Career Paths Within IT

Your instructor will go over the IT Certification Roadmap from CompTIA, a vendor-neutral nonprofit organization that serves as an independent source of information on a wide range of technology topics. This roadmap shows what classes you need to take based on your desired career path as well as illustrates the different segments within the IT industry. The instructor may also share his or her recommendations for building a strong foundation in IT. All of this will help you figure out how to start a career in IT.

Computer Hardware

What's inside of a computer? How do the physical components of a computer work together? How do you build a computer? Or take one apart? If you're starting out in IT, these are all things you'll need to know. Your instructor will share what the inside of a computer looks like, including all of the different parts and their functions.


Networking in IT is broadly defined as the way computers connect to each other and talk to each other. Your instructor will share the physical devices and virtual components involved in this process as well as a little about the networking process itself.


If you're reading this blog on a phone or computer, you're using an operating system to do it. An operating system, or OS, is a program that manages a device's resources. Examples of operating systems are Microsoft Windows 10 and Apple iOS 15. Virtualization allows you to run multiple operating systems at the same time from the same device. Your instructor will share what virtualization looks like as well as some of the reasons you would use virtualization such as for networking, cloud computing, cybersecurity, and ethical hacking.


Social engineering, sometimes called "hacking the human", is the practice of tricking someone into giving up their passwords or other sensitive information that can then be used to harm them and steal their money. A very common way cybercriminals target individuals and companies is through phishing. Your instructor will share some of the tactics phishers use including emotional manipulation to cause the target to feel either fear or excitement, accompanied by a sense of urgency, leading them to click on a link, download a file, or send the attacker their login info in order to resolve an issue or claim a prize of some kind. Phishing emails are often made to look like they come from large, well-known companies such as Apple or Amazon and are often riddled with grammatical errors. See an example of a phishing email below:
