The opportunities came in two phases. Firstly, everyday life shut down globally, and all the action shifted online. What a mighty break it presented to online businesses with the work-from-home culture! Suddenly, the whole world went online, working, searching for recreation, hobbies, games, and training programs to fill the vacant hours. Programmers and software engineers, the video industry, and social media had ... Read More
Both operating system and Kernel are types of system software. The basic difference between the two is that an operating system is a system software that acts as the interface between the users and the machine, while a kernel is a part of the operating system that converts user commands into machine language. Read through this article to find out more about operating systems and kernels and how they are different from each other. What is an Operating System? Operating System manages a computer and acts as an interface between user and computer. Operating system is the first program that ... Read More
A program is a passive entity that has a set of codes and instructions required to accomplish a task. A process, on the other hand, is an active entity of a program that is started with the execution of the program. Thus, the process is started by the program, once it is executed. The instructions of the program are then executed by the process. Read through this article to find out more about programs and processes and how they are different from each other. What is a Program? A program is a set of instruction codes that has been designed ... Read More
The terms "product" and "process" are important in the context of software development. The basic difference between a product and a process is that a process is a set of steps to guide the project in order to obtain the appropriate product, whereas the product is the final result of the software project. In this article, we will discuss more about "product" and "process" and how they are different from each other. What is a Product? In software engineering, any software developed as per the requirements of the client is referred to as a product. In other words, a product ... Read More
Both Procedural and Non-procedural Languages are widely used in the development of applications and other computer software. Both these types of languages have different approaches on the basis of which we can differentiate them. In this article, we will discuss the important differences between procedural and non-procedural programming languages. Let's start with some basics of procedural and nonprocedural language. What is a Procedural Language? Procedural languages are command-driven or statement-oriented programming languages. A program written using a procedural programming language includes a sequence of statements, and the implementation of each statement generates the interpreter to modify the value of one ...

A projector is a visual display unit that is used to project pictures and films onto a screen. Depending on the technology used, several types of projectors available such as LCD projector, LED projector, DLP projector, 4K Projector, Laser projector, etc. In this article, we will discuss about DLP and LCD projectors, and how they are different from each other. The basic difference between the two is that DLP projectors use a series of mirrors placed on a microchip that act as pixels, whereas LCD projectors use liquid crystals placed between two transparent electrodes and two polarizing filters. What is ... Read More
In operating systems, both deadlock and starvation are unwanted situations that take place when the processes that need a shared resource block each other's progress indefinitely. Both are unwanted situations; however, a deadlock is quite different than a starvation. In this article, we will discuss all the important differences between deadlock and starvation. What is Deadlock? A deadlock is a condition in operating systems in which no process proceeds for execution and waits for resources that have been acquired by some other processes. Thus, in the case of a deadlock condition, the process simply gets blocked. Deadlock is also known ... Read More
You might have come across situations where you need to add common words at the end or beginning of a range of cells in Excel. It can be a time-consuming process if you decide to do it manually. In such cases, you can use the concept of suffix and prefix in order to complete the process very easily. Read through this article to find out how you can add prefix or suffix to a range of cells in Excel in an efficient manner. How to Add Prefix to a Range of Cells? Let us see a simple process to add ... Read More
In this article we are going to discuss how to perform shallow copy on JavaScript objects. If the source value is the reference to an object, then it will only copy the reference value into the target value. When the source properties are copied without reference and there exists a source property whose value is an object and is copied as a reference. A shallow copy constructs a new compound object and then (to the extent possible) inserts references into the objects found in the original. Using the _.extend() method Underscore.js are a library of JavaScript and has a method ... Read More
In this tutorial, we will learn if it is possible to write data to files using only JavaScript. JavaScript has a library named fs (short form of File-System) that manages all writing operations. It is a JavaScript program (fs.js) with functions for writing operations. Utilize functions to write text to system files by importing the fs module into the program. For example, the writeFile() function will erase all old data from a file and create a new one with the specified name if there isn’t already one. It is mainly used for writing operations. The File-System module is a handy ... Read More
