Coding is what makes it possible for us to create computer software, apps and websites.
The First Programmable Computer
Colossus was the world's first electronic digital computer that was programmable. The Colossus computers were developed for British code-breakers during World War II to help in the cryptanalysis of the Lorenz cipher.
How it works
A computer can only understand two distinct types of data: on and off. In fact, a computer is really just a collection of on/off switches or transistors. Anything that a computer can do is nothing more than a unique combination of some transistors turned on and some transistors turned off. Binary code is the representation of these combinations as 1s and 0s, where each digit represents one transistor. Binary code is grouped into bytes, groups of 8 digits representing 8 transistors.
Programming Languages
A programming (or coding) language is a set of syntax rules that define how code should be written and formatted. Different languages are designed to be used for different purposes – some are useful for web development, others useful for writing desktop software, others useful for solving scientific and numeric problems. Low-level languages are closer to the binary code a computer understands, while high-level languages bear a lot less resemblance to binary code. High-level languages are easier to program in, because they’re less detailed and designed to be easy for us to write. There are:
- Python
- Javascript
- BASIC
- C
- C++
- COBAL
- FORTRAN
- Ada
- Pascal
