A heat sink is a device used to dissipate heat generated by a processor or other electronic components. It is designed to absorb and transfer the heat away from the processor, helping to prevent overheating. By increasing the surface area exposed to the surrounding air, a heat sink allows for more efficient cooling through convection. This helps to maintain the optimal temperature for the processor to function properly and avoid damage caused by excessive heat.

3. Which of these is a computer virus? (please choose 2)

Man Flu

Trojan

Worm

Mad cow disease

A computer virus is a type of malicious software that can replicate itself and spread from one computer to another. Trojans and worms are both examples of computer viruses. Trojans are disguised as legitimate software and trick users into installing them, allowing unauthorized access to the computer. Worms, on the other hand, are self-replicating programs that can spread across networks without any user interaction. Therefore, both Trojans and worms are considered computer viruses.

Topology refers to the actual physical layout of a network. It describes how devices are connected and the arrangement of cables, routers, switches, and other networking components. Understanding the network topology is crucial for troubleshooting, planning, and optimizing network performance. It helps network administrators identify potential bottlenecks, points of failure, and areas for improvement. By analyzing the topology, administrators can determine the best configuration and design for their network to ensure efficient and reliable communication between devices.

7. How many USB devices can be connected to a USB port at one time?

63

127

1

4

2067

A USB port can support up to 127 devices connected at one time. This is because USB technology uses a hierarchical tree structure, where each device is assigned a unique address. The USB controller in the host device manages the communication between all connected devices. The USB specification allows for a maximum of 127 unique addresses, hence the maximum number of devices that can be connected to a USB port.
