Applied Computer Science Vs Computer Science

In our increasingly digital world, careers in computer science are more in-demand than ever. But within the field, there are important distinctions between computer science and applied computer science that prospective students should understand.

If you’re short on time, here’s a quick answer: Computer science focuses on the theoretical foundations of computing while applied computer science concentrates on the practical applications of technology.

Defining Computer Science

Computer Science is a field of study that deals with the design, development, and use of computers and computational systems. It encompasses a wide range of topics and areas of specialization. Two major branches of Computer Science are Applied Computer Science and Computer Science.

Theoretical Foundations

Theoretical Foundations form the backbone of Computer Science. It involves the study of mathematical concepts and principles that underlie the design and analysis of algorithms and computer systems. Topics such as discrete mathematics, logic, and formal languages are essential in understanding the theoretical aspects of Computer Science.

For example, understanding the theory of computation helps in developing algorithms that solve complex problems efficiently. It also aids in the understanding of computational models and their limitations.

Algorithms and Data Structures

Algorithms and Data Structures are fundamental components of Computer Science. They are the building blocks for solving problems and organizing data efficiently. Algorithm design involves creating step-by-step procedures to solve specific tasks, while data structures provide a way to store and organize data for efficient retrieval and manipulation.

For instance, algorithms and data structures play a crucial role in search and sorting algorithms, graph algorithms, and database management systems. They are essential for optimizing performance and ensuring the scalability of computer systems.

Programming Languages

Programming Languages are tools used to write instructions that computers can understand and execute. They provide a way to communicate with computers and develop software applications. Different programming languages have different syntax and semantics, each suited for specific purposes.

For example, languages like Python, Java, and C++ are commonly used in a wide range of applications. Understanding programming languages and their features is crucial for writing efficient and maintainable code.

Defining Applied Computer Science

Applied Computer Science is a specialized field that focuses on the practical application of computer science principles and techniques in various industries. Unlike traditional Computer Science, which mainly emphasizes theoretical concepts and algorithms, Applied Computer Science takes a more hands-on approach to solving real-world problems using technology.

Software Engineering

One of the key areas within Applied Computer Science is software engineering. This field involves designing, developing, and maintaining software systems that meet specific requirements. Software engineers use programming languages, tools, and methodologies to create efficient and reliable software applications.

They apply principles of software engineering to ensure that the software is scalable, secure, and user-friendly.

For example, a software engineer might be responsible for developing a mobile application that helps users track their fitness goals. They would need to understand the user requirements, design an intuitive interface, implement the necessary functionalities, and ensure the app performs well on different devices and platforms.

Database Management

Another important aspect of Applied Computer Science is database management. Databases are used to store, organize, and retrieve large amounts of data efficiently. Database administrators and managers are responsible for designing, implementing, and maintaining databases to ensure data integrity and accessibility.

Imagine a large e-commerce website that needs to handle thousands of transactions daily. Database management professionals would be responsible for designing the database schema, optimizing queries for fast retrieval, implementing backup and recovery strategies, and ensuring data security.

They play a crucial role in ensuring the smooth operation of the website’s backend systems.

Computer Networks

Computer networks are an integral part of modern technology infrastructure, connecting devices and facilitating communication and data transfer. Applied Computer Science professionals specializing in computer networks focus on designing, implementing, and managing network systems.

For example, a network engineer might be responsible for setting up a secure and reliable network for a company’s headquarters and branch offices. They would need to understand the network requirements, select the appropriate hardware and software components, configure routers and switches, and ensure network performance and security.

Computer Science Degrees and Careers

Computer science is a rapidly growing field with a wide range of opportunities for those interested in technology and innovation. With the increasing reliance on computers and technology in various industries, computer science professionals are in high demand.

There are different paths one can take when pursuing a degree in computer science, including applied computer science and computer science. Let’s take a closer look at these two options and the potential careers they can lead to.

Research Scientist

A research scientist is someone who conducts experiments, analyzes data, and develops new technologies or theories in a specific field. In the field of computer science, research scientists play a crucial role in advancing technology and solving complex problems.

They work closely with other researchers and industry professionals to push the boundaries of what is possible in computer science. A degree in computer science, whether it’s applied computer science or computer science, can provide a strong foundation for a career as a research scientist.

Research scientists often work in universities, research institutions, or private companies. They contribute to cutting-edge technologies like artificial intelligence, machine learning, and data analysis.


For those who have a passion for teaching and sharing knowledge, a career as a professor in computer science can be fulfilling. Professors not only teach courses but also conduct research and contribute to the academic community.

They play a vital role in shaping the next generation of computer scientists. With a computer science degree, individuals can pursue a career as a professor in universities or colleges. They can teach a wide range of topics, including programming languages, algorithms, computer architecture, and software development.

Additionally, professors have the opportunity to mentor students and guide them in their research projects.

Software Architect

A software architect is responsible for designing and overseeing the development of complex software systems. They work closely with software engineers and developers to create efficient and scalable solutions for businesses and organizations.

A degree in computer science, whether it’s applied computer science or computer science, can provide the necessary technical knowledge and skills to excel in this role. Software architects need to have a deep understanding of software design principles, programming languages, and system architecture.

They often work in software development companies or technology-driven organizations.

It’s important to note that while both applied computer science and computer science degrees can lead to these careers, there may be slight differences in the coursework and focus areas. Applied computer science may have a more practical and hands-on approach, while computer science may have a broader scope with a focus on theoretical concepts.

Ultimately, the choice between the two depends on individual interests and career goals.
