Study Notes
How the Internet Works
- Any computer or hardware that can send and receive data using correct networking protocols can be part of the Internet
- The Internet's distributed nature makes it resilient, allowing computers, servers, and networking hardware to connect and disconnect without impacting its functionality
- The fundamental concepts of the Internet are packets and protocols
- Packets are small segments of a larger message containing data and packet header information
- Packets are sent across the Internet using packet switching, allowing for independent processing by intermediary routers and switches
- Protocols are standardized ways of formatting data and performing actions to enable communication between different devices
- Different types of hardware and infrastructure make the Internet work, including routers, switches, and web servers
- Routers forward packets to different computer networks based on their destination
- Switches connect devices on a single network and use packet switching to forward packets to the correct devices
- Web servers are specialized high-powered computers that store and serve content to users and perform important tasks to keep the Internet running
- The process of accessing a website involves sending data packets over the Internet, which are then received and interpreted by the user's device
- Specific steps in this process include DNS queries to find the website's IP address and the interpretation of data packets by the user's browser
