Study Notes

The Internet: a "nuts and bolts" view

  • The Internet is a "network of networks" that interconnects multiple networks managed by different organizations through Internet Service Providers (ISPs).
  • It consists of end systems (hosts) that run network applications, packet switches (routers and switches), and communication links (fiber, copper, radio, satellite).

Internet Components

  • Hosts: end systems that run network applications at the Internet's "edge".
  • Packet switches: forward packets using routers and switches.
  • Communication links: fiber, copper, radio, and satellite connections.
  • Networks: collections of devices, routers, and links managed by an organization.

Internet Standards

  • Request for Comments (RFC): documents containing technical specifications and organizational notes for the Internet.
  • Internet Engineering Task Force (IETF): develops and maintains Internet standards.

Protocols

  • Control the sending and receiving of messages between devices.
  • Examples: human protocol (e.g., a conversation), computer network protocol (e.g., TCP/IP).

What is a Protocol?

  • A set of rules and formats that govern data exchange between devices.
  • Enables devices to communicate with each other and understand the messages being sent.
