🔍 Key Topics You’ll Master:

This pack focuses exclusively on the Memory content of the OCR GCSE Computer Science J277/01 specification. You will develop a deep understanding of:

🧠 Random Access Memory (RAM):

• Definition and Purpose:
  Learn what RAM is and why it is called ‘volatile memory’ — understanding how it temporarily stores data and instructions that the CPU needs quickly during processing.

• Types of RAM:
  Explore the differences between Dynamic RAM (DRAM) and Static RAM (SRAM), including their typical uses and performance characteristics.

• Role in System Performance:
  Understand how the amount of RAM and its speed affects the overall performance of a computer, including multitasking and running complex programs.

• Volatility:
  Study why RAM loses its contents when the computer is turned off and why this matters for data storage.

• Memory Modules:
  Learn about RAM modules such as DDR, DDR2, DDR3, and DDR4, and how advancements impact computing power.

💾 Secondary Storage:

• Definition and Purpose:
  Understand secondary storage as non-volatile memory used to store data permanently, even when the device is powered off.

• Types of Secondary Storage:
  Explore different storage devices and media, including:

  • Hard Disk Drives (HDD): Traditional magnetic storage with large capacity and slower access speeds.

  • Solid State Drives (SSD): Faster, flash-based storage with no moving parts.

  • Optical Discs: CDs, DVDs, and Blu-ray discs used for media and backup.

  • Flash Memory: USB sticks, memory cards, and other portable devices.

• Comparing Storage Types:
  Learn to compare devices based on speed, capacity, durability, cost, and typical usage scenarios.

• Uses of Secondary Storage:
  Discover why secondary storage is vital for saving files, installing software, backing up data, and more.

• Storage Capacity and Units:
  Understand how storage is measured (bytes, kilobytes, megabytes, gigabytes, terabytes), and the significance of each unit.
