Now, lag in most cases is annoying as beep. OMG So that's where the LAG come's from?! What will happen to those poor connected clients? I'll tell you, They will LAG like hell. Now you and all you'r four brothers are all making a Skype call and simultaneously browsing YouTube, listening to your favorite hard-style ).

Imagine you'r the host and you'r playing COD on internet connection. Once again i want to bring back those old memories of you playing Call of duty MW3, or any other online game. You still want to send something, But data loss is acceptable. So that's where UDP comes in the picture. I'll go ahead and assume that many of you guys use skype, right? What will happen to your conversation if the computers contently check everything. What happens when you use TCP? Well, every time the client sends something (when a bullet is fired, when you move) the host will confirm it by checking back at the client. Imagine yourself playing the popular game call of duty MW3. This protocol is used when you don't actually care about those few bits that were lost in the process of sending/receiving. So TCP basically makes sure ALL data was received! If it wasn't, the computer will send those bits again. So in order to verify that, TCP sends a conformation to you'r computer telling that the e-mail was complete. When we are sending an e -mail to someone we want the e-mail to arrive with the same text as the original. This protocol is used when you want to send something over the internet and you want to make sure absolutely NO bits are lost. This is the most common one you''ll come across. The most famous protocol is the IP - protocol. Protocols 'say' what can- and can't be done. In our case, the rules are checked by protocols. These rules are usually checked by the police. There are certain rules just like driving to fast or ignoring a red traffic light. Welcome back My sleepless army of young hackers,Įveryone uses internet, right? So for this tutorial, i'll start with the basics and slowly we'll get to the UPD Protocol.
