Both cell and battery are the sources of electrical energy in any electrical circuit that provide necessary excitation to the circuit. The cell and battery always deliver electric power to the circuit in the form of direct current (DC), they can never deliver alternating current (AC). Therefore, in practice, the cell and battery are the primary sources of direct current (DC) electricity. However, the working principle of both cell and battery is the same, i.e. electrochemical reactions where the electrical energy is converted into chemical energy and vice-versa. In this article, we will compare cell and battery by considering ... Read More

Both capacitor and supercapacitor are passive circuit components that store electrical energy in the form of electrostatic charge. Thus, the primary function of capacitor and supercapacitor is the same, i.e., storage of electric charge. However, there are many difference between a capacitor and a supercapacitor.In this article, we will discuss the key differences between capacitor and supercapacitor by considering various parameters such as definition, construction, types, energy density, etc. But before that we should learn the basics of capacitor and supercapacitor so that it becomes easier to understand the differences.What is a Capacitor?A capacitor is a two terminal passive circuit ...

People who are just starting out on the web often say that they have trouble identifying the difference between HTML 5 and XHTML. There is sometimes a lack of clarity on which of these languages is best for a beginner. It is not surprising that such misunderstanding continues to exist, given that both XHTML and HTML 5 serve, more or less, the same purpose.Go through this article to get an overview of XHTML and HTML 5 and learn how these two markup languages differ from each other.What is XHTML?XHTML stands for EXtensible HyperText Markup Language. The Internet has advanced to ... Read More

Today, gaining access to the Internet does not need signing up for the data subscription plan offered by the Internet Service Provider (ISP). There are other available choices. The Internet can be accessed and shared in a variety of other ways, thanks to our smartphones.WiFi and hotspot are two terms that are sometimes used interchangeably to refer to connection to the Internet; however, there is a significant difference between the two. Hotspots are physical locations that are typically public places that are served by an access point that is used to connect devices to one another using WiFi. WiFi is ... Read More

There are two distinct varieties of digital computer architectures, each of which provides a description of the functioning and execution of computer systemsThe first is known as the Von Neumann Architecture, which was designed by the well-known physicist and mathematician John Von Neumann in the late 1940s.The second is known as the Harvard Architecture, which was based on the original Harvard Mark relay-based computer and used separate memory systems to store data and instructions. Both of these computer architectures were developed in the 1950s.In the original Harvard architecture, data and instructions were both stored in electro-mechanical counters, while the instructions ...

JavaScript makes webpages interactive. JavaScript with HTML and CSS improves webpage functionality. JavaScript validates forms, makes interactive maps, and displays dynamic charts. The JavaScript engine in the web browser runs the JavaScript code when a webpage is loaded, which is after HTML and CSS have been downloaded. The HTML and CSS are then changed by the JavaScript code to update the user interface on the fly.JavaScript code is run by a program called the JavaScript engine. At first, JavaScript engines were built like interpreters. Modern JavaScript engines, on the other hand, are usually built as just-in-time compilers that turn JavaScript ... Read More

JavaScript provides three mechanisms for storing data on the client − cookies, session storage, and local storage. Each one has advantages and disadvantages.Local storage is the most recent mechanism. It allows for larger amounts of data to be stored, but the data is not deleted when the browser is closed. Local storage is useful for storing data that the user will need to access later, such as offline data.Session storage is similar to cookies, but the data is only stored for the current session. This means that the data will be deleted when the user closes the browser. Session storage ... Read More

Function.prototype.apply and Function.prototype.call are methods that allow you to call a function with a specific this value and arguments. The main difference between the two is that apply lets you pass in an array of arguments, while call requires you to list the arguments one by one.Function.prototype.applyFunction.prototype.apply is a method that allows you to call a function with a specific this value and an array of arguments.SyntaxThe syntax for using apply is −func.apply(thisArg, argsArray)Here thisArg is the value that will be used as this inside the function. argsArray is an array of arguments that will be passed to the function.ExampleHere’s ...

Technology is something that has a significant impact on each and every one of our lives. Due to the large number of devices that we all interact with on a daily basis, we are exposed to a wide variety of software. We are able to complete a variety of tasks with the assistance of software.Software is an essential component that grants its users the ability to operate and carry out any designated activity. The difference between open-source software and proprietary software is a significant one in the software industry. Read through this article to find out how an open-source software ... Read More

There are many different coding languages that can be used when designing websites; some of these languages are more difficult to learn than others. HTML, JavaScript, PHP, CSS, Ruby, Python, and SQL are some of the most widely used languages for developing websites.To comprehend the fundamentals of web design and development, however, all you need to know is HTML and JavaScript, the two key programming languages. Each of these serve a unique function on the web. Since HTML and JavaScript act as the foundation of any website, you need to know how they will affect your website and what they ... Read More
