1. Group 04 ( and Group 13 ) – From Lecture 04, Due Session 02

2. Agenda  Introduction on Ethernet  What is Wireless Ethernet?  What is IEEE stand for ?  Strength and weaknesses of Wired Ethernet and Wireless Ethernet.

3. What is Ethernet?  Ethernet is a protocol that controls the way data is transmitted over a local area network (LAN).protocol  It uses wires (meaning it is not a wireless technology). With Network card Wire Ethernet +

4. What is wireless Ethernet  A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and transmit data.

5. What is IEEE?  Stand For :Institute of Electrical and Electronics Engineers  Defines such wireless technologies as Bluetooth and WiFi  IEEE developed a set of network standards.  The standards establish an authoritative common language that defines quality and sets technical criteria.

6. What is IEEE (Continued )  IEEE 802.11 is standard for WLAN/WiFi  IEEE 802.3 standard for Ethernet  IEEE 802.15.1 standard for Bluetooth  ABGN

7. What is IEEE (Continued )  Institute of Electrical and Electronics Engineers Graduate Engineer Qualified Engineer Professional Engineer

8. Advantages of Wired Ethernet  Receiving fast information/Better performance  Inexpensive and it is cheap.  Transfer information swiftly compare to wireless net work.  Low cost  Much more secure than wireless network.

9. Disadvantages of Wired Ethernet  It is expensive  Inconvenience from moving around your house.  It may slow down the network if add more computer result in unexpected expense if run out of connection.

10. Wire Ethernet Wireless Ethernet

11. Advantages of Wireless Ethernet  Neat and Clean, no untidy cables.  It is Flexible to access within a limited range.  Setup - Those without a great deal of networking experience can set up a wireless network.

12. Disadvantages of Wireless Ethernet  High cost and expensive.  Reliability – if one major section breaks down (eg. Router), the whole network will be affected.  Significantly slower than a wired Ethernet.  The network can be less stable. Wireless reception may be impaired by a number of factors including large distances.
