Understanding RAM and ROM

The video tutorial explains the differences between RAM and ROM, two types of primary computer memory. It covers their definitions, physical forms, data storage capabilities, and access methods. RAM is volatile and allows data to be rewritten, while ROM is non-volatile and stores permanent data. The tutorial also discusses how increasing RAM and ROM speeds can affect computer performance.

What are the two main types of computer memory?

• Primary and Tertiary Memory

• Primary and Secondary Memory

• Volatile and Non-volatile Memory

• Internal and External Memory

Which type of memory is typically an optical drive made of magnetic tapes?

• RAM

• ROM

• Cache

• Flash Memory

How is data stored in RAM different from data stored in ROM?

• Data in RAM is permanent, while data in ROM is temporary.

• Data in RAM can be modified, while data in ROM is permanent.

• Data in RAM is read-only, while data in ROM can be rewritten.

• Data in RAM is stored on magnetic tapes, while data in ROM is on chips.

What must happen before the CPU can access data stored in ROM?

• The data must be transferred to RAM.

• The CPU must be restarted.

• The data must be decrypted.

• The ROM must be formatted.

What type of data does RAM store?

• Permanent data for bootstrapping

• Temporary data being processed by the CPU

• Data for long-term storage

• Data for external devices

What happens to the contents of RAM when the device is powered off?

• They are saved permanently.

• They are transferred to ROM.

• They are encrypted.

• They are lost.

Which type of memory retains its contents even when the device is powered off?

• Virtual Memory

• Cache

• ROM

• RAM

Which type of memory is volatile?

• ROM

• Hard Disk

• RAM

• Flash Memory

How does increasing the speed of RAM affect a PC?

• It has no effect on the CPU speed.

• It decreases the overall speed of the PC.

• It increases the CPU speed when running programs.

• It decreases the CPU speed.

What is the effect of increasing ROM speed on a PC?

• It increases the overall speed of the PC.

• It has no effect on the PC speed.

• It increases the speed of the CPU.

• It decreases the speed of the CPU.
