Study Notes
Introduction to Networks
- The Internet is a network of interconnected devices known as hosts, running network applications like web browsing, video streaming, and email.
- The Internet is comprised of various "nuts and bolts," including hosts (end systems), packet switches (routers and switches), communication links (physical connections like fiber, copper), and networks formed by collections of devices and links.
- The Internet is a network of networks, where interconnected Internet service providers (ISPs) are connected to each other, and protocols govern the sending and receiving of messages between devices.
- The Internet is a service infrastructure that provides various applications with a way to connect to and use its transport service.
- Examples of Internet-enabled services include: web browsing, streaming video, multimedia teleconferencing, email, games, e-commerce, social media, and inter-connected appliances.
- Protocols are rules and procedures that dictate how devices communicate with each other over a network.
- They ensure that data is formatted correctly, addressed properly, and transmitted efficiently.
- The Internet Engineering Task Force (IETF) develops and standardizes Internet protocols.
- The IETF publishes Request for Comments (RFCs) that document protocols, specifications, and best practices for Internet technologies.
- An example of an Internet protocol is HTTP (Hypertext Transfer Protocol), which governs the exchange of information between web browsers and web servers.
- The Internet is a global network of networks that enables communication and data exchange between billions of devices worldwide.
- The Internet provides a foundation for numerous services used by individuals, businesses, and governments.
- These services range from basic communication channels to complex applications that leverage the interconnected nature of the Internet to facilitate various functions.
