Chapter 13/Operating System Administration Flashcards
we interact with an operating system throw
what?
610
1-control panel
2-the command prompt
3-the windows registry
4-virtual memory
Applet ( table to check )
611
An applet is a small, supplemental program that does a job a larger program is incapable of doing.
1- control panel
610
The Control Panel is a section of Microsoft Windows that enables a user to change various computer hardware and software features. Settings for the mouse, display, sound, network, and keyboard represent and more by using applets
The Regional and Language Options is configured through which control panel applet?
613
in window 7 =Region and language
in window vista/ XP = Region and language options

The folder option applet
613
some of the files are hidden by default for security
The system control applet: deferent OS has different options available in this applet some of them are
615
General Network identification hardware hardware profiles User profile Environment Variables System restore Automatic updates Remote Computer name Advanced
computer name tab
616
is the machine:
workgroup
domain
Advanced tab has three subheadings they are deferent on each OS, they include
617
performance
Environment variables
user profile
start up and recovery
performance
617
Visual effects, processor scheduling, memory usage and virtual memory,
Environment variables; two types
618
user variable is set for one user and dose not effect other users who login to the machine.
system variable is set for all users, it provide information needed by the system when running app or performing tasks
user profiles
618
every user is giving a user profile when they login to their machine, that profile contains the information of their setting and preferences.

MS-DOS
620
Short for Microsoft Disk Operating System, MS-DOS is a non-graphical command line operating system derived from 86-DOS that was created for IBM compatible computers. MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line instead of a GUI like Windows.
2-the command prompt
620
Today, MS-DOS is no longer used; however, the command shell, more commonly known as the Windows command line is still used by many users. The picture to the right, is an example of what an MS-DOS window more appropriately referred to as the Windows command line looks like running under Microsoft Windows.
command prompt utilities are divided in to two categories
621
2-1 Networking command line tools
2-2 OS command line tools
2-1 Networking command line tools we need to know are
621
PING, TRACERT, NETSTAR, IPCONFIG, NET, NSLOOKUP, and NBTSTAT.
PING command
622
Short for Packet Internet Groper, PING is one of the most useful command in the TCP/IP.
is a utility used to verify whether or not a network data packet is capable of being distributed to an address without errors. The ping utility is commonly used to check for network errors.
there are several options for ping command, we can see them by typing ping /?
ping options
622
ping -4 is used to IPv4
ping-6 is used to IPv6
TRACERT command
623
is a command line utility that enable you to verify the route to a remote host, we execute the TRACERT hostname ( the hostname is the computer name or the IP addresses).
The tracert command is used to visually see a network packet being sent and received and the amount of hops required for that packet to get to its destination.
NETSTAT command
623
check out the inbound and outbound of TCP/IP connection, and the number of errors.
network statistics, the NETSTAT command is a command found in almost all command line environments that allow you to view the statistics of the network.
there are some useful options for NETSTAT ( table)
624
-e display Ethernet statistic
-f display fully quality Domain name
more options in the table
IPCONFIG command
625
IPCONFIG is a DOS utility that can be used from to display the network settings currently assigned and given by a network. This command can be utilized to verify a network connection as well as to verify your network settings on the client’s network interface cards.
IPCONFIG switches
625
/ALL shows full configuration
/RELEASE Releases if you are getting the address from an Dynamic Host configuration protocol (DHCP)
NET command
629
is one of the most powerful commands, the capabilities of this command differ if it is a workstation or server and the version of the OS, it has so many switches.
OS command line Tools
631
we need to know these tools
TASKKILL, BOOTREC, SFC, SHUTDOWN, TASKLIST, MD,RD, CD, DLE, FDISK, FORMAT, COPY, XCOPY, ROBOCOPY, DISKPART, SFC, CHKDSK, AND /?
TASKKILL
Allows a user running Microsoft Windows XP professional, Windows 2003, or later to terminate a process from an Windows command line by process id (PID) or image name.
Windows Registry
639
The Registry or Windows Registry contains information, settings, options, and other values for programs and hardware installed on all versions of Microsoft Windows operating systems.
Virtual memory
641
Virtual memory is a method of using the computer hard drive to provide extra memory for the computer, it uses a swap file or a paging file. Segments of memory are stored on the hard drive known as pages. When a segment of memory is requested that is not in memory it is moved from the virtual memory to an actual memory address.
Task Manager
642
The Task Manager is an operating system component found in all versions of Microsoft Windows
It enables a user to view each of the tasks currently running on the computer, each of the processes, and the overall performance of the computer. The Task Manager is accessed by pressing Ctrl + Alt + Del on the keyboard and selecting “Task Manager” or “Start Task Manager”.
