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 ...

A cell is an active circuit component that supplies electrical energy to the circuit. A cell stores the energy in the form of chemical energy and converts it into electrical energy when the load is connected across its terminals. Depending on the ability to recharge, the cells are classified into the following two types, viz. − Primary cell Secondary cell Read through this article to find out more about primary cells and secondary cells and how these two types of cells are different from each other. What is a Primary Cell? The type of electric cell which produces electrical ... Read More

A turbine is a device which converts the energy of some fluid into rotational mechanical energy. There are a number of turbines available based on the type of input used such as steam turbine, water turbine, gas turbines, etc.The most commonly used water turbines are Pelton wheel, Francis turbine and Kaplan turbine. Go through this article to find out the major differences between Pelton wheel and Francis turbine. What is Pelton Wheel? A Pelton wheel is an impulse type water turbine in which the entire pressure of water is converted into kinetic energy in a nozzle and the velocity of ... Read More

A control system is defined as the mechanism or a system that provides the desired response or output by controlling the input and processing system. These days, control systems are being implementing in every smart devices and systems such as traffic lights system, washing machine, rocket launching systems, electrical power system, etc. Depending on the feedback path present in the system, the control systems can be classified into following two types, viz − Open Loop Control System Closed Loop Control System In this article, we will discuss all the major differences between open loop and closed loop control ...

A type of internal combustion engine which converts the energy of natural gas or other fuel gas into mechanical rotational energy is called a gas turbine. In simple words, a gas turbine is a type of turbine that driven by expanding hot gases produced by the combustion of fuel gas. The gas turbines are broadly classified into two types, viz − Open cycle gas turbine Closed cycle gas turbine This article provides a comprehensive understanding of differences between open cycle gas turbine and closed cycle gas turbine by considering various parameters such as basic definition, working fluid, heat ...

An electric circuit or simply circuit is an arrangement of circuit components such as energy sources, resistors, inductors, capacitors, etc. which allows the flow of electric current from source to load. Based on the ON & OFF condition of the circuit, it can be of two types viz − Open Circuit Closed Circuit In this article, we will discuss the key differences between open and closed circuits. But, before discussing the difference, let's get a basic overview of what open and closed circuits are, which will help in understanding their differences better. What is an Open Circuit? When ...
