WHAT IS AN OPERATING SYSTEM?
 What is an operating system?
 Operating system is a software program.
 Must load Windows OS into RAM
prior to using any software programs.
 OS is in charge of hardware
components of computer.
 User communicates with OS.
 OS runs the system.
 Manages input/output of computer.
 Manages computer resources.
 Runs application software.

 OS – software program that makes
computer work.
 Commands - instructions OS understands
--Like verbs i.e. COPY or PRINT.
 Wintel machines.

If students have not installed or upgraded
to Windows XP Professional on personal
computer refer them to documentation
that came with Windows software so they
can initiate installation or upgrade.

SECTION 1.3 (pp. 3-4)
 Slides 15-17
 Lose everything when computer turned off.
 A file is a set of related information stored
on disk in “file folder with a unique name.
FILE NAMES, FILE TYPES, AND FOLDERS
 File Names, File Types, and Folders
 File name (technically file specification).
 Must have a unique name.
 Comes in two parts.
 File name.
 Mandatory.
 Describes/identifies contents of
file.
 Prior, W used (DOS) 8.3 rule.
 Now, file names can be maximum
of 255 characters (LFN’s).
- Three letter extension (file type)
remains.
 Consider using 8.3 rule.
 Some software/network OS
does not recognize or have
problems with long file names.
 Storing long file names takes
up space.
 File extension.
 Not mandatory.
 Identifies type of file.
 Tells what kind of data is in file.
 .EXE stands for executable code.


 Command line interface.
 Need to know command & how to use it.
Why learn DOS?
 Many tasks cannot be done from GUI.
 Windows utility programs only run at
command line help to solve problems
with Windows.
 Other tasks accomplished easier/faster
from command line prompt.
 Assumption that user “knows” DOS.
 Error messages couched in DOS
terms.
 Some programs only run from DOS
system level.
 Internet users use command line that is
similar to DOS.
 Work with networks or career in network
administration – rely on command line
interfaces.
 Career in computer-related field – must
know command line interface.
 W XP has expanded list of commands
available at command line.
 W OS – write batch files – written, tested
and run at command line interface.
 XP has more powerful commands
available than in W ME and W98.
 Knowing DOS a must if working for A+
Certification.
ACCESSING THE COMMAND LINE PROMPT
 Accessing the Command Line Prompt
 To use command line interface must open
DOS window.
 Open DOS from menu or create shortcut.
 Do not turn off computer when in DOS
window.
 Exit DOS Window.
