Answer 2

Answer:

Read-only memory, or ROM, is computer memory containing data that can only be read, not written to. ROM contains boot-up programming that is used each time a computer is turned on. It generally can't be altered or reprogrammed.

Explanation:

Usage

• RAM allows the computer to read data quickly to run applications.
• ROM stores all the application which is needed to boot the computer initially. It only allows for reading.

Volatility

• RAM is volatile. So, its contents are lost when the device is powered off.
• ROM is non-volatile, i.e., its contents are retained even if the device is powered off

Accessibility

• Information stored in the RAM is easily accessed.
• The processor can’t directly access the information that is stored in the ROM. In order to access ROM information first, the information is transferred into the RAM, and then it can be executed by the processor.

Read/Write

• Both R (read) and W (write) operations can be performed over the information which is stored in the RAM.
• The ROM memory allows the user to read the information. But, the user can’t alter the information.

Storage

• RAM is used to store temporary information.
• ROM memory is used to store permanent information, which is non-erasable.

Speed

• The access speed of RAM is faster.
• Its speed is slower in comparison with RAM. Therefore, ROM can’t boost up the processor speed.

Cost

• The price of RAM is quite high.
• The price of ROM is comparatively low.

Chip size

• Physical size of RAM chip is bigger than ROM chip.
• Physical size of ROM chip is smaller than the RAM chip of same storage capacity.

Preservation of Data

• Electricity is needed in RAM to flow and to preserve information Electricity is not required to flow and preserving information

Structure

• The RAM chip is in rectangle form and is inserted over the motherboard of the computer.
• Read-only memory (ROM) is a type of storage medium that permanently stores data on personal computers (PCs) and other electronic devices.
