Hello friends, Hope you are doing good and having fun. I am here with another article on the blockchain. Previously, we have discussed the blockchain, some of its concepts, and its characteristics, and today I will talk about transactions. We would also explore the concept of gas in this tutorial. So let’s start by defining a transaction.
What is Ethereum Transaction?
A transaction is a message signed by an account owner that is added to a block and recorded in the blockchain.
A transaction is initiated by an externally owned account and then it gets transmitted to the Ethereum network.
It can be originated only by an externally owned account (an account owned by a human) and not by a contract account.
Through transactions, one can inter ...
Hello people, I hope you all are having a great time. Let us start our discussion with a simple question, how you keep a track of your progress be it daily, monthly, or yearly? Or how your professor for fluid dynamics or any other course keep you on your toes throughout the semester? Definitely by keeping a proper schedule and record or maybe by tracking your progress through an app or anything manual!
Have you ever thought about how big companies keep themselves on track? How they manage a huge network of employees by keeping in check their progress individually? Or how the day-to-day or hourly tasks are assigned and kept under check daily for every employee of the company? All these things are done through workforce management. Today, we will be ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to Ethereum accounts. I have given you an introduction to blockchain in my previous tutorials, so let’s get started on the essentials of this technology. I am going to start with accounts.
Ethereum Accounts
An account is an important component of the Ethereum system.
It is the main building block and has a balance in ether (ETH) (Ethereum currency).
An account is capable of sending transactions on the Ethereum network.
The interactions between different accounts create transactions that are stored in the distributed database.
Each transaction involves the sender account, receiver account and contract account.
An account can be controlled b ...
Hello friends, I hope you all are doing well. Today we are going to have an in-depth discussion on the Characteristics of Embedded Systems. We have discussed What is Embedded Systems? & Types of Embedded Systems in detail, in our previous tutorial. So, I am hoping that you have a clear idea of Embedded Systems.
Today, we will discuss different characteristics which are found in almost every Embedded system. So, let's get started:
Definition of Embedded Systems
We already know that an embedded system can be defined as,
"A dedicated system specially designed to perform a designated function, with a microcontroller or a microprocessor as its chief component, along with a software embedded in computer hardware, is called an embedded system."

Hello friends, I hope you all are happy, healthy, and, content. Today, our discussion is all about "Diodes". Whoever has been a science student, knows about diodes. Although it seems to be a tiny component of a circuit, apparently it is true but it has a lot of complexities or you can say, it's a storm in a teacup. You might have read a lot about diodes in physics, in today's discussion we would be moving step by step into the pool of diodes from definition to working of diodes, their types, and then lastly its applications. Let's get started!
Diode Definition
First things first, Let's define diode,
A diode is a basic discreet electronic component made up of semiconductor material, used in electronic circuits, which allows unidirectional c ...
Hello Friends, Hope you are doing fine and having fun in your lives. In my previous tutorials on blockchain and Ethereum, I have talked about mining a few times. So, in today’s article, I am going to discuss the concept of mining with you. This is an important part of learning the working of blockchain to see how the decentralization of blockchain happens. Let’s start today’s article by defining mining.
Blockchain Mining
As blockchain is a peer-to-peer network. Mining is also a peer-to-peer process.
Blockchain (or Ethereum) mining is used to verify transactions on the network.
In this process, miners (the person or node who performs mining) add transaction records to the decentralized distributed ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to the Ethereum wallets. I have given you an introduction to blockchain, its characteristics, and an introduction to accounts in my previous tutorials, so let’s get started with today’s tutorial on Ethereum wallets.
What is Ethereum Wallet???
In this section, I will introduce you to the Ethereum wallet and then we will move into its further details.
A blockchain wallet is just like a real-life wallet but in software form. It is the digital form of a wallet.
A wallet is application software that acts as a user interface to the Ethereum network.
The wallet is a system to manage and store the keys.
This digital wallet allows transferring crypto ...
3D Printer is an electronic machine that uses digital data to generate physical 3D models through successive layer printing. A 3D printer can make an object's physical model either scanned by a 3D scanner or designed using a CAD program. 3D Printing is an additive manufacturing technique where successive material layers create a three-dimensional object (Rapid Prototyping). The 3D printing concept is fascinating. Who is not excited about 3D printing? The use of inkjet technology in creating 3D models is a revolutionary method that costs less and saves time by eliminating the designing need for separate model parts. One can use a 3D printer to make a complete model in just a single process.
Several industries use 3D Printers in printing various out ...
Hello friends, I hope you all are happy, healthy and content! Today, we will be discussing the types of embedded systems. But, Before jumping to the types of embedded systems, let's first revise what is an Embedded System? I hope you have a clear idea about the embedded systems, if not, there is always a solution!
Definition of an embedded system
"An embedded system is a unique combination of computer hardware and a software designed for performing a specific function or set of functions from a certain input"
For a detailed overview of the embedded system and its components, you can refer to the complete article on our website about embedded systems.
Types of Embedded Systems
Presuming that you are well aware of the embedded systems and its compon ...
