Olympiad Test : Internet And Viruses - 1 Class 7 National Cyber MCQs

You cannot browse websites on the internet using FTP.

FTP (File Transfer Protocol) is a standard network protocol used to transfer files between a client and a server on a computer network. It is primarily used for uploading and downloading files, but it does not support browsing websites like a web browser does.

The other options mentioned - broadband, dial-up, and 3G/4G - are all methods of accessing the internet and can be used to browse websites. Here's a brief explanation of each:

• Broadband: This refers to high-speed internet connections that provide fast and reliable access to the internet. It can be delivered through various technologies such as DSL, cable, or fiber optic cables.


• Dial-up: This is a slower method of internet access that uses a telephone line and a modem to establish a connection. It is less common nowadays due to its slower speeds and limitations.


• 3G/4G: These are mobile network technologies that allow wireless internet access on mobile devices. 3G (third generation) and 4G (fourth generation) networks provide faster speeds and better connectivity compared to dial-up.

Therefore, the correct answer is D: FTP.

The correct answer is B: Blogging.

To effectively protect your computer system from viruses and malware, it is essential to use antivirus software. Antivirus software is specifically designed to detect, prevent, quarantine, and remove viruses and other malicious software. Here's why antivirus software is crucial:

Identification:

• Antivirus software scans your computer system and checks for any suspicious files or activities that might indicate the presence of a virus.


• It uses various detection methods, such as signature-based detection, heuristic analysis, and behavioral monitoring, to identify known and unknown viruses.

Prevention:

• Antivirus software provides real-time protection by monitoring your system and blocking any attempts by viruses to infect your files or compromise your privacy.


• It actively scans incoming files, downloads, and websites to prevent malware from getting into your system.

Quarantine:

• If a virus is detected, antivirus software can quarantine the infected file or isolate the malicious code to prevent it from spreading further.


• By quarantining the virus, the software ensures that it cannot harm your system or other files.

Removal:

• Antivirus software offers the capability to remove viruses from your system once they have been identified and quarantined.


• It can clean or delete the infected files, ensuring that your system is virus-free.

In conclusion, antivirus software is an essential tool for identifying, preventing, quarantining, and removing viruses. By regularly updating and using an antivirus program, you can significantly enhance the security of your computer system and protect your personal data.
