Cabling Technology

and Standards



Networks

• Data Communication

– Transfer of digital data between between 2 or more remotelyattached autonomous systems in a reliable and

understandable manner



Networks

• Network – data communication between 2 or more devices with

the ability to access shared resources

• LAN local area network

• !AN wide area network



Networks Topologies

Bus

Ring

Star



• "ubs

• #witches

• $outers

Networks Components



Switch provides a dedicated

communication channelbetween network devices

Hub connects multiple

devices on same network viaindividual dedicated cableruns (star topology)
