Hardware
- Printer, Scanner, and Monitor are examples of hardware.
- Interpreter is not an example of hardware.
Programming Languages
- Machine language is a computer language that is written in binary codes only.
- A Source Program is the program written by the programmer in high-level language.
- An Assembler is used as a translator for low-level language.
Flowcharts
- A diamond-shaped box in a flowchart is used to denote a decision.
System Development
- SDLC stands for Software Development Life Cycle.
Computer Types
