What is Hardware
Two basic components make up a computer: hardware and software. You simply can’t have
one without the other. All computer parts that you can physically see or touch are called
hardware. Hardware includes the computer’s monitor, case, keyboard, mouse, and printer.
What is software
Computer programs that tell hardware how to operate are called software. You may have
used software such as Microsoft Excel or Corel WordPerfect in the past. So breathe a giant
sigh of relief—you don’t have to know how to program a computer to use one. A computer
programmer has already done the work for you by writing the program (software). All you
have to do is tell the software what you’re trying to do, and the software then directs the
work of the hardware.

Part of the computer
Case or System Unit The main computer box, technically known as the system unit, is the most
important part of a computer. It contains the guts and brains of the computer—
something we’ll talk about later. The system unit contains a lot of holes or ports
where you plug in the rest of the computer system.
Monitor The monitor resembles a television set, and is where the computer displays
information.
Keyboard The keyboard is the thing you type on to tell your computer what to do.
Mouse Like the keyboard, the mouse is another input device that you use to
communicate with your computer.
Speakers Most computers can make sounds, just like a stereo system. In fact, you can
even listen to audio CD’s on most computers or watch DVDs.
Printer A printer is where a computer writes down information or output, onto paper, or
a hardcopy.
