INDUSTRIAL TRAINING REPORT ON COMPUTER NETWORKING
NETWORKING
A collection of computing devices that are connected in various ways in order to communicate and share resources .
TYPES OF NETWORK
LAN(Local Area Network) WAN(Wide Area Network) MAN(Metropolitan Area Network)
LAN A LAN is a computer network limited to a
small area such as an office building, university, or even a residential home. Most mid to large-sized businesses today use LANs, which makes it easy for employees to share information.
WAN A network that connects two or more
local-area networks over a potentially large geographic distance.
MAN
A metropolitan area network is a network that connects two or more local area networks or campus area networks together but does not extend beyond the boundaries of the immediate town/city.
TOPOLOGIES
A topology describes the configuration of a communication network.
A topology describes the physical and the logical interconnection between the different nodes of a network.
TYPES OF NETWORK TOPOLOGIES
• RING TOPOLOGY• STAR TOPOLOGY• BUS TOPOLOGY• MESH TOPOLOGY
• Ring Topology • A configuration that connects all nodes in a closed loop
on which messages travel in one direction .• Star Topology• A configuration that centers around one node to which all
others are connected and through which all messages are sent .
• Bus Topology• All nodes are connected to a single communication line
that carries messages in both directions . • Mesh Topology• In Mesh Topology each node is connected to every other
node.

BENEFITS OF THE OSI MODEL
Reduces complexity Standardizes interfaces Facilitates modular engineering Ensures interoperable technology Simplifies teaching and learning
SCOPE OF NETWORKING
• All IT/ITES based companies require Networking
• In software Industry also there are Networking Programmers
• Not only IT companies need network all of them need network to reduce workload
