Setting Up a Basic IT System

2. Core Components

At the heart of your IT system will lie a number of core components.

Choose them carefully to ensure you build a system which fits your requirements.

2.1 Computers are the workhorses in your business.

• You may wish to give each employee in your business their own computer.
• Desktop computers are cost-effective, but laptops are more flexible. For instance, employees can use them to work from home. See Remote working.
• Even the cheapest PCs can run basic office software.
• Pay attention to accessories like keyboards, mice and monitors. Ensure they are comfortable to use and get the largest monitors you can afford.

2.2 A network allows you to connect your computers together.

• Most businesses with more than one computer will benefit from a network.
• Information and documents can be easily shared.
• See Networking your business.

2.3 An Internet connection allows you to get online.

• A basic broadband connection (also called ADSL) uses a telephone line to connect you to the Internet. This offers a cost-effective, fast connection.
• Other types of Internet connection are available. These can be faster and more reliable. If the Internet is central to your business, ask your IT supplier to advise on connection options.
• You can share your Internet connection through a network.

2.4 A server sits at the centre of your computer network.

• Servers provide a central place to store data and can improve network performance.
• It can be tricky to set up a server if you are not an IT expert.
• If you choose not to invest in a server initially, plan for the possibility as your network grows.
