Embedded Systems

Purpose and Characteristics of Embedded Systems

• An embedded system is a computer system built into a larger device to control specific functions.
• It consists of both hardware and software, which is often called firmware.
• Embedded systems are designed for specific tasks, unlike general-purpose computers.
• They usually don't have a full operating system and instead use simple control software.
• Embedded systems are optimized for reliability, efficiency, and low power consumption.

Examples of Embedded Systems

• Dishwasher – controls wash cycles and temperature.
• Microwave – manages cooking time and power levels.
• Fridge – regulates temperature and cooling systems.
• Smartphone – contains several embedded systems like GPS, camera, and sensors.
• Television – controls picture processing and display functions.
