the internet

Protocols:

Protocols are created by a worldwide group of volunteers who draft, revise, and publish protocols -- The Internet Engineering Task Force (IETF) -- who make decisions by rough consensus

Protocols:

  • HTTP - HyperText Transfer Protocol
     

  • DNS - short for Domain Name System, this system translates domain names (like example.com) to IP addresses (like 93.184.216.34)

Getting the data there:

  • IP - A number assigned to any item that is connected to the Internet.

  • Packets - Small chunks of information that have been carefully formed from larger chunks of information

Getting the data there:

  • Router - A type of computer that forwards data across a network
     
  • Network Redundancy - having multiple backups to ensure reliability during cases of high usage or failure -"fault tolerance"

Getting the data there:

What is the lowest cost to get from data from computer G to E?

TCP - Transmission Control Protocol - provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing.
