How to select ID that starts with certain character using jQuery ?
jQuery is a popular JavaScript library that simplifies the process of traversing and manipulating HTML documents. In web development, one common requirement is to select elements with specific attributes or properties. In this article, we will explore how to select HTML elements whose IDs start with a certain character using jQuery. Use of Selecting ID that starts with certain character Targeting Specific Groups of Elements: When working with a large number of elements, it may be necessary to group them based on a common identifier. By selecting IDs that start with a specific character, you can easily target and ...
Read MoreDifferences between Routine and Process
A routine is said to be a computer program with a set of instructions that is used for the execution of the system program. They allocate or deallocate the memory used after completion of its execution as per instructions given as routine-routine or even functions. The process is termed as the programs that are currently in execution state and utilizes the resources of CPU. Each process undergoes different states like active, new, ready, block, and wait, suspended during its life cycle. Multiprogramming environment is done to the processes which require it, where each process is classified into preemption and non-preemption ...
Read MoreDifference between Supercomputer and Quantum Computer
What is a Computer? A computer is an electric device which is developed by Charles Babbage in 1822. It takes input data from the input devices, stores and process it, and produces output in the output devices. The processing is done by the Central Processing Unit. It is designed to perform various operations and tasks depending upon the instructions provided by a user. It can perform a wide range of tasks including word processing, graphic design, gaming, and internet browsing. Components of Computer Hardware Parts - Parts of a computer system which ...
Read MoreDifference between Primary Distribution and Secondary Distribution Systems
Introduction to Electricity Distribution Electricity distribution refers to the process of distributing the electrical power from generating stations to the consumers. In the first step, electricity is distributed to substations from the generating stations through transmission lines by increasing the voltage level to reduce transmission losses. In the second step, the increased level of voltage is stepped down using the transformers and supplied to consumers by the utility companies. In any industry, more than one voltage level is used for different purposes like 415 V, 690 V, 6.6 kV, and 11 kV. There is a process of voltage conversion ...
Read MoreDifference between Pipe Earthing and Plate Earthing
In electrical power system, electrical earthing is one of the most important concept used to provide safety and protection to both human and equipment. Electrical earthing, also called as grounding, is basically a path of very low-resistance between the electrical equipment/system and the earth surface. The main purpose of electrical earthing in an electrical system is to provide a safe path for leakage electric current to flow into the earth’s conductive surface to reduce the risk of electrical accidents. Therefore, electrical earthing is an efficient and reliable way of protecting electrical equipment, individuals, and premises against electrical faults ...
Read MoreDifference between Step-Index Fiber and Graded-Index Fiber
Optical fiber technology is defined as technology that is capable to transmit information in the form of light pulses with the help of a high-quality glass or plastic material. It looks like a transparent filament. In this article, we will go through optical fiber, its types, and the differences between them. So, let's begin with the definition of optical fiber. What is an Optical Fiber? Optical fiber is thin a thin or flexible glass or plastic material used to transmit information in the form of light. Glass or plastic serves as a medium to allow the passage of ...
Read MoreDifference between Hybrid Electric Vehicle and Electric Vehicle
The automotive industry is undergoing a major revolution in the method we power our vehicle. The hybrid electric vehicle (HEV) and electric vehicle (EV) are at the leading position of this revolution. The fundamental difference between hybrid electric vehicle and electric vehicle is that electric vehicle relies only on electric batteries as energy source, while hybrid electric vehicle uses both fuel and electricity as the energy source. In this article, we will explore the other major differences between hybrid electric vehicle and electric vehicle. But before that let’s briefly get their overview individually. What is a ...
Read MoreBipolar-Output D/A Converters
In digital electronics, a D/A converter, also called Digital-to-Analog Converter, is an electronic device that converts digital signal inputs into analog signal outputs. Depending on the polarity of output signals, D/A converters can be classified into two types namely, Unipolar-Output D/A Converters and Bipolar-Output D/A Converters. A unipolar-output D/A converter can produce only positive analog signals as output, whereas a bipolar-output D/A converter can produce both positive and negative analog signals as output. In this tutorial, we will discuss bipolar-output D/A converts, along with their construction, types, working, advantages, and applications. So, let’s start with the basic definition ...
Read MoreBlock Coding in Digital Electronics
In digital electronics, block coding is a technique of encoding data into a specific format. It is mainly used to detect and correct errors occurred in the information during transmission and storage. This is done by adding a block code of redundant information to the main data. Block coding is mainly employed to create a robust method of data transmission and storage. In the block coding, data is encoded by splitting it into multiple blocks of a fixed size and applying encoding techniques to each of these blocks separately. In block coding, the input data is taken ...
