Study Notes
Diagnostic Tools for Testing Installed Hardware Components
-
Digital multimeter: a device that takes various measurements to test circuit integrity and electricity quality in computer components, displaying information on an LCD or LED screen.
-
Loopback adapter (loopback plug): tests basic functionality of computer ports, specific to the port being tested.
-
Toner probe:
-
A two-part tool consisting of a toner and a probe.
-
The toner generates a tone that travels through a cable, and the probe traces the cable, emitting a tone through a speaker when near the cable.
Software Tools for Diagnosing Computer and Network Problems
-
Various software tools can help technicians pinpoint and troubleshoot problems, many of which come with the Windows operating system.
-
Disk Management Tools:
-
Help diagnose disk errors, prepare disks for data storage, and remove unwanted files.
-
Include FDISK (command-line tool for creating and deleting partitions on hard drives), Disk Management Tool, Format, ScanDisk/CHKDSK, Defrag, Disk Cleanup, and System File Checker (SFC).
Test Procedures
- A set of steps guiding technicians through testing the installation to ensure everything is tested thoroughly.
- Include:
- Gathering test information: running required tests and recording results in a log.
- Validating test information: checking data accuracy by re-running tests.
- Responding to test information: recognizing successful or problematic tests.
- Checking specification: verifying that the installation meets specifications.
