YOUR COURSE MATERIAL

From the idea to the “I get it”.

A public preview of your learning journey. The complete course is in development.

01Understand+

Understand the device. Become the problem-solver.

02Investigate+

Memory is almost full and apps are slow. Which comparison best tests memory pressure?

03Practise+

Find the bottleneck.

04Explain+

Change one relevant variable and compare the same task. Improved responsiveness supports the memory-pressure hypothesis.

A closer look inside.

Digital learning. Something you can actually try.

  1. 01

    Start with the evidence.

    Task Manager shows memory almost full, high disk activity and moderate CPU use. Record the symptoms before changing settings.

  2. 02

    Working space is running out.

    RAM holds the data active applications need. Under memory pressure, the operating system may move data between RAM and disk, making switching between apps feel slower.

  3. 03

    Make a controlled comparison.

    Close an unneeded memory-heavy app and repeat the same task. Compare memory pressure and responsiveness. Check upgrade compatibility before recommending new RAM.

Find the bottleneck.

A laptop becomes slow when many applications are open. Build a useful diagnosis.

RAM 96% · CPU 24% · Disk 91%
