Hardware and Software
Classify computer components as hardware or software.
A computer needs both physical parts and programs to work.
- Define hardware and software.
- Name internal and external hardware.
- Distinguish system software from application software.
Hardware
Hardware is the physical equipment you can touch:
- Input devices — keyboard, mouse, scanner, microphone.
- Processing — CPU (central processing unit).
- Output devices — monitor, printer, speaker.
- Storage — hard disk, flash drive, memory card.
Software
Software is the set of instructions that tells hardware what to do. System software includes the operating system and utilities. Application software performs user tasks: word processors, browsers, games and spreadsheets.
They Need Each Other
Hardware without software is like a car without fuel. Software without hardware has nowhere to run.
A printer — hardware (output).
Microsoft Word — application software.
Windows — system software.
A flash drive — hardware (storage).
Practice
- Define hardware and software.
- Classify: monitor, web browser, CPU, operating system.
- Give one example each of system and application software.
Recap
Hardware is physical; software is instruction. System software runs the machine and application software does user tasks.
