What is Computer Science?

Computer science is a field of study that focuses on the theoretical, practical and social aspects of computing and information processing. It involves the design, development, analysis, and application of computer technologies. As any beginner what is computer science course will tell you the term “computer science” has a more general meaning than computer programming or software engineering, since it can be applied to all fields that use computers in some form, including hardware design and many applications like digital signal processing, data mining and artificial intelligence. 

Computer Science Vs. Computer Science Engineering

Computer Science is the study of computers and their applications. It is a very broad field and can be studied in many different ways. Computer science engineers typically have to know how to write code while computer scientists are more theoretical in their approach. They may not be required to write code but they need to understand how the machine works. So if you want to be a ‘software developer’ then you might want to consider doing a course in computer science engineering; whereas if you want to become a research scientist then you should probably do a course in computer science

Roadmap to learning computer science

Computer science is a broad field and you can find jobs in almost every industry. There are many different ways to learn computer science, so it’s up to you to decide how much time you want to spend on it.


  1. Pursue undergraduate or post graduate degrees

If you want to pursue a formal education, then enrolling in a reputable online platform or university that offers graduate or post graduate programs with placements is the best way.. You can either get an undergraduate degree or a postgraduate degree in computer science. If you have an interest in coding and programming, then this is the best option for you.

  1. Online courses and MOOCs

There are many online courses offered by universities such as Stanford, MIT etc., where anyone across the globe can learn all kinds of concepts related to computer science, from basic coding skills to advanced algorithms and data structures etc., These courses are usually free but sometimes they may charge some fees too depending upon the type of course being offered by them.

  1. Books

Books are a great way to dive into a subject, but they do have some limitations in terms of interactivity. However, if you’re serious about learning how to code, it’s important that you use multiple methods of instruction. So you can use various books as a complement to other means of learning.

Career options for a student of computer science

There are many exciting and rewarding careers in computer science. Below is a list of some of the most popular career options for computer science majors:

  • Artificial intelligence: Computer scientists who specialize in artificial intelligence can work on projects that involve designing algorithms to solve problems within their industry or company.
  • Computer architecture and engineering: Computer engineers design computers from scratch, build software systems and networks that run on them and write applications that make use of these systems. They also test these systems for security flaws and bugs (known as “bugs”)
  • Computer performance analysis: This area focuses on finding ways to improve computer performance through better design or hardware configuration changes

  • Computer security and cryptography: The security industry continues to grow as more companies rely on technology, but also because cybercrime is on the rise. People who study computer security are able to analyze systems for vulnerabilities as well as design new ways to protect them from hackers and other threats.
  • Computer networks: Networks are more centralized than they used to be before cloud computing became popular, but there will always be a need for people who can keep networks running smoothly and efficiently by ensuring that all parts are working together properly—whether that means fixing software issues or physical hardware failures like crashed hard drives or faulty motherboards
