Application Development is a complex process that involves various activities such as designing, coding, and building software applications. In fact, the process can be broadly classified into two categories, namely Mobile Applications and Web Applications. These two categories differ in their accessibility and usage. For instance, Web Applications are primarily accessed via web browsers and can be used on any device with an internet connection. In contrast, Mobile Apps are specifically designed for mobile devices such as smartphones or tablets.

When it comes to Web Applications, there are two types: native and hybrid. Native applications are built using a programming language that is tailored to a specific platform, whereas hybrid applications utilize a combination of technologies and frameworks to deliver an app-like experience on the web. The technologies employed include HTML5, CSS3, JavaScript, and several open-source technologies.

On the other hand, Mobile Applications are designed using a single programming language, like Swift for iOS development or Java for Android development. However, if a framework like PhoneGap is used, Mobile Apps could be hybrid and run on both operating systems. Whatever the case, Application Development is a crucial aspect of software development that requires meticulous attention to detail and a deep understanding of the target users and their needs.
