    Study Notes

    Issues with Client/Server Models

    • Traditional client/server setups face issues with unpredictable workloads, making them less agile and versatile compared to peer-to-peer systems.
    • Peer-to-peer systems can solve problems like managing unpredictable workloads and securing against DDoS attacks and similar cyber attacks.
    • Peer-to-peer systems are also helpful in handling disruptions based on a single point of failure.

    Two-Tier Architecture

    • A two-tier architecture is a software architecture that separates the presentation layer (client) and data layer (server).
    • HTTPS enables website encryption by running HTTP over the Transport Layer Security (TLS) protocol.
    • HTTPS ensures secure communication between the client and server, but it does not protect against other types of attacks like cross-site scripting and injection.

    FTP Server

    • An FTP server is a computer that allows users to upload and download files using the File Transfer Protocol (FTP).
