The 3rd generation of computers introduced the concept of multiprogramming. In 1968, this concept came into existence. Before, there was no such multitasking performance given by computers. Computer systems would perform a single task at a time. This would be a time-consuming and hectic process. In uni-programming systems, if the processor is busy performing one … Read more
The communication system is a very important part of our lives. One can talk to and see others from anywhere in the world. As the communication system evolved, cheaper and more efficient ways of communication became available for us. Depending on the mode of transmission of signals, the communication system can be divided into two … Read more
A very interesting topic of data structures is “Search”. Now, let us first understand what you mean by search in non-technical terms. Search simply means to find the particular element or thing. We often search for lost things or unordered things. For example, I cannot find my blue pen on the study table. I searched … Read more
DIAC and TRIAC are two power semiconductor devices that are able to operate in high voltage and current. Both of them belong to a thyristor family. Both of these components have a p-n-p-n structure. But they are different in many ways. In this article, we are going to discuss what is the difference between DIAC … Read more
Relays and circuit breakers are two commonly used terms of a power system. The study of the protection in power systems is incomplete without the study of relays and circuit breakers. The uses of relays and circuit breakers are found in industrial as well as in commercial applications. There are many differences between a relay … Read more
The name hardware and software are closely related to the computer world. None of us from the technical field have ever missed these terms. It’s good and important to know how they differ from each other. The computer hardware is any physical component of your computer. Whereas, computer software is the systematic code and instruction … Read more
Cell and battery both are electrical devices that are used to store chemical energy and then that stored chemical energy is transformed into electrical energy. Cell and battery are direct voltage sources that produce a continuous direct output voltage. Cells and batteries are electrochemical devices that use a chemical reaction to generate electricity. The major … Read more
The words work and power might seem similar to each other as they both involve energy but they are not the same. Work is the amount of energy required to move an object from one point to the other or work is said to be done when a force displaces an object in the direction … Read more
Valence band and conduction band are two different types of energy levels that are separated by some amount of energy. The basic difference between conduction band and valence band is that in the conduction band the electrons which take part in the process of conduction exists while in the valence band the electrons are present … Read more
In electronics, based on the direction of current flow, the elements or the components can be classified into two categories – bilateral and unilateral. The element that lets current pass through it in both directions i.e., the current does not depend on the polarity of the applied voltage, is called a bilateral element; for example … Read more
