please help me with this:

The building will be used by one company that also has offices elsewhere in the U.S. The network will need to have 90 connections throughout the building (see diagram below) and four servers, plus whatever hubs, switches, routers, cable, etc. that you choose to use. You are to select the equipment you will use for the network. I have attached a list of possible equipment.

Calculate the total cost of your network design in the table provided

Additional Factors to Consider:

The company is considered to have moderate needs from their network (e.g. 100 Mbps met their needs at their previous location). However, the company is expanding which has the potential to increase their network needs.

You will need to include a direct connection to their other office in Atlanta.

Assume the computers that will be purchased for the building will have 10/100/1000Base-T Network Interface Cards (i.e. you do not need to include NIC cost in your estimates)

There will be an additional 20 laptops that need wireless access (these are primarily located on the first floor and will have built-in wireless-ac NICs)

The Cable Costs (including installation) listed on the equipment list is for one computer connection only (e.g. if you have 50 connections, you will need to have 50 wires)
