ROM: Read-Only Memory (ROM) is non-writable memory.
Byte: A combination of 8 bits is a byte.
Megabyte: A megabyte is equal to 1,000,000 bytes.
Device Drivers: Device drivers facilitate communication between devices and the computer system.
Memory Types: Primary and secondary memory are the two basic memory types in computers.
CD: A CD is a non-erasable optical disk for audio storage.
Outputting: Outputting is the process of producing user-friendly information.
Plotters: Plotters are used for producing images and drawings.
Drum Printers: Drum printers are line printers that print one line at a time.
CRT Monitor: CRT monitors are traditional monitors, typically used with non-portable computers.
Output Unit Function: The output unit's role is to present processed data, not to feed input to the computer.
Bit: The smallest unit of data in a computer is a bit.
Input Unit Function: The input unit receives data, it doesn't transform it into a user-friendly format.
