Introduction:-
Internet is the network of networks. The Internet’s growth has become explosive & it seems impossible to escape the bombardment of www.com seem constantly on television, heard on radio & seen in magazines. Because the Internet has become a such large part of our lives. A good understanding is needed to use this new tool most effectively. This topic would cover Internet address, ping program, stack & packets, internet infrastructure (NSP), routers & all basic components of Internet.
TCP/IP
Short for Transmission Control Protocol/Internet Protocol, the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks.
Internet Control Message Protocol (ICMP)
It is a Network protocol useful in Internet Protocol (IP) network management & administration .
It is used to report:-
1)Errors in the underlying communications network.
2)Availability of remote host.
3)Network congestion.
Protocol Stack :
A protocol stack is a series of related communication protocols that gives network connected machines with each other . Without it a network would be unusable.
Packet
A packet the term used to describe a unit of data being sent across a network. Typical length packet is kilobyte or a thousand characters. A large message may be divided into thousands of individual packet.
Internet Infrastructure
All the hardware & services required to make this web page appear in your browser, get to your desktop. All the underlying technologies that are unseen, but make the internet go.
It consists top 5 areas:-
1)Data Centers.
2)Network Connectivity.
3)computer Equipment.
4)Storage Services.
5)Server Application
CONCLUSION :
Thus we have studied components of Internet and a view of how it works.
