Biography: Internet, now that we can send a message, the difficult part is over. What we need to do is put things into our message in a certain way so that it makes sense on the other end. Letters that we send in the real world always have something in common - they are all written on paper and in a language understood by the sender and recipient. Apa Itu Internet , I have discussed earlier how important conventions are for networks to operate, and this important concept still applies to our message. All parts of Internet transfer messages are written in things called 'Packages', and the layout and contents of the 'package' are carried out in accordance with 'Internet Protocol' (IP). You don't need to know these terms, but you need to know that these simple messages are error-prone and simple. Apa Itu Internet , You can think of 'package' as an Internet equivalent of a sentence - for ongoing conversations, there will be many of them sent in two-way communication. Everyone who has played 'Chinese whispers' will know how messy ('broken') messages can get when they are sent among many agents to get from their origin to their destination. Computer networks are not that bad, but something is wrong, and it is necessary to automatically detect and correct problems when they do. Imagine you are trying to correct a spelling error in a letter. Apa Itu Internet, this is usually easy to do because there are far fewer words than the possibility of word combinations along the letters. You can see when the letter combination doesn't spell words ('error'), and then easily guess what the correct word is. Errors in messages on the Internet are fixed in a very similar way. Messages sent are made longer than they should, and extra space is used to "Internet" messages so to speak - if "conclude" does not match the error message has been found and the message must be resent. In fact, it is often possible to logically estimate what's wrong with a message without the need for retransmission. Detection and correction of errors will never be perfect, because the message and the "conclude" section can be coincidentally chaotic so that they incorrectly indicate there is nothing wrong. Apa Itu Internet , this theory is based on storing a large "addition" section so that this unfortunate possibility is so impossible that it can be safely ignored. Reliable message transfers on the Internet are done via 'TCP'. You may have heard the term 'TCP / IP': this is only a normal combination of 'IP' and 'TCP', and is used for almost all Internet communications. IP is fundamental to the Internet, but TCP is not - there are actually other 'protocols' that can be used that I will not discuss. When most people think of the 'Internet Address', they think of something like' Internet 'rather than '69 .60.115.116'. People relate to names more easily than numbers, so special computers that need to be accessed by humans are usually named ('domain names') using a system known as 'DNS' ('domain name system'). All Internet communication is still done using an IP address (remember '69 .60.115.116 'is an IP address). Therefore, the 'domain name' is translated to the IP address behind the screen, before the main communication begins. In essence, the process of finding a domain name is quite simple - this is the process of Apa Itu Internet by moving left through the name, following the interrogation path. This is best shown by example - Internet will be seen as follows.
