This was an inclass project. We disconnected our computers from the college network and added them to a switch in the classroom. We then had to download Advanced Port scanner. I accidently downloaded another program that opened another port. Most everyone had 8 ports open I had 9. We then opened a telnet port. We had to make sure that we disabled our firewall and we pinged everyones computer with the Ping command through the CLI. Ones we did that we were able to see which ports were open on all the other computers.

chapter 18 lab

For the chapter 18 lab we disconnected our computers from the network and added them all to a switch. We were all given IP addresses by Brad and then we had to ping each other using the command interface. to make sure we were all on the network. We then checked to make sure that we could view each other through the my network console in windows explorer. We then created a document and put it in a folder that we had to share. We had to make sure that password sharing was turned off.

Defraging the hard drive


I used the tools to analyze disk C to see if it needed to be defragmented. After it analyzed the disk it said that the drive was 0% defragmented.

Check disk

I used the tools to check the disk for errors. I scheduled it to check the next time I logged off. After verification it said I had 53 large files and 0 bad files the check disk went through 5 steps: File verification, index verification, security descriptors verification, file verification, and free space verification.

Verify start up programs

I choose to let windows choose which files to backup, the other option was to let me chose. Windows choose to backup all users. I then put a disk in the drive and when that one was full back up asked me to put in a new disk. It took 4 disks to backup my home computer.

Lab 4-1

For this lab we had to take a computer apart and then put it back together. I took a part my computer at school and put it back together and I am going to discuss the steps I did. I also toke a computer apart that I had at home That I plan to rebuild.
1. The first steps in taking the computer apart was that we had to take out any adapter cards that were plugged into the motherboard as well as take out all the RAM that was in the motherboard.
2. I then disconnected all the IDE cables and power cables from the motherboard.
3. I then proceeded to take out the screws to remove the power supply from the case.
4. I then removed the CPU fan and then the heat sink from the motherboard. The one I had at home also Had a heat sink over a chip on top of the mother board.
5. I then unscrewed the motherboard from the case and lifted it out of the case.
6 I then removed the hard drive, floppy drive and optical drive from the case.
7 On the computer I have at hope I removed all of the case peripherals so that I could thoroughly clean the case.
Ones I finished I reassembled the computer at school opposite the way I took it apart.
Hear are some pictures that show how this was done and the end result.

Lab 3-1

4. I don't like dealing with people on the phone however in the past when having to deal with people in a support position over the phone my strength is being able visualize the screen in order to help someone figure out what went wrong.

pc cleaning lab

In this lab at school we took our pc's downstairs and used compressed air to clean all the dust from inside and outside the computer case. We had to make sure that we dusted odd the connections and devices as well as the fans inside the case. I was unable to get a picture of me cleaning the case but I have a picture of the inside of the case all nice and clean.
