Introduction to Networks
- The Internet is a vast network of billions of connected computing devices.
- These devices are called "hosts" and run network applications at the "edge" of the Internet.
- Network applications include web browsing, streaming video, emailing, social media, and more.
- Packet switches like routers and switches forward packets of data between devices.
- Communication links like fiber, copper, radio, and satellite carry data with varying bandwidths.
- A network is a collection of devices, routers, and links managed by an organization.
- "Fun" Internet-connected devices include smart home appliances, fitness trackers, security systems, vehicles, and more.
- The Internet is a "network of networks" connected by Internet Service Providers (ISPs).
- The Internet uses protocols to control the sending and receiving of messages, like HTTP (web), streaming video, Skype, TCP, IP, WiFi, 4G, and Ethernet.
- The Internet utilizes standards defined by the Internet Engineering Task Force (IETF) and documented as Request for Comments (RFCs).
- The Internet provides services to applications like the web, streaming video, multimedia, teleconferencing, and more.
- It acts as a programming interface enabling applications to communicate and utilize the network's transport capabilities.
- Protocols provide rules for communicating between devices over the Internet.
