ICT - Information Communication Technology Computer Hardware and Peripherals Questions and Answers

Question 1

A technician is upgrading a computer's storage. They want the fastest possible data access speeds for the operating system and frequently used applications. Which of the following storage types would be the BEST choice?

Accepted Answer

Solid State Drive (SSD)

Answer

Solid State Drives (SSDs) use flash memory to store data, offering significantly faster read and write speeds compared to traditional Hard Disk Drives (HDDs) which use spinning magnetic platters. Blu-ray and DVD are optical storage formats primarily used for media and software distribution, not for primary OS installation due to their slow speeds.

Question 2

A user reports that their new wireless mouse is not working. The mouse is powered on, and the correct software is installed. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The USB receiver is not properly plugged into the computer.

Answer

For a wireless mouse to function, its USB receiver must be securely connected to a USB port on the computer to establish a communication link. The monitor resolution, power supply health (if the computer is on), and keyboard connection are unrelated to the functionality of a wireless mouse.

Question 3

Which internal computer component is often referred to as the 'brain' of the computer, as it performs most of the processing?

Accepted Answer

Central Processing Unit (CPU)

Answer

The Central Processing Unit (CPU) is responsible for executing instructions and performing the calculations necessary for the computer to function. The Motherboard connects all components, RAM is for temporary data storage, and the PSU supplies power.

Question 4

A user is trying to connect their computer to the local office network using a physical cable. Which type of port on the computer would they most likely use?

Accepted Answer

Ethernet (RJ-45)

Answer

An Ethernet port, which accepts an RJ-45 connector, is the standard for wired network connections to a local area network (LAN). HDMI and VGA are used for video output, and USB is a general-purpose port for various peripherals.

Question 5

Which of the following is an example of volatile memory, meaning its contents are lost when the computer powers off?

Accepted Answer

Random Access Memory (RAM)

Answer

Random Access Memory (RAM) is a type of volatile memory that stores data the computer is actively using. When the power is turned off, the data in RAM is lost. SSDs, HDDs, and ROM are non-volatile storage, retaining data without power.
