Alternatives
The table below shows what alternative pieces of hardware I could use instead of the ones I am currently using.
Software
Software is written programs or rules that refer to the operation of a computer system that are stored in read or write memory. It is primarily used for digitally stored data such as computer programs and other information that are read and written by computers. Software is programs that are used to direct the operations in a computer.
The two paragraphs below explain the two main types of software, they are:
Operating Software (O.S)
Operating software forms the basis of additional programs and creates an interface between the software and the computer. Operating software basically runs your computer. It is the most inpo5rtant piece of software in your computer. Operating software is software that consists of data and programs that run on a computer. It manages computer hardware and provides common services for the execution for various types of application software.
Application Software
Application software is software designed to help the user perform single or multiple related specific tasks. Some examples of these are word processors, spread sheets, database applications and media players.
The two points below explain the two main types of operating software, they are:
- CLI – this is short for command line interface.
- GUI – this is short for graphical user interface.
The operating software I used
The operating software I used in this task is called windows seven. It is the latest operating software made by Microsoft. It works on any type of computer. This includes laptops, netbooks etc. It shows me exactly what I was doing and I found it very easy to use. I found it very comfortable to use.
Differences if I used a different type of operating software.
If I used an older type of operating software such as windows 98, then the layout and design of the software will be different. It would be a bit difficult to use because it does not have all the advanced functions like the operating software I am currently using.
What would happen if I used CLI instead of GUI?
If I used CLI then it will be very difficult for me to do this task. This is because it doesn’t have any graphics pictures or icons. Also I do not know any commands that need to be entered. And it will take me a long time to learn these. It would be hard to display my work because it works be entering commands and not by using the mouse to click on icons etc.
Application Software
The application software that I used in this task is:
Microsoft word
Microsoft publisher
Internet explorer
Paint
The following table states what application software I used in this task. Alongside with this it states the price of it, its advantages & disadvantages and its main functions.
Alternatives
The following table shows what alternatives I can use for the application software I used.
Mozilla Firefox after it has loaded a webpage
Input
The following table states the input devices that I have used and errors that can be made from it and how to correct errors.
Keyboard
To detect errors in my work I done a spell and grammar check. I also checked it myself and got others to proof read it for mistakes.
I corrected the errors by retyping out the words that I spelt wrong using a dictionary.
When typing I made sure that I typed correctly and I used a dictionary to help type words that I did not know the spelling of.
Mouse
To detect any errors I checked what program I had opened up. I corrected errors by checking what icon I am going to click on before I selected it. And if I selected a wrong icon I closed it and opened up the right one.
In my work I made sure that the buttons in my work were placed with spaces in between so that the buttons weren’t too close. This makes it a less chance of clicking on other buttons by accident.
Scanner
When my worked had been scanned I looked a preview at it to see it had been scanned properly.
I done a pre-scan of a document to check that the document I scanned was the right way round. I also made sure that all the wires were connected properly.
I made sure that I scanned my work properly before putting it into my work.
Effects of Inaccurate Data
The table below shows the effect of inaccurate data.
The best method of checking the accuracy of data is to do a spell and grammar checks on the computer. This is because the computer is more accurate than humans. Also you could do a proof check yourself and also tell others to do it for you.
ValidationValidation is to make sure that all the information is valid and correct. It is important because if you have inaccurate data then information can be wrong and a lot of mishaps can happen.
With different input methods there may be side effects that can affect the accuracy of the data.
Verification
Verification is how accurate something is and how truthful something is. One example of this is someone’s personal data. If one bit of their data is not accurate and up to date then this could cause problems. Take for example someone who is booking a ticket. If the person creating the ticket gets the name wrong then the name will be printed wrong on the ticket. When the person who booked the ticket takes it to the airport and the staff there look at the name on the passport and the name on the ticket they will see that it is wrong. Staff will then be suspicious of the person doing fraud. This will also be trouble for the flight company.
Output
The following table states the output devices that I used. It also states its advantages and disadvantages along with how it works and the best place to use it.
In my task I have used the best possible output devices. It affected my work by improving the picture quality. It also made it look more professional. I have used devices such as an TFT monitor and laser printer.
Conclusion
The system I use for this task I think is the right one. This is because it contains all the hardware that is needed. I think that it is good and has the requirements that Satia Tours will need. Also the system is easy to use. I didn’t need any extra hardware for this task, everything I needed was there.
