Computer Hardware

Memory and Performance Basics

Separate installed memory, active demand, paging, and processor pressure so performance recommendations follow measured evidence.

UNTIMED COACHING

Practice before the pressure

Use feedback to correct the model, not merely memorize an option position.

GUIDED PRACTICE

Practice the lesson questions

Answer normal lesson questions without a timer. Every answer includes an explanation, and incorrect answers can be tried again before continuing.

CONCEPT MODELS

Use these visual guides to connect the key ideas before answering the questions.

Map the decisions in Memory and Performance BasicsConnect installed ram, application working set, paging pressure, and processor demand without collapsing their evidence.
Map the decisions in Memory and Performance BasicsA support map connects four subject-specific decisions used in memory and performance basics and shows the evidence produced by each decision.
Installed RAMEvidence for installed ram
Application working setEvidence for application working set
Paging pressurePaging evidence is correlated with the slowdown
Processor demandCPU pressure is separated from memory pressure
Use Bottleneck evidence safelyConnect bottleneck evidence to its approved starting method, expected result, and safety boundary.
Use Bottleneck evidence safelyA practical support model connects bottleneck evidence with a method, result, and explicit safety boundary.
Bottleneck evidenceFocus on bottleneck evidence
Starting checkStart with the bottleneck evidence method
Expected resultThe suspected constraint matches observed timing
Safety boundaryDo not recommend parts from a single percentage
