Embedded Systems differ from general-purpose computers in that they are designed for specific tasks and applications, often with real-time constraints. While general-purpose computers can run a variety of software, embedded systems are optimized for particular functions, like controlling appliances or managing hardware. They typically have limited hardware resources, such as processing power and memory, and may run on dedicated operating systems. This makes embedded systems more efficient and reliable for their intended purposes, seen in devices like washing machines or automotive controls.
