Chapter 1: Network Concept
Technology Brief
The network is an accumulation of PCs and other networking devices such as databases, servers, and firewalls interconnected with each other through a communication channel that permits sharing of information among them. Network Fundamentals help to understand how to configure a functional network. This network may be either deployed locally or spread over a wide area.
The most widely recognized system types are:
 Local Area Networks(LANs)
 Wide Area Network(WAN).
A noticeable distinction between these two is that a LAN is restricted to a constrained land territory, while a WAN covers a huge geological zone. Most WANs comprise of a few associated LANs. Furthermore, a network can also be classified into the following additional types:
 Metropolitan Area Network (MAN)
 Personal Area Network (PAN)
 Storage Area Network (SAN)
Network Fundamental focuses on incorporating WANs’ innovations, basic security, wireless concepts, routing, and switching fundamentals, and designing a simple network.
