This document discusses basic computer hardware and software maintenance. It provides explanations of common hardware components like cases, drives, keyboards, mice, monitors, and printers. It also discusses basic software like programming software, operating systems, and applications. Specific examples of operating systems and applications are given. The document then defines window environments and provides examples of environment variables and how to set them up in Windows.

4. WINDOW ENVIRONMENT
DEFINITION
 Refers to computers running under a
Microsoft Windows operating system.
 Also called a "windowing environment," it
refers to any software that provides multiple
windows on screen such as
Windows, Mac, Motif and X Window. Also
may refer to an application that provides
multiple windows for documents or pictures.

5. WORKING IN THE WINDOW
ENVIRONMENT
 ENVIRONMENT:an area of memory
associated with the command
processor that provides up to 32KB of
space for storing variables,contain
information about the operating
environment that is used by the
operating system and other programs in
various ways.

6. EXAMPLES OF THE WINDOW
ENVIRONMENT
 ComSpec: specifies the location of the
command interpreter.
 PATH :specifies the locations to search for
commands typed at the command line.
 Prompt :specifies how the command
prompt should appear to the user.
 AGE :a user-defined variable for
indicating the age of something.
 TEMP :specifies the directories where
temporary files should be placed.

7. SETTING UP ENVIRONMENT
VARIABLES
1. From the start menu go to settings then control panel
2. Double click on the System icon, this will bring up a dialog box.
3. Click on the advanced tag and then environment variables, this will
bring up another dialog box with two scrollable windows, in Windows
2000 the top one is for local variables and the bottom for SYSTEM
variables, in Windows NT it is the other way round.
4. Find the environment variable named PATH and click on it. It should
be self-explanatory. To edit a variable, click on edit, to add a new
variable, click on new. The only SYSTEM variable we will edit is
PATH all the other environment variables we will edit will be LOCAL.
When I talk about appending to/adding to an environment variable I
mean editing it and sticking another file name on the end.
5. Windows uses the convention that environment variables are
separated by this character ";" If you are appending to a list of
directories make sure you add this character onto the end of the list
before you add your directory to the list. Do not add ";" after the last
file name in the list as this may cause problems, just make sure that
directory entries are separated by ";"'s.
