- Twisted Coaxial
-bus topology- advantages, disadvantages
-star topology - 2RoutersA router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet.
- 3SwitchersA switch is used to network multiple computers together.
- 4Fibre OpticA technology that uses glass (or plastic) threads (fibres) to transmit data. A fibre optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
- 5CoaxialCable consisting of a single conductor which is surrounded by insulation and a conductive shield. The shield usually is connected to an electrical ground and prevents the cable from picking up or emitting electrical noise. Coaxial cables are generally used in communications.
- 6Twisted PairTwisted pair is the ordinary copper wire that connects home and many business computers to the telephone company.
- 7Bus Topologya bus topology is single line/cable with a start and end terminator. a printer and other peripheral devices can be connected on the same line
- 8Bus Topology Advantageseasy to install
easy to add extra workshops
uses less cable than a star network
best choice for temporary network - 9Bus Topology Disadvantagesif there is a problem with the central cable the entire network stops working
if there is a lot of work stations on the network data can travel slowly
data collisions can happen as the network becomes busy
low security very workstation can see al the data in the network
limited cable length and a maximum number of workstations - 10Star Topologywhen a group of computers re connected to a central hub or server. each computer must have their own separate cable to connect to the hub or server.
