Understanding Computer Memory

What is the basic unit of memory in computers called?

• Bytes

• Bits

• Cells

• Transistors

Which part of the computer acts as its brain?

• Memory

• Hard Drive

• Central Processing Unit (CPU)

• Random Access Memory (RAM)

What type of memory is used for immediate tasks in a computer?

• Long-Term Memory

• Static RAM

• Short-term Memory

• Optical Memory

What is the main characteristic of Dynamic RAM (DRAM)?

• It holds data permanently.

• It requires periodic refreshing to retain data.

• It does not need refreshing.

• It is the fastest type of memory.

What type of storage is considered the cheapest?

• Solid-state drives

• Optical storage

• Magnetic storage

• Random Access Memory

How does optical storage read data?
