Networking Technologies 1. Considerations for the cable infrastructure (technical specification of and advantages and disadvantages of the following – where appropriate diagrams and illustrations should be used): Name of Cable infrastructure Technical Specification Advantages Disadvantages Cat 5 Twisted pair cable with RJ-45 connectors Speeds of up to 100Mbps Distance of 100 meters Cat 5 is the most affordable of the Cat cables due to this it is often used in crossover. Offers affordable high speed transfer. Of the three cat cables it is the most sensitive to interference. While offering fast speeds in terms of home networking in a business environment the speeds are limited and not ideal for large data streams Cat 5e Twisted pair…show more content…
The electricity consumption of the NIC cards is much higher Thin Co-axial cable with BNC connectors 6 mm in diameter, very flexible, able to transport a signal up to around 185 metres without line loss. Can transfer at speeds of 10 Mbps, easier to work with than Think co-axial cable. more expensive to install compare to twisted pair cable, the thicker the cable, the more difficult to work with. Single Mode Fibre Optic cable and relevant connectors 10Km in distance immunity to electrical noise, greatly increased bandwidth and capacity Components are expensive to produce, fibre optic transmitters and receivers are still relatively expensive compared to electrical interfaces the cable, Multi-Mode Fibre Optic cable and relevant connectors 10 Mbit/s to 10 Gbit/s over link lengths of up to 600 meters in distance. Immunity to electrical noise, greatly increased bandwidth and capacity. Components are expensive to produce, fibre optic transmitters and receivers are still relatively expensive compared to electrical interfaces the cable, 2. Interconnection components (describe the function of): NIC – A NIC or Network Interface Card works on layer 1 (the physical layer) of the OSI model. A network interface cards function is to encode the data to bits that can be sent through the network cable. Repeater – A Repeater also a layer one device is used to extend the range or Wifi or cable by taking the packets being sent and then reforming them to be sent out again.
