TFT (thin film transistor) and QVGA (quarter video graphics array) are two display screen technologies. While TFT is a type of technology used to make displays, QVGA is a display resolution. TFT is a display technology that allows for high-quality images, whereas QVGA is a particular resolution used in displays that is commonly found in small devices such as mobile phones. Read this article to find out more about TFT and QVGA and how they are different from each other. What is TFT? TFT is an abbreviation for thin film transistor, a form of technology used in the production ... Read More
Sheetrock and drywall are types of building material made up of gypsum plaster layered between two layers of paper. Sheetrock is actually a trademark name for a type of drywall produced by the USG Corporation. Drywall is a general name for any board made of gypsum plaster Read this article to find out more about Sheetrock and Drywall and how they are different from each other. What is Sheetrock? Sheetrock is a drywall trademark that has become synonymous with the material itself, much like Kleenex and tissue paper. It is a form of building material made of gypsum plaster, which ... Read More
Sempron and Athlon are both CPU (Central Processing Unit) product lines manufactured by AMD (Advanced Micro Devices); however, they differ significantly. Sempron is an AMD (Advanced Micro Devices) budget CPU product line designed for cost-conscious users who do not require high-performance computing. Athlon CPUs often feature more cores than Sempron CPUs, which can boost performance for tasks that benefit from numerous cores. Read this article to find out more about Sempron and Athlon and how they are different from each other. What is Sempron? Sempron is an AMD (Advanced Micro Devices) budget CPU product line designed for cost-conscious users who ... Read More
The digital modulation techniques QAM (Quadrature Amplitude Modulation) and ATSC (Advanced Television Systems Committee) are used in communication systems. QAM and ATSC are both used in digital television transmission, but in different contexts. ATSC is used for over-the-air broadcast, whereas QAM is used for cable television transmission. QAM can also be used in other applications, such as satellite and wireless communication networks, whereas ATSC is mainly used for television broadcasting. Read this article to find out more about QAM and ATSC and how they are different from each other. What is QAM? Quadrature Amplitude Modulation (QAM) is a digital modulation ... Read More
In telecommunication systems, pulse and tone are two different kinds of signals. Tone signals are analogue signals represented by a continuous waveform, whereas pulse signals are digital signals represented by a sequence of on/off pulses or voltage levels. Read this article to find out more about Pulse and Tone and how they are different from each other. What is Pulse Dialing? In telecommunications systems, pulse refers to a way of signal transmission that involves sending electrical pulses down the telephone line. This method, also known as pulse dialing, is widely used in older systems for dialing telephone numbers. In pulse ... Read More

This guide aims to show how to implement file uploading using Angular. File uploads are a crucial component for many websites, allowing users to transfer files from their devices to the server. Whether it be for storing user-generated content, sharing files with others, or downloading files from the server, file uploads play a significant role. Steps for File Uploading with Angular Configuring the File Upload Before diving into the actual file upload implementation, we must first set up the necessary file upload configuration. This involves specifying the server-side script URL that will handle the upload, as well as any additional ... Read More
TypeScript is a popular typed superset of JavaScript that compiles down to plain JavaScript. It offers numerous features to improve the overall developer experience, such as static typing, interfaces, and namespaces. One key feature in TypeScript is the noImplicitAny compiler option. In this article, we will explore noImplicitAny, its benefits and drawbacks, and two different approaches to deal with it in your TypeScript code. Approach 1: Explicit Type Annotations This approach involves adding type annotations to every variable and function parameter, ensuring that the compiler knows the expected types. Adding Type Annotations function add(a: number, b: number): number { ... Read More
Introduction Calling web services is one of the most commonly used services over the web. It refers to the way of communicating with the software systems. This communication can be between the clients with the server, peer-to-peer, etc. HTML5, the latest version of HTML, provides A LOT OF WAYS LIKE XMLHttpRequest object, APIs like Axios and fetch, WebSockets, etc. This API allows the users to get dynamic static, real-time, or dynamic content depending upon the requirement. In this article, we shall learn how to call web services by using different methods like calling APIs, web sockets, etc. XMLHttpRequest is a ... Read More
