LAN are created with help of switched and IP POOL should be same for computers to communicate with each other.
To communicate with other LAN if the ip pool of other LAN is different we have to use router in between to communicate two LAN with each other or we can say router on a stack.
To communicate with other LAN if the ip pool of other LAN is same then we just require switches to communicate two LANs with each other.
To communicate with other LAN if the VLAN of LAN is differnet in this scenario we again need a router on stack technique to communicate LANs with each other.
A layer 2 device is needed to create a LAN. Layer 3 device is needed for LANs to communicate.
We could create LAN by using client pc, switches/hub, RJ-45, cable for connecting the nodes.
planning - router or switch + cables + access points and NAT and devices including pc's and printers .
If you are Create lan network , you can use cat5(100mbps speed),Cat6(1 gbps speed). coper cable 70-80 meter best working if leangth more than 80 use fiber and using Switch for inter communication.
A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide area network .
LAN - Local Area Network, when 2 or more devices are connected then a n/w is established.
LAN is used for communication between two or more systems in a room or in a building.
it helps in sending and receiving the data from one p.c to other.
you can make a LAN connection by making physically connection on them and then provide the specific interfaces on the links of that LAN.
you can use a HUB and Switch for better communication or for extend your LAN network.
It depends that what kind of Network you are going to create but basic need is for creating a network is CAT5 Cables switches or HUB, access points and routers 'OR' if you want to create lan network in single laptop then it's also possible using vmware or some softwares.
Baisc need of communication is reachability that can be done by using cables, WiFi and router
