1.2 Software and Software Development
Click here for recommended OCR A-Level Computer Science textbooks.
This video explains different types of data structures - 1 dimensional arrays (or just 'arrays'), 2 dimensional arrays, and records. The example code is given in Python, which makes this video perfect for many GCSE courses.
1.2.2 Applications generation
Utility Software and Models
Some students find the difference between operating system software and utility software hard to understand. This video should help clarify the differences (and also the difference between application software and utility software), with plenty of good examples. It also covers the basics of computer software models.
Translators (Assemblers, Compilers & Interpreters)
The relationships between translators, compilers, and interpreters confuses many students. Throw in assemblers and it can be hard to understand anything about this topic. This video tries to address that confusion, with clear explanations and lots of clear examples.
I'd recommend watching the video Machine, Assembly & High-Level Programming Languages (from the same creator) first, particularly if you're unclear about the difference between assembly language and higher level languages like Python.
