CMSC100 Lecture 1: Computers and You
So, there’s this thing in your house called a computer. Maybe you’ve heard of it, maybe not. But
do you want to know how to use it? Are you tired of being called “old” or stupid” just because
other people can use the internet but you don’t know how? If so, you’ve come to the right place.
But first things first. We need to get the basics out of the way.
Computer Basics
Turning on the computer:
1. Make sure the computer is plugged into its power source and sufficiently charged
2. Press the power button to turn on the computer
3. Profit?
Differences between laptops and Desktops
1. Laptops are smaller and more portable
2. Laptops have a touchpad which you can use instead of a mouse.
Using a Mouse
First of all, what is a mouse?
A mouse is the primary way to control a computer
A mouse usually has a left mouse button and a right mouse button
You need to put the mouse on a flat surface with the buttons facing the computer in
order to use it correctly.
You hold the mouse by resting your entire hand on top of it and putting your index finger
on the left mouse button. You rest your thumb on the side. If you’re like me, this means
your middle finger controls the right mouse button.
When you move the mouse, it moves a cursor on your screen. The cursor will change
shape depending on what the computer is doing. For instance, an hourglass is the
computer’s way of telling you that an operation is in progress and that you should wait.
An arrow means that you can select things and move them around.
A hand means you can lick on a link.
To select things, you click on them once with the mouse.
To open things, you double click on them twice in rapid succession.

To drag and drop things, you hold down the left mouse button, select the item you want
to drag and them move the cursor to where you want to drop it and release. The item
has now been successfully moved.
Desktop
What you’ll be greeted by once you turn the computer on is what is called the desktop.
This is what is called the homescreen of the computer. Files and programs live in the
desktop and you can open them from the desktop.
You can add shortcuts to access your files and programs even faster.
Icons represent files or programs. The folder icon looks like a folder and contains other
programs or files within it. The document icon represents a document and is usually
stand alone.
The start button lets you open up a menu where you can see all your files and programs.
The taskbar shows you all the programs or files you currently have open.
Folders
As previously stated, folders have files or programs within them. When you open a folder,
the content will appear in a new window.
You use the scrollbar to browse through the folder.
The titlebar displays the name of the folder, document or file in question.
The menubar is where you can see what you can do with the files in the folder.
The toolbar is where you will find many of the shortcuts for actions in the menubar.
Windows
You can have many windows open at the same time.
The current window has a highlighted title bar and appears first on the task bar.
The open windows are displayed as buttons on the task bar.
You can switch between windows by clicking on the window or clicking on the button in
the task bar.
