Overall, the primary focus of this course is logic building within the context of computer science and programming.

Throughout each chapter, you will get hands-on experience with exercises and quizzes to solidify what you’ve learned. If you’re looking to build strong programming fundamentals then this course is the perfect place to start.

Introduction to Computers & Programming

# What is a program?

When a manager wants an employee to perform a task, they give out specific instructions to carry out the job. For example, if your manager needs you to find the profit for June, they will direct you to subtract expenses incurred from the revenue earned in June. Similarly, when we want a computer to calculate the profit or solve a problem for us, we must provide clear and concise instructions on how to solve the problem.

The set of instructions to be executed by a computer to solve a particular problem is called a **program**. To give such instructions, humans communicate with computers using formally created languages, called **programming languages**, that computers can understand. Let’s see some of the categories of programming languages.

# Categories of programming languages

Programming languages can be broadly categorized into:

* Low-level languages

* High-level languages

Understand what a program is and how computer languages enable us to write a program.
