But you can't just plug in any hard drive, RAM, motherboard and graphics card to each other and expect them to work. An operating system is needed to make sure those pieces of hardware talk to each other and that everything has the necessary applications.

An operating system (like Windows, Apple or Linux) is connective tissue. Different OSs work differently, but there are similarities to what they're capable of and how they do their important work. Learn the basics with this Operating Systems and Applications training.

For anyone who leads a technology team, this CompTIA training can be used to onboard new or aspiring IT professionals, curated into individual or team training plans, or as a CompTIA reference resource.
