Mathematics can be found everywhere and it is deeply ingrained into everything around us. But, it is not easy to know the beauty of this subject. It is very much like learning to code, the process could be sometimes daunting when not taught in the right way, but once you learn the art of coding […]

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

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

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
