Logarithms and their applications in coding & computer mathematics

KIDS ONLINE CODING, Teaching Kids Computers

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 […]

How to make a Program Counter using Multiplexers?

KIDS ONLINE CODING, Teaching Kids Computers

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

Introducing Ethical Hacking to Kids

KIDS ONLINE CODING

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

Arrays vs. Classes

KIDS ONLINE CODING

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

Compilers, Assemblers, Linkers and Loaders – what are they?

KIDS ONLINE CODING, Teaching Kids Computers

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

Can you store a 13 digit number in an integer (int) variable in your program?

KIDS ONLINE CODING, Teaching Kids Computers

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.

How Transistors become the CPU – explained simply!

KIDS ONLINE CODING, Teaching Kids Computers

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

Complexity Classes (P, NP) of Problems in Computer Science & Coding

KIDS ONLINE CODING

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

KIDS ONLINE CODING

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.

How early is too early to teach coding to kids?

KIDS ONLINE CODING

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
