   * Networking protocols define rules and conventions for communication between network devices 
   * Developed network protocols in "layers"
      * each layer of protocols responsible for defining communication between a certain network piece
   * _protocol suite_ - a combination of different protocols for each layer
      * referred to as a _TCP/IP stack_

   * _Internet Society (ISOC)_
      * guides future of internet by overseeing Internet standards, public policy, education, and training
      * members are corporations, international and gov. organizations, and individuals (ex. IAB, IETF)
   * _Internet Corporation for Assigned Names and Numbers (ICANN)_
      * assigns Internet addresses
      * run by an international board of directors and funded by the Internet community
   * _Internet Activities Board (IAB)_
      *defines the architecture for the Internet
      *oversees the Internet's protocols (TCP/IP)
   * _Internet Engineering Task Force (IETF)_
      * 70 informal committees responsible for keeping the Internet up and running every day
      * IAB supervises the IETF

   * __Request for Comments(RFC)__  document the TCP/IP protocols
      * the RFC editors are a small group that works for ISOC but anyone can write an RFC
      * RFC categories:
         * _Standard_ - approved technical standard, Proposed Standard -> Draft Standard -> Standard
         * _Best Current Practices (BCP)_ - guidelines and recommendations, RFC 4107 "Guidelines for Cryptographic Key Management"
         * _Experimental_ - part of a research or development project, RFC 5335 "Internationalized Email Headers"
         * _Historic_ - refers most RFCs are former standards that are now obsolete
         * _Informational (FYI)_ - provides general information, RFC 4677 "The Tao of IETF - A Novices Guide to the Internet Engineering Task Force"
   * _intranet_ - a private network within an organization
   * _extranet_ - a part of an intranet that is shared with people outside your organization (ex. customers, suppliers)
   * _Virtual Private Networks (VPN)_ - private network that runs over public facilities, such as the Internet
      * secure bc it encrypts data before sending it, and uses special tunneling and security protocols on the public network
