Input  

1) Input is important to computer system because input is the means by which     a computer receives information from the outside world. Information that is from a non computer based source can only be transferred into the computer by input. 

Keyboard - allows you to enter numeric and alphabetic data into the computer

Mouse – controls movement of the cursor or pointer on a display screen

Gaming controllers – device that allows you to play the game using more realistic controls  

 3) Keyboard 

Enables you to type what you want at a faster rate, rather than using an on screen keyboard 

Disadvantage:May result in the cause of several injuries such as CTS    

Output  

1) Output is important to computer system because output is the means by which a computer sends information from either computer to computer/device or from computer to hardcopy. Information that is from a computer based source can only be transferred or made into a non-computer source by output. 

2) Examples of input devices are:

Display monitor – a device that projects a visual image of what is going on in the computer

Printer – prints text or illustrations on paper

Speaker – converts electrical signals loud enough to be heard at a distance

 3) Display monitor

Allows you to see what you are inputting into the computer system 

Disadvantages: May result in the cause of injuries such as Eye Strain 

Process 

1) The process is a set of instructions that are made by inputting data into the computer system then need to be executed for the computer to open windows, start programs, etc 

2) Process devices include:

Software programs – Allows inputs to be processed

CPU – Where all inputs are converted into output signals.

3) The advantage of a CPU is that it allows for fast processing of different inputs to be carried out as an output. CPU’s can also be upgraded to process faster. A disadvantage is that slower CPU’s take longer to process.

Storage

Storage  

1) Storage is important as is retains digital data used for computing. When transferring images or videos from a camera into a computer, the data has to be stored so that you can go back later and look at the data. That is one of the reasons why storage is important for computing systems.

3) Hard disk

Advantages:

You can save any data and access it whenever you want to on your computer

 Disadvantages:

There is a limit to how much can be saved into it and also it is stuck in the one computer, the data cant be accessed by another computer
