    Why Study Software Engineering?

    • Software engineering is a challenging and rewarding field but it can be difficult.
    • Understanding software engineering principles and techniques is critical for successful software development.
    • The goal of studying software engineering is to build efficient and high-quality software.

    Why Do Software Development Projects Fail?

    • Software development projects can fail due to poor planning and management.
    • Unclear requirements and inappropriate development methodologies can lead to project failure.

    What is Software Engineering?

    • Software Engineering is a systematic approach to software development.
    • It is a process that involves activities such as specification, development, validation, and evolution.

    What is Program or Software?

    • A program is a set of instructions that are executed by a computer
    • Software is a collection of programs and data that provide specific functions.

    Client-Server Architecture

    • The internet is a client-server architecture, where a client (e.g., a computer, smartphone, tablet) sends a request to a server (e.g., a web server, database server) and the server sends back a response.
    • The internet is a network of interconnected computers that allows users to access and share information through a variety of applications and services.

    The World Wide Web

    • The world wide web is the collection of web pages and resources that are accessible through the internet.
    • Users can access web resources through hyperlinks and web browsers.

    How the Internet Works

    • The internet uses different protocols, including DNS, IP, TCP/IP, and HTTP, to route and transfer information between computers.
    • Information is sent through fiber optic cables and satellite networks.
    • The internet has a complex infrastructure of networks and data centers

    What is a URL?

    • A URL (Uniform Resource Locator) is a web address that identifies a specific resource available on the internet.
    • A URL includes a scheme (e.g., http, https), a domain name (e.g., youtube.com), a subdomain (e.g., www), a path to the resource (e.g., /results?), and parameters (e.g., search_query=funny+cat+videos).

    What is DNS?

    • DNS (Domain Name System) is the internet's phonebook, it maps human-readable domain names (e.g., youtube.com) to numerical IP addresses (e.g., 172.217.168.14).
    • Different types of DNS servers serve different purposes, including recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers.

    What is HTTP?

    • HTTP (Hypertext Transfer Protocol) is an application layer protocol that is used to fetch resources from the web.
    • HTTP works on top of TCP/IP, using its rules of routing and addressing to send and receive data between devices.
    • HTTP uses methods, such as GET, POST, PUT, DELETE, to interact with web resources.

    What is TCP/IP?

    • TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols that provides the foundation for the internet and its applications.
    • TCP/IP handles packet routing, addressing, and transport across the internet.

    What is the difference between TCP and UDP?

    • TCP (Transmission Control Protocol) provides a reliable, connection-oriented transport layer. UDP (User Datagram Protocol) provides a connectionless datagram-based transport layer.
    • TCP is used for applications where reliable and ordered data delivery is required, while UDP is used for faster and less reliable data transmission, such as streaming audio and video.
