  1. 1. WHAT IT IS ????<br />
  2. 2. INFORMATION <br />AND <br />COMMUNICATION TECHNOLOGY (ICT) <br />FORM 4<br />Topic <br />3.0 Computer Network And Communication <br />Sub Topic <br />3.1 Basic Concepts Of Computer Networks<br /> And Communications <br />
  3. 3. NETWORK STANDARDS & PROTOCOLS<br />LESSON OBJECTIVES<br />
  4. 4. NETWORK STANDARDS<br />
  5. 5. COMMON NETWORK STANDARDS<br /> Network communications use a variety of standards to ensure that<br /> data travels correctly to its destination.<br />Network standards define guidelines that specify the way<br />computers access the medium to which they are attached.<br /> Guidelines describe The type of medium<br /> The speeds used on different types of<br /> networks.<br /> The type of physical cable / wireless <br /> technology used.<br />
  6. 6. COMMON NETWORK STANDARDS<br /> The well-known standards adopted by the<br />Institute of Electrical and Electronic <br /> Engineers (IEEE) are the 802 standards. <br /> Requirements for physical cabling<br /> and specify the way data is <br /> transmitted.<br />The ones we will get to know here are :<br />802.3 (Ethernet LAN)<br />802.7 (Broadband LAN)<br />802.8 (Fiber-Optic LAN And MAN)<br />802.11 (WIRELESS LAN)<br />
  7. 7. 80288<br />ETHERNET LAN (802.3)<br /> Ethernet refers to the physical cabling,<br />while the way data is transmitted through <br /> the cable is called Carrier Sense Multiple <br />Access / Collision Detection (CSMA/ CD). <br />
  8. 8. 80288<br />BROADBAND LAN (802.7)<br /> Provides specifications for the design<br /> installation<br /> testing needed for broadband <br /> transmissions. <br /> Broadband transmissions allow simultaneous multiple <br />transmissions or signals using different communications channels<br />at the same time.<br />
  9. 9. 80288<br />FIBER-OPTIC LAN AND MAN(802.8)<br /> Gives the recommendations for the configuration and testing of<br /> fiber-optic Local Area Networks (LAN) and Metropolitan Area<br /> Networks (MAN). <br />
  10. 10. 80288<br />WIRELESS LAN (802.11)<br /> Communication between a wireless computer or client <br /> and an access point or between two wireless computers or<br />clients. <br />
  11. 11. BRAIN TEST !!!!<br />80288<br />What is Networks Standards ?<br />There are four (4) types of Networks Standards.<br />Network Standards is guidelines that specify the way<br />computers access the medium to which they are attached.<br />Ethernet LAN (802.3)<br />Broadband LAN (802.7)<br />Fiber-Optic LAN & MAN (802.8)<br />WIreless LAN (802.11)<br />
  12. 12. PROTOCOLS<br />
  13. 13. 80288<br />PROTOCOLS<br /> Protocols provide the rules on how computers communicate.<br />How devices intercommunicate in a network environment. <br />
  14. 14. 80288<br />THE IMPORTANT OF PROTOCOLS<br /> Define how devices, applications or computers communicate in a<br /> network. <br /> When two computers on a network perform a single exchange of<br />data or information, they will be busy looking for the best <br /> communication process between them. <br /> Ensuring that the information bits or data packets are sent or <br /> received in a proper sequence. <br />
  15. 15. 80288<br />TYPES OF PROTOCOLS<br />Hypertext Transfer Protocol (HTTP)<br /> Simple Mail Transfer Protocol (SMTP)<br /> File Transfer Protocol (FTP)<br /> Transmission Control Protocol (TCP)<br /> Internet Protocol (IP)<br />
  16. 16. 80288<br />HYPERTEXT TRANSFER PROTOCOL (HTTP) <br /> To access, send and receive Hypertext Markup Language<br />files (HTML) files on the Internet. <br />
  17. 17. 80288<br />SIMPLE MAIL TRANSFER PROTOCOL (SMTP) <br /> Transferring e-mail between computers<br />
  18. 18. 80288<br />FILE TRANSFER PROTOCOL (FTP) <br /> Allowing files to be copied between devices. <br />
  19. 19. 80288<br />TRANSMISSION CONTROL PROTOCOL (TCP) <br /> Ensures the delivery of information packets across network. <br />
  20. 20. 80288<br />INTERNET PROTOCOL (IP) <br />Providing logical addressing called IP address to route<br /> information between networks. <br />
  21. 21. GROUP ACTIVITY<br />
  22. 22. 80288<br />QUESTION TRUE OR FALSE ! <br />Simple Mail Transfer Protocol (SMTP) is ensures the delivery of information packets across network. <br />X<br />√<br />File Transfer Protocol (FTP) is responsible for allowing files to be copied between devices. <br />Transmission Control Protocol (TCP) is responsible for <br />providing logical addressing called IP address to route information between networks. <br />X<br />Hypertext Transfer Protocol (HTTP) is used to access, send and receive Hypertext Markup Language files (HTML) files on the Internet. <br />√<br />Internet Protocol (IP) is used for transferring e-mail between computers. <br />X<br />Protocol is guidelines that specify the way computers access the medium to which they are attached. <br />X<br />
