6. PART 1: Peripherals
Peripherals are input and output hardware devices which
plug into the computer.
Cable plugs and slots have unique shapes and colors
(sometimes) to ensure proper connection.
Take a minute to look at the back of your computer and
examine the different connections.
Proper connectivity is key to the successful operation of the
computer system. If you are having computer problems, a
good rule of thumb is to shut down the computer and check
all the cable connections to see if they are properly secured.

7. PART 1: Operating System
What is an Operating System?
An operating system (OS) is a software program that controls and
runs just about everything on your computer. Windows (98, 2000, XP)
are all examples of different versions of the Windows Operating
System. The Windows OS has three main parts: Desktop, Taskbar
and Start Button.
Like a conductor or a coach -- an OS is an ‘invisible’ intermediary who
makes sure that all the different components (hardware and software)
work smoothly together. Although there are many different kinds of
operating systems, Windows is most commonly used on PCs.
What makes Windows special?
Windows makes computers easier to use because it employs a GUI
(“gooey”) or Graphical User Interface. Instead of requiring users to
remember specific commands, GUIs represent different tasks and
functions with pictures. Now all a user needs to do is “point and click”.

8. PART 1: Starting Your Computer
REMEMBER: A computer is a sensitive electronic machine. Turn it on and
off properly to ensure that you don’t damage the hardware or lose any data.
1. Make sure your computer is plugged in (if the computer is plugged into a
power strip, be sure that the power strip is plugged in and the switch is in the “ON”
position).
2. Press the POWER button on your CPU
3. Press the POWER button on your monitor
4. You will usually see a black screen with letters running across it. This is normal
-- it is just the computer going through the “power up” process and automatically
checking its systems
5. You should see a blue screen with Windows on it soon.
On some computers, like the ones in this CORE class, you may be prompted for
information. A box will appear on your screen asking you to “Log on to the
Network.” This is where you need to enter a USERNAME and PASSWORD,
which was assigned to you at the beginning of class. Try it out!

9. PART 1: Maintenance Tips
1. Don’t have food or drink around the computer
(or at least don’t spill it!).
2. Don’t put anything other than the correct items
into the slots and openings of the computer.
3. Don’t plug or unplug anything without turning
the computer off first.

10. PART 1: Clicking Together -- Using the Mouse
The Mouse: Practice, Practice, Practice!
1. Allows you to move freely around screen
2. Allows you to “point” and “click” (select) items
3. Cursor: The point (usually an arrow) used to represent the
mouse’s position
4. Left button: Main button used
Right button: Context specific
5. Click: Pressing a button
a) Single click – pressing once
