A. A Physical barrier to protect computers from heat.

B. A Combination of hardware and software that protects a network from unauthorized access.

C. A tool used to delete files permanently

D. A system designed to increase the speed of the CPU ?

Answer : A combination of hardware and software that protects a network from unauthorized access.

Details : A Firewall is a security system composed of both hardware and software. It’s primary role is to protect a computer or network from unauthorized access based on a set of rules though it does not literally protect hardware from fire.

Question No. 10. Which high- speed memory has the fastest access time computer ?

A. Cache Memory

B. RAM

C. ROM

D. Secondary Memory

Answer: Cache Memory

Details : Cache memory is a high- speed memory that enables computers to retrieve frequently used data in the shortest possible time. It sits between the CPU and the main memory, thereby reducing data access details and improving overall system performance. Moreover, Cache memory automatically stores commonly accessed instructions, allowing the processor to execute takes more efficiently . In constrast, ROM permanently stores essential startup instructions , while secondary memory, such as hard disk drive (HODs) and solid drives (SSDs), Provides long-term data storage. Therefore, such as hard disk drives( HDDs) memory for speed, making it the fastest memory available for data retrieval.

Question No. 11.In which network topology do the connected components form a closed loop ?

A. Tree Topology

B. Star Topology

C. Ring Topology

D. Bus Topology

Answer: Ring Topology

Details : Devices connect to one another in a closed loop, creating a circular network structure. Each device communicates with its neighboring devices, and data travels around the ring until it reaches its destination. Moreover, this topology provides organised data transmission. However , if one connection fails, it can disrupt communication across the entire network.

Question No.12 . A Computer monitor is also commonly referred to by which of the following names ?

A. LED

B. VDU

C. CPU
