't get it, you can't be infected by the virus, and all of this is a way to prevent the virus.

A floppy disk drive is an indispensable part of the computer, which can boot the computer for us when necessary, and can also be used to transfer and back up some relatively small files. Before introducing floppy drives, let's get to know floppy disks. Meet Floppy Disks:

The floppy disks we see now are all inches, usually referred to as 3 inches. The 3-inch floppy disk has a plastic shell, which is relatively hard, and its function is to protect the platter inside. The platter is coated with a layer of magnetic material (such as iron oxide), which is the medium through which data is recorded.

There is a protective layer between the housing and the platter to prevent the abrasion of the enclosure to the platter. Floppy disks provide a simple way to write protection, 3-inch disks are achieved by a block, unplug them, open the square hole is write protection. Otherwise, write protection is enabled, and data can be written to the file.

Write protection is a very useful feature to prevent miswrites and viruses. When using, it is best to put some important floppy disks such as program installation disks and data backup disks in a write-protected state. When the floppy disk is inserted into the drive, there is a reversal, and the 3-inch disk is generally not inserted incorrectly (it cannot be inserted if it is misplaced).

The floppy disk capacity that we usually use is:

Hello: Because a virus is also a program, viruses exist in your memory. If the virus is to spread, it will have to copy itself to a removable memory (USB stick). And if your USB flash drive is forbidden to write, then the virus cannot be replicated and cannot spread.

Ways to protect against computer viruses:

a. Establish rules and regulations for virus prevention and control, and strictly manage them.

b. Establish a virus prevention and emergency response system.

c. Carry out computer security education and improve the awareness of security precautions.

d. Conduct risk assessment of the system.

e. Choose virus prevention and control products certified by the Ministry of Public Security.

f. Correct configuration and use of virus prevention and control products.

g. Configure the system correctly to reduce virus invasion incidents.

h. Regularly inspect sensitive documents.

i. Conduct security assessments in a timely manner and adjust various virus prevention and control strategies.

j. Establish a virus accident analysis system.

k. Ensure recovery and reduce losses.

Hello 1, there are very few viruses for floppy disks at present, and the viruses themselves are larger than the software memory.

2, but there is still a chance that the floppy disk will be poisoned after writing protection, because the copy file also has to be opened.

4. PC Manager has 16 layers of real-time protection function, which can protect computer security from Trojan viruses from Internet security, application entrance, and system bottom layer. The unique cloud intelligent early warning system can detect and block the destructive behavior of Trojans at the early stage of Trojan activities, and kill the latest popular Trojans in seconds through cloud scanning and killing technology.

If you have any other questions and problems, please come to the computer manager business platform again to ask questions, and we will do our best to answer your questions.

That's right, of course. Because with write-protection, no information can be recorded on the floppy disk, and you will not be able to use and see all the data on the disk. The protection of floppy disks in this regard is still very good, it is recommended that when not in use, add protection, it is very safe, and you don't have to worry about viruses.

Answer]: 1 Answer].

Computer security precautions.

Analysis】 Write protection means that the floppy disk can only read and cannot be written by the Chinese segment, which can prevent the floppy disk from being infected with viruses.
