Company Access

Company  access is that in which  end systems are connected in connecting end  systems in a organization or educational  institution into the network.

On  corporate and  university campuses a local area network (( LAN)  is typically  used  to connect end systems through  the edge router. Ethernet technology is currently by far the most  prevalent access technology in company  networks. Ethernet operates at 10 Mbps or 100Mbps(and  now even at 1 Gbps and 10 Gbps) it  uses either twisted pair  copper wore or coaxial  cable to connect a number of end systems with each  other and  with an edge router. The  edge router is responsible  for routing packets that have destinations  outside the LAN like HFC Ethernet tuxes a shared medium so that end  users can there  the transmission rate of the LAN. More  recently shared Ethernet technology has  been  migrating toward switched Ethernet technology . Switched Ethernet  uses  multiple twisted pair Ethernet  segments connected at a switch to allow  the full transmission rate of  an Ethernet to be delivered to different  users  on the same LAN simultaneously.
