Key Components of A Network - Network Interface Card(NIC) + Routers
NIC - Inputted in a slot with a cable pluged into the rear, Connected into a wall jack connected or into the hub/switch directly and Modem - switches digital signals into analog form for transmission and incoming analog signals into digital signal across the telephone line
Routers - LAN to LAN, overlooks network traffic and stops local traffic from causing congestion, clears out packets that need not be received and it it very costly and difficult to operate
Factors in creating a Network - Cost, Capacity, future growth and safety
