Introduction DAMPS (Digital Advanced Mobile Phone Service) is a cellular technology that was first made available in the US in the 1980s. It provided voice communication services to users of mobile phones and was the main commercially available cellular network in the US. DAMPS used analogue transmission, which at the time was the industry standard for cellular networks. Later, modern cellular systems took its place, which had a few advantages over analogue ones such as improved call quality, increased capacity, and improved security. DAMPS was developed by the American Telephone & Telegraph (AT&T) business, which at the time ... Read More
Introduction Direct Broadcast Satellite (DBS) transmission technology delivers television and radio signals directly to households and businesses. In order to receive signals from satellites in geostationary orbit, DBS uses smaller dish antennas, often with a diameter of less than a meter. The signals are scrambled, encrypted, and transmitted across a specific frequency band to the receiving antenna, where they are decrypted and shown on the TV. In locations where cable or terrestrial television service is limited or insufficient, DBS systems are popular because they may provide an extensive range of channels, including high-definition content. Internet services and other multimedia ... Read More
Introduction Database Source Name (DBSN) is recognized as a unique identification of (Database Management System (DBMS). When several databases are hosted on a single DBMS, it is used to establish a connection to a particular database. The database name, host name or IP address of the server where the database is hosted, and the port number used to access the database are all included in the DBSN. To connect to databases and perform database activities, it is frequently used in programming languages and applications. Importance of DBSN in database connectivity The Database Source Name, or DBSN, is important ... Read More
Introduction Data Flow Diagram (DFD) is a perspective model of the flow of data through the process by which the user can understand it easily. By this DFD the system is represented graphically and aimed to reach the concept for both computer specialists and non-specialists in the same way. During specification and analysis of the requirements, DFD helps software engineers, users, and customers to work together. What is DFD? The full form of DFD is Data Flow Diagram. It was made popular by Larry Constantine and Edward Yourdon in the late 1970s. The computational base model “Data ... Read More
Introduction Digital Fuel Injection (DFI) system is programmed to precisely enrich the cold-start mixture so that the portion of the fuel that can vaporise at low temperatures is present in enough quantity to create an ignitable mixture (this so-called "front end" of the fuel is primarily a small volatile species called isopentane). The EPA wants the exhaust catalyst to be near to the engine and ready to "light off" as quickly as possible since the remaining gasoline travels through the engine unburned. Adoption of Gasoline Direct Injection (GDI) in favour of traditional port injection is another stage. Atomized ... Read More
Introduction Dual Modem Cards (DMC) enable the use of two cellular modems on a single device. In order to connect to two distinct cellular networks, these cards often employ two SIM cards. This provides redundancy and enhanced dependability for data transmission, particularly in locations with poor network coverage or heavy data traffic. Industrial applications including remote monitoring, fleet management, and machine-to-machine communication often make use of dual modem cards. They may be used to boost network capacity, offer failover functionality, and enhance data transmission dependability. Dual modem cards may save money by allowing customers to choose the best cellular ... Read More
Introduction Digital Millennium Copyright Act (DMCA) is a federal copyright law that was first established in the US in 1998. There weren't many regulations or protections for online content when the internet first got started, but the DMCA changed that by giving copyright owners more control over who can use their work and how. As you know, the internet has two sides, your information instantly becomes available to people all over the world when you share it online using the top website builders and web hosting services, and with that increased visibility, the likelihood that someone may plagiarize or ...

Introduction Data Manipulation Language (DML) is a particular form of SQL (Structured Query Language) used to access, insert, modify, and remove information from systems. DML stands for Data Manipulation Language. The capability it offers is crucial for data management and control since it enables users to alter and edit the data stored in tables. SELECT, INSERT, UPDATE, and DELETE are just a few of the DML commands that let users conduct various actions on the MySQL database entries. Types of DML commands Data within a database may be changed using DML (Data Manipulation Language) commands in SQL. The ... Read More
