Specific Learning Objectives

• Identify and define the terms associated with system management

• Identify critical system files used by operating systems

• Add/remove software and Windows components

• Install a Printer• Use Task Manager to end unresponsive

programs and view CPU/memory usage

4MCT260-Operating Systems I

Specific Learning Objectives

• Use Windows Internet Update Feature and Device Manager

• Restore your computer

• Modify system variables such as date and time

• Use CLI commands such as SET, DATE, TIME, VER, and MEM

Critical System Files

• As OS’s have evolved, so has the way they store configuration information. The older, smaller files are still important because they are used for bootable and network connection disks.

• The three following files are the minimum required to make a bootable (startup) disk: – COMMAND.COM– IO.SYS – MSDOS.SYS

6MCT260-Operating Systems I

Critical System Files• After a DOS computer boots up, it reads

the CONFIG.SYS, a configuration file, and executes any commands in it.

• Next the AUTOEXEC.BAT (automatically executed batch) file runs.

• Windows 3.x used initialization files (.INI) for software settings. WIN.INI and SYSTEM.INI are two that are still important in network connection disks.

The Registry

• The .INI files were replaced by the registry in Windows 95.

• The Registry is a database used by the Windows operating system to store configuration information.

• Stores all settings for: Users, Hardware, Programs, and Folders

• Software and hardware installations affect the registry

8MCT260-Operating Systems I

Adding Software• Read the instructions and/or Readme files

• Three options exist for adding software:– Newer programs come on CD-ROMs. If it has an

auto-run feature, the installation program will start automatically.

– Start > Control Panel > Add or Remove Programs > click the Add New Programs button then click the CD or Floppy button. If it can find the SETUP or INSTALL program it will run it.

– Open the disk /folder and double-click any files called SETUP or similarly named files.

Removing Software

• The preferred method is to use Add or Remove Programs since it removes all traces of the program even in the Registry.

• Another option is to see if the program has its own uninstall program and run it.

• The worst option is to delete the files and folder where the program is located

Installing a Printer

• Local printer – one connected to the computer’s parallel port

• Network printer – one connected directly to the network or to a print server

• Having the correct printer driver is very important for a successful installation.– Generally older printer drivers are easily found on

the OS CD-ROM– New printers with older OS’s can cause problems

Using Task Manager

• Use Task Manager to close an application that occasionally freezes or stops responding.

• Use <Ctrl> + <Alt> + <Delete> or right-click on the taskbar and select Task Manager.

• If using Task Manager fails, turn the computer off and restart it.

• It shows a list of open applications, what processes are running, and CPU/memory usage.

Using Device Manager

• Device Manager is used to document system setting, verify the installation of a hardware device, check for hardware conflicts, troubleshoot hardware problems, and change the configuration of a hardware device.

• To view: right-click My Computer, Properties, Hardware Tab, and Device Manager button.

• A red X through an device icon indicates that the device is disabled.
