It is important that data is entered correctly because accuracy is extremely important. If telephone numbers are entered incorrectly, this would mean that customers would be unable to contact the organisation if needed. This could be detrimental to the number of enquiries it would receive. This could be harmful to the amount of profit gained by the organisation, which could have been easily prevented if this human error was picked up earlier. It also makes the organisation become sloppy and unprofessional if problems like this are not spotted, and if work is not proof read before it goes to print.
I could check that the data has been correctly entered by proof reading everything several times, and getting an unconnected person to read it through to spot any errors. This would prevent any misunderstandings and confusion. I could also use the ‘Spelling and Grammar Checker’ which is on most of the Microsoft programmes, which could pick up lots of mistakes. But this does not pick up missed letters or missed words which would cause even more confusion. This can again be resolved by proof reading.
The choice of data entry method can affect speed and accuracy because typing is normally a very slow and tedious process which takes up a lot of time. This method of entry means that it is also easy to make a typing error, which not always be picked up upon, which is inaccurate. If a microphone was used, alongside a voice recognition programme, it would be a much quicker and efficient method of entering data. But this software is expensive to purchase but once up and running, it is easy to use for most people.

4. Hardware used (for input and output)
The hardware I used to make my system included
In the computers that I used, they all had a 40GB Hard Drive which means that the computer can store 40GB worth of programs and games for it to function properly. The Hard Drive stores all the computer’s information and protects it all when the computer has been turned off. The computers also had Pentium 4 Processors in them, which are microprocessors, which allows a much higher bandwidth than on computers with the old Pentium 3 Processors. It also has 256MB RAM, which allows the computer to do all the necessary tasks needed, when the computer is turned on. All these components are more than are actually needed, but they just allow the user have an easier time while carrying out tasks on the computer.

I decided to choose this hardware because it was the only option available to me in school. But the
