Understanding Computer Viruses
A "virus" in computing is a specific type of malicious software (malware) that can have damaging effects on computers and networks. Here’s a detailed explanation of why option 'B' is correct:
Definition of a Virus
- A virus is a program designed to replicate itself and spread from one computer to another.
- It attaches itself to legitimate software or files, enabling it to execute when the infected program runs.
Mechanism of Spreading
- Replication: Once a virus infects a host system, it replicates itself within the system, often corrupting or deleting files.
- Spreading: It can spread via email attachments, file-sharing networks, or removable storage devices (like USB drives) when users unknowingly share infected files.
Types of Viruses
- File Infector Viruses: Attach themselves to executable files.
- Macro Viruses: Target programs like Microsoft Word or Excel by using macros.
- Boot Sector Viruses: Infect the boot sector of storage devices, affecting the startup process.
Impact of Viruses
- Data Loss: Viruses can corrupt or erase vital data from a computer.
- System Performance: They can slow down system performance, making it difficult to operate.
- Security Breaches: Some viruses may steal personal information or create backdoors for further attacks.
In summary, a computer virus is a harmful software that not only replicates but also spreads, causing potential damage to systems and data. Understanding this concept is crucial for computer security and effective management of technology resources.
