Graph papers are an ever present thing when you’re learning mathematics as a young student. Also called as Grid Paper or Squared Paper, a Graph Paper is a writing paper printed with fine lines, vertical and horizontal, making up a grid of numerous squares. Graph papers are available as books or even as loose sheets […]
I am a software developer using C++, Java, and other programming languages. As a programmer, I had a high regard for programming languages and open source software. During my years of study, I was awed by Dennis Ritchie, Linus Torvalds, Brian Kernigham, and others. It was cool to hold the penguin and go around and

To make games, apps or websites, we need to understand a very interesting concept called “Events”. In this post, we will specifically learn about how to use “Events” in Scratch. To understand events, let’s take an example.If you want to send a message to your friend, what will you do? What are Events in Scratch?

An SSL certificate is a file installed on the server of the website. It is simply a data file containing the public key that is used to encrypt the data being sent to that machine. SSL certificates are issued by certificate authorities, and therefore, browsers consider them trustworthy. We learnt about the TCP 3 Way

As we’ve seen earlier, TCP/IP is the protocol used widely for any communication between a host and a server on the internet. Before starting to exchange data, the client and server engage in a TCP 3-way handshake. The handshake is to primarily establish a connection. TCP/IP can only work between a client and a server

Previously, we have seen the different types of ciphers used in communications. These ciphers are used heavily in encryption and hashing. For example, the AES and DES ciphers use many rotations and transpositions. Similarly, we will see the SHA256 hash algorithm in detail using many ciphers that we learnt before. The Secure Hashing Algorithm (SHA)

Understanding if a school is the right fit for your children has its own process and method to it. It is around this decision that parents typically get into a conundrum on how many schools should I look for, what is a good school for my child, and how I shouldn’t be overdoing this process;

Block coding programs help children learn the logic and reasoning of programming without getting burdened by the syntax of a programming language. Children can focus on the important aspects such as the flow of logic and the basic tenets of programming such as variables, loops, events, and conditional statements. Below is a simple block coding

Ping and traceroute are both network diagnostic tools to understand connectivity between two systems (or IP addresses) on the network. But, they are different from each other in their network objectives. The ping command, as the name says, will test connectivity between two hosts but gives no information on the path between those two hosts.
