Local-area network (LAN)Local-area network (LAN)
A A local area networklocal area network ( (LANLAN) is a ) is a computer computer networknetwork that interconnects that interconnects computers within a limited computers within a limited areaarea such as a such as a home, school, computer laboratory, or home, school, computer laboratory, or office building, using office building, using networknetwork media. media.

MMetropolitan Area Network etropolitan Area Network (MAN)(MAN)
A A Metropolitan Area NetworkMetropolitan Area Network (MAN) (MAN) is a large computer is a large computer networknetwork that spans a that spans a metropolitan areametropolitan area usually within a city usually within a city or mega city. Its geographic scope falls or mega city. Its geographic scope falls between a WAN and LAN.between a WAN and LAN.

A A wide area networkwide area network ( (WANWAN ))
A A wide area networkwide area network ( (WANWAN ) is a ) is a network that covers a broad area (i.e., any network that covers a broad area (i.e., any telecommunication network that links telecommunication network that links across metropolitan, regional, national or across metropolitan, regional, national or international boundaries) international boundaries)

Network TopologyNetwork Topology
The network topology defines the way in The network topology defines the way in which computers, printers, and other which computers, printers, and other devices are connected. A network devices are connected. A network topology describes the layout of the topology describes the layout of the wire and devices as well as the paths wire and devices as well as the paths used by data transmissions.used by data transmissions.

BUSBUS Commonly referred Commonly referred
to as a l inear bus, to as a l inear bus, all the devices on a all the devices on a bus topology are bus topology are connected by one connected by one single cable.single cable.

STARSTAR In Star topology, all the In Star topology, all the
components of network components of network are connected to the central are connected to the central
device called “hub” which device called “hub” which may be a hub, a router or a may be a hub, a router or a
switch. switch.

RINGRING
In Ring Topology, all the In Ring Topology, all the nodes are connected to nodes are connected to each-other in such a way each-other in such a way that they make a closed that they make a closed loop or a circle.loop or a circle.

MESHMESH In a mesh network topology, In a mesh network topology,
each of the network node, each of the network node, computer and other devices, computer and other devices, are interconnected with one are interconnected with one another. Every node not another. Every node not only sends its own signals only sends its own signals but also relays data from but also relays data from other nodes.other nodes.
Internet is a mesh network.Internet is a mesh network.

TREETREE
In Tree Topology, the In Tree Topology, the number of Star number of Star networks are networks are connected using Bus. connected using Bus. This main cable This main cable seems like a main seems like a main stem of a tree, and stem of a tree, and other star networks as other star networks as the branches. It is the branches. It is also called also called Expanded Star Expanded Star TopologyTopology . .
