    The physical or logical organization of a computer network is referred to as network topology. It specifies how connections are made and how information is passed between devices. A popular network architecture in computer networks is the star topology.

    All network nodes in a star topology are linked to a single hub or switch that serves as the network's focal point. Every piece of equipment, including PCs, printers, and servers, has a unique, dedicated connection to the hub. The central hub serves as the network's command center and is the conduit via which all data transmission travels.

    • Using pre-established security rules, a firewall is a network security device that monitors and regulates both incoming and outgoing network traffic. The network is shielded against unauthorized access and potential dangers by acting as a barrier between internal and external networks.
    • Networking equipment that passes data packets between computer networks is a router. It serves as a bridge across several networks and chooses the most direct route for data depending on addressing and network protocols.
    • Using a modem, a computer or network may communicate with an Internet service provider (ISP) through a particular kind of communication line, such as phone lines or cable lines, by modulating and demodulating digital signals.

    5. Which one is an illustration of a programming paradigm of the following?

    a) Object-Oriented Programming

    b) Database Management System

    c) Graphic User Interface

    d) Web Browser

    Ans: a: Object-Oriented Programming

    A programming paradigm is a method or fashion of programming that outlines the organization, ideas, and guidelines followed when creating computer programs. It offers a structure for resolving issues and planning code. There are several programming paradigms, and each one has a unique approach and set of guidelines.

    • A programming paradigm known as object-oriented programming (OOP) centers on the idea of objects. It places a focus on the division of code into reusable objects that contain data and behaviours. In object-oriented programming (OOP), objects are instances of classes, and they communicate with one another via methods, which are functions specified inside the class.
    • A programming paradigm is not demonstrated by the database management system (DBMS). Users may effectively save, retrieve, and change data with this software system, which manages databases. Although DBMSs offer features like data organization, query processing, and concurrency management, they do not impose any specific paradigm for programming.
    • Also, not a programming paradigm is the graphic user interface (GUI). It speaks about the visual user interface that allows people to interact with software or a computer. To simplify user input and output, GUIs include buttons, menus, windows, and other graphical features. Although GUIs are frequently used in programming, they are rarely thought of as a paradigm in and of themselves.
