  1. Connection Wired- transfers data through wire and cable. Disadvantages- Must be protected from damage, and it take up spaces Advantages-Its cheap and widely available, and it also easy to install. Wireless-moves data through air and spaces. One example of a wireless is a radio and the television. Disadvantages- Advantages-its easy to get connected.

  2. Discuss the advantages and disadvantages of coaxial, cat5 (5e or 6), fiber cabling and wireless. Which one is suitable for peer to peer or client/server and why. e.g. coaxial is suitable for peer to peer but not client server. Fiber is suitable for client/server not peer to peer. • Category 5 cable (Cat 5) is a twisted pair cable for carrying signals. • Fiber cables contains up to a thousand fibers in singles cable. • Wireless is a device that allows wireless devices to connect on different wired network. • Coaxial are used for carrying lower-frequency signals. • Discuss the Disadvantage and advantages. • Fiber is suitable for client server not peer to peer because of the costs. This cable you can run for kilometers in distance which makes it more suitable for LANs. Since peer to peer wont ever leave the confines of your home and/or small business, fiber is overkill. Fiber is also great for Client/server LANs because of speed. It is capable of gigabit speeds and this is an advantage because of how many machines will be using the link. • Wireless is suitable for both LANs because the cost is cheaper and it also can be connected from where you are. • Cat 5 is suitable for both LANs because its cheaper and affords high-transfer speeds e.g. 100mbps but its main disadvantage is you can’t run it very far before the signal fades e.g. 100metres.

  3. Work through this PowerPoint to identify what cabling is best to use in a Peer to Peer vs. Client/Server LAN Peer to peer Client server Coaxial is suitable for peer to peer and not client server Fiber is also great for Client/server LANs because of speed Fiber is suitable for client server not peer to peer because of the costs

  4. Coaxial cable. Fibre cable Wireless Cat5 cable.

  5. 1 – What are these? 2 – Why are they important on a LAN? OSI Model-Stands for Open Systems Interconnection (OSI) model.

  6. Topologies – A topologies is an arrange of cables in a LAN. The most common topologies are ,star, ring, bus and also a hybrid that got all of the mixtures in it. Bus topologies-uses only one cable lines with two end points. At the end point there is a terminator that stops signals at the end of the cable from being reflected back into the network. Advantages: they are cheap and easy to set up. Disadvantages-because one cable carries all the data, it can cause more break downs, once a cable crushes its hard for the others to pass on data or receives.

  7. Star topologies- has a central (hub/switch)and also a computer to which all the computers are connected. Advantages- Each computers has its own cable and does not need to share the line, if one PC is broken down it doesn’t affect the others,new application can be easily added. Disadvantages-if the central hub/switch breaks down then the entire network will stops working. Its expensive and more cable will be needed.

  8. Ring topologies- is made up of PC in a closed chain or circle. Traffic can be in one direction around the circle or both direction if there a double circle. Advantages-there is only one cable that is used to connect all the computers. Disadvantages- If the ring is broken or the cable is not working correctly then the entire network will stop work.

  9. Hybrid topologies- is an combined of a connected bus, star and ring. The bus is usually the backbones of the topologies with the network star hanging off it.

  10. CSMA/CD - stands for Carrier Sense Multiple Access with Collision Detection was designed to stop packets of information colliding on a network segment.

  11. IP Addressing

  12. Data Transmission
