Byte: A group of 8 bits is called a byte.
Megabyte Conversion: One megabyte equals 1,000,000 bytes.
Device Drivers: Device drivers allow input/output devices to interact with the computer system.
Memory Types: The two main types of computer memory are primary and secondary.
CD-ROM: A CD is a non-erasable disk used for storing digitized audio.
Outputting Data: Outputting is the process of creating usable information for the user.
Plotters: Plotters produce images and drawings, both single color and multi-colored.
Drum Printers: Drum printers are line printers that print one line at a time.
CRT Monitors: CRT monitors, resembling televisions, are commonly used with non-portable computer systems.
Output Unit Function: The output unit does not supply data and instructions to the computer.
Bit: A bit is the smallest unit of data in a computer.
Input Unit Function: The input unit does not format data for human understanding.
