My channel primarily looks at the Computer Science across the Key Stages of the British and International Curriculum. I have also included a series of videos which cover each topic from the Syllabus for the 2023-2025 Cambridge IGCSE. There are also examples of how to best answers exam questions from both papers 1 and 2 of the iGCSE.

🤩 Thank you so much for your support... it means a lot! 😍

Cambridge IGCSE™ (9–1 0984) (A*-C 0478)
For exams in 2023, 2024 and 2025.

Cambridge IGCSE Computer Science helps learners develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. They apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. Learners also develop a range of technical skills, and the ability to effectively test and evaluate computing solutions.

Studying Cambridge IGCSE Computer Science helps learners appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to Cambridge International AS & A Level and is valuable for other areas of study and everyday life.

hello, i have a question, if we can use the hdd or sdd to reallocate and run prcesses from the ram when it gets full, then why dont we just use HDDs and SDDs as RAM?

[djvts]

what will we if we don't know what is a spehoro or etc

[slaveofAllah]

A big kiss for you. I wont recomend it to my friends so im the only one that passes
