In this post I will discuss the evolution of HTTP and the difference between HTTP and HTTPS in simple term so that it makes sense quite easily.  What is HTTP It is always necessary to know something about basics before going to the advanced topics. HTTP stands for H yper T ext  T ransfer P rotocol. It is the system for transmitting and receiving information across server and the client.

To avoid the piling up of me...
