TCP/IP Protocol Suite

A set of networking protocols that enables data transmission between computers.

TCP/IP Model

Defines a model that classifies four layers of data transmission categories: Application, Transport, Internet, and Data Link.

How TCP/IP Works

Divides data into packets, sends from sender, reassembles at receiver; based on client-server model where client sends request to server.

Application Layer

Performs the functions of the top three layers of the OSI model. Includes protocols like HTTP, TELNET, SMTP, and FTP.

Study Notes

TCP/IP Protocol Suite

  • The TCP/IP protocol suite facilitates data transmission between computers using Transmission Control Protocol (TCP) and Internet Protocol (IP)
  • TCP/IP specifies how data is packetized, addressed, transmitted, routed, and received, which provides end-to-end communication across networks
  • The TCP/IP suite is named after its core protocols, TCP and IP

TCP/IP Model

  • The TCP/IP model classifies four layers of data transmission:
  • Application
  • Transport
  • Internet
  • Data link
  • The model covers the journey of a data packet, from the initial request in a browser to delivery and rendering of a web server's response

How TCP/IP Works

  • Data is divided into packets based on a four-layered architecture when sent over the Internet
  • On the receiver's end, the order is reversed, and the data is reassembled
  • TCP/IP follows a client-server model, where a client sends a service request to a server
  • Each client request in the TCP/IP model is unique

Application Layer

  • The application layer performs the functions of the OSI model's top three layers
  • The top three layers are Application, Presentation, and Session
  • Here are a few of the application layer protocols:
  • Hypertext Transfer Protocol (HTTP) enables access to data over the internet in plain text, audio, and video
  • TELNET establishes connections between local and remote computers
  • Simple Mail Transfer Protocol (SMTP) is a TCP/IP protocol for handling email
  • The File Transfer Protocol (FTP) is a standard internet protocol for transferring data

Host-to-Host/Transport Layer

  • The transport layer is similar to the OSI model's transport layer
  • This layer specifies how much data should be sent, when, and at what rate
  • The message from the application layer is built upon the transport layer
  • Timely and error-free data unit delivery, using error control, flow control, and segmentation in order to control reliability
  • Successful data transmission is acknowledged, and the next data is sent

Protocols Used in Transport Layer

  • Transmission Control Protocol (TCP) offers error-free and reliable communication
  • TCP features data segmentation and sequencing
  • It also has an acknowledgment feature and a flow control method
  • TCP uses three-way handshaking
  • User Datagram Protocol (UDP) does not have the features of TCP
  • Applications not requiring dependable transmission can use UDP
  • UDP is relatively cost-effective and connectionless, so there is no assurance the data will be delivered

Internet Layer

  • The main function is to send packets from the source computer to its destination, regardless of route
  • It provides a functional means to send variable-length data sequences between nodes across multiple networks
  • It does not guarantee reliable network layer protocol
  • Internet Protocol (IP) is charged with sending packets based on IP addresses in packet headers, and has two variations, IPv6 and IPv4
  • Address Resolution Protocol (ARP) is a protocol for resolving conflicts between computers by determining a host's hardware address from an IP address
  • ARP converts 32-bit addresses to 48-bit addresses and vice versa
  • ARP is needed as IPv4 addresses are 32 bits long, and MAC addresses are 48 bits long
  • This specifies physical data transmission over the network, handling transmissions between adjacent devices on the same network
  • It also determines how bits should be signaled by hardware devices interfacing with network media

Uses of TCP/IP Model

  • Communication protocols allow for data exchange, making the Internet possible
  • It is important in text communication with flow and error control
  • TCP/IP handles operations to ensure transitions are in order and error-free for text communication
  • Examples include: WhatsApp, Instagram, Google Chat, and iMessage
  • Internet banking is possible because of the reliability, efficiency, and security of the model
  • Used for online gaming and video streaming because of flexibility in transmission
  • A mass audience can see sports broadcasts due to connection-oriented and connectionless transmissions
  • Provides functions such as DNS, DHCP, and VPN, to use the internet without fear of losing privacy and integrity
