TCPIP_1_LAN_WAN Transfer communication protocol.pptx

This is a presentation related to tcpip protocol. This protocol is used in networking concepts and socjet programming.

1. Networking with TCP/IP Overview for Interviews

2. AGENDA What is Network ? What is a Protocol ? Low  Level vs High Level Protocol. What is Protocol Suite ? Embedded Networking. Intra Circuit vs Inter Circuit Communication  ?

3. What is TCP/IP (not expansion) ? Evolution of TCP/IP . Goal & Beauty of TCP/IP. Topologies LAN WAN Internet

4. What is Network ? Network refers to the interconnection of two or more devices directly or indirectly to accomplish reliable communication using one or more protocols functioning between them. What is protocol ? Refers to a set of rules, regulations , checkpoints & sometimes standards to be followed for reliable communication.

5. Low level/bus protocol involves rules,regulation,checkpoints (logical aspect) & standards(physical aspect) as well. Examples: UART’S protocol,I2C,SPI,CAN,etc(wired protcols ), Phillips RC5 remote control protcol,Bluetooth,RF,Wifi,etc (wireless protocols)

6. High level protocols involve only rules , regulation & checkpoints (logical aspect). What is protocol suite ? Refers to set/collection/bunch/stack/layers of protocols (BUT NOT just ONE protocol) being used for communication between connected devices. Examples: TCP/IP,AUTOSAR etc

7. Embedded Networking Communication ,between two or more standalone embedded devices(inter-circuit) ,or between the CPU(s),or/and CPU(s) with certain peripheral components on the same embedded board(intra circuit) can be referred to as embedded networking. Wired & wireless protocol may be involved

8. What is TCP/IP ? The acronym TCP/IP which stands for Transmission Control Protocol/Internet Protocol refers to high level protocol suite created by IETF (Internet Engineering Task Force Organisation ) for distributed networking. Documents released by IETF are numbered and called as Request For Comments(RFC’s)

9. Evolution of TCP/IP . TCP/IP evolved from a result of an successful experiment done by an US department of defence named as ARPANET(Advance research project agency network) to have fault tolerant distributed network for computers in military units.

10. Goal of TCP/IP : Proprietary protocols were initially used. The idea of ARPANET was continued by IETF to create TCP/IP protocol suite to accomplish reliable communication irrespective of hardware make of connected computers & accessories Geographical positions of connected computers Topologies of the connected computers Platform(OS) used/or not between connected computers.

11. Beauty of TCP/IP: Though TCP/IP high level protocol suite emerged in early 70’s,and worked on top of limited available low level ,bus protocols during that era, still it has been adopting/migrating to work on top of numerous evolving low level/bus protocols (wired/wireless) untill now & will continue then with few changes possibly.

12. What are network topologies ? A topology is the layout of how a network communicates with different devices. Examples: star, bus,ring,mesh,hybrid,adhoc,infrastructure,wireless mesh Refer url https://www.youtube.com/watch?v=zbqrNg4C98U&t=60s

13. About Networking With TCP/IP Networking with TCP/IP can be divided into 3 LEARNING/JOB/EARNING AREAS namely: Network Administration(CCNA/CCNP/ MCITP,etc courses need to learned) Network Security(Ethical Hacking Courses need to learned) Network Programming (apt for vector embedded engineers,requires knowledge of C programming,OS concepts,Networking (BSD POSIX compliant socket )APIs for implementing communication between systems)

14. Network Types Depend on how large network are and how much of an area they cover geographically. LAN(Local Area Network ) is that which supports broadcast communication .What the transmitter send traverse through the medium/path unchanged/changed physically(signal & frame) before it reaches the receiver as it is. Connecting Device (DCE’s) which facillate communication on such network are repeater,hub,bridge,switch,router .

15. WAN(Wide Area Network) is that which supports point to point communication . What ever the transmitter sends may be changed as preferred physically(signal & frame) before reaching the receiver as it is. Connecting Devices(DCE’s) which facilitate communication on such network are Router,Gateway .

16. Interconnection of two or more LANs makes a WAN. Interconnection of two or more LANS/WANs using commercial communication service providers networks(ISPs) is what we call as INTERNET today. Connecting devices(DCE’s) such Modems,CSU /DSU are used to facilitate communication. Refer url : https://www.youtube.com/watch?v=4_zSIXb7tLQ
