Overview of Topics Covered
What are programming languages?
Programming languages are used to instruct computers to execute tasks. While there are many types of programming languages, the two main categories are “low level” and “high level” languages. Low level languages use specific instructions that are designed to run on a computer’s processor.
High level languages use instructions that are designed to be easily understood by humans. Programming languages have been instrumental in shaping the world as we know it. From automation in assembly lines, to the creation of the internet, programming languages have played a significant role in the development of our world.
