Which tool should be used?, Desoldering iron to heat the lead., Side cutting pliers to remove extra wires., Philips screwdriver to tighten components., Long – nose pliers to hold and bend the lead, 13-17. A school computer room was built beside a workshop that uses heavy electrical tools. Every time the machines are turned on, students experience slow loading and lost connections during online activities. The ICT teacher asks you to recommend a better cabling setup without rebuilding the entire network. What should you suggest?, Upgrade router bandwidth settings to allow faster transmission during busy hours., Add more patch panels so computers connect through additional network pathways., Extend cable distance farther away using longer unshielded twisted pair connections., Replace existing cables with shielded twisted pair connected using properly grounded ends., 18-22. During a network setup, Arkin was asked to terminate a UTP cable for connecting a computer to a router. He must select a wiring scheme to follow. Which wiring scheme BEST ensures proper connectivity for this straight-through connection?, Use T568A wiring scheme because it defines proper pin order for RJ-45 connectors., Use T568B wiring scheme because it defines proper pin order for RJ-45 connectors., Ensure the cable follows a standard wiring scheme to maintain compatibility between devices., Verify both ends use the same wiring scheme for a straight – through cable connection., Who developed the LAN technology that defines a system for connecting computers?, Robert Metcalfe, Robert Meyer, Robert Moore, Robert Murphy, What is another name for Ethernet Cabling?, LAN Cabling, Coaxial Networking, Fiber – Optic Cabling, Wireless Networking, Cristian wants to connect a computer to a router in the school lab.
