Presentation transcript:

The Internet by Manny San Miguel Brief History of the Internet OSI Model 7 layer model OSI-TCP/IP Comparison IPv6 HTML5 Summary

Brief History of Internet 1969 - Arpanet was the first real network to run on packet switching packet switching technology (new at the time) 1971 - Email was first developed in 1971 by Ray Tomilson 1977 - First PC modem was introduced 1984 – The domain name system was created 1991 – First web page created

OSI Model 7 layer model 7 - Ensures network communication between Application programs 6 - Transforms data into form application can accept 5 - Interhost communication 4 - End-to-end connections and reliability 3 - Logical addressing path determination 2 - Physical addressing; network interface 1 - Media, signal and binary transmission

OSI-TCP/IP Comparison The main differences between the OSI architecture and that of TCP/IP relate to the layers above the transport layer (layer 4) and those at the network layer (layer 3). OSI has both, the session layer and the presentation layer, whereas TCP/IP combines both into an application layer. The requirement for a connectionless protocol also required TCP/IP to combine OSI’s physical layer and data link layer into a network level.

IPv6 A version of the Internet Protocol that is designed to succeed Internet Protocol version 4 IPv6 has a vastly larger address space than IPv4, results from the use of a 128-bit address, whereas IPv4 uses only 32 bits IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers Network security is integrated into the design of the IPv6 architecture

HTML5 HTML5 is currently under development, as the next major revision of the HTML standard. HTML5 is a standard for structuring and presenting content on the World Wide Web The new standard incorporates features like video playback and drag-and-drop that have been previously dependent on third-party browser plug-ins such as Adobe Flash and Microsoft Silverlight
