Know the fundamentals of software or application development from scratch. Before you begin your career as a developer reading this article will help you navigate the learning steps properly.
Introduction
Software or application is a set of instructions or programs that tell a device what to do and how to do it according to the given commands or instructions. It is non-tangible, unlike hardware, such as the physical components of a PC, TV, or setup box. The software helps the user interact with a device such as playing games, controlling the TV, editing videos, creating videos, and more.
Types of Software
Software can be broadly categorized into several types based on its functionality and purpose. Here’s an overview of the main types of software:
Embedded Software
A type of software designed to control the functions of devices that aren’t generally considered computers.
Example: WebOS – a Linux-based operating system (OS) that’s embedded in smart devices, such as LG TVs
Firmware
A type of embedded software that runs on a hardware device’s flash memory chip and acts as a bridge between the hardware and the operating system. Firmware is responsible for low-level tasks like starting up the hardware, communicating with other devices, and performing basic input/output tasks.
Example: BIOS of a PC
Where you can find the firmware applications.
- Personal Computer
- Storage Devices
- Mobile Devices
- Automotive Devices
- Home Appliances
- Smart Cards
System Software
Manages and controls computer hardware so that application software can function.
Examples: Operating Systems (e.g., Windows, macOS, Linux), utility software (e.g., disk management tools).
Application Software
Designed to perform specific tasks for users.
Examples: Web browsers, word processors, spreadsheets, media players, and games.
Middleware
Acts as a bridge between system software and applications, facilitating communication between different software components.
Example: Database middleware, message brokers.
Programming Software
Tools that developers use to write, test, and debug other software.
Examples: Code editors, compilers, interpreters, and debuggers.
Characteristics of Software:
- Intangible: It cannot be physically touched.
- Customizable: Software can often be modified or updated to meet specific user needs.
- Dependent on hardware: Requires hardware to function but can be deployed across different hardware platforms.
- Upgradable: Can be enhanced over time through updates and patches.
Common Examples of Software:
- Operating Systems: Linux, Windows, macOS.
- Productivity Tools: Microsoft Office, Google Workspace.
- Web Applications: Social media platforms, online banking systems.
- Games: Minecraft, Call of Duty.
Application Development
Application development is the process of creating software applications that run on various devices, such as computers, mobile phones, and tablets. It involves several stages and can range from developing simple apps for personal use to complex enterprise-level applications.
There are different types of applications to develop. I am listing the three main types.
- Desktop Applications
- Web Applications
- Mobile Applications
Desktop Application
A desktop application is a type of software that is designed to run on a personal computer or workstation. These applications are typically installed directly onto the operating system of the computer and can be launched from the desktop or a start menu. Here are some key characteristics of desktop applications:
- Local Installation: Desktop applications are installed locally on a computer’s hard drive.
- Offline Capabilities: They can often be used without an internet connection, though some may require connectivity for certain features.
- User Interface: They generally have a graphical user interface (GUI) that allows users to interact with the software using visual elements like windows, buttons, and menus.
- Performance: They can take full advantage of the computer’s hardware capabilities, often resulting in better performance for resource-intensive tasks.
- Examples: Popular examples of desktop applications include Microsoft Word, Adobe Photoshop, VLC Media Player, and games like The Sims.
Web Application
A web application is software that runs on a web server and is accessed through a web browser over the internet. Unlike desktop applications, which are installed on a local computer, web applications are hosted on remote servers and can be used on any device with a web browser. Here are some key features of web applications:
- Accessibility: Web applications can be accessed from anywhere with an internet connection, on various devices like desktops, laptops, tablets, and smartphones.
- Platform Independence: They are typically platform-independent, meaning they can run on any operating system (Windows, macOS, Linux, etc.) as long as the browser is supported.
- No Installation Required: Users don’t need to install anything on their devices; they simply open a browser and navigate to the web application.
- Easy Updates: Updates are applied on the server side, so users always access the most recent version of the application without needing to download updates.
- Examples: Common examples include email services like Gmail, social media platforms like Facebook, online banking, e-commerce sites like Amazon, and productivity tools like Google Docs.
Mobile Application
A mobile application, or mobile app, is software designed to run on mobile devices such as smartphones and tablets. Here are some key characteristics of mobile applications:
- Platform-Specific: Mobile apps are typically developed for specific operating systems, such as iOS for Apple devices and Android for devices from various manufacturers.
- Touch Interaction: They are optimized for touch screen interfaces, providing intuitive and interactive experiences through gestures, taps, and swipes.
- Download and Installation: Mobile apps are downloaded and installed from app stores like Apple’s App Store and Google Play Store.
- Native and Hybrid Apps:
- Native Apps: These are developed for a specific platform using platform-specific programming languages (e.g., Swift for iOS, Kotlin for Android) and provide the best performance and user experience.
- Hybrid Apps: These are developed using web technologies like HTML, CSS, and JavaScript, and then wrapped in a native container. They can run on multiple platforms with a single codebase.
- Offline Capabilities: Some mobile apps can function without an internet connection, though many require connectivity for full functionality.
- Examples: Popular examples include social media apps like Instagram, messaging apps like WhatsApp, banking apps, gaming apps like Candy Crush, and productivity apps like Evernote.
Programming languages for developing different types of applications
Choosing the right programming language depends on the type of application you want to develop. Here’s a breakdown of some common programming languages and the types of applications they are best suited for:
Desktop Applications
- C#: Ideal for Windows applications using the .NET framework.
- Java: Great for cross-platform applications, thanks to its platform-independent nature.
- Python: Useful for developing simpler desktop applications with libraries like Tkinter or PyQt.
- C++: Preferred for high-performance applications and games.
Web Applications
- JavaScript: Essential for front-end development (along with HTML and CSS). Frameworks like React, Angular, and Vue.js enhance its capabilities.
- Python: Popular for back-end development with frameworks like Django and Flask.
- Ruby: Known for its elegant syntax, used with the Rails framework for web development.
- PHP: Widely used for server-side scripting and back-end development.
- Java: Also used for building large-scale enterprise web applications.
Mobile Applications
- Swift: The go-to language for developing iOS applications.
- Kotlin: Preferred for Android application development.
- Java: Also used for Android applications, though Kotlin is now the preferred language.
