One of the most significant distinctions between "cloud computing" and the "Internet of Things" is that cloud computing offers hosted services through the Internet, while the Internet of Things does not. On the other hand, IoT connects smart devices in the area to the network so they can share and analyse data that helps them make decisions. What is IoT? The phrase "Internet of Things, " sometimes known as "IoT, " refers to the collective network of linked objects as well as the technology that permits communication between devices and the cloud, as well as between the devices themselves. As ... Read More

The Internet of Things, also known as IoT, is likely to be the next major paradigm shift in the field of information technology after the cloud and the most significant technological advancement since the introduction of the Internet. IoT holds the promise of integrating physical objects, such as home electronics, into the existing online space. It paves the way for a vast array of new innovation opportunities, which will further contribute to the development of novel types of interactions between humans and things. We live in a world in which the majority of electronic devices are already connected to the ... Read More

Hashing is a computation technique in which hashing functions take variable-length data as input and issue a shortened fixed-length data as output. The output data is often called a "Hash Code", "Key", or simply "Hash". The data on which hashing works is called a "Data Bucket". Characteristics of Hashing Technique Hashing techniques come with the following characteristics − The first characteristic is, hashing technique is deterministic. Means, whatever number of times you invoke the function on the same test variable, it delivers the same fixed-length result. The second characteristic is its unidirectional action. There is no way you can ... Read More

Information Technology used traditional centralized computing framework for many years, where one server was connected to multiple clients and was responsible to fulfill the requests coming from them. This client-server architecture has its own limitations such as possibility of scaling to some extent only vertically, ability of the server to process only certain number of requests when all clients send requests at a time, and threat to functionality if the server fails. The shortfalls were overcome by Distributed computing and then further with Edge computing frameworks. This article briefly elaborates on each of the computing frameworks and the differences between ... Read More

While traditional marketing still holds its place by billboards, distributing handouts, promoting on television and newspaper, etc., the digital marketing has opened-up new gates to market the products and services quicker, reaching out to vast customer base, and providing measurable insights of the marketing campaign. What is Digital Marketing? It is tactics used in promotion of brands by reaching out to customers via Internet and using various digital communication channels such as email, social media, web-based advertising, text messages, and multimedia messages. Examples of Digital Marketing Here are some forms of Digital Marketing − Search Engine Optimization (SEO) − ... Read More

Computer systems have been handling data since decades, but the volume and speed of handling has become phenomenal in the last few years. Data processing means "the collection and manipulation of items of data to produce meaningful information", has been evolving in terms of speed, efficiency, and leveraging the computing resources, till date. In this article, we will see two important techniques of data processing in the field of computation − Batch processing and Stream processing. We will elaborate them in detail and see how they are different. What is Batch Processing? Batch processing is technique of processing large amount ... Read More

Data transmission has been crucial in the age of digital communication. Either digital or analogue data can be transmitted over a communication medium to one or more devices, depending on the interfaces in use. There are two important types of data transmission − Baseband and Broadband. Read through this article to understand each type of transmission and the differences between them. What is Baseband Transmission? It is a transmission technology where a single signal is either sent or received through a communication channel such as a cable, in the form of discrete pulses of the single frequency. The frequency of ... Read More

In electrical machines and instruments, an excitation system is the one which receives electrical energy to produce the working magnetic flux. The excitation system is the crucial component every electromechanical energy conversion device such as electric motor. Depending upon the number of input supplies, any electromechanical energy conversion system can be grouped into the following two categories − Singly Excited System Doubly Excited System In this article, we will discuss the major differences between singly excited system and doubly excited system. Let's start with a basic overview of what singly and doubly excited systems are. What is a ... Read More

Both turbocharger and supercharger are used to increase the pressure of atmospheric air before sending it to the engine cylinder. The compressed air increases the amount of fuel to enter into the engine cylinder for combustion, which in turn increases the power of the engine.Basically both turbocharger and supercharger perform the same operation. However, they are different from each other in many ways, which we are going to highlight in this article. What is a Turbocharger? A forced induction system which uses energy of exhaust gases to compress the atmospheric air and sends it to the engine cylinder is known ... Read More

Sensors and transducers are extensively used in the electrical and electronic instruments to measure different physical quantities. However, there are many differences between a sensor and a transducer that we will discuss in this article. But, before getting into the differences, let's get an overview of what sensors and transducers are, so that it becomes easier to understand how they differ from each other.What is a Sensor? A sensor is a device that detects any physical quantity such as pressure, light, heat, temperature, humidity, etc. from the outside environment and responds according to the input to produce a desired output ...
