IGCSE Unit 8. Memory and Storage [including questions and answers]

This concise resource is ideal for teaching IGCSE Computer Science, covering the essential topics of memory and storage with clear explanations and practical exercises. It includes answers to all questions, making it perfect for both classroom use and self-study.

Key Topics Covered

• Primary Memory:

  • RAM (Random Access Memory): Explains its role as volatile memory, with distinctions between DRAM and SRAM.
  • ROM (Read-Only Memory): Describes its function as non-volatile memory, used for tasks like BIOS storage.

• Secondary Storage:

  • HDDs: Details magnetic storage, data reading/writing via platters and read/write heads.
  • SSDs: Covers flash memory, its fast data access, and durability over HDDs.
  • Optical Storage: Explains how data is stored and read using lasers on CDs, DVDs, and Blu-ray discs.

• Virtual Memory: Discusses how virtual memory extends RAM capacity using hard drives, including paging and swapping processes.

• Cloud Storage: Highlights the advantages (e.g., remote access, scalability) and potential risks (e.g., security) of cloud-based storage.

Assessment Sections

• Multiple Choice & Short Answer Questions: Cover topics like volatile vs non-volatile memory, HDDs vs SSDs, and cloud storage.
