Walt’s Answer

If you think about it, computers are all around us and helping us in every facet of our lives. We depend on them in everything we own and do, including our cars, our houses, our jobs, and our social lives. Yet most of us know very little about them or how they work inside. Did you know that the computer knows only how to use two numbers, 0 and 1? Yet with these two numbers alone the computer can make text, colors, and 3-D shapes. It can play video. It can solve complex equations in very little time. It can beat us at chess easily. All with 0's and 1's. So how does it do it?

Computer Science is the study of the mysterious computer and it's inner workings. A computer scientist learns the details of how computers were born, how they work, and all of the amazing things they can do. They learn how to design computers for specific tasks such as controlling an aircraft in flight or having a video conversation with someone thousands of miles away. They learn how to write the software that give the computer its awesome power and how to keep it running, and safe from hackers. In short, a computer scientist learns to control the most powerful of all of human invention and makes it look simple to others.

I highly recommend the field of computer science. There is nothing else like it.

Walt recommends the following next steps:

Learn a simple computer language like "MIT Scratch" and have fun with it
Build a simple computer kit like "ELEGOO UNO"
Take a course or read a book on the history of computers

Moe’s Answer

From a definition perspective, Computer Science is the study of computation and computing devices. One could say, the goal of Computer Science to enable human potential through the use of technology and devices to help us solve problems and complete tasks in a timely and cost efficient manner.


When you study Computer Science, at the core you study computation, algorithms, how computing devices are organized, how information is stored and processed.


Aside from this, you may learn how devices communicate with each other (graph theory, networking, communication), how humans communicate with devices (operating systems, programming, HCI), and how to rapidly develop solutions leveraging existing body of work aka code (software engineering).


You may also learn about securing data (cryptology, encryption), processing of massive quantities of information (databases, big data), enabling indexing and searching across large quantities of data (search engines),


There are many disciplines and sub-domains within the Computer Science discipline. Above are some examples; lots to learn and master and many areas to specialize in should you choose to do so.

Piyush’s Answer

Computer science is the study of computer technology. Unlike electrical and computer engineers, computer scientists deal mostly with software and software systems; this includes their theory, design, development, and application.


Principal areas of study within Computer Science include artificial intelligence, computer systems and networks, security, database systems, human computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, bioinformatics and theory of computing.


Although knowing how to program is essential to the study of computer science, it is only one element of the field. Computer scientists design and analyze algorithms to solve programs and study the performance of computer hardware and software. 


The digital age needs computer scientists and computer science students have excellent graduate prospects. Computer scientists are needed in every type of industry and there are lot of job opportunities.
