Using Hardware

I used very basic hardware in my system for the inputs, processors and outputs. I am going to explain the hardware, its advantages and disadvantages of using them and also the alternative hardware devices that I could have used.  

Backing Store: This consists of the disk drives used to store data when the power is switched off. They also include floppy disks, memory sticks etc.

Output Device: These include printers etc. They are used to provide output data in the form of printouts, screen displays, leaflets etc.

Input Device: These are used to get the data into the computer. They include scanners, microphones, keyboards etc.

CPU (central processing unit): The CPU is the brain of the computer which performs all of the processes that take place in the computer system.

Input Devices

Devices used and advantages

I have decided to use simple but necessary devices to buy and use for my company. This is due to the fact that my company’s main task is to store information, book holidays and to write to our customers, therefore we do not need any expensive or over the top devices as we simply do not need it and it only be a waste money. The input hardware devices I used is a mouse and a keyboard as not only do my staff not need any other input device but they would also have to take extra courses in order to learn the various input hardware devices. This would only be a waste of time. Entering data is very simple; the letters are big, bold, and clear and there’s a very little amount of things that could go wrong which are hardware based.

Alternative Devices and disadvantages

My alternate devices that I could possibly have used would have been; a device such as a microphone with voice recognition which inputs the words which are being said.

However the disadvantages of it are that the voice recognition is very inaccurate and a lot of typos occur due to the false reading. This means spending too much money when the same data could just be typed in. and a scanner could have been used to input some data.
