Group4_Newcreation:How does Internet works

Introduction:
Internet is the global network of computers each computer connected to the internet must have a unique address internet address are in the form nnn.nnn.nnn.nnn where nnn must be a number from 0 to 255 this address is known as an IP address.
Computer ----> Internet ----> Computer.
If the computer is connected to the internet through an Internet Service Provider (ISP),the computer will be assigned the temporary IP address for the duration of your dial-in session.If the is connected to the internet through local area network (LAN) it will have a permanent IP address or it might obtain a temporary one from a DHCP (Dynamic Host Configuration Protocal)
server.
Computer Internal Communication Via Internet:
As we know computer has a unique IP address lik comp A has 1.2.3.4 and the comp B may have 5.6.7.8 and if these two computers wants to communicate, and if comp A want to send a "Hello" message to comp B then the message must be transmitted over watever kind of wire connects both the computer to the internet.Lets say both the computer have dialed to ISP from home and the message must be transmitted over the phone line.there fore the message must be transmitted from Alphabetic text in to electronic signals transmited over the internet, then transmitted back in to Alphabetic text.
A simple flow:
Comp A:Application-> TCP -> IP -> Hardware -->INTERNET-->CompB: Hardware -> IP ->TCP -> Application
