Networking Lab 4

Lab Name: B and C network
Date: 9-21-07
Name: Leo Burke


Objectives:
in this lab we were to set up a simple B and C network, and then to link both of those networks together via a router. Each computer on the network needs to have it's unique IP address, subnet mask, and gateway address.

Equipment List
Lab Computer
Switches
Cisco Router
HyperTerminal
Cat 5 Cables

Notes and observations
This lab was kind of difficult compared to previous ones, only because of the technical difficulty and the number of steps involved. Making the C and B networks work was easy. Getting those networks to talk to each other using the router was another story. Using the hyperterminal to assign the IP address to the network ports on the router was a very tricky process, and it needed to be done more than once to make it work completely. After we got everything working, we had to turn off the fire wall in order to get everything to work.

Questions:
How many bits are in an ip Address? 32


What three things are required to properly configure an IP address? Unique IP for Router, Subnet mask, and Unique IP for Computer

When Configuring an IP address, computers on the same network should have a same network address and unique host address.

Conclusions:
This lab was a little more hands on than previous labs, which made things a bit more interesting. I liked the fact that this lab had useful applications in the real world. Before, I had no idea how to set up a network, assuming it was done through a windows wizard, now I know it's through IP assignments and other techniques. I also know now to turn off the fire wall when making the initial connections, so that computers can ping each other without hassle. I also know how to assign IP addresses to a Cisco router using hyper terminal, which may come in handy one of these days. Other than that, it was a very informative lab.

Networking Lab 3

Lab Name: OSI Model
Date: 9-21-07
Name: Leo Burke

Objectives
In this lab we were to learn more about the OSI model by researching and work with each layer. We were also to describe the layers in a mnemonic device.

Equipment list
Computer
internet
Serial cable
Lab computers

Notes and observations
the lab was easy to complete at home, the only problems I had was the last question, which required the hook up of 2 computers using a serial cable. Since I didn't have easy access to these, I waited until the next lab and stayed a little later to complete the question using the lab computers.

Wikipedia entry for OSI Model

Questions

1. If we already had the TCP/IP model, why was the more complicated OSI model created?

To allow for protocols

2.What does the abbreviation OSI stand for? Who originated it? When?

Open Systems Interconnection, originated at the International Organization for standardization in 1977

3. (See Diagram)

4.
Switch, 2
Hub, 1
NIC, 2
Router 2
Cable, 1
Wireless 3
Patch panel 2
Bridge, 1

5. What is another name for a physical address?

Mac address,

How many bits do they require?

12 bits

When two machines attempt to transmit simultaneously on the same media segment, both messages become garbled and unintelligible. What is this condition normally called?

it’ a data collision

6.
What method is used to translate a known layer 3 address into an unknown layer 2 address? VLAN configuration.

7. What is your neighbor’s physical address?
Neighbors’s address is 66.55.155.191

. What address is added to the arp table when you ping www.sal.ksu.edu?
None, the requests times out.

8.

What are layer 3 gateway devices called?

Firewalls

What is the de-facto standard for logical addresses used today?

IP Addresses,

How many bits do they require

12 Bits

9.

Information provides how many server hops a ping goes through to get to it’s destination. The packets seem to go from Salina Kansa to Atlanta Georgia and back. In the console, the number of hops is around 15, from 4 KSU servers to a few others before reaching KWU's servers.

10.

1. What information is provided in the switch MAC address table?

Information on what Vlan is used, what the MAC address is, The type of port (Dynamic or static) and what ports are used.

Conclusions
This lab was not as hands on as other labs, however, I gained a few extra skills. I know the OSI model more than I used to. I also learned to use the "Tracert" command to find where my packets go. Other than that, it was a very long lab which took me a long time to complete. My only problem was going into the lab and connecting 2 computers via serial cable, which was hard only because I had to find time to do it during the week.

Networking Lab 2

Lab Name: Network Cabling

Date: 9/9/2007

Name: Leo Burke

Partner: Thomas Neito

Objectives: From a spool of Catagory 5 wire, we were to strip the wire, unwind, and wire it into a network cable, and a crossover cable.

Equipment list:

Cat 5 wire

Network clips

Scissors

Cable insulator scoring device

Network Crimper.

Notes and Observations: The hard part of this lab was getting the wiring right. In order for a network or crossover cable to work, the wiring had to be set up just right. Working with it turned out to be very problematic, and required multiple attempts. However, we persevered and eventually got the wires corrected.

Questions:

1.The purpose of the twisted wires is to prevent crosstalk between wires.

2.Thinnet, which is coaxial cable, is a cheap alternative to UTP. UPT stands for unprotected twisted pair. Both can carry an ethernet signal, but UTP is used everywhere anyway, and is much easier to set up.

3.It is important not to untwist the cables as much as possible, because a break in the twist might induce crosstalk, making the rest of the cable's twisting pointless.

Conclusions:

The lab went well, as well as it could have for being my first experience at making a cat-5 cable. At first it was very difficult ordering the color-coded wires and getting them inside the clip properly. After at least 2 tries, the cable was finnaly wired correctly with the clip contacts. Wiring the cable up to the data jack was a little difficult, since I had to see an example before I could get it right, but once I did, it was very easy. Now I have a crossover cable, and a network cable, and I know how to make both.
