When we write a program in any language, we declare a lot of variables, arrays, objects in various sections of the program such as the main function, global section, classes, functions, methods, etc. These variables need some space in the Random Access Memory (RAM). So, where are they stored? These variables are stored in two […]
Logarithms is a mathematical concept that is used a lot in computer-science. In this post, let’s understand this concept and its applications in computer-science and beyond. We’ll talk about how logarithms help us in: To introduce, if you know exponentials, then you know logarithms too. Because logarithms are nothing but the inverse of exponentials. For

A program counter is an important component inside a processor. And to build a program counter, we will need a multiplexer, register and a ripple-carry adder. Let’s understand them one by one. A multiplexer is a circuit of logic gates. This circuit is what helps the CPU/processor to fetch a bit of data from memory

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 »
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.
