You have been asked by Champions, a local charity retail organization to install a network in its downtown office. It currently has seven PC's running Windows XP Home Edition. They are configured as follows: Pentium 4 at 3.0 GHz, 100-GB IDE hard drive, 512 MB of memory, floppy drive, CD-ROM, 64MB memory video card, 1 parallel port,1 serial port, and 1 usb 2.0 port. Champions' owners are not very concerned about security because the network will share only product inventory information, not information about customers. The owners have asked for a simple, inexpensive network solution that will not require the purchase of new software or personnel computers at this initial phase. Champions has volunteers run its stores, and the organization has a limited budget for this initial project. What type of network architure/model and topology would you recommend, and why? Champions is expected to receive a substantial donation in the near future. This donation enables it to double the size of its network to 14 PC's. What type of network architure and topology would you recommend once the organization receives this donation, and why? Be sure to explain in some detail the advantages and disadvantages of the network models that you recommend. What additional software and hardware upgrades would be required? Explain whether they should consider using a network operating system (NOS) and when it would be appropriate. Which NOS would you recommend given the organization's plans?
