Hardware is the physical part of the computer which you can actually touch. Software on the other hand is the part of the computer that you cannot touch. There are many different examples of hardware within a computer system including   Keyboards Printers   Scanners Monitors Disk drives   Computer towers When making my logo their where many different hardware that I used when making my logo. These include input, output and processing devises. The input device I used to make my logo was a keyboard. A keyboard is the main input devise attached to the computer. It allows you to enter text and numbers that will appear on the computer screen. A keyboard is made up of keys that are separate (as you can see in the picture below). These keys represent numbers and letter of the alphabet.

It will also help my logo look more professional if I type the name of the health centre. Another advantage for using a keyboard is that it is simple and easy to use and I know how to use it. I could not find any disadvantages for using a keyboard when making my logo, Id card, database or user manual however if you are typing up a long piece of work it could damage you back if you use a keyboard for too long. Another advantage for using the keyboard when making my database and my user manual is that it allows me to type in the information I want to appear on the screen. Another input device I used when making my logo was a mouse. This is a hand operated devise that allows you to control the curser that appears on the screen. It also allows you to move things and to click on things on the computer screen. On the bottom of the mouse of most mousse is a ball that rolls when you move it.
