A hub. broadcast Transmission of data by a hub to all devices connected to its ports switch Device used at the center of a star topology that forwards a frame it receives directly out the port associated with its destination address mesh topology All networking devices are directly connected to each other, allows for full redundancy OSI model The seven layers describing network functions Physical layer Provides the electrical and mechanical connection to the network (cabling, NICs). 1st OSI layer Data link layer Handles error recovery, flow control (synchronization), and sequencing (MAC, Ethernet). 2nd OSI layer Network layer Accepts outgoing messages and combines messages or segments into packets, adding a header that includes routing information (IP, IPX). 3rd OSI layer Transport layer Concerned with message integrity between source and destination (TCP, UDP). 4th OSI layer Session layer Provides the control functions necessary to
