Computer Hardware Quiz: Unit 1

What is the primary function of the Central Processing Unit (CPU) in a computer system?

• To store long-term memory even when the computer is off.

• To hold all other pieces of the computer together and allow them to communicate.

• To run programs and solve computations, acting as the brain of the computer.

• To expand the capabilities of your computer, such as displaying graphics.

A processor has 8 physical cores and uses multi-threading to achieve 16 threads. How many actual cores does this processor have?

• 16, because threads act as additional cores.

• 8, as threads are a way to 'trick' the operating system into thinking there are more cores than there actually are.

• 24, combining cores and threads.

• It depends on the clock speed.

What is the clock speed of a CPU measured in, and how many cycles per second does 3 Gigahertz (GHz) represent?

• Megahertz (MHz); 3 million cycles per second.

• Gigahertz (GHz); 3 billion cycles per second.

• Cycles Per Second (CPS); 3 billion cycles per second.

• Terahertz (THz); 3 trillion cycles per second [No information in sources].

Which type of memory is described as 'short term memory on the computer' where anything stored is lost when there is no power?

• Hard Disk Drive (HDD).

• Solid State Drive (SSD).

• Random Access Memory (RAM).

• L3 (level 3) cache.

Which of the following statements accurately compares Solid State Drives (SSDs) and Hard Disk Drives (HDDs)?

• HDDs are typically 20 times faster than SSDs in accessing data.

• SSDs are drastically more expensive per gigabyte than HDDs.

• HDDs make no noise, while SSDs produce significant mechanical sounds.

• SSDs need to be defragmented regularly to maintain speed, unlike HDDs.

What is the role of the motherboard in a computer system?

• It is the short-term memory that loses data when power is off.

• It is the brain of the computer where programs run and computations are solved.

• It holds all other computer pieces together and enables them to communicate with each other.

• It is a type of expansion card that allows for faster storage.

Which of the following is an example of an ?

• Keyboard.

• Mouse.

• Monitor.

• Mic.
