  1. Network Components Cabling and Bandwidth

  2. Physical Network Connections: • ALL network devices need a Network Interface Card (NIC) • NICs have specific types of connections e.g. RJ45 • Connection types dictate cables • Cables dictate bandwidth

  3. What is bandwidth? • How much data can travel from A to B in a period of time. • Measured in bits per second (bps) • Which device is faster? Speed Test

  4. BNC for Coaxial Cable • 10Base2 and 5 • 10megabits per second (Mbps) • 200 – 500 metres

  5. RJ45 for Ethernet Cable (e.g. Cat5) • Cat5 – 10/100 Mbps • Cat5e/Cat6 – 1000 Mbps • 100 metres

  6. SC, ST and LC for Fibre Optic Cable • 100 Mbps; 1 Gbps - 50 Gbps • Can run across kilometres

  7. Read about these cables: • http://www.windowsnetworking.com/articles_tutorials/copper-glass-guide-network-cables.html • http://www.howtogeek.com/70494/what-kind-of-ethernet-cat-5e6a-cable-should-i-use/ • http://compnetworking.about.com/od/networkcables/g/fiberopticcable.htm

  8. Q – Which cable would you use and why?
