1. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. Looking at a particular floor in a particular building‚ all the devices connect to either a single Ethernet switch or single wireless access point‚ both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN? C. All Ethernet user devices can be up to 100 meters away (but no farther)‚ while WLAN devices must typically be

How VLAN’s work Types of VLAN’s Types of Connections Conclusion Reference links Introduction A Local Area Network (LAN) was originally defined as a network of computers located within the same area. Today‚ Local Area Networks are defined as a single broadcast domain. This means that if a user broadcasts information on his/her LAN‚ the broadcast will be received by every other user on the LAN. Broadcasts are prevented from leaving a LAN by using a

PROJECT 802 LAN STANDARDS The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet‚ 802.11 Wi-Fi‚ 802.15 Bluetooth/ZigBee‚ and 802.16. All the 802.11 specifications use the Ethernet protocol and Carrier Sense Multiple Access with Collision Avoidance

Introduction: Wi-Fi‚ an acronym for "Wireless Fidelity"‚ is a set of product compatibility standards for Wireless Local Area Networks (WLAN) based on the IEEE 802.11 specifications. Wi-Fi was intended to be used for mobile devices and LANs‚ but is now often used for Internet access. It enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point. Wireless Fidelity is the wireless
