Desktop hardware, such as PCs, is the most common type of hardware purchase for a small business. The cost of hardware depends on its specification. This in turn is determined by some key components. When you buy desktop hardware you will need to decide what the specification of these key components should be.
The processor is the heart of a desktop PC. Processors are distinguished by their speed measured in Gigahertz (GHz). The higher the speed, the faster the PC will be. For normal office-based PC usage, it is not necessary to buy the fastest processor. A typical processor running at about 2 GHz delivers excellent performance for normal office functions.
Memory is used by the processor to run programs. Generally, the more random access memory (RAM) you have, the better the PC will run when using several programs at once. A typical office PC can run well with 512 megabytes (MB) of memory and this is a good minimum specification. Although if you are buying a new PC with Windows Vista, you will need at least 1 gigabytes (GB) of RAM.The hard disk is used to store the data that you create in your business as well as the programs that you use. Its capacity is much greater than the RAM. A typical office computer has at least 160 gigabytes (GB) of hard disk space, but if you intend to use a single desktop PC as the main storage location for all your business data then you will need more.
The monitor is the display screen. There are two types of monitor - flat screen or cathode ray tube (CRT). Flat screens are more expensive but are becoming more widely used as they use less desk space and generate less heat. Select at least a 17 inch monitor for desktop use.The keyboard and mouse usually come as part of a bundle but you may be able to select wireless devices that make desktops neater.There are alternative computers to conventional PCs available, such as Apple Macs, which have historically been used to support desktop publishing software. However, they now offer a comparable system for general office use
