How Internet works?

The awesomeness of the Internet can't be captured by any single lecture or a video. There are a lot of hardwares, softwares, protocols, policies, devices, whole lot of human thinking that makes it possible to connect to any part of the world in just  fractions of a second.

Animation :TCP vis-a-vas UDP

TCP is a heavyweight, connection oriented Transport layer protocol.When a file or message send it will get delivered unless connections fails. If connection lost, the server will request the lost part. There is no corruption while there is transfer of message. The message will be in ordered way.Used for bigger segments. Examples of applications using TCP are World Wide Web (Apache TCP port 80), e-mail (SMTP TCP port 25 Postfix MTA), File Transfer Protocol (FTP port 21) and Secure Shell (Open SSH port 22) etc.
UDP is lightweight, connectionless Transport layer protocol.Once we send a data or message, we don't know if it'll get there, it could get lost on the way. There may be corruption on the way to the destination.The received message may or may not in ordered way.Used for smaller segments.Examples of applications using UDP are Domain Name System (DNS UDP port 53), streaming media applications such as IPTV or movies, Voice over IP (VoIP), Trivial File Transfer Protocol (TFTP) and online multiplayer games etc.
   Understand the two protocols through the animations below.

Animation:The journey of an E-Mail...

Technology has given us an instant means of sending letters i.e. E-mail. Whereas E-mail is fast but the hand written traditional letters carry much-much affection. I still remember those days when I was in school, watching my parents waiting for a letter from our loved ones. While Email gives you instant gratification, still the real love is carried by the traditional hand written letters with the touch and the fragrance of the real loved ones.Both the ways are great ways of communication.The post offices facilitates the journey of our traditional letters.Have we ever wondered how an E-mail travels through Internet. The protocols that facilitates this are the SMTP(Simple mail transfer protocol) and the POP(Post Office Protocol).
