# Computer Technology

Let’s learn some computing for **great good!**

You are welcome to PrograCoding computer learning section. We will learn about the different aspect of computing in this section. Especially, this section has been designed for the **beginners** & **self-learners** with simple Implementation of learning.

You can learn here the basic computer problem and daily computing issue, set up an internal construction of the computer and even computer programming and software development. Just start learning and **be a guru**.
