CompTIA A+ 220-701: 1.8 – Input Devices

There are many ways to get data into your computer, and in this video you’ll learn about the most popular input devices. We’ll discuss mice, keyboards, bar code readers, biometric devices, and much more.

CompTIA A+ 220-701: 1.7 – Display Devices

We can’t easily use our computers without some type of display device, and you’ve got many to choose from. In this module, you’ll learn about CRTs, display projectors, display connector types, and the specifications you should consider when purchasing a new LCD monitor.

CompTIA A+ 220-701: 1.5 – Cooling Systems

A hot computer is an unhappy computer. In this video, you’ll learn show heat sinks, cooling fans, liquid cooling systems, and thermal compound are important to keep our computers running cooler and more efficiently.

CompTIA A+ 220-701: 1.4 – CPU Technologies

CPUs are extremely complex components, and their inner-workings can contain a mix of memory caches, multiple processor cores, and advanced queuing mechanisms. In this video, you’ll learn how these technologies work together to create today’s modern central processing units.

CompTIA A+ 220-701: 1.3 – Computer Power

Without the supply of power, your computer won’t have much to do. In this video, you’ll learn about power supply standards and how different connectors are used to power the components inside of modern personal computers.

CompTIA A+ 220-701: 1.2 – BIOS and CMOS

We rely on the BIOS to test our computer and start our operating systems, but what is really happening under the surface? In this module, you’ll learn about the BIOS works and we’ll demonstrate the basics of starting and configuring BIOS settings.
