Sarkar and others published Computer Networking and Hardware Concepts.
The tree can have only levels: level 0 root to level A full domain name is a sequence of labels separated by dots. A PQDN starts from a node, but it does not end with the root. Question 6. This loss of energy is called the Attenuation. To overcome this problem, amplifiers are used to amplify the signal.
Close the side doors of the cabinet and get it upright and place it on your computer table. Get the rest of the PC components like monitor, keyboard, mouse, speakers etc.
Power on and see your rig boot to glory. Step Installing the OS and drivers We are done with the hardware part. Now get your favorite OS disks ready and the CD that came with your motherboard. Soon as computer starts booting from the CD your will get the following screen: Step 2 - At this stage it will ask you to press F6 if you want to install a third party Raid or SCSI driver.
Please make sure you have the Raid drivers on a floppy disk. Normally the drivers are supplied on a CD which you can copy to a floppy disk ready to be installed. If you are not sure how to do this then please read your motherboard manuals for more information.
Step 3 - Press S to Specify that you want to install additional device. Press enter after you have inserted the disk. Select the correct driver for your device and press enter. You have the option to do a new Windows install, Repair previous install or quit. Since we are doing a new install we just press Enter to continue. Press F8 to accept and continue Step 8 - This step is very important.
Here we will create the partition where Windows will be installed. If you have a brand new unformatted drive you will get a screen similar to below. In our case the drive size is MB.
We can choose to install Windows in this drive without creating a partition, hence use the entire size of the drive. If you wish to do this you can just press enter and Windows will automatically partition and format the drive as one large drive. However for this demonstration I will create two partition. By creating two partition we can have one which stores Windows and Applications and the other which stores our data. So in the future if anything goes wrong with our Windows install such as virus or spyware we can re-install Windows on C: drive and our data on E: drive will not be touched.
Please note you can choose whatever size partition your like. For example if you have GB hard drive you can have two partition of GB each. Press C to create a partition. Step 8 - Windows will show the total size of the hard drive and ask you how much you want to allocate for the partition you are about to create.
I will choose MB. You will then get the screen below. Notice it shows C: Partition 1 followed by the size MB. This indicates the partition has been created. We still have an unpartitioned space of MB.
Next highlight the unpartitioned space by pressing down the arrow key. Then press C to create another partition. You will see the total space available for the new partition.
Just choose all the space left over, in our case MB. Step 9 - Now you will see both partition listed. You will also have 8MB of unpartitioned space. Don't worry about that. Just leave it how its is.
Windows normally has some unpartitioned space. You might wonder what happened to D: drive.
Select Partition 1 C: Drive and press Enter. This is the recommended file system.
If the hard drive has been formatted before then you can choose quick NTFS format. We chose NTFS because it offers many security features, supports larger drive size, and bigger size files. Windows will now start formatting drive C: and start copying setup files as shown on the two images below : Step 11 - After the setup has completed copying the files the computer will restart.
In few seconds setup will continue. Windows XP Setup wizard will guide you through the setup process of gathering information about your computer. Step 12 - Choose your region and language. Step 13 - Type in your name and organization. Step Enter your product key. Step 15 - Name the computer, and enter an Administrator password. Don't forget to write down your Administrator password. Step 16 - Enter the correct date, time and choose your time zone. Step 17 - For the network setting choose typical and press next.
Step 18 - Choose workgroup or domain name. If you are not a member of a domain then leave the default settings and press next. Windows will restart again and adjust the display.
Step 19 - Finally Windows will start and present you with a Welcome screen. Click next to continue. Step 20 - Choose 'help protect my PC by turning on automatic updates now' and press next.
Step 21 - Will this computer connect to the internet directly, or through a network? If you are connected to a router or LAN then choose: 'Yes, this computer will connect through a local area network or home network'. If you have dial up modem choose: 'No, this computer will connect directly to the internet'. Then click Next. Step 22 - Ready to activate Windows?
Choose yes if you wish to active Windows over the internet now. Choose no if you want to activate Windows at a later stage. Step 23 - Add users that will sign on to this computer and click next. Step 24 - You will get a Thank you screen to confirm setup is complete.
Click finish. Log in, to your PC for the first time. Step 26 - You now need to check the device manager to confirm that all the drivers has been loaded or if there are any conflicts. Click on the System icon and then from the System Properties window select the Hardware tab, then click on Device Manager. If there are any yellow exclamation mark "!
Your hardware should come with manufacturer supplied drivers. You need to install these drivers using the automatic setup program provided by the manufacturer or you need to manually install these drivers.
If you do not have the drivers, check the manufacturers website to download them. To install a driver manually use the following procedure: a From the device manager double click on the device containing the exclamation mark.
The Wizard for updating device driver pops up as shown below: You now get two options. The first option provides an automatic search for the required driver. The second option allows you to specify the location of the driver. If you don't know the location of the driver choose the automatic search which would find the required driver from the manufacturer supplied CD or Floppy disk.
Windows would install the required driver and may ask you to restart the system for the changes to take affect. Use this procedure to install drivers for all the devices that contain an exclamation mark. Windows is completely setup when there are no more exclamation marks in the device manager.
We will see the wallpaper and the installation wizard. Select your language and click the "Install Ubuntu The second screen will feature a map of the Earth.
Upon the selection of our current location, the time for the final system will adjust accordingly. We can also select our current location from the drop-down list situated at the bottom of the window.
Click the "Forward" button after selected your desired location Test the keyboard On the third screen, we will be able to choose a desired keyboard layout. But the default automatic selection should work for most of us. Click the "Forward" button when you have finished with the keyboard configuration Hard disk partitioning We have four options here: 1.
If we have another operating system e. Windows XP and we want a dual boot system, select the first option: "Install them side by side, choosing between them at each startup. Remember that, after the installation, the Windows boot loader will be overwritten by the Ubuntu boot loader! If we want to delete our existing operating system, or the hard drive is already empty and we want to let the installer automatically partition the hard drive, select the second option, "Use the entire disk.
The third choice is "Use the largest continuous free space" and it will install Ubuntu 9. The fourth choice is "Specify partitions manually" and it is recommended ONLY for advanced users, to create special partitions or format the hard drive with other filesystems than the default one. So, make sure that we know which is the one we want to format! Otherwise, will lose ALL DATA on that hard drive; - Let's say that the selected drive is empty no other operating system or important data on it , but it has some partitions on it.
Select each one of those partitions and click the "Delete" button. After a few seconds, it will say "free space. In the new window, type in the "New partition size in megabytes" field and select the "swap area" option from the "Use as:" drop down list. Click the OK button and, in a few seconds, we can see a "swap" line with the specified size; - With the "free space" line selected, click on the "Add" button. This is how our partition table should look like.
If so, click the "Forward" button to continue with the installation It often contains oversimplifications of reality and every technical detail is purposely omitted.
