As the number of IT certifications and available software on the internet is always growing/changing it can often be confusing when you are first starting out. This is a perfectly normal reaction. I would suggest first picking an area of IT you want to focus on, for example software development, computer networking, cyber security etc. Once you have narrowed down the scope, you can look up beginner courses in the selected field which are available on websites like udemy, coursera etc. These platforms have a good offering of free beginner courses. The good part about following a structured curriculum is that you wont have to worry about looking up resources on multiple different websites. You will also receive a certificate of completion at the end of the course which you can add to your resume. I hope this information helps you. I wish you all the best in your career.
