In our previous post, we’ve seen how to add two binary bits using XOR and AND gate. Now, let’s say we want to add not two bits but three bits. How would you go about it? Two numbers are A and B and the third number is a carry bit coming from somewhere else (let’s […]

Ethical hackers (white-hat) help organisations in assessing the security situation of the organisation. It is how your parents check the front door by pushing it once just before leaving the door locked to ensure the lock is intact. UnicMinds teaches ethical hacking to young kids with the necessary coding basics and understanding. It is a

Why do we need Classes, why not just use Arrays and work things out? A lot of kids ask this question: why do we need classes, why not just use arrays and put all data together in one array or in a couple of arrays and access? It is understandable why kids are asking this
Arrays vs. Classes Read More »
In this post, we’ll see how learning binary addition serves as the building block for computers. We will build a two bit adder circuit using logic gates. Let’s say we want to add two numbers 6 + 4, we know the answer and it is 10. But, let’s say we want to add two binary

User writes a program in C or C++ language (high-level language). The C compiler compiles the program and translates it to an assembly program (low-level language). An assembler then translates the assembly program into machine code (object). A linker tool is used to link all the parts of the program together for execution (executable machine

This is a post that describes about the basics of integers and it goes on to explain what are the maximum and minimum value an integer can take and why we cannot use integers to store a 13 digit number.
Can you store a 13 digit number in an integer (int) variable in your program? Read More »
Transistors operate as switches just like the ones you see below), the only thing is you don’t switch them on/off physically. Transistors can store binary value 0 (when current is not flowing through the base) and 1 (when current is flowing through the base). But, you may think how is this so different from a

Let’s talk about how functions in mathematics is related to coding in this blog. You must have already written some code in some language and you might’ve used for-loops or while-loops and processed some data using these loops. We typically write different code in various languages to solve some problems like, say sorting an array

This is a post on how atoms, electrons, breadboards, transistors, circuits and PCBs are related to computer science and why we should study them in detail.
This is a post written originally on Today.com (Parenting team) and the link to the article is here. Kids learning to code in school is a craze that has hit public schools in the last several years. It’s all the rage from high schools to elementary schools to after-school clubs at all levels. The movement
