9 Programming Languages That Will Make a Major Impact in 2021
In this advanced world, technology is evolving at a fast rate. Every day, new technology is introduced and is making human work easier. The most important skill to learn today is programming languages. When it comes to programming languages, you can’t decide which one is the best. It is a set of instructions to implement algorithms. 

It is not surprising to see alternative technologies surpassing each other with the latest advancements. The rank of Programming languages fluctuates according to the demand. Several programming languages have specific purposes and contain different sets of instructions and keywords to create instructions. 

Programming languages can be divided into two categories: High-level and Low-Level. High-level language allows you to create and write programs that are independent of the type of the computer. It resembles human language and can be understood easily. It is less memory-efficient and executes at a faster pace. 

Low-level language, on the other hand, is represented in binary form and is further classified into assembly and machine level language. It is machine-friendly and can be understood by computers. It is not portable and takes time to execute.
