Study Notes
TCP/IP Network Structure
- The Transport Layer is responsible for providing reliable data transfer between devices, including error detection and correction.
- The Link Layer is responsible for providing error-free transfer of data frames between two devices on the same network.
Regulatory Organizations
- The Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for regulating the internet's domain name system and IP address allocation.
- The US Department of Commerce is primarily responsible for overseeing ICANN.
Protocols
- The primary function of the User Datagram Protocol (UDP) is to provide best-effort, connectionless data transfer between devices, with no guarantee of delivery or order of packets.
- HTTP stands for HyperText Transfer Protocol, which is a protocol used for transferring data, including web pages, over the internet.
Internet Governance
- The Internet Engineering Task Force (IETF) is responsible for developing and maintaining the internet's technical infrastructure, including setting standards for internet protocols.
- The World Wide Web Consortium (W3C) is primarily responsible for developing and maintaining standards for the World Wide Web, including HTML, CSS, and XML.
Packet Delivery
- The Transport Layer is responsible for end-to-end (un)reliable delivery of TCP or UDP packets.
