Troubleshooting Methodology
This is the first step in the CompTIA troubleshooting methodology
What is "Identify the problem"?
This display type uses self-emitting pixels and delivers deep blacks
What is OLED (Organic Light-Emitting Diode)?
This version introduced in 1996 had very slow transfer speeds.
What is USB 1.0?
This port transmits both audio and video and is commonly used in TVs.
What is HDMI?
This type of storage is faster than traditional HDDs and has no moving parts.
SSDs use flash memory, improving speed and durability.
In this step, you brainstorm what might be causing the issue.
What is "Establish a theory of probable cause"?
This LED technology offers higher brightness and better local dimming.
What is Mini-LED?
This 2000 version of USB introduced high-speed transfer at 480 Mbps.
What is USB 2.0?
This network port is used for wired internet connections.
What is RJ-45?
This RAID level mirrors data across two drives.
What is RAID 1?
You confirm if your hypothesis was correct in this step.
What is "Test the theory to determine the cause"?
This LCD panel type offers wide viewing angles and good color accuracy
What is IPS (In-Plane Switching)?
This version introduced SuperSpeed and 5 Gbps transfer in 2008.
What is USB 3.0?
This SATA-based connector is used for connecting external drives.
What is eSATA?
This power supply type lets you detach unused cables.
What is modular power supply?
You determine how to solve the issue and carry it out in this step.
You determine how to solve the issue and carry it out in this step. A: What is "Establish a plan of action to resolve the problem and implement the solution"?
This LCD panel type is known for fast response times but poorer color.
What is TN (Twisted Nematic)?
Introduced in 2013, this version added SuperSpeed+ at 10 Gbps.
What is USB 3.1?
This older power connector is commonly used for internal components.
What is Molex?
This component spreads heat away from the CPU.
What is a heat sink?
This final step ensures the problem is resolved and helps prevent it from happening again.
What is "Document findings, lessons learned, actions, and outcomes"?
This panel type balances color, contrast, and response time, making it versatile.
What is VA (Vertical Alignment)?
This version unified with Thunderbolt 3 and reached speeds up to 40 Gbps.
What is USB4?
This port allows the installation of capture and expansion cards.
What is PCIe slot?
This RAID level uses striping and one for parity across three or more drives.
What is RAID 5?
