Presentation on Ethernet,

Wireless Ethernet and the IEEE

Present By Marco

Agenda

Introduction on Ethernet What is Wireless Ethernet? What is IEEE stand for ? Strength and weaknesses of Wired

Ethernet and Wireless Ethernet.

•What is Ethernet? Ethernet is a protocol that controls

the way data is transmitted over a local area network (LAN).

It uses wires (meaning it is not a wireless technology).

With Network card

Wire Ethernet +

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.

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.

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

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.

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.

Wire Ethernet

Wireless Ethernet

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.

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.
