Connectors and Adapters

Every personal computer cable connector is designed to provide a specific function, and some of these capabilities have changed dramatically through the years. In this video, you’ll learn about standard computer connectors and how to use cable adapters to change gender, connect serial connections, or extend network connections.

Computer Cable Types

There are many different personal computer cable types, conventions, and standardizations. In this video, you’ll learn about the different types of cables, how cable design ensures the correct functionality, and an overview of the most common cable types that a CompTIA A+ certified professional might see every day.

Common Computer Ports

The connections into a PC are as varied as the components themselves. Fortunately, there are a number of standardized ports that are common across all computer makes, models, and manufacturers. In this video, we’ll look at the most common connector types and show you what type of components use these ports.

Installing and Troubleshooting Computer Power

Troubleshooting power problems with personal computers goes well beyond the power cord. In this module, we’ll show you how to use a circuit tester and multimeter to troubleshoot power on the motherboard , the PC components, and the power outlets themselves. You’ll also learn about power protection systems and the process for installing a PC power supply.

Computer Power Overview

Every computer system has a power supply, so the CompTIA A+ professional needs to have a solid understanding of personal computer power supply characteristics and types. In this video, you’ll learn about the basics of electricity (i.e., amp, volt, watt), the type of connectors you can expect to see on a power supply, and the industry standards that are used to perfectly match your motherboard with your power supply.

Professor Messer’s Free Certification Training Courses: Frequently Asked Questions
