Lab 4.1: Copper Cabling
4.1.1:
So that NIC’s on different ISP providers can communicate to each other.
4.1.2:
The copper wiring is used to power appliances and other devices so it has a high capacity for transmitting electricity.
4.1.3:
More expensive shielded cables cause far less interference. Steel reinforced concrete, radio transmitters.
4.1.4:
Category | Maximum Speed | Application | 1 | 1 Mbps | Telephone cabling (POTS) | 2 | 4 Mbps | Token Ring | 3 | 10 Mbps | Token Rink | 4 | 16 Mbps | Token Ring Networks | 5 | 100 Mbps | Ethernet, Fast Ethernet, Token Ring | 5e | 1Gbps | Ethernet, Fast Ethernet, Gigabit Ethernet | 6 | 10 Gbps | GigabitEthernet, 10G Ethernet | 6a | 10 Gbps | GigabitEthernet, 10G Ethernet |

4.1.5:

4.1.6:
Plastic jacket, metallic shield, dielectric insulator and center core.
4.1.7:
Only good under 100 meters
4.1.8:
Both straight and crossover cables
4.1.9:
S2 to G is too far away to work. Fiber optics would be needed.
4.1.10:
Multi-meter: It can be used to locate the failure of electrical system and the defective parts.
Tone generator: It acts as a testing device for informational signals that come handy when dealing with telephone systems.
Pair Scanner: Identifies connection hosts on a subnet.
Time Domain Reflectometer: Locate and identify faults in all types of metallic cables
Lab 4.1 review: 1. Less confusion, need only one type of cable easier to install, less time consuming. 2. By the time the signal gets to the end of the cable, it may weaken so it may need to be strengthened. 3. Maximum number of network connections, without traffic collisions, or interference Is up to 15 concurrent connections
Lab 4.2 Fiber Optic Cables:
4.2.1:
Receives simultaneously.
4.2.2:
Total Internal Reflection- the walls of the fiber don’t absorb any light at all as long as the angle of the incidence is greater than the critical angle.
4.2.3:
Bounces off.
4.2 Review:
1. 25mm and it may cause breakage.
2. Cladding, buffer, outer jacket, strengthener
4.3: Cable exploration
4.3.1:
Type | Maximum Distance | Maximum Speed | Cost | Pros | Cons | UTP | 100m | 1Gbps | low | Easy to install, inexpensive, NICS are common on all devices | Limited distances, subject to interference | Coaxial (Thinnet) | 500m | 100Mbps | Low cost | Good in office networks for data transfer | Bad long distance | Coaxial (Thicknet) | 500m | 100Mbps | Low cost | Good in office networks for data transfer | Bad long distance | MMF | 2km+ | 100Gbps | High Cost | Good in connecting local networks and immune to EMI | Need skills and very costly. | SMF | 10km+ | 100Gbps | High Cost | Best for distance and immune to EMI | Can only send one signal at a time and needs the skill to get it right |

4.3.2:
#1 SMF
#2 SMM
#3 UTP
4.3.3:
Network A: Use UTP to connect all the pcs
4.3.4:
Use the Coaxil (Thicknet)
Use UTP cables to connect to PCs a-c to R1.
Lab 4.3 Review: 1. Fiber would need to be installed in most places. There are only a handful of places that have fiber running through them. The process of installing fiber is still a very expensive property. 2. Wireless would be good for people who are mobile around the office or for visitors to your site. Wireless would be good in a pinch but not truly effective.
Lab 4.4: Cable Troubleshooting
4.4.1:
The device is working properly. There is no other information
4.4.2:
Flow Control, Priority and VLAN, Receive buffers. Driver provider, Driver date, Driver version, Digital signer.
4.4.3:
Noise: interference (static) that destroys the integrity of signals on a line. UTP.
Crosstalk: disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit. Coaxial.
Interference: EMI. UTP.
Open (open circuit): Coaxial
Short (short circuit): Coaxial
Break: Single and Multi-layer Optic Fiber (SMF,MMF)
4.4.4:
I would open my control panel and see what is going on.
4.4.5:
Bottom Up: This approach starts from the OSI model’s physical layer and moves up toward the application layer.
Top Down: The top-down troubleshooting method uses the OSI model as a guiding principle.
Lab 4.4 Review: 1. Network Layer. 2. So just in case you don’t have to waste money buying a new one. Last resort.
