IT Group Project Presentation by: Abdurahim Idris Our Team: Abdulhalim, Abdurahim, Abdurahman, Adugna, Adisu, Yakub This presentation will cover key concepts in networking protocols, protocol suites, and network models. We'll explore the TCP/IP and OSI models, various protocols, and how they facilitate communication between devices on a network. by Abdurehim Idris Understanding Protocols Definition Network Protocol A protocol is a set of rules A network protocol is a set or some guideline followed of established rules that by every node of the dictate how to format, network for data transmit and receive data communication. so that computer network devices can communicate effectively. Importance Without protocols, different computers and other devices wouldn't be able to communicate with each other because they would essentially be speaking different languages. Protocol Details Device Identification How each computer and other devices will be identified (it's address). Routing What route the data will take to get to its destination (routing information). Error Handling How errors will be found and dealt with (error checking). Acknowledgment Whether each part of messages should be acknowledged as received correctly. Error Resolution What to do if it isn't received correctly. Data Formatting How the data is to be formatted. Sequencing How the data is to be sequenced (in what order is the data sent). Synchronization How the speed of the sender and receiver can be synchronized. Protocol Suite Protocol Suite is a group of related protocols which are especially designed for computer networks. Networking Facilitates communication between different devices on a network Common Language Ensures devices can understand each other Compatibility Allows different types of devices to interact seamlessly Common Protocols and Their Uses Acronym Protocol name Used for SMTP Simple Mail Transfer Sending Emails via the Protocol internet POP3 Post office Protocol Retrieving emails from version 3 email server IMAP Internet Message Access Allow emails to be protocol accessed using multiple email clients TCP Transmission Control Can be used for Protocol networking computers and communicating across the Internet UDP User Datagram Protocol Connectionless communication model with minimum of protocol mechanisms TCP/IP Model TCP/IP Model stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. 1 Application Layer 2 Transport Layer 3 Internet Layer 4 Network Interface Layer OSI Model OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. Application Layer 1 Allows access to network and services Presentation Layer 2 Translates, encrypts, and compresses data Session Layer 3 Maintains connection and controls session Transport Layer 4 Transmits data using protocols like TCP and UDP Network Layer 5 Decides physical path of data Data Link Layer 6 Defines format of data on the network Physical Layer 7 Transmits raw bit stream over physical medium Comparing TCP/IP and OSI Models TCP/IP Model OSI Model Application Layer Application Layer Transport Layer Presentation Layer Internet Layer Session Layer Network Interface Layer Transport Layer Network Layer Data Link Layer Physical Layer TCP/IP Packet Structure Data sent using TCP/IP is broken up into packets. Each packet of data consists of a small section of the data being sent along with a packet header. Sending Computer Recipient Computer The header contains details The header includes of the sending computer information about the recipient computer Packet Count Packet Number How many packets the data The number of this particular has been split into packet Once the recipient computer receives all the packets, it will use information in the header to reconstruct the data into original format. Network Layers and Protocols Summary OSI model TCP/IP Functionalities Device used Protocol Application layer Application layer Data generation HTTP, FTP, DNS Presentation Encryption SSL, TLS, FTP layer formatting Session layer Establish Gateway Various API Connection Sockets Transport layer Transport layer Delivering and Firewall TCP and UDP sequence of data Network layer Internet layer Routing to Router IP and IPsec destination Data link layer Network or link Local network Switch and layer hosts delivery bridge Physical layer Access to media Cable and NIC
