- 1. THE CONCEPT OF TCP/IP CHRIS STEVENS 2801639 -What is TCP/IP? -How Does TCP/IP Work? -Layers of Protocol -The Application Layer -The Transport Layer -The Internet Layer -The Network Layer -Encapsulation and Decapsulation -References http://www.rtkl.com/wp-content/uploads/2014/07/Blog-1-Header-Graphic_IoE.jpg
- 2. WHAT IS TCP/IP? TCP means Transmission Control Protocol IP means Internet Protocol Protocols are a set of rules used for communicating on networks or between to or more hosts http://atforum.com/news/wp-content/uploads/computers.jpg
- 3. HOW DOES TCP/IP WORK? TCP enables two hosts to establish a connection a connection and exchange steams of data IP protocol deals with only packets Packets are data which is divided into smaller pieces and is then transmitted individually (Beal,2014) http://baraknaamafinal.appspot.com/tcpip.jsp
- 4. LAYERS OF PROTOCOL There are four Layers of Protocol that coordinate together to make the network functional They are, -The Application Layer -The Transport Layer -The Internet Layer -The Network Access Layer http://en.wikipedia.org/wiki/Internet_protocol_suite#mediavi ewer/File:IP_stack_connections.svg
- 5. THE APPLICATION LAYER The application layer is the scope with which applications create user data and communicate this data to other applications. The application layer provides services such as -Mail Transfer Protocol -File Transfer -Web surfing -Web chat -Network data sharing -and Virtual terminations (Janessen,2014) http://education-portal.com/cimages/multimages/16/osi-application-layer.jpg
- 6. THE TRANSPORT LAYER http://www.chipkin.com/products/stack/bacnet-stack/ The Transport Layer preforms the host to host communications. It provides a channel for the communication need of the applications. (Wikipedia,2014) Provides the means to for data segments to be transported, It sends data to the internet layer when sending, and to the application layer when receiving.
- 7. THE INTERNET LAYER The Internet Layer is the IP, Internet Protocol Which controls: -Local Addressing, Ever machine has a IP address for addressing and Identifying -Routing, moving data across a series of interconnected networks. -Encapsulation, placing messages form higher layers into datagrams (TCP/IP Guide,2014)
- 8. THE NETWORK LAYER The Network Layer is the physical components of the network. What the data flows through. Some of the more common components are: -Assortment of Networking Wires -Network Hubs -Network Switches -Routers -Modems -Network Interface Cards http://www.itgeared.com/articles/1334-network-layer-3-osi-model/
- 9. ENCAPSULATION AND DECAPSULATION http://www.tcpipguide.com/free/t_IPDatagramEncapsulation.htm Encapsulation is converting the data into small packets with the necessary data the send to another user. The data included is: -Preamble used for bit synchronization -Start of Frame Delimiter -Destination Address -Length of Type -The Actual Data to send - And The Frame Check Sequence Decapsulation is the same process in reverse to open the data packet.
