You are network technician for a small corporate network. An employee in the Support Office says his computer won't connect to the network. The IT manager suspects there is a bad patch cable in the networking closet. In this lab, your task is to find the bad patch cable and replace it with another Cat5e cable to see if that resolves the issue.
Inspect the activity lights on the switch to find the connection that is not lit or blinking.
Select the cable plugged into the connection and make note of the switch port number and the label on the patch panel.
Remove the bad cable and plug a new cable from the Shelf into the switch and the patch panel. (The new cable must be the same type of cable you just removed).
If the replacement is a good cable, the link light will be lit and blinking on the switch.
Go to the Support Office and open the Network and Sharing Center on the workstation to make sure the connection issue is resolved.

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
