A451

A451Cover261x400A451 – the revision guide, covers the A451 Computer Systems and Programming specification in OCR’s GCSE Computing ¬†course. ¬†Each part of the specification is taken in turn and notes, past paper questions and the associated mark scheme answers are used to illustrate each section. We have found from personal experience that having covered the course throughout the year, students find it extremely helpful to conclude their preparation by going through past paper questions carefully in conjunction with a well written set of notes.

 

The OCR specification for this course covers the following topics.

  • Fundamentals of Computer Systems
  • Computing Hardware
  • Software
  • Representation of Data in Computer Systems
  • Databases
  • Computer Communications and Networking
  • Programming
