Which laptop component makes use of throttling to reduce power consumption and heat?
- A.
CPU
- B.
Motherboard
- C.
Optical drive
- D.
Hard drive
Correct Answer
A. CPUExplanation
The CPU (Central Processing Unit) is the component of a laptop that makes use of throttling to reduce power consumption and heat. Throttling is a technique used to decrease the performance of the CPU temporarily in order to prevent it from overheating or consuming excessive power. By reducing the clock speed or voltage of the CPU, throttling helps to maintain a balance between performance and heat/power management, thus ensuring the proper functioning and longevity of the laptop.Rate this question:

Why are SODIMMs well suited for laptops?
- A.
They have a small form factor.
- B.
They connect to external ports.
- C.
They do not produce heat.
- D.
They are interchangeable with desktops.
Correct Answer
A. They have a small form factor.Explanation
SODIMMs (Small Outline Dual Inline Memory Modules) are well suited for laptops because they have a small form factor. This means that they are physically smaller than regular DIMMs (Dual Inline Memory Modules) used in desktop computers. The smaller size of SODIMMs allows them to fit into the limited space available in laptops, making them a suitable choice for these portable devices.Rate this question:

A technician is trying to remove a SODIMM module from a laptop. What is the correct way to do this?
- A.
Pull outward by holding the center of the SODIMM module.
- B.
Apply downward force on the SODIMM module.
- C.
Desolder the SODIMM module.
- D.
