Question 4 of 625

A technician is tasked with installing additional RAM in a desktop computer. Which of the following types of RAM is MOST likely to be used?

SODIMM

DDR3

ECC

VRAM

Correct Answer: B

DDR3 (Double Data Rate 3) is a type of RAM commonly used in desktop computers. It is the third generation of DDR memory, and it has been widely used in various desktop systems. SODIMM (Small Outline Dual Inline Memory Module) is primarily used in laptops and other compact devices. ECC (Error Correcting Code) RAM is mainly used in servers and high-end workstations to prevent data corruption. VRAM (Video Random Access Memory) is used in graphics cards. Thus, DDR3 is the most appropriate type of RAM for a desktop computer.

Question 5 of 625

Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?

Roller

Drum

Transfer belt

Ribbon

Correct Answer: B

Vertical streaks on the output of a laser printer are most commonly caused by a problem with the printer's drum. The drum is a crucial component that transfers toner from the cartridge onto the paper. If it becomes damaged or worn out, it can cause toner to be improperly applied, leading to vertical streaks on printed output. Therefore, the drum is the most likely culprit in this scenario.
