- COutput-process-input
- DInput-Process-Output
- EInput-Plokess-Output
4Pick 1 incorrect characteristic of a computer system.
- ABased on processing data and producing information.
- BThey are electronic, so they're fast.
- CYou cannot make them do anything you tell it.
- DYou can make them do anything you tell it.
5A dedicated system is designed to do many things. Examples are a PC, a smart TV and a games console.
- AVerdadero
- BFalso
6An embedded system is something that forms part of an electrical device.
- AVerdadero
- BFalso
7A general purpose system is a computer that can be used to do many different things.
- AVerdadero
- BFalso
8Check the two true facts about reliability of computer
- AIt's how consistently they perform according to their specification.
- BIt isn't important that a computer is reliable because nothing will happen if it breaks.
- CA computer system that isn't reliable may lead to the theft of important personal data.
- DA computer system is only reliable if there are at least 2000 pictures of cute animals on it.
9Computer systems can be lethal if they are unreliable.
- AVerdadero
- BFalso
10Choose 4 reasons why a new system can fail to deliver what was intended.
- AA goat looked at it.
- BThe developers weren't given enough time.
- CExisting systems needed to be incorporated, but that was too complicated.
- DSomeone drank a coffee and drinking coffee breaks systems.
- EThere were too many interested groups involved, who all expected different things.
- FA mouse, like in Cinderella, tried to make it but he could only make dresses.
- GFew users or people commissioning the project understood what it was for, and the staff didn't want to use it.
11Which development method is this?
- AWaterfall Model:
This model is called the waterfall model because it develops systematically from one phase to another downwards, like a waterfall. In the waterfall model, a stage of the sequence can only be started if the previous stage is completed. - BPrototyping Method:
In this method a brief description of what is wanted, for a module, is got from the customer. The system is then coded and the user allowed to try it out. The customer then provides feedback and comments, and the software is redesigned to improve it. This is repeated until the it is satisfactory.
They then start on another module until the whole system is complete. - CMethod 3: Rapid Application Development (RAD)
This method can be used to make high quality code very quickly. It’s similar to the prototyping method, but uses tools to make the code. The tools are very expensive and take lots of training to be able to use properly and include; GUI interface builder where you can drag and drop items onto a screen, and the code behind them is created automatically. CASE tools (computer aided software engineering) which can create high quality code with the aid of a computer system.
