Okay so you've done Paper 1 and survived, what fresh insanity will Computer Science Paper 2 bring?

Never fear, Mrs James is here with some top tips to get you in tip top condition to tackle Thursday's programming and algorithms paper.

You'll smash this!

Panicking about the up coming GCSE Computer Science exam this Friday?

Not to fear! In this mini episode I cover the topics in this paper with some tips about what not to do!

You're doing great - you got this!

In this slightly longer bite size podcast I discuss secondary storage:

• What is it?
• What are the 3 types you need to know about for GCSE?
• What are the 6 characteristics of storage types that you need to be aware of for answering analytical questions in the exam.

Mrs James is back discussing what you need to know about virtual memory and flash storage for your Computer Science GCSE (J276) Specifcally It covers:

• the need for virtual memory 
• flash memory

And I'll try to answer it in the next podcast

Welcome back!

This bite size revision podcast covers the purpose of RAM and ROM memory types and the two main differences between them.

As always if you have any questions feel free to message me here:

I'll be discussing the 3 factors that affect the performance of the CPU, specifically :

1. The clock speed
2. The Cache size
3. The number of cores

If you have any questions feel free to message me here:

Today we're looking at the purpose of the CPU, specifically the following parts from the OCR Computer Science Specification (https://www.ocr.org.uk/images/225975-specification-accredited-gcse-computer-science-j276.pdf)

the purpose of the CPU 

Von Neumann architecture:

• MAR (Memory Address Register)
• MDR (Memory Data Register) 
• Program Counter 
• Accumulator 

common CPU components and their function:

• ALU (Arithmetic Logic Unit)
• CU (Control Unit)
• Cache

the function of the CPU as fetch and execute instructions stored in memory 

clock speed

This short episode is a welcome session to discuss what I will be covering (and what I won't) and a task for you to get hold of a copy of the topic list (from the OCR website) so you know what order the topics I will be covering over the coming weeks.

Link is here for your information: https://www.ocr.org.uk/images/225975-specification-accredited-gcse-computer-science-j276.pdf

Print it out and get highlighting and I'll be back next week with the first topic episode.

Send me a voice message to ask any specific questions and I may include your questions in future episodes
