What Is Programming? A Beginner’s Guide to Getting Started with Computer Science
Programming is the process of writing instructions for a computer to follow in order to process data and solve problems.
These instructions are written using algorithms and implemented through programming languages.
Every programmer works with a specific programming language, and each language has its own features that make it suitable for different tasks and industries.
A Brief History of Programming Languages
In the early days of computing, programming languages were extremely complex and relied heavily on numbers.
This made programming difficult and limited to specialists.
With the invention of transistors and the evolution of computer hardware, programming languages became more human-readable and easier to use. 🛠️
This shift opened the door for more people to enter the world of software development.
How Do You Write Code?
Writing code follows a logical process:
- Understanding the problem
- Breaking it down into smaller steps
- Writing connected instructions that lead to a solution
This process naturally improves your critical thinking and analytical problem-solving skills, which are essential for any programmer.
Where Should Beginners Start?
One of the best starting points for beginners is CS50, a famous computer science course offered by Harvard University. 🏛️
It takes learners from zero knowledge to advanced concepts in a structured and practical way.
