Protocols and DNS

  

      I've learned some  types of protocols , namely  Internet Protocol,Transmission Control Protocol ,User Data gram Protocol ,File Transfer Protocol   ,Simple Mail Transfer Protocol ,and Hypertext Transfer  Protocol .Each protocol work on a specific task and time and  sometimes with other type of protocol. 

    I learned that when I am using computer I am not actually  the only one who control it.There are Domain Name System who serve me what I want. Because of this I now understand why I need patience in searching for something.
