What is an embedded system, and how does it differ from a general-purpose computer?

Explanation:

An embedded system is a specialized computing system that performs dedicated functions or tasks as part of a larger system. Unlike general-purpose computers, which are designed to perform a wide range of tasks, embedded systems are optimized for specific applications. They are often resource-constrained, with limited processing power, memory, and storage, and are designed for real-time performance and reliability.

Key Talking Points:

• Embedded systems are designed for specific tasks.
• They are part of a larger system or device.
• They usually have resource constraints.
• Embedded systems prioritize real-time performance and reliability.
• General-purpose computers are versatile and designed for multiple tasks.
