Introduction to DCF In fibre optic communication systems, dispersion compensating fibre (DCF) is an optical fibre used to lessen the phenomena that result in signal distortion and spreading over long distances. By using a fibre with a dispersion opposite to that of the transmission fibre, DCF is intended to account for chromatic dispersion, the most prevalent type of dispersion. It is applied to optical communication systems to boost bandwidth and range. DCF is a crucial component of high-speed communication networks, notably in long- and ultra-long-haul optical transmission systems. DCF Working Principle To take into account the dispersion that happens ... Read More

Introduction Distributed Computing Environment (DCE) refers to a software technology that delivers a framework for designing and executing dispersed applications in networked computing environments. During the 1980s and 1990s, the Distributed Computing Environment was developed by DCE by the Open Software Foundation (OSF) as a collection of standards and technologies for building distributed computing systems across various hardware, operating systems, and network environments. DCE has developed over the years, and its standards and technologies have been incorporated into diverse other distributed computing frameworks and technologies. Architecture of DCE The architecture of DCE (Distributed Computing Environment) depends on ... Read More

Introduction Downstream Channel Descriptor (DCD) is a word used in the telecommunications and networking industries. DCD is a crucial factor in a cable modem network that influences the properties of the downstream channels. The Downstream Channel Descriptor gives details about the downstream channel's maximum and lowest frequencies, as well as the modulation scheme, symbol rate, and other crucial factors. The cable modem termination system (CMTS) transmits the DCD, which the cable modems receive and use to configure the downstream channel. Overview of Downstream Channel Descriptor (DCD) An essential element of cable modems that enables high-speed internet connections is the downstream ... Read More

Definition and Explanation of Direct Current Direct current (DC) is an electric current that flows in a single direction, with a consistent voltage and amplitude. Unlike alternating current (AC), which intermittently inverts direction, DC maintains a consistent polarity. It is regularly produced by batteries, generators, and electronic control supplies.                         DC is broadly utilised in electronic devices, such as computers, smartphones, and televisions, as well as in a range of industrial applications, including electroplating, electrolysis, and welding. It is additionally utilised for high-voltage power transmission over long distances, ... Read More

Introduction to DAST Dynamic Application Security Testing (DAST) is a type of security that focuses on identifying vulnerabilities and weaknesses in the dynamic or runtime behaviour of web applications, APIs, and other software applications. DAST involves actively testing the application while it is running to simulate the real-world attacks and evaluate its security posture. This type of testing involves sending various inputs and requests to the application and analysing the responses to uncover security flaws such as SQL injection, cross-site scripting (XSS), and other common web application vulnerabilities. Features and process of DAST The features and process of ... Read More

What is Direct Attached Storage (DAS)? Direct Attached Storage (DAS) refers to a type of storage architecture in which storage devices, such as hard drives or solid-state drives, are connected directly to a computer or a server, typically using a high-speed interface. In DAS, the storage devices are not networked or shared with other systems, and the storage capacity is directly available to the host system that the devices are connected to. Types of Direct Attached Storage (DAS) There are several types of Direct Attached Storage (DAS) configurations including − Internal DAS − In this configuration, ... Read More
