Windows: The Concept
by
Andy Rush
Note!:
This document deals with the computer interface
and the concept of a "windowing" environment.
We are not referring to the Microsoft product,
and therefore the information in this document
will apply to all computers using a G.U.I.
| What's
a G.U.I. ?
The GUI
(the acronym GUI is sometimes treated
like a word, and is pronounced "gooey"),
which stands for Graphical User
Interface, is what you interact
with to make your computer do stuff. Let's
break it down. An Interface
is something that gives control
of a device. The steering wheel,
pedals, shifter, and dashboard are the
interface to a car. You have a keypad
on your phone and a remote for your television
which are interfaces to those devices.
A User, well, that's
You. Graphical
means with pictures.
So we put it all together and we have
You getting control of a device
with pictures. In this case our
device is a computer. |
The Computer
OK, so what do you know
about computers? Answers that people give to
this question generally fit on a continuum.
They range from "I know nothing about computers
and I'm afraid of them" to "I've worked
with many different platforms and have written
programs for several of them". You probably
fit somewhere in between. We talk in another
section about computer hardware,
but I want to briefly mention that there are
many different types of computers. You may or
may not be using the same type that I am creating
this document with. I happen to be using a Dell
computer running Windows XP. Dell is a brand
of computer and Windows is a platform.
Dell computers fall into the category of what
used to be known as an IBM compatible
or PC compatible. It is now
more commonly known as a Wintel
machine, meaning that it uses Microsoft Windows
for it's operating system (OS), and an Intel
corporation chip for its brains (CPU). Macintosh
is a brand and is also a platform (the Mac
OS). See the table below for some other
brands and platforms. To add a little further
confusion, some brands can run on different
platforms and vice versa.

I Don't Do Windows
So, do you do Windows?
Chances are you do. Whether you own a Dell or
a Gateway or even a Macintosh, you probably
use a GUI that is a windowing environment.
The windowing concept is one of getting a "view"
of a portion of your computer through a "window".
In the GUI, small pictures on the screen (called
icons) represent elements of the computer's
functionality. Many GUI's use the office environment
as the analogy. In an office you have a desk,
and a file cabinet, and a trash can and/or recycle
bin, etc. Well the same goes for the GUI on
your computer. You have a desktop
(see the examples of the Windows and Macintosh
desktops below), a Trash Can
(Macintosh) or Recycle Bin
(Windows 95/98/2000/XP), and electronic
file cabinets (your computer's hard
disk). The desktop is where
you do your work such as, write your letters
(word processors), create presentations
(programs like PowerPoint),
create artwork (photo editors like Photoshop),
keep track of addresses or recipes (databases),
and so on. The electronic file cabinet
is the place where you store all of your work.
The Trash Can or Recycle
Bin is obviously where you throw things
out you don't need.

OK, So I Do Windows. What Are They Again?
Well, let's start with
what they aren't. In the old days of computer
interfaces, you had to type on a keyboard the
commands to get the computer to do something.
If you wanted to list some files in a particular
section of the computer (a directory) you typed
a command. If you wanted to start a program,
you typed a command. If you wanted to get rid
of a document or file, you typed a command.
MS-DOS and some Unix
systems still work this way, but unless you're
a programmer, the windows style environment
is much preferred. In the windowing environment,
to see a list of files you would point your
mouse at an icon and click. To start a program
click an icon. To get rid of something move
the icon of the file over the trash can/recycle
bin and let go.
The window is your
view of a section of the computer. Within the
window will be one or more icons representing
programs, files, documents or folder icons where
more icons will be contained within. You can
have multiple windows open on the desktop by
clicking either drive icons or folder icons.
When we say clicking icons, we are actually
talking about a procedure called double-clicking,
which is two rapid clicks of the mouse button
on the icon.

If you look at the Windows
desktop, you'll see an icon labeled My
Computer. Opening this icon will display
the My Computer Window. Within this window are
the different icons representing the drives.
There is, for instance, an icon labeled 3½
Floppy (A:). This represents the floppy
disk drive. Another icon is labeled simply (C:).
This icon represents the internal hard
disk of the computer. There are other
icons representing other types of drives and
devices for the computer.
If you look at the Macintosh
desktop, You'll see an icon labeled MAC
HD 8.5. Opening this icon will display
the contents of the Macintosh hard drive window.
Within this window are the folders that contain
programs, files and documents on the hard disk
of the computer. Macintosh computers differ
from the Windows computers in that the drives
appear directly on the desktop when you insert
the media, be it a floppy or Zip disk, or CD-ROM.
We talk more about hard drives and other computer
stuff in the hardware
section.
