Course Aim

The course will give learners a real, in‐depth understanding of how computer technology works. The course will give you an insight into what goes on ‘behind the scenes’, including computer programming, which many learners find absorbing.

What will I study?

• Systems architecture, security and software

• Memory and storage

• Network topologies, protocols and layers

• Ethical, legal, cultural and environmental concerns

• Algorithms and programming techniques

• Computational logic

• Data representation

• Translators and facilities of programming languages

What would I enjoy about Computer Science?

A large amount of the course will be spent learning computer programming. Through this study of computer programming, the course will help you develop critical thinking, analysis and problem solving skills. For many, it will be a fun and interesting way to develop these skills, which can be transferred to other subjects, especially mathematics and other sciences, and even applied in day-to-day life.

What careers is it useful for?

The course provides excellent preparation for higher study and employment in the field of Computer Science. The increasing importance of information technologies means there will be a growing demand for professionals who are qualified in this area. Learners who have taken a GCSE in Computer Science and who then progress to study the subject at A Level or university will have an advantage over their peers who are picking up the subject at these levels.
