SECTION 3: INPUT - PROCESS - OUTPUT (IPO) (DESKTOP BOOK - pgs 18 - 26)
Computers use their own special language (Binary Code - made up of '0's' and '1's') to perform any task it is asked to do. The first step of the IPO is Input:
- Input - Takes an instruction from you (the user). This will be using an input device such as a 'Mouse' by clicking or a 'Keyboard' by typing.
The second step of the IPO is Processing:
- This step is where the Computer's Central Processing Unit (CPU) calculates and sorts the data (information) given from the input.
The last step of the IPO is Output:
- This step is the result/outcome of the processed data. This can be displayed visually using the 'Monitor', or as sound using 'Speakers', etc.
Section 4: MS WORD (DESKTOP BOOK - pgs 91 - 103)
The bar across the top of the Word application is known as the 'Ribbon'. This includes all the features used for creating a Word document.
'File', 'Home', 'Insert', etc. across the top of the Ribbon are called 'Tabs'.
'Clipboard', 'Font', 'Paragraph', etc. underneath the Ribbon are called 'Groups'.
The bar across the bottom of the Word application is called the 'Status Bar'. This is used for zooming in and out, indicating the page number and word count; and page viewing modes.
The large blank area of the Word document is called the 'Main Body of Text'.
The feature used for inputting the same text at the top of all document pages is called the 'Header'.
The feature used for inputting the same text at the bottom of all document pages is called the 'Footer'.
SECTION 5: MS POWERPOINT
MS Paint also has a 'Ribbon' bar at the top of the Paint application, which uses various 'Tabs' and 'Groups' of features.
The 'Status Bar' at the bottom of the application indicates the slide number, various slide view modes and also the zoom feature. Furthermore, as an additional feature, 'Notes' can be included for each slide as a reference during PowerPoint Presentations.
To format an image, select it within the slide page and use the various 'Picture Format' tools on the 'Tab' to change the image features.
To make your image(s) and text move/appear during a slide show presentation, select each one and use the features on the 'Animation' tab to make it move.
To make each slide appear in a unique way, use the 'Transitions' tab to select the type of change you would like your slideshow presentation to produce.
