Theoretical vs Practical Computer Science

Theoretical computer science is a mathematical approach to computer science. It’s like the ‘what if ‘part of computer science, where we explore the possibilities and limits of what computers can do. On the other hand, practical computer science focuses on the practical application of computer science for developing better software and computers. It’s like the ‘how to ‘part, where we use theoretical knowledge to build things that can improve our lives. Both theoretical and practical computer science are essential for the advancement of the field. Theoretical computer science helps in developing new computational possibilities, which are crucial for practical computer science.
