First and foremost, a server is a computer designed to store, manage, process and send data. A server can help stabilize a network, boost data processing efficiency, support security and data backup features, and allow information to flow quickly and securely around the network.

There is no definitive question that will help in determining whether an office needs a server. Instead, the answer lies within several questions regarding the network and the office needs. For example, an office with less than five employees may not require a server if all the staff members do is share files, access the Internet, and send e-mail. An office with more than five employees who share files is more likely to require a server.

Additionally, applications or systems such as e-mail servers, security systems, database services, e-commerce solutions, or a company Web site will typically necessitate a server.

If you decide that adding a server to your network is appropriate for your office, keep in mind that server requirements will depend on what you intend on using the server for. Before beginning a search for a new server, take note of the duties the server will need to perform. Keep in mind, most small and medium business generally use a server for file/print functions and Web services. Once the office's needs are fully assessed, shop around for a server that best fits your needs and budget.
