Unit 3: Network Hardware review game

• an added benefit to hardware redundancy is load balancing
• a plenum is a type of twisted-pair cable that is required for running cable through walls or between floors
• the network speed 100 Mbps is represented by the term fast ethernet
• cut-through is a method of data transmission that sends a data frame as soon as it gets the target MAC address
• two devices are involved in a directly connected route
• this ethernet cable category is represented by speeds of up to 10 Mbps at 100m

  Category 3
• which type of fiber-optic cable carries signals for a max of 600m ( 1968.5 ft )

  multimode fiber optic
• this ethernet cable category is represented by speeds of up to 10 Gbps at 37 m

  category 6
