Document Summary

Broadcast communication: single sender, many receivers (radio, tv) Term multicast is used when there are many receivers but the intended recipients aren"t the whole population (magazines) Point to point communication: opposite of broadcasting and multicasting: have one specific receiver, one specific sender. Internet supports point to point asynchronous communication: on internet computers and network become a single medium that can be applied in many ways to produce alternatives to established communications, internet can mimic synchronous communication. Client-server interaction: protocol for most internet interactions: client receives services from another computer, server can handle many clients at a time. Software has been built on internet to implement many forms of communication we use. Each computer connected to the internet is given a unique address (ip address) internet protocol address: sequence of 4 numbers separated by dots. Range of each of 4 numbers is 0-255.
