Firmware vs Software – Easy Guide to Understanding The Differences Between The Two

Do you need help understanding the difference between firmware and software? There is no need to worry because many people find these tech terms confusing.

Not knowing what sets them apart can be frustrating, especially when they play such important roles in your devices.

A report shows that 83% of businesses have experienced a firmware attack within the last two years. This indicates a rising trend of attackers exploiting vulnerabilities in firmware, which is often overlooked compared to software.

We’ll break down the key differences between firmware and software so you can confidently grasp what each term means and why it matters to you.

What Is Software?

Software is a set of programs, instructions, or data that tells a computer or device how to operate. It is the digital component that performs specific tasks, ranging from simple calculations to complex functions.

You usually store software on your computer’s hard drive or another storage device. When you open a program, the software loads into your computer’s memory so you can use it.

In contrast to firmware, software is easy to access and user-friendly. You can install, update, or remove it whenever you want, giving you more control over your computer and what it can do.

Software is created using various programming languages, with common examples including Python, Java, and Structured Query Language (SQL). While software serves numerous functions, it generally falls into two main categories: system software, designed for operating systems (OS), and application software, which focuses on user-specific tasks and applications.

Software Key Features

• User Interaction: Software is designed to interact with users through a graphical user interface (GUI), such as icons, buttons, and windows.
• Adaptability: Software can be easily updated, upgraded, or modified to include new features or improve performance.
• Portability: Many software applications can run on various devices and platforms, such as Windows, macOS, and mobile devices.
• Scalability: Software can handle an increasing amount of work or data and make it suitable for businesses or personal use.
• Automation: Software can automate routine tasks, saving time and reducing human error.

Examples of Software

• Web Browsers: Google Chrome, Mozilla Firefox, Safari
• Messaging Apps: WhatsApp, Facebook Messenger, Telegram
• Productivity Tools: Microsoft Office Suite (Word, Excel), Google Docs, Slack
• Media Players: VLC, Spotify, YouTube
• Video Games: Fortnite, Candy Crush, Minecraft

What Is Firmware?

Firmware is a set of instructions stored in a device’s non-volatile memory. This memory keeps data safe even when the device is turned off or loses power. It works differently from regular RAM, which only holds information while the device is powered on.

Firmware is specialized software permanently programmed into a device’s hardware to control its essential functions. It acts as a middleman between the device’s hardware and higher-level software.

Think of firmware like a car engine: you can’t see it while you’re driving, and you don’t directly interact with it, but it’s essential for everything to work properly.

Similarly, firmware is not something you “use” directly, but it’s important to the operation of nearly every device. While firmware is called “firm,” it can be updated to fix problems or add new features, just like upgrading a car engine.

Firmware Key Features

• Low-Level Control: Firmware works at a low level by directly managing hardware functions.
• Stability: It is usually simple and stable and instructs a device’s operation without frequent changes.
• Embedded Nature: Firmware is embedded within a device and is not meant to be regularly changed by the user.
• Essential for Boot-Up: Firmware is responsible for starting devices, performing diagnostics, and initializing hardware components.
• Occasional Updates: Firmware updates are rare but important. They typically address hardware performance, security, or functionality.

Examples of Firmware

Here are some examples of firmware from our daily lives:

• Smartphone Firmware: The software that controls your phone’s camera, touch screen, or GPS functionality.
• Wi-Fi Router Firmware: The built-in code that manages your internet connection and network security settings.
• TV Remote Control: Firmware controls how the buttons on your remote communicate with your TV.
• Car Electronics: A car’s engine control unit (ECU) firmware governs the engine’s performance, fuel efficiency, and safety features.
• Printers: Firmware directs how a printer handles printing tasks and connects to a computer or network.

Key Differences Between Firmware and Software

Firmware and software both serve important roles in making devices function; they do so differently. Firmware provides the foundational instructions that make hardware work, while software adds features and capabilities that allow you to interact with devices and perform various tasks.

Understanding the following differences can help you make better decisions about troubleshooting, upgrading, or using technology in your daily life.

Purpose

Firmware is responsible for running the core functions of a device’s hardware. It acts as a bridge between the hardware and other software. It ensures everything runs smoothly at the most basic level. For example, firmware in a smartphone controls functions like the camera, touchscreen, and system boot-up.

Software is designed to provide additional features or allow you to interact with the device in various ways. It includes everything from web browsers to video games, making devices usable for specific tasks or entertainment.

Location

Firmware is stored directly on the hardware, often in specialized memory chips like ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), or flash memory. This ensures it remains functional even when the device is powered off or disconnected.

Software is typically stored on devices like hard or solid-state drives (SSDs) for computers or on cloud storage for web-based applications. Unlike firmware, software can be moved between devices and stored on external media.

