Applications of the Internet

How the Internet Works with details

• WWW(World Wide Web)
• Email(electronic mail)
• Instant Messaging

lets,starts with

Underlying Principles of the Internet - Packet Switching

                                 

• The Internet Was First Conceived in 1969 as ARPANET (Advanced Research Projects Agency Network) Which was used to connect computers in geographically dispers research centers.
• ARPANET was the first major implementation of a packet switched network.
• In packet switching data is assembled into packets which are then Indepentaly routed (using routers,wi-fi),to their desitination through various links over the networks.
• this lead to distribution of resources,an increase in resource utilization,and incresed fault tolerence sinse a packet may take aternative routes to reach its designation.
• the destination node is receives these packets and re-assemble them to construct the original message
• This breakthrough was that made internet a reality.
