tell me about networking

Dear student, It is really difficult to discuss networking in short. However as you asked , I'm trying: computer networking is meant for data communication from one node to another desired node.When the nodes are inter connected based on n/w components hub/switch then they may be termed as LAN connectivity and the ip's provided against each node from the same ip pool. However any of the nodes if requires internet connection for a particular purpose must be connected through router which in turns takes the support sp's transmission media through modem and provider's router to be connected with the internet cloud. For the WAN connectivity the same process is followed where in lieu of connecting to internet cloud it is allowed to use providers WAN network cloud to be connected with distant end of the same customer using tunneling protocol. This is too brief and may require modification. For a clear idea you may need to go through right from OSI layered architecture, TCP/IP protocol , Ethernet and computer n/w and data communication as a hole which is interesting and professionally attractive also. Best wishes.
