GRADE 5 REVISION NOTES

On Windows Operating System, there are many useful tools which you can use that will improve the performance of the Computer in various ways. These are found in the 'Windows Accessories' file and the 'Windows Administrative Tools' file also.

Under the 'Window Accessories' file, there are many different types of applications; such as design software like 'Paint' and 'Paint 3D'; media software like 'Windows Media Player' and editing software like 'Snipping Tool' and 'Steps Recorder'.

Word processing software such as 'Notepad' and 'Wordpad' are useful too, in addition to 'Sticky Notes'.

Under the 'Windows Administrative Tools' file, there are applications such as 'Defragment and Optimise Drives' and 'Disk Clean-up' to help improve the performance of the Computer's speed and storage capacity; and other system management tools which support the use of managing input and output devices such as printers and scanners.

Below demonstrates the features of 'Notepad', 'Sticky Notes' and 'Wordpad' and how they can be used.

Below demonstrates the features of the 'Disk Clean-up' and 'Defragment and Optimise Drives' performing.

Computers are devices which perform mathematical calculations, supported by scientific processes. The earliest known Computer was an Abacus which dates back thousands of years across Asia, Arabia and Europe. In 1617, John Napier from Scotland, invented a manually-operated calculating device which calculated products and quotients of numbers. The method was based on lattice multiplication, an early form of long multiplication.

In the 19th century, Scientists began to invent devices which would be more precise and consistent in calculating numbers, without human error. Charles Babbage, known as the 'Father of the Computer', created the Difference Machine with funding by the British government. Immediately after the release of the Difference Machine, Babbage focused on the Analytical Machine. The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-Complete. In other words, the logical structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era. The Analytical Engine is one of the most successful achievements of Charles Babbage.

In 1976, Apple Inc. (a company founded by Steve Jobs, Steven Wozniak and Ronald Wayne) created the first general purpose, personal computer, called the Apple (1) computer. The desktop computer was made out of wood.

One year later, Apple released their next computer. The iconic Apple II computer which had a memory ranging from 4KB to 64KB, depending on the price scale. This computer inspired the design, look and aesthetics of later personal desktop computers produced afterwards.

The large blank area of the Word document is called the 'Main Body of Text'.

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.
