💡 Activity Solution

1️⃣ Draw a block diagram with Input, Output, Primary Memory, Secondary Storage, CPU (ALU, CU, Cache/Registers) and label each.

2️⃣ Given: “Load image from SSD → process filter → display on monitor.” Map each step to units and indicate where the data resides at each step.

• SSD (secondary) → RAM (primary) → CPU/Cache/Registers for filter → GPU/CPU renders → Monitor outputs.

3️⃣ Your PC has 8 GB RAM—explain why a 64-bit OS is recommended and what happens if a 32-bit OS is installed.

• 64-bit OS: can address >4 GB; 32-bit OS limited to ~4 GB, so it can’t fully utilize 8 GB. A 64-bit CPU + 64-bit OS uses the memory effectively.
