Communication network can be generally viewed as Switched & Broadcast.In switched network comes Circuit & Packet Switched network.Circuit Switched Network are used by Telphone,GSM.Packet Switched network are further sub divided into Datagram & Virtual Circuit.Datagram circuit followed by internet,IP network whereas Virtual circuit example is ATM .
Network can be identified by their topology , architecture , size which will be defines as the following :
1) Topology :
A) star network : all devices are connected by a central device
B)buss network : all devices are connected by a central cable
C) ring network : all devices are connected in closed loop
D) mech network : multiple connection between devices
E) combination network : some networks are combined with different topologies such as network
2) architecture :
A) client-server networks : client is a PC. or other device on the network that request and utilize network recources . Server is a computer dedicated to process client requests
B) peer-to-peer networks : all computers on the network at the same level , a server is not used
3) size :
A) WAN = Wide Area Network - A network that covers a broad area, either locally or nationally. Such networks are usually used by companies for communication between offices etc.
B)LAN = Local Area Network - A network that covers a small local area like a single building,an airport or a few rooms. More specifically, a single group of computers like schools' computer.
These networks can be either wired or wireless depending on the area and budget.
communication links
different types of computer network are:
LAN,MAN,WAN
The types of communication channels are physical and wireless. The communication channel is what carries the message that originated with the sending device.
LAN,WAN and MAN.
WALKIE-TALKIES
Walkie-talkies
b. Walkie-talkies(Answer from chapter 3 of "Network+ Guide to Networks")
Communication systems are a collection of networks, relay stations and systems, they are used so these types networks can interconnect. For example you have multiple TV channels which pass through the communication system and come out the other end through a receiver on your TV.
There are many common communication networks in households these days. Some common communication networks in households these days includes Charter Communications and AT and T.

Networks are the main source of communication and sharing resources.
