You are a computer technician and someone has asked you to install a network with good redundancy what topology would you use.
- A.
Mesh
- B.
FDDI
- C.
Bus
- D.
Star
Correct Answer
A. MeshExplanation
A mesh topology would be the best choice for installing a network with good redundancy. In a mesh topology, each device is connected to every other device, creating multiple paths for data to travel. This ensures that if one connection fails, there are alternative paths available, minimizing the chances of network downtime. This redundancy feature makes mesh topology highly reliable and suitable for critical systems where uninterrupted connectivity is essential.Rate this question:

What is it called when some one fiddles with a cpu to work faster.
- A.
Throttaling
- B.
Hyperthreading
- C.
Clocking
- D.
Muzzling
Correct Answer
C. ClockingExplanation
Clocking refers to the process of manipulating the clock speed of a CPU to make it work faster. By increasing the clock speed, the CPU can process instructions at a higher rate, resulting in improved performance. This can be achieved through various methods such as adjusting the multiplier or front-side bus speed. However, it is important to note that overclocking can also lead to increased heat generation and potential instability if not done properly.Rate this question:

What state is the laptop in when its power state is S3
- A.
Save to RAM
- B.
Everything on but LCD light is dimmed
- C.
Hibernation
- D.
Off
Correct Answer
A. Save to RAMExplanation
When the power state of a laptop is S3, it is in the "Save to RAM" state. In this state, the laptop's current state is saved to the RAM (Random Access Memory) before the system enters a low-power mode. This allows the laptop to quickly resume its previous state when the power is restored. The other options, such as "Everything on but LCD light is dimmed," "Hibernation," and "Off," do not accurately describe the S3 power state.Rate this question:
