  • A network is simply a collection of computers or similar devices that can communicate over a transmission medium.
  • To actually send any data from one computer to another we need to make use of a network protocol. A network protocol is a set of common rules that defines how data should be sent.
  • Without a common suite like TCP/IP, the internet would not be possible.
  • ...12 more annotations...
  • The goal was to create a network that didn’t depend on other parts of the network to operate- one of the key features of TCP/IP.
  • Instead of one computer having authority over others, computers generally operate as equals.
  • This ambitious project was initially named ARPANET after the Defense Department’s Advanced Research Projects Agency (ARPA).
  • How does the computer know where to send each packet of data if multiple applications are running?
  • UDP is great for broadcasting data- such as streaming radio music.
  • ach card has a unique physical address that is set at the factory, and can’t be changed. Essentially this is an identifier for the computer it is installed on.
  • Instead of looking at every bit of data on the internet, logical addressing allows for computers to just look at data on a home network or subnet.
  • A router is a device used to read logical addressing information, and to direct the data to the appropriate destination.
  • TCP/IP includes protocols that tell routers how to find a path through the network.
  • Instead of having to remember an IP address, name resolution allows you to remember Google’s name.
  • This handy service is accomplished on name servers, which are just computers that store tables that translate domain names to and from IP addresses.
  • just ask them why ARPANET designers pressed for a decentralized protocol suite!
