Introduction to Web and Application Development

What is Web Development?

Web development is the process of creating, designing, and maintaining websites and web-based applications. This involves coding the structure, features, and interactive elements of a website. Web developers typically focus on three core areas:

Front-End Development

• Focuses on the visual and interactive parts of a website that users see and interact with.
• Relies on foundational technologies like HTML, CSS, and JavaScript.
• Aims to deliver seamless and intuitive user experiences.

Back-End Development

• Manages the back-end development operations, such as server management, databases, and application logic.
• Employs languages such as Python, Ruby, PHP, and Java.
• Ensures that websites function smoothly and securely.

Full-Stack Development

• Integrates both front-end and back-end capabilities.
• Provides end-to-end solutions, allowing developers to handle all aspects of website creation.

What is Application Development?

Application development involves designing and building software programs for various platforms, including mobile devices, desktop systems, and web environments. These applications serve multiple purposes, such as enhancing productivity, enabling communication, or offering entertainment.

Types of Applications

• Mobile apps: Developed for smartphones and tablets on operating systems like iOS and Android.
• Desktop apps: Created for computers and laptops running Windows, macOS, or Linux.
• Web apps: Accessed via internet browsers, combining the features of both websites and software.

Programming languages used are:

• Swift and Objective-C for iOS development.
• Kotlin and Java for Android programming.
• C# and .NET for Windows-based applications.
