1. An extensive telecommunications infrastructure is provided by a structured cabling system, which is a complete system of cabling and related components. This infrastructure is used for a variety of purposes, including phone service provision and data transmission across computer networks. It shouldn't be hardware-reliant. A structured cabling system is further defined in terms of ownership. At the termination of the service provider (SP), the structured cabling system starts. The demarcation point (demarc) or network interface device is at this location (NID). For instance, in the establishment of a telephone system, the SP provides one or more service lines (per customer requirements). At the line of demarcation, the SP joins the service lines. 1.1 Explain the significance of structured cabling and the advantages of structured cabling. (10) 1.2 As a network architecture, you are tasked with designing a network for a six-story office building, with each floor connecting 5 computers in 5 offices and having a wireless access point to connect wireless devices. Design a network plan for the building using your knowledge of structured cabling and various network devices, labeling all the hardware in devices and cabling. (20)
