Non-exam assessment

Sample topics include…

Students will have the opportunity to learn programming in Visual Basic. They will learn to use a systematic approach to problem solving and algorithm creation, representing those algorithms using pseudo-code and flowcharts.

Number bases: Students will learn to differentiate between the following number bases: decimal (base 10) / binary (base 2) / hexadecimal (base 16). They will be able to convert from: binary and decimal / binary and hexadecimal / decimal and hexadecimal and be able to add together up to three binary numbers.

Image representation: Students will understand what a pixel is and be able to describe how pixels relate to an image and the way images are displayed.

Data compression: They will also learn how data can be compressed using Huffman coding and be able to interpret Huffman trees.

Logic gates: Construct truth tables for the following logic gates: NOT, AND, OR.

Systems architecture: Explain the role and operation of main memory and the following major components of a central processing unit (CPU): The arithmetic logic unit, control unit, clock and bus.

Where does it lead?

The career path following on from Computer Science is wide and varied.

Careers exist in web development, computer games, art, media, advertising, consultancy as well as the more conventional commerce route. It is a generalist subject and, as such, can be applied in just about every conceivable industry.

Ultimately, Computer Science gives students the skills to succeed in modern everyday life.
