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.
