Networking involves connecting computing devices to communicate and share resources. There are different types of networks including LANs (covering a small area like a home or office), WANs (connecting LANs over large distances), and MANs (spanning an area larger than a LAN but smaller than a WAN, typically within a city). LANs are commonly used in businesses to allow employees to easily share information. LAN topologies include ring, star, bus and mesh configurations. WANs connect multiple LANs over large geographic distances, while MANs operate within a single region like a city. Computer networking uses models like the OSI model to function across different layers from physical to application. Networking is

2. NETWORKING

A collection of computing devices that are
connected in various ways in order to
communicate and share resources .

3. TYPES OF NETWORK



LAN(Local Area Network)
WAN(Wide Area Network)
MAN(Metropolitan Area Network)

4. 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.

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.

8. WAN
A network that connects two or more local-area
networks over a potentially large geographic
distance

9. MAN

A network spanning a physical area larger than
LAN but smaller than WAN such as a city. A MAN is
typically owned and operated by a single entity
such as a government body or large corporation .

12. 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
