What is a common security threat that can compromise your computer files?
Maelezo ya Majibu

A common security threat that can compromise your computer files is the use of weak passwords for user accounts and file access.


When you use passwords that are easy to guess, like "123456" or "password," it becomes much easier for unauthorized people to gain access to your computer and files. Weak passwords are like weak locks on a door; they do not provide enough protection against someone trying to break in.


To keep your computer files safe, it is important to use strong passwords. A strong password typically includes a mix of uppercase and lowercase letters, numbers, and special characters. This makes it much harder for someone to guess or crack your password, providing an added layer of security to your computer files.


In contrast, incompatibility with different operating systems, outdated software versions, and physical damage to your hardware do not directly relate to unauthorized access to your files. These factors may cause inconveniences or require software updates or repairs, but they don't specifically involve compromising your file security like weak passwords do.

Viruses, worms and trojan horses are all?           

Maelezo ya Majibu
Viruses, worms, and trojan horses are all examples of malicious software, also known as malware. Malware is software that is designed to harm or exploit a computer system. A virus is a type of malware that infects a computer file and then spreads to other files on the same computer or to other computers on the same network. A worm is similar to a virus in that it can spread from computer to computer, but it does not need to attach itself to a specific file. Instead, it can create its own network connections to spread. A trojan horse is a type of malware that is disguised as a legitimate software program. When the program is installed, the trojan horse is activated and can then steal sensitive information or cause other harm to the computer system. In summary, viruses, worms, and trojan horses are all malicious software that can harm computer systems, and it is important to protect your computer from these types of threats by using anti-virus software and being cautious when downloading and installing programs.
