What is an Embedded system?
Summary
TLDRThis video offers an insightful exploration of embedded systems, defining them as special-purpose computers designed for specific tasks. It contrasts these with general-purpose computers like laptops and smartphones, highlighting the cost-effectiveness and efficiency of embedded systems for targeted functions. The video categorizes embedded systems into three types: subsystems, which are part of larger systems like car dashboards; standalone systems, which operate independently like USB drives; and networked systems, exemplified by home automation and the Internet of Things (IoT). The host invites viewers to learn more on their website and engage with the content.
Takeaways
- 💡 Embedded systems are special-purpose computers designed for specific tasks.
- 📱 General-purpose computers like laptops and smartphones serve multiple purposes, unlike embedded systems.
- 🔢 A calculator is a simple example of an embedded system, as it's designed for one specific function.
- 💻 Special-purpose computers are often more cost-effective and efficient for tasks that don't require the capabilities of general-purpose computers.
- 🚗 Embedded subsystems are components of larger systems, like a car's digital dashboard.
- 🎵 Standalone embedded systems can operate independently, such as USB drives and digital cameras.
- 🏡 Networked embedded systems work together to perform complex tasks, like home automation systems.
- 🌐 The Internet of Things (IoT) is a global network of interconnected embedded systems.
- 🌟 Embedded systems can be classified into three categories: subsystems, standalone systems, and networked systems.

Q & A
What is an embedded system?
-An embedded system is a special-purpose computer, custom-built to serve a specific purpose, as opposed to a general-purpose computer that can perform multiple functions.
Why are embedded systems considered special-purpose computers?
-Embedded systems are considered special-purpose computers because they are designed to perform a specific function or a set of functions, unlike general-purpose computers which are versatile and can handle a wide range of tasks.
What is the difference between general-purpose and special-purpose computers?
-General-purpose computers like desktops, laptops, and smartphones are versatile and can perform multiple tasks, while special-purpose computers are designed for a single or limited set of functions, such as a calculator for calculations.
Why are embedded systems like calculators still relevant when we have computers?
-Embedded systems like calculators are relevant because they are specifically designed for a single task, are often more cost-effective, and can be more efficient for that task compared to using a general-purpose computer.
What are the three broad categories of embedded systems?
-The three broad categories of embedded systems are subsystems, standalone systems, and networked systems.
Can you give an example of an embedded subsystem?
-An example of an embedded subsystem is a digital dashboard in a car, which is a part of the larger system of the car itself.
What is a standalone embedded system and provide an example?
-A standalone embedded system is a device that can perform its function independently, such as a USB drive for storing data or a digital camera for taking pictures.
How does a networked embedded system function?
-A networked embedded system functions by connecting multiple devices or sensors, often through a network, to perform a collective task, like home automation systems.
What is the Internet of Things (IoT) in relation to embedded systems?
-The Internet of Things (IoT) is a special subclass of networked embedded systems where the network spans globally, connecting devices and allowing them to exchange data over the internet.
Why might general-purpose computers be considered overkill for certain tasks?
-General-purpose computers might be overkill for certain tasks because they offer more capabilities than needed for specific functions, and specialized embedded systems can perform those tasks more efficiently and cost-effectively.
What are some advantages of using embedded systems over general-purpose computers for specific tasks?
-Some advantages of using embedded systems include their cost-effectiveness, efficiency in performing specific tasks, and often smaller size and lower power consumption compared to general-purpose computers.
