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).

Increase Internet speed by 20%...

Microsoft reserves 20% of the bandwidth for their own purposes like Windows Updates, questioning the PC etc. That 20 % can be retrieved back for your use !

Understand ARP through animation

All interfaces in the network are identified by an IP address. The IP header encapsulated at the Network layer carries the ultimate source and destination IP addresses. However, for actual transmission, these IP datagrams are encapsulated in Data Link layer frames. The header in this layer carries the hardware addresses of the immediate source and destination.

TCP-IP and the DATA Flow....

In this post, I am not going to discuss in details about how a packet flow through network using TCP-IP layered protocol. My aim here is to share what I understand as to how TCP-IP protocol stack modifies a data and helps it to reach final destination. Please do comment and share, if my knowledge needs modification anywhere. Read on…..
