    Study Notes

    Computer Network Topologies

    • A network topology defines the layout of the network connections and devices.
    • The most popular topology in network implementation is star topology, but there are other topologies with their advantages and disadvantages, such as bus, ring, mesh, and hybrid.
    • Bus topology is a simple and cost-effective linear connection of nodes with a single communication cable.
    • Ring topology is a closed loop where nodes are connected in a circular fashion with data flowing in one direction.
    • Star topology is a centralized structure with all nodes connecting to a central hub, switch, or a central computer.
    • Mesh topology is fully interconnected, where each node has a dedicated connection to all other nodes, providing high reliability and fast communication.
    • Hybrid topology combines different topologies to leverage their strengths and address specific requirements within a network.

    Client-Server Model

    • The client-server model is a network architecture where clients request services from a server.
    • Clients do not share resources, and examples of the model include email and the World Wide Web.
    • Clients send data requests to servers. Servers accept the request, process it, and deliver the data back to the client.

    File Server

    • A file server is a dedicated computer that manages and stores data files for users on a network.
    • File servers offer central storage space, enabling convenient file sharing and access.
    • Features of file servers include file sharing, authentication, and access control.
    • Advantages of file servers include centralized data management, security, and backup capabilities.

    Web Server Architecture

    • Web server architecture defines how web servers handle requests and deliver web content.
    • Common web server softwares include Apache, Nginx, Microsoft IIS, and LiteSpeed.
    • Web servers receive requests from clients, process them, and send back responses.
    • Web servers can be used to host websites, web applications, and online services.
    • Web servers provide features such as security, authentication, and static content delivery.
