- (a) Translate high-level programming language code into machine code that the computer can understand
- (b) Run software applications
- (c) Manage files and folders
- (d) Connect to a network
Explanation: A compiler reads high-level programming language code and translates it into machine code, which the computer’s processor can directly understand and execute.
10)Which type of software protects against malware and viruses?
- (a) Antivirus Software
- (b) Word Processing Software
- (c) Database Management Software
- (d) Operating System
Explanation: Antivirus software specifically detects and protects against malware, viruses, and other malicious software threats. While operating systems may have some built-in security features, dedicated antivirus software offers more comprehensive protection.

- (a) IP Address (Internet Protocol Address)
- (b) DNS Name (Domain Name System)
- (c) URL (Uniform Resource Locator)
- (d) Hostname
Explanation: An IP address is a unique numerical identifier assigned
12)What is the primary purpose of a firewall?
- (a) Monitor and control access to a network, blocking unauthorized traffic
- (b) Connect devices wirelessly
- (c) Share files and resources
- (d) Encrypt data
Explanation: Firewalls act as security barriers, monitoring and controlling incoming and outgoing network traffic to block unauthorized access and potential threats.
13)What does the acronym “VPN” stand for?
- (a) Virtual Private Network
- (b) Very Powerful Network
- (c) Voice over IP Network
- (d) Virtualized Public Network
Explanation: VPN stands for Virtual Private Network. It creates a secure tunnel for data transmission over a public network, encrypting data and shielding it from unauthorized access.
14)What is the process of “booting” a computer?
- (a) Initializing the hardware and software necessary to start the system, loading the operating system and basic drivers
- (b) Shutting down the computer and closing running applications
- (c) Updating the operating system with the latest security patches
- (d) Installing new software applications on the system
Explanation: Booting is the process of starting a computer system. It involves initializing hardware components, loading the operating system kernel and essential drivers, and configuring the system for basic functionality.
