2. It allows for more convenient resource sharing.   

3. It makes file sharing easier.    

A local-area network (LAN) connects the computer hardware in a localized area such as an office or home. Typically, LANs use wired connections to link the computers to each other and to a variety of peripheral devices such as printers.

Types of Network Topologies: The mapping of a LAN design is called Topology. There are four categories: Star topology, Bus topology, Ring topology and Mesh topology. Hybrid combinations of these topologies also exist.

cket tracer provides multiple opportunities for instructors to create different networking scenarios to explain different networking concepts. Since packet traceris not a replacement of real equipment but it helps a student to do lot of practice and gain lot of confidence so that it's easy to work on a real network

In a half duplex mode, signal is sent in both directions, but one at a time. ... In asimplex mode, only one device can transmit the signal. In a half duplex mode, both devices can transmit the signal, but one at a time. In a full duplex mode, both devices can transmit the signal at the same time.

The main difference between the Client-Server and Peer-to-Peer network model is that in Client-Server model, the data management is centralised whereas, in Peer-to-Peer each user has its own data and applications.

he most basic explanation is that a switch isdesigned to connect computers within a network, while a router is designed to connect multiple networks together. ... Even though routers and switches are different, they can be used interchangeably. For example, a router typically has several LAN ports and a single WAN port.

Packet Tracer. Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switche

 
Types of Media Used in Computer Networking. There are three general classes of media types: coaxial cable, twisted pair and fiber optic cable.
   
While bandwidth is traditionally expressed in bits per second (bps), modern network links have greater capacity, which is typically measured in millions of bits per second (megabits per second, or Mbps) or billions of bits per second (gigabits per second, or Gbps).
