The different LCD technology used depend on cost and if you require true colour reproduction or high screen refresh rates are essential. Larger or ultra wide-screen monitors allow you to compare two documents on-screen. Monitors are normally measured diagonally in inches - typically 22, 24 or 27 inches. Most modern monitors use some form of Liquid Crystal Display (LCD) technology. The monitor is the computer's display screen.

You can also use external plug-ins, such as USB memory sticks and portable external hard drives, to supplement your computer's storage requirements. Even with a price premium for a SSD, given the performance advantage vs the overall cost of a typical desktop or laptop, in most cases including a SSD is the best approach. Although SSD can offer significant performance advantages, the cost per GB of storage can be two or three times more expensive for the same storage capacity. These drives are silent because they have no moving parts and are five to eight times faster than the standard magnetic hard disk drives used in most desktop computers. Some new laptops and specialist performance computers come with solid state drives (SSD). A typical office computer will have at least 500GB of hard disk space. The hard disk stores the data you create in your business, as well as the programs you use. To use multiple modern software applications effectively, you should have at least 4 gigabytes (GB) of RAM and preferably 8 GB or above for more memory intense software applications, such as design, photography or video editing. Your computer should have enough memory to make the most of the processor speed.

Generally, the more RAM you have, the better your computer will run when using several programs at once. The processor uses memory to run programs. More CPU cores and higher speeds improve processing throughput and therefore the perceived speed of the computer. You should buy the fastest processor you can afford, but dual or quad-core processors running at speeds of 2 GHz or above will normally be enough for most business functions, eg word processing, spreadsheets and some multimedia. The higher the GHz, the faster the computer will run.

Processors are usually differentiated by speed, measured in gigahertz (GHz).

The processor is the driver of the computer. When you buy PC hardware, you need to decide what the specification of these key components should be. The cost of hardware depends on its specification, which in turn is determined by some key components. PC hardware, such as a desktop computer, is the most common type of IT hardware purchased by a small business.
