A multiplexer (MUX) is a digital combinational logic circuit that accepts multiple data inputs and allows only one of them at a time to transmit over an output channel. A multiplexer consists of 2n input lines, n select lines, and one output line. In a multiplexer, the routing of the desired data input to the output channel is done by the logic level applied to the select lines. The functional block diagram of a multiplexer is shown in Figure-1. This article is primarily meant for explaining the design procedure of different types of multiplexer circuits. More specifically, here we ... Read More
What are Twitter Cards? Twitter cards refer to a media-rich snippet, including visual cues for viewers. This is an improved version of a standard tweet. These snippets include images, videos, links, product information, or app download options. Importance of Twitter Cards in SEO Contents with images and interactive features get more interaction in social media. Tweets containing images received 41% retweets and a 55% increase in leads. As you know, Search engines and social media algorithms value engagement and interaction. Twitter has a tie-up with Google. This is why whenever you search for an entity. Search query or individual, you ... Read More
Technical SEO involves practices to optimize the technical elements of a website to rank them in search engines. Site owners often ignore technical SEO. It may be because they don't know how it helps in SEO or find it too hard to follow. In reality, Technical SEO is pretty impactful for SEO and Lead generation. In fact, without it, you don't even have a chance to rank or generate a single lead. Promotes Error-free Link Building Link building is the process of receiving links from other websites. It is a seal of confidence provided by other websites about your content. ... Read More
Read this article to learn how you can use a multiplexer to realize universal logic gates. Let us start with a brief introduction to multiplexers and universal logic gates. What is a Multiplexer? A Multiplexer or MUX or Data Selector is a combinational logic circuit which accepts several data inputs and allows only one of them at a time to pass through the output channel. The block diagram of a multiplexer is shown in Figure-1. A multiplexer consists 2n data input lines, n select lines, and only one output line. The logic level applied to the select lines determine ... Read More
Role of Technical SEO for Travel Websites Travel websites are all about user experience and engagement. However, before you begin working on those parameters, you need to work on making your users land on your website. This means you need to get your site ranked in search engine results pages (SERPs). Once you get exposure in search engine results, your next step is to create the user experience. This can be possible by creating a stellar user experience. Technical SEO is a set of search engine optimization practices that involves identifying and fixing errors that could hamper your website ranking ... Read More
Electrical analogue is basically a way of representing the operation of a logic gate such as OR gate, AND gate, NOT gate, etc. in the form of an electric circuit. In other words, we can represent the operation of a logic gate by using basic circuit components like battery, switches, lamps, etc. So, let us discuss the electrical analogue for each logic gate in detail. OR Gate Electrical Circuit The OR Gate is a type of logic circuit in digital electronics which may have two or more inputs but only one output. A two input OR gate is shown in ... Read More
Technical SEO Recommendations for Optimizing Image Packs for Google Google's official Guidelines state that they expect great user experience from websites. High quality and intelligent image practices are critical to pleasing Google to get featured in image packs of SERP. Follow the SafeSearch Guidelines Before you start anything, you must read the SafeSearch guidelines of Google. Google comes with a filter than blocks explicit content. If your images have any indication related to sexual, violent, or graphic, Google Algorithms might hide them from search results. As a result, it will only be visible when the user turns off their safe ... Read More
What is a Transformer? A transformer is an electrical device whose main function is to transmit alternating current between two circuits at a constant value of frequency, but at varying voltage levels. A transformer is constructed by combining two kinds of coil. The first coil carrying the magnetic flux is called the primary coil, while the second coil placed opposite to it, in which electromotive force (E.M.F) is induced is called as the secondary coil. Figure-1 illustrates a standard representation of a transformer. Input voltage at the primary side of the transformer produces the varying magnetic flux on the primary ... Read More
Force and Power are two important concepts in physics. They might appear similar at first sight, but they are completely different from each other. The most fundamental difference between force and power is that Force is a cause that can change or try to change the state of an object from rest to motion or motion to rest, whereas Power is the term used to express the rate of doing work. Read this article to learn how Force is different from Power. What is Force? Force is an external agent that can change the state of an object either from ... Read More
In this tutorial, we will learn to create an id using mongoose in JavaScript. Users can use the Mongoose NPM package in NodeJS to use MongoDB with NodeJS or connect MongoDB with the application. While storing the data in the MongoDB database, we must add a unique id to every data collection. However, if we don’t add an id, it generates automatically and adds to the data. Syntax Users can follow the syntax below to create an id using mongoose in JavaScript. var newId = new mongoose.mongo.ObjectId(); In the above syntax, we access the ‘mongo’ from the mongoose and ...
