Join Mike Meyers for an in-depth discussion in this video Primary PC components, part of CompTIA A+ Exam Prep (220-901) Part 1: Core Processing.
- The CompTIA A exams use a lot of what I would call…unique terminology when it comes to…the main components of your PC.…So what we're gonna do right now…is nice and slow take a look at…a typical desktop system and define…what the names of all the different components are…and also how they fit into processing,…be them processing, input or output.…So let's just go on down the list here.…This right here, according to CompTIA…is the system unit.…The system unit is where pretty much…all of your storage and all of your processing is done.…
Inside the system unit is your motherboard,…your CPU, your RAM, hard drives,…optical network connections, pretty much…all that is your computer is done here.…Now, a system unit by itself,…as long as it's got electricity…and it's booting up, is a perfectly good computer.…The problem is, is it has to work with these…terrible, terrible things called human beings…and that's why everything else other than the system unit…is a peripheral.…So, starting off, here's a good old monitor here.…
The CompTIA A+ 220-901 exam is comprised of six key parts. The first, core processing, is covered by this course.
