The reception area has one Receptionist on duty responsible for dealing with visitors, accepting and arranging deliveries, taking incoming telephone calls, and carrying out some general administration duties. There are three Architects and each has their own office where they create architectural drawings and revive architectural services for the company’s clients. The Office Manager has an office and is responsible for the diaries of the three Architects, allocating clients to individual Architects, overseeing the activities of the whole office plus liaising directly with clients.

There are three staff members in the single-roomed administration office; one Marketing Manager who is responsible for advertising and marketing the business and two Administration Assistants who are responsible for all general administration duties for the firm. The data network installed in the office will provide Internet facilities throughout the office plus an intranet that will provide services such as access to client information, email facilities and file storage. An extranet will also be created to allow for company employees to work remotely and for clients to view documents directly.

The network must include facilities that allow for the storage and transmission of large files such as architectural drawings. Your role is to write a report outlining the options for the firm of architects in setting up their data network including details of how the intranet and extranet arrives will be provided. The detail of your report is given in the tasks below, but in general, you should provide a range of options and make recommendations as to which you think is the best option.
