DATA COMMUNICATIONS
When we communicate, we are sharing information. This sharing can be local or remote.
Between individuals, local communication usually occurs face to face, while remote communication takes place over distance.
NETWORKS
A network is a set of devices (often referred to as nodes) connected by communication links. A node can be a computer, printer, or any other device capable of sending and/or receiving data generated by other nodes on the network
