         Session 1:
    Computer Science Stuff
   and CADGIS Introduction
Operating Systems
What is an operating system?
4 An operating system is a set of programs
  that manages the resources of a computer
  system. (Resources include memory, disk
  space, peripherals, CPU, etc.)

4 The operating system is both rule-maker
  and referee.
Examples of operating systems
4 Windows (variants)
4 Unix (variants)
4 Linux
4 Mac OS X
4 and others….
What is a user interface?
4 A user interface is the mechanism by which
  a user of a computer system can
  communicate with its operating system and
  application programs
User interfaces
4 Some user interfaces are graphical by
  nature. These interfaces are Graphic User
  Interfaces or GUI (pronounced goo-ee).
  They will use pictures and symbols for
  users to point and click.
4 Other user interfaces use text. When the
  text is entered on lines in a typewriter
  fashion, the user interface is called a
  command line interface.
Examples of Command Line
4 DOS batch commands
4 Unix K-shell and C-shell
Examples of Graphics User
4 Windows
4 MacOS Finder
4 X-Windows
4 Windows 3.x was a graphic user interface
  for DOS. It needed DOS to operate and
  could not operate on its own.
4 Windows 7, Vista, XP, 2003, 2000, NT,
  ME, 98, and 95 ARE operating systems in
  their own right. They do not need DOS at
4 The term Windows can now refer to an
  operating system or user interface.
Windows 7
4 For this semester, the operating system will
  be Windows 7.
4 The servers of CADGIS use Windows
  Server 2008 and 2003
Using Windows XP
Logging into Windows 7
4 Login by press Ctrl+Alt+Del keys
4 Enter your username of PAWS ID
4 Enter your password of PAWS password
4 The domain should be LSU
The Desktop
4 Task bar with the Start Button
4 Icons (short cuts to programs and/or files)
4 Background
4 The Recycle Bin
The Task Bar
4 Shows programs already running
The Start Button
4 Gives access to programs and settings
4 Appears on one end of the task bar
The Mouse
4 A single click of the left button on an icon
  selects the icon for some action.
4 Double clicking the left button on an icon
  causes the icon to perform its default action.
4 A single click of the right button on an icon
  displays a list of actions that may be applied
  to the icon.
The Recycle Bin
4 Files that are deleted are not removed from
  the disk but are moved to the recycle bin
4 Files in the recycle bin can be restored to
  their original place on the disk or moved to
  a new place
4 The recycle bin can be emptied to make
  space available on a disk. At that point, the
  files in the recycle are GONE FOREVER!
My Computer
4 Allows you to see resources such as disk
  drives on your machine.
The Network Neighborhood
4 Allows you to see all machines in your
4 Allows you to see other domains.
4 Control Panels
4 Printers
4 Task Bar
4 Allows a user to add or remove a printer
  from the local machine
4 Allows a user to view the status of the
  printers such as the queue for use.
4 Allows a user to select a default printer for
Control Panel
4 Allows you to access the many features of
  Windows that control how it and your
  computer operates.
4 Only users with administrator privileges are
  allowed to change settings within the
  control panel.
CADGIS Printers
4 Papyrus1 is the server for the 36” plotters
4 Papyrus2 is the server for the sheet fed
4 CADGIS has 24 hour printing also
4 Check the CADGIS web site at
  for plotting prices
CADGIS Printers
4 Color 36 on Papyrus1
   – large format color plotter
4 Color 08x11 and Color 11x17 on Papyrus2
   – small format color
4 bw 08x11 on Papyrus2
   – small format black and white
4 bw 36 on Papyrus1
   – large format black and white
Windows Explorer
4 The “File Manager” of Windows
4 Allows users to copy, delete, move, and
  rename files.
4 Allows users to create directories.
4 Allows for the mapping of disk drives.
4 Allows a user to search for files bases on
  name, date, etc.
Filenames on Windows
4 The names of files and directories on Windows
  can have as many as 128 characters.
4 The characters that are allowed in the names are
  letters (both upper and lower cases), digits, dashes,
  underscores, and even blanks.
4 While upper and lower case letters are allowed,
  file names are case insensitive.
Filenames (cont.)
4 Windows still uses file suffixes to designate
  the kind of file.
4 Suffixes are formed by a period (.) followed
  generally by three characters. For example,
  x.doc is a Word document file.
Copying and Moving of Files
4 Explorer uses the copy and paste
  mechanisms to make copies of files.
4 Explorer uses the cut and paste mechanisms
  to move files between directories.
Deleting Files
4 Deleted files are not removed but are moved
  to the recycle bin.
4 Files can be retrieved from the recycle bin
  as long as the recycle bin has not been
4 Files can be moved from the recycle bin to
  directories other than their original
Finding Files
4 Files can be found by name, creation date,
  or even by size
4 Directories and their subdirectories can be
4 All directories on all drives of a computer
  can be searched.
Mapping Network Drives
4 Drives on other machines can be mounted
  or mapped as though they were located on
  your machine.
4 Important Drive Letters
  W: Homework directory
  X: CADGIS data directory
  Y: CADGIS Classinfo directory
  Z: user’s folder on CADGISuser
Important Directories
Program Directories
4 Applications and programs are found one of
  two directories
  – C:\Program Files
  – C:\WIN32APP (obsolete)
4 The operating system can be found in
\Temp Directory
4 The temp directory is a place for temporary
  files to be stored.
4 Programs will create temporary files in this
4 Users can also create files in \TEMP
4 DO NOT STORE anything of importance in
  the \TEMP directory, for files there can be
  deleted at any time.
The CADGISusers directory
4 Each student user has a folder under
  \\\cadgis\users. The name of this directory
  is the same as the user’s login which is the user’s
  PAWS account.
4 The combined size of all the files for your
  CADGIS users folder is limited to 250MB.
The CADGISusers directory
4 Windows will not allow your to store over
  your quota of 250MB. If you attempt to do
  so, you will get a “Drive Full” error
The CADGISclassinfo directory
4 Most classes that use the CADGIS Lab have a
  class folder under \\\cadgis\classinfo.
4 The computers in the CADGIS Lab will map the
  Y: drive to the Classinfo directory.
4 Students can read files in this directory and can
  copy files from this directory.
4 Student CAN NOT WRITE files to this directory
  and CAN NOT MODIFY files in this directory.
The CADGISdata directory
4 Much of the spatial data of the CADGIS Lab have
    a class folder under \\\cadgis\data.
4   The computers in the CADGIS Lab will map the
    X: drive to the data directory.
4   Students can read files in this directory and can
    copy files from this directory.
4   Student CAN NOT WRITE files to this directory
    and CAN NOT MODIFY files in this directory.
4   Much of this data is the same as can be
    downloaded from Atlas at
The Root Directory
4 Each drive has a root directory indicated by
  a single, solitary backslash (\) such as C:\
4 DO NOT STORE any file directly under the
  root director of drives in the CADGIS Lab.
  These files WILL BE DELETED.
DOS commands
4 A single DOS command can be entered
  from the Run option under the Start Button
4 Multiple DOS commands can be entered
  using the Run option and typing “cmd” as
  the command.
Logging out
4 Press CTRL+ALT+DEL to logout or go to
  the Shutdown option under the Start Button
4 Logging out will stop all programs.
4 It is possible to “lock” a workstation so that
  programs continue to operate while no other
  user is allowed to use the workstation. DO
  NOT LOCK CADGIS workstations!
