Check what you remember about storage, memory, the processor, and the operating system.
1. When a program starts, where is it copied from first?
The slides show the program being copied from storage into main memory when it starts.
2. Which part of the computer fetches and executes instructions?
The processor fetches instructions from memory and executes them one by one.
3. At one exact moment, how many instructions is the processor carrying out?
The lesson says the processor executes one instruction that belongs to one program at any given time.
4. Why can it look like several programs are running at once?
The processor switches between programs quickly, creating the impression that they are all running together.
5. What decides how processor time is shared out?
The operating system manages processor time, memory use, and how data is organised in storage.
6. In the lesson analogy, what is the operating system like?
The operating system is compared to a conductor because it coordinates the whole computing system.
7. Which reading would usually rise most during video streaming?
Streaming video needs a lot of data to be retrieved, so network activity is an important measurement to watch.
8. When the computer is idle, what is mostly using the processor and memory?
The monitoring slide explains that when the system is idle, the operating system is still using a small amount of processor time and most of the memory.
