ROM is an example of

Correct option is C

ROM (Read-Only Memory) is a type of non-volatile memory that retains its data even when the computer is powered off. It is used to store firmware or essential instructions that are permanently programmed and cannot be easily modified.

Important Key Points:

1. Non-Volatile Memory:
• Definition: Non-volatile memory retains stored data even after the power supply is turned off.
• ROM: Stores essential boot-up instructions (firmware) required to start the computer.
2. Types of ROM:
• PROM (Programmable ROM): Can be programmed once.
• EPROM (Erasable PROM): Can be erased using UV light and reprogrammed.
• EEPROM (Electrically Erasable PROM): Can be erased and reprogrammed electrically.

Knowledge Booster:

1. Volatile Memory: Volatile memory, like RAM, loses data when the power is turned off.
2. Fast Memory: While ROM is fast for reading data, it is not as fast as cache or RAM, which are considered fast memories.
3. Outdated Memory: ROM is not outdated; it is still used in modern devices for booting and firmware storage.
