Computer Memory Quiz

What role does memory play in both humans and computers?

• It assists in remembering past events, learning skills, and planning for the future.

• It helps in processing emotions.

• It is responsible for generating power.

• It is used for physical activities.

What are the basic units of memory in a computer called?

• Transistors

• Cells

• Bits

• Bytes

What is the primary function of short-term memory in computers?

• Storing data permanently

• Performing immediate tasks

• Generating power

• Connecting to the internet

Why is RAM referred to as 'random access' memory?

• Because it is randomly generated

• Because it is used randomly

• Because it can be accessed in any order

• Because it can only be accessed sequentially

What is the main difference between DRAM and SRAM?

• SRAM is faster but more expensive than DRAM

• SRAM requires periodic recharging

• DRAM is faster but more expensive than SRAM

• DRAM is used for long-term storage

Which type of long-term storage uses a magnetic pattern on a spinning disc?

• Optical storage

• Solid-state drives

• Magnetic storage

• Flash sticks

What is a key characteristic of optical storage media like DVDs and Blu-rays?

• They are cheap and removable but have slower latencies

• They have high capacity and fast access times

• They are the most expensive type of storage

• They use magnetic patterns to store data

What is a major advantage of solid-state drives over other types of long-term storage?

• They have no moving parts and use floating gate transistors

• They are the slowest type of storage

• They use magnetic patterns

• They have moving parts

What is a common issue with the reliability of computer memory?

• It degrades quickly due to heat and environmental factors

• It improves over time

• It never degrades

• It is always stable and permanent

What are scientists working on to improve memory devices?

• Eliminating the need for power in RAM
