A Complete Overview of Computer Science for Beginners

By Taryn Brewer on Aug 21, 2022

Learning how to get into computer science can be a daunting task. There are so many career paths down which a computer education can take you, so many programming languages to master, and so many skills to learn. I’ll give you a basic rundown of what computer science is, along with a plethora of resources and tools to help you carve out your own pathway into a computer science career .

What is computer science? #

Computer science, to put it simply, is the study of the principles and use of computers. The field uses the principles of mathematics, science, and engineering to study and develop computers, hardware, software, networks, databases–even artificial intelligence. It is a highly complex and critical field, as computers and technology have been integrated into virtually (that’s a little computer pun for you there) every industry, organization, and economic center in some way.

Computer science vs. computer engineering #

Computer science deals more with the study of software, while computer engineering deals more with hardware and often even bleeds into electrical engineering. Oftentimes, someone will get their undergrad in electrical engineering and either double or minor in computer science. While there can be a lot of overlap between both fields, being specific on which courses you want to take will help quite a bit.

What are the main basics of computer science? #

Computer science includes:

Sound like a lot? Well, maybe, but learning the basics of computer science is actually simpler than you may think.

How to get started with computer science #

There are lots of routes you can take to get started. Formal education is one option, as there are many different set pathways to travel, complete with prebuilt lists of courses to follow. There are many beginner computer science classes that cover the fundamentals, and as you further yourself in your chosen degree you can pepper in extracurricular courses or spice things up with an interesting minor or an ambitious double-major.

Your main choices come down to:

Computer science for dummies #

Let’s say formal education isn’t your style. Going the self-taught route isn’t always easy, but it allows you to work at your own pace and strengthen your problem-solving skills. We will go on a quick run-down of coding languages you can focus on (and reasons why you should) before moving into resources that can aid you on your computer science journey.

Let’s talk programming languages #

Where to start? With over 700 computer languages out there, it sounds impossible. However, like most things, programming languages follow a power law so there aren’t that many popular ones. Anyways, we can start with some of the simplest languages to learn. There are some general categories we can use to separate programming languages into different groups: procedural, functional, and object-oriented languages.

Cornerstone languages of the web #

Whatever specialty you choose, as long as it includes a visual component, CSS and HTML will likely play a critical role. Almost every site you see, and every web game you play, uses some form of CSS or HTML. Javascript is another one that can be considered a cornerstone language–or a language on which the basics of a solid programming career are built.

Common programming languages #

A sneak peek beyond the basics #

Once you’ve mastered a few basic languages, you can move on to more intermediate languages. Remember, these are harder languages, many of them are meant to complement basic programming languages. So why talk about it now? While it’s good to know what to look forward to in your career, it also gives you an idea of how these languages are interwoven together and build on top of each other in order to create specialized designs and meet specific needs. These are just a few samples of intermediate programming languages that are out there:

A collection of resources for learning CS as a beginner #

Now that we’ve covered a few of the more common programming languages, it’s time to move on to the next phase: actually learning how to use and apply them. For that, resources are needed. If you’re looking to do independent learning, consider reading some computer science books.

Computer science podcasts #

Podcasts are an excellent way to learn on the go. Here are a few you can check out to get yourself more immersed in the wide, wide world of computer science. That said, make sure you aren’t only learning with podcasts, when learning computer science you do need to write and practice writing code yourself.

Computer Science Youtube Channels #

If you’re more of a visual learner, consider checking out different Youtube channels and videos. There are thousands of video tutorials for beginners with different perspectives on computer science. Here’s a list of a few channels and videos to help you get started. Now, watching videos is no substitute for actual coding, but these should give you a basic idea of things you can learn (along with providing you interesting to follow tutorials).

The same thing I said about podcasts applies to YouTube videos however, make sure you’re getting hands-on practice writing code and building projects. Just consuming information won’t be enough.

Computer Science Bootcamps for newbies #

If formal schooling and going completely self taught aren’t the routes for you, bootcamps are an excellent way to achieve computer science knowledge at a rapid pace. They have shorter durations and are often very intense, though they are typically more affordable than getting a 4-year degree. Different camps will cover different materials in their courses. Oftimes, the tradeoff is that a bootcamp may or may not offer a job guarantee . When choosing a bootcamp, make sure you thoroughly inspect each one to decide if it’s the route for you.

Computer science projects for beginners #

Whether you get formal schooling, do a bootcamp or learn independently, I cannot begin to emphasize the importance of working on personal projects. It’s a great way to build skills and prove those skills with something tangible to show for it. For a project, you can focus on what particular skills you are looking to develop. So what are some great computer science projects for newbies? Let’s look at a few:

  1. Build a website landing page
  2. Create a platformer game
  3. Build a multi-page, responsive website
  4. Creating a random number generator
  5. Real-time weather forecasting app
  6. Library Management System
  7. Real-time Web search engine
  8. e-Authentication network
  9. Build a chess game
  10. Build a web scraper
  11. Create a basic calculator
  12. Make a mobile app
  13. Flip images
  14. Make a countdown timer
  15. Build a drawing app
  16. Create a book finder app
  17. Create a Javascript slideshow
  18. Create a to-do list app
  19. Magic 8-Ball
  20. Build a calendar application
  21. Currency converter
  22. Stock ticker
  23. Duplicate text checker
  24. Basic hospital management system
  25. Task management application

Starting a computer science path #

Once you’ve completed your schooling, or even before you’ve finished, start look for jobs straight away. Familiarize yourself with job requirements in order to find an entry level job–though some jobs and projects can launch you into intermediate level jobs. The outlook for computer jobs is bright , and with the proper set of skills learned, (and a brushed up resume ) you should be able to find a job in no time. If you’re unsure of what jobs to look for check out some of our other articles for more insight.

Can you really learn computer science? #

Computer Science is, overall, a blend of math and science, of soft skills and hard skills, all it’s all tied together to keep our apps, phones and computers running. Pursuing computer science requires you to become a rapacious learner with an insatiable curiosity and a strong propensity for problem-solving. Even if you think of yourself as a computer ‘dummy’, if you invest the time and effort, computer science will reward you, whichever path you choose to pursue.

Good luck!!!
