The Material UI is a library containing various components with different styles and responsive designs. For example, Material UI contains an AppBar component, which we can directly import into the React component and use as a child component of other components. Also, the Material UI library contains different components like buttons, links, tab bars, pagination etc. Furthermore, we can manipulate every component by passing a prop while using the component. For example, we can make an AppBar responsive by passing the respected props. This tutorial will teach us to use the AppBar component in Material UI. Users should install the ... Read More
While working with the forms in React, sometimes we may require to focus on any input. For example, we want to enable the submit button only if the user enters some text in the input field.

ReactJS is a frontend library, so we can use it to create web pages. It’s natural to show data in real-time applications, and the backend manages it. So, whenever React needs data to show on the web page, it gets it from the backend by making API calls. Sometimes, we may require to send data to the backend to store it in the database. For example, we have taken the user’s profile image and need to send it to the backend to store it in the database. In many cases, we require to send single or multiple files to ... Read More
The Menu item component shows users various menu options, and they can select any option from the menu item component. The menu item component in React Js is similar to the element in HTML, or we can say it is a dropdown menu. Also, menu components contain a submenu to show multiple options for any menu item. Developers should use the HTML tag to implement menu item components from scratch. However, many React libraries available on the internet provide pre-designed Menu item components. So, we will use different libraries to build the menu item components below. Use ... Read More
Fibre Channel Protocol (FCP) is a communication protocol designed to provide fast and dependable data transfers between servers and storage devices in storage area networks (SANs). History of FCP FCP was first introduced in the early 1990s as a outcome of a deal between the tech giants among IBM, HP, and Sun Microsystems. The protocol was designed to improve upon the limitations of previous communication protocols used in SANs, such as SCSI, and to enable higher-speed data transfers. How FCP Works As mentioned, FCP is a layered protocol that operates at the transport and session layers of the OSI model. ... Read More

Radio broadcasting has come a long way since its inception over a century ago. From analog to digital, radio broadcasting has evolved to provide listeners with high-quality audio that can be received on a variety of devices. One of the latest advances in radio broadcasting is Digital Audio Broadcasting (DAB), a technology that is changing the way we listen to radio. What is DAB? DAB is a digital radio broadcasting system that uses digital audio compression to transmit audio signals over the airwaves. Unlike traditional analog radio, DAB offers higher quality audio and a wider range of features, such as ... Read More
Spread Spectrum Communication, a technique used to enhance the reliability and security of wireless transmissions. Spread spectrum communication involves spreading a signal over a wide range of frequencies, which makes it difficult for unauthorized users to intercept or jam the signal. This technique employs different methods to spread the signal, including direct sequence spread spectrum (DSSS) and frequency hopping spread spectrum (FHSS). DSSS multiplies the original signal with a random sequence of bits, known as a spreading code, to spread the signal over a wide range of frequencies. On the other hand, FHSS hops the signal between different frequencies over ... Read More
