In such a rapidly changing field, what do we then consider before choosing to go down the computer science pathway?
What is Computer Science?
Computer science is the study of computers, computation, information and automation. It is a discipline that focuses on understanding how computers work and the science behind the technologies that we use everyday.
Rather than just programming, computer science incorporates elements such as algorithms, mathematics, logical thinking and problem solving abilities that are used to build software and design systems that make up our digital ecosystem today.
One core pillar of computing is known as ‘first-principles thinking’, where individuals are encouraged to find the true meaning of concepts and theories by examining it thoroughly themselves, rather than relying on established notions.
This type of approach, key in STEM fields, has proven to develop strong cognition by instilling computational skills such as logical reasoning and problem solving that strengthen your position in any career – whether you stay in tech or pivot to media, engineering or science.
Some core areas of study in computer science include:
Algorithms & Data Structures | Series of mathematical and logical rules used to process, store and retrieve data. |
Artificial Intelligence & Machine Learning | Designing AI systems that can effectively read, process and generate data provided by human intelligence, using concepts such as learning, reasoning and decision-making. |
Data Science & Big Data | Extracting knowledge and valuable insights from complex and unstructured data from analyzing large datasets. |
Software Engineering | The design and development of software programs and applications. |
Cybersecurity | Protecting computer systems, networks and data from unauthorized access, attacks or damage |
Computer Architecture | The design and organization of the physical components and machinery that make up computers. |
Computer scientists often design, develop and analyze software and hardware systems to solve complex computational problems. This can be applied to several fields such as in business, education or finance. This makes the role of a computer scientist diverse.
They may be involved in the development and design of software systems, writing the code that these systems run on, creating entirely new programs or optimizing the efficiency of computer systems as well.
However, the role of a computer scientist continues to expand and evolve at present, meaning that the computer scientists aren’t just confined to a single role, they have a skillset that puts them at the forefront of a multitude of opportunities in tech.
What skills do you learn in Computer Science?
There proves to be a steady demand for computer science graduates across tech, finance, healthcare and entertainment, making it a desirable career for many. Moreover, computer science is a highly versatile field that does not offer just a single track.
It opens doors to many other related fields such as in cybersecurity, data science, software engineering and cloud computing to name a few. Across the board, computer science foundations allow learners to effectively break down complex problems and build from the ground up – a critical skill for almost every occupation.
Here’s what you’ll learn if you make the decision to pursue a Computer Science pathway:
Programming and Problem-Solving Skills
Computer science offers a range of key skills which include programming, logical thinking, a strong grasp of computer architecture and data structures to name a few. As such, you will be introduced to:
Programming languages such as Python, Java and C++
Breaking down complex problems into smaller, logical steps
Abstraction as a method used to hide complex mechanisms behind simpler interfaces building on organizational skills and overall attention to detail
Work based on immediate feedback from code, enabling critical thinking to implement successful solutions
Pattern recognition by identifying recurring sequences and data structures and applying standardized, original methods to solve them for maximum efficiency
Programming doesn’t just teach you how to code, it teaches you how to think. Coding is a method for individuals to deconstruct problems and build them back up from scratch in a precise, causal sequence. For instance, coding relies on logical rules such as ‘if’, ‘then’ and ‘else’.
Computer scientists have to use these functions to deliver precise instructions to computers in a way that is mapped out through cause and effect branches. With every rule or instruction given, there is a result.
This means that professionals have to train their minds to map out the cause and effect of each of their instructions (for example: “if” the password is correct, log in; if not, show an error) — prompting them to think logically and analytically to provide the most precise instructions that deliver the most accurate computer outputs.

Mathematical and Analytical Skills
Computer Science places a large emphasis on abstract, structural and discrete mathematics, rather than the mathematical concepts used for fields such as in perhaps engineering.
As such, this type of math prompts students to solve problems logically and builds the foundations of the computer science specialism. Key mathematical skills in computer science include:
Discrete mathematics used to study distinct, countable objects such as integers
Boolean algebra to write logic for if/else statements
Graph theory for mapping apps or analyzing social networks (eg: friend connections on Facebook)
Combinatorics to count possibilities and optimize data processing
Linear algebra including lines, vectors and matrices for graphics and 3D programming and machine learning
Probability and statistics used to build AI systems and algorithms