Update Frequency

Firmware is updated less often and usually requires a technical process to update, often provided by the device manufacturer. The updates are typically meant to fix issues or improve the hardware’s performance, but they don’t happen frequently.

Software, in contrast, is updated much more regularly. Software updates are common and typically occur via simple downloads. These updates can add new features, improve security, or fix bugs, and the process is often user-friendly.

Level of Complexity

Firmware operates at a low level, controlling basic hardware functions. It provides simple instructions for the device’s operation, such as controlling the boot-up sequence or managing hardware interfaces.

Software is much more complex and operates at a higher level. It performs various tasks, from word processing to gaming, and often provides a rich interface. The software requires complex programming to handle multiple functionalities.

Interaction with Users

Firmware typically operates in the background with minimal user interaction. It’s designed to ensure the device’s core functions are working, but it doesn’t directly interact with users. Think of the firmware in your microwave – it controls the buttons and cooking process but isn’t something you directly interact with in a meaningful way.

Software, on the other hand, is something you interact with every day. Whether you’re typing a document in Microsoft Word, browsing the internet in Chrome, or editing photos in Photoshop, you’re using software that provides a user interface for easy interaction.

Dependency

Firmware is closely linked with specific hardware. It is essential for the hardware to function and is designed specifically for the device it’s embedded in, like a printer or a router. Without the correct firmware, the hardware wouldn’t be able to operate properly.

Software can be used across different types of hardware. It’s not tied to a specific device in the same way firmware is. For example, software like Google Chrome or Microsoft Word can run on different computers or mobile phones, depending on the platform it supports.

Examples to Differentiate Firmware and Software

Here are five examples to help you understand how firmware and software differ in everyday devices:

Example 1: Smartphone

• Firmware: The firmware in a smartphone is responsible for managing essential hardware functions like the camera, touchscreen input, and how the device starts up. It’s built into the phone and runs even when you’re not using any apps. When you turn your phone on, the firmware ensures that the system can interact with the phone’s components, like the camera and display.
• Software: Software on your smartphone includes mobile apps for messaging like WhatsApp or games like Candy Crush. These apps are what you interact with directly. They use the phone’s hardware but are separate from the firmware and allow you to perform tasks like chatting, playing games, or browsing the web.

Example 2: Smart TV

• Firmware: The firmware in a smart TV controls basic functions such as turning the TV on, adjusting the volume, and connecting to Wi-Fi. It also enables the TV’s ability to receive signals from the remote control. Without firmware, the smart TV couldn’t interact with its hardware components, such as the screen or speakers.
• Software: The software in a smart TV includes streaming apps like Netflix, YouTube, or Amazon Prime Video. These apps let you choose and watch content. While the firmware ensures the TV works properly, the software makes the TV interactive and enjoyable by providing features like streaming services and on-screen menus.

Example 3: Printer

• Firmware: A printer’s firmware manages its internal functions, such as receiving data from a computer and controlling the printer’s hardware (like the print head and paper feed). It ensures that the printer can print documents accurately without the user having to adjust internal settings manually.
• Software: The software related to the printer could be the printer’s driver, which you install on your computer. This driver allows your computer to communicate with the printer. The software also includes programs like Microsoft Word or Adobe Acrobat, which allow you to create and print documents. The printer’s firmware works in the background, while the software provides the tools you use to send data to the printer.

Example 4: Router

• Firmware: A router’s firmware controls its basic networking functions, such as managing how your internet connection is received and distributed to various devices. It also governs security features like firewalls and wireless settings. Firmware is essential for the router to operate and ensure a stable connection.
• Software: The software here could include the app or program you use to set up or manage your router’s settings. For example, apps that let you monitor your network or change your Wi-Fi password are software tools. These applications help you customize the way the router interacts with your devices but depend on the firmware for the actual network operations.

Example 5: Microwave

• Firmware: The firmware in a microwave controls its core operations, such as how the microwave heats food, manages cooking times, and responds to button presses. It helps the microwave understand commands from the user, like “start” or “stop,” and ensures the microwave runs safely.
• Software: The software in most microwaves is minimal, but some newer models may offer features like pre-programmed cooking instructions or smart settings that allow you to set the microwave using a smartphone app. The app is software that interacts with the microwave, but the firmware controls the actual cooking process.

Conclusion

Firmware is the basic, low-level code that controls hardware and ensures it operates correctly. It is tightly tied to the device’s hardware and works in the background, often with little direct user interaction.

On the other hand, software is more versatile and user-facing, offering features and functions that allow you to interact with devices. Understanding these two is important to solving problems and making your devices work better.
