What is “ROM” in computer hardware?
a) Read-Only Memory
b) Random Operating Module
c) Remote Operating Machine
d) Rapid Output Memory
Answer:
a) Read-Only Memory
Explanation:
ROM stands for Read-Only Memory. It is a type of non-volatile memory used in computers and other electronic devices to store data that is permanently written and cannot be modified or deleted by the user.
ROM is typically used to store firmware, which is essential for booting up the computer and performing basic tasks. Unlike RAM, ROM retains its data even when the computer is turned off, making it ideal for storing instructions that need to persist.
ROM is important because it holds the startup instructions for the computer, such as the BIOS (Basic Input/Output System), which initializes the system hardware and loads the operating system.
