This document defines network protocols and discusses TCP/IP. It defines a protocol as a set of rules that govern communication between connected computers. The main types of network protocols listed are TCP/IP, IPX/SPX, AppleTalk, and NetBIOS/NetBEUI. TCP/IP is described as the common protocol for Internet communication, consisting of TCP, UDP, IP, ICMP, and ARP which handle transmission control, user datagrams, internet addressing, error messages, and address resolution respectively.

Technology
1 of 9
Learning Outcomes 1. Define protocol and list all the main types of network protocol. 2. Core protocols of TCP/IP
What is PROTOCOL?  Define the set of rules that govern the communications between two computers connected to the network.  Roles: addressing and routing of messages, error detection and recovery, sequence and flow controls.  Terminologies: In order for two computers to talk to each other, they must be speaking the same language
Main types of network protocols • TCP/IP (for UNIX, Windows NT, Windows 95 and other platforms) – common network protocol for communication. • IPX/SPX(Internetwork Packet Exchange/Sequenced Packet Exchange) – Network Games • AppleTalk (for Macintosh computers) – communication protocol among Macintosh computer only. • NetBIOS/NetBEUI (for LAN Manager and Windows NT networks) – Network Basic Input Output System.
TCP/IP • TCP/IP is the communication protocol for communication between computers on the Internet. • TCP/IP = Transmission Control Protocol / Internet Protocol. • TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.
TCP/IP Model
TCP/IP Model (cont…) Notes: Transport Layer may have one of two names. 1. TCP protocol is being used, it is called a Segment 2. UDP protocol is being used, it is called a Datagram
Core protocols of TCP/IP • TCP (Transmission Control Protocol) communication between applications - delivery ensured. • UDP (User Datagram Protocol) simple communication between applications - delivery not sure. • is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). • IP (Internet Protocol) communication between computers • ICMP (Internet Control Message Protocol) for errors and statistics • ARP(Address Resolution Protocol) for resolution of network layer addresses into link layer addresses (searching within multiple addresses)

Topic 2.2 network protocol

  • 1.
  • 2. Learning Outcomes 1. Define protocol and list all the main types of network protocol. 2. Core protocols of TCP/IP
  • 3. What is PROTOCOL?  Define the set of rules that govern the communications between two computers connected to the network.  Roles: addressing and routing of messages, error detection and recovery, sequence and flow controls.  Terminologies: In order for two computers to talk to each other, they must be speaking the same language
  • 4. Main types of network protocols • TCP/IP (for UNIX, Windows NT, Windows 95 and other platforms) – common network protocol for communication. • IPX/SPX(Internetwork Packet Exchange/Sequenced Packet Exchange) – Network Games • AppleTalk (for Macintosh computers) – communication protocol among Macintosh computer only. • NetBIOS/NetBEUI (for LAN Manager and Windows NT networks) – Network Basic Input Output System.
  • 5. TCP/IP • TCP/IP is the communication protocol for communication between computers on the Internet. • TCP/IP = Transmission Control Protocol / Internet Protocol. • TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.
  • 7. TCP/IP Model (cont…) Notes: Transport Layer may have one of two names. 1. TCP protocol is being used, it is called a Segment 2. UDP protocol is being used, it is called a Datagram
  • 8. Core protocols of TCP/IP • TCP (Transmission Control Protocol) communication between applications - delivery ensured. • UDP (User Datagram Protocol) simple communication between applications - delivery not sure. • is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). • IP (Internet Protocol) communication between computers • ICMP (Internet Control Message Protocol) for errors and statistics • ARP(Address Resolution Protocol) for resolution of network layer addresses into link layer addresses (searching within multiple addresses)
