s4cs00 introduction to computer science
So you fancy doing Computer Science at GCSE level or even beyond?
Computer science as a subject was born out of the automation of mathematics. There are two branches of mathematics - continuous and discrete. Continuous mathematics deals with continuous data and calculus. Discrete mathematics deals only aspects of mathematics that do not employ the continuous method of calculus but instead, deal with discrete data. As computers are made from switches that can discretely be on or off, they are discrete mathematical machines. However, they can approximate solutions to continuous equations much faster and more accurately than a human can ever do.

During a GCSE Computer Science course, you will learn about ...
Computer systems
Computing hardware
Software
Data representation
Databases
Communications and networking
Algorithms
Programming
So, who do you see yourself as?

As computer scientists, we create the technology that other people use. Would you rather be a mechanic or a driver?

Activity 1
Problem Solving Challenges
The main thing that Computer scientists do is solve problems. The problems might be easy to solve and take very little time or they may be hard to solve and take a lot longer. Some problems that Computer Scientists are faced with have never been solved!

Task 1.1 Problem solving challenges
Download the Starter Problems worksheet and try to complete the problems by typing the answers on the worksheet. For some, you will need a calculator. How many can you do? Ask your teacher for the solutions when you have attempted them. You will be told whether you are right or wrong, but you won't be given the answer!
Did you persevere until you got the correct answer?
If you did, you might enjoy Computer Science!
OUTCOME : You should have a headache afterwards!
