Hardware
Hardware is a part of computer which can be seen and touched.
Types of hardware
There are 4 main types of hardware as shown below:
Input: A hardware which is used to put data.
Process: Turns input data into different type of data.
Storage: A hardware which keeps data safe.
Output: Takes out the input data from a computer.
The list below shows which hardware’s I used:
Input: keyboard, mouse and scanner.
Process: 3.0 GHZ processor.
Storage: 512 MB RAM, USB, 80 GB SATA Hard disk.
Output: monitor and printer.
This table shows which hardware’s I used to complete my coursework.
Alternatives
This table shows the alternatives of the table above
Software
Software is something which can’t be touched physically but it can be seen on the computer.
There are two main types of software’s: Operating software and application software as shown below.
Operating Software (O.S)
It shares computer system resources between the user and the application program they can run.
Application Software
Application software is designed to help the perform a particular task
There are two main types of software: CLI and GUI as shown below.

Operating Software (O.S)
It shares computer system resources between the user and the application program they can run.
Application Software
Application software is designed to help the perform a particular task
There are two main types of software: CLI and GUI as shown below.
- CLI –Command Line Interface
- GUI – Graphical User Interface
Operating software I used and why?
The operating software I used was GUI (Graphical User Interface) and the version was Windows 7.
If I had used Microsoft 98 or any other old version then my computer would probably work so slowly. Also some applications like Microsoft office Word won’t work properly because Microsoft 98 won’t be able to cope with the more Microsoft.
If I had used CLI (Command Line Interface) it would have been much difficult for me and it would have taken me so much time to do my work because I would have to learn so much commands. Another disadvantage is that I don’t know how to use CLI at all so it would have also taken me a long time to learn how to use it.
Application Software
These are the applications I used.
Microsoft Publisher
Microsoft Word
Paint
Internet Explorer
This table shows all the applications I used to complete my coursework
Alternatives
This table show the alternatives of the table above
Microsoft Publisher
It is used for creating mainly websites.
Microsoft Word
It is used for typing in any kind of information.
Internet Explorer
It is used for getting information.

Paint
It is used for creating pictures, drawings, logo E.T.C
Input
These are the input devices I used to make my work easy.
Keyboard
I detected errors in my work by using the spelling and grammar checker to check any spelling mistakes and any punctuation mistakes. To correct the errors in my work I would use the proof reader to correct mistakes that are done in my work. To prevent errors from happening, I typed a bit slower and much more carefully and I carried on looking at the screen to see if there were any mistakes I made.
Mouse
I detected errors in my work by checking manually if I made any clicking mistakes. To correct the errors in my work I would check manually and make sure that I would click the right thing if something unwanted had been clicked by going back and clicking the right thing. To prevent errors from happening in my work I would make sure that I would buy a mouse pad so that the mouse doesn’t slip and so the wrong thing doesn’t be clicked.
Scanner
I detected errors in my work by checking manually if all the information has been scanned and also that it is the right way round but not upside down. To correct the errors in my work I would check manually and make sure that if the data is scanned upside down than I would delete that data and I would than scan the data again by moving the data on the scanner the other way round. To prevent errors from happening in my work I would make sure that the data is the right way round in the first place and also make sure that no part of it is covered up.
Effects of Inaccurate Data
Inaccurate data will affect the system in many ways.
The best way to stop all the problems is to keep on checking if you have made mistakes. This way all your mistakes will be sorted out. And there won’t be any inaccurate data
Validation
Validation is to make sure that data which is being entered should be reasonable and allowable meaning that it is something possible but it doesn’t have to be correct.
There are a few different types of validations to help reduce the number of errors made by a user:
Type check, range check, picture or format check, check digit, field length checks etc.
Verification
The validation can be used to make sure that when a user types data in the computer and if there are any errors made in the typing then they are reduced.
For example if a database was going to be made with mistakes like if a 1993 date of birth was typed and was not true, the computer will not take it as an error if was programmed to let in anything between 1990 and1994. So the results would be incorrect and full of mistakes. This could also be known as Garbage In, Garbage out (GIGO). So that is why validations are important to help make sure that the user knows if there are any errors that have been made when typing data into the computer but it does not help in telling if the data is true or false.
Output
This table shows the outputs I used.
After I looked at the different output devices, my work has not really affected me in any sort of way. However I have used the best possible outputs devices for my task. which helped me a little bit.
Conclusion
The system that I used for this task was the right one because it has all the applications and programs that I needed to do my work successfully and correct with no mistakes or errors.
There is one more hardware that was used for the company. It is shown below.
