Diagnostic tools are used:

  • to specify the performanceperformanceperformance of the system componentscomponentscomponents,

  • to monitor the operation of the computer components,

  • to detect the instability of the computer at long‑term operation and high load,

  • to detect the cause of a defect.

Operating systems offer built‑in functions that can help diagnose the status of the computer. The selected tools of Windows that facilitate the diagnosticsdiagnosticsdiagnostics of the system are discussed below. Task Manager displays the list of running processesprocessesprocesses and servicesservicesservices and informs about the used resources of the particular componentscomponentscomponents of the computer. It also enables to start and stop applications and services.

Ilustracja interaktywna przedstawia formatkę Task Manager z aktywną kartą Performance. Po lewej stronie miniatury czterech wykresów. Każda z miniatur prowadzi do monitorowania innych funkcji komputera. Pierwsza – niebieski wykres, obok napis 5% 3.29 GHz. Druga – fioletowy wykres, obok napis 1.3/2.3 GB (57%). Trzecia - fioletowy wykres, obok napis 1%. Czwarta - pomarańczowy wykres, obok napis S:0 R: 0 Kbps. Na ilustracji widoczne są numery, a na nich podpisy. 1. CPU – the current use of the processor (in percentage). {audio}, 2. Memory - the current use of the physical memory (in megabytes). {audio}, 3. Disc - the current use of the disc (in percentage). {audio}, 4. Ethernet – the transfer speed (in kilobits per second). {audio}

The tools for discdiscdisc checking scan a disc in search of errors. They enable to repair them automatically, if it is possible. They can also identify bad sectors, i.e. defective sectors on the disc. CHKDSK is run after restarting the computer and before the startup of the graphical environment. Disc errors usually occur after the crash of the computer.

Interaktywna gra, polegająca na łączeniu wyrazów w pary w ciągu jednej minuty. Czas zaczyna upływać wraz z rozpoczęciem gry. Jeden ruch to odkrywanie najpierw jednej potem drugiej karty z wyrazem. Każdy wyraz jest odczytywany. Kolejny ruch to odkrywanie trzeciej i czwartej karty. W ten sposób odsłuchasz wszystkie wyrazy. Nawigacja z poziomu klawiatury za pomocą strzałek, odsłuchiwanie wyrazów enterem lub spacją. Znajdź wszystkie pary wyrazów.
