EMBEDDED SYSTEMS

Definition : 

Definition It is a combination of software and hardware designed to perform specific task It is a system which is hidden inside Everything other than PC is an embedded system It works under certain time constraint

Characteristics : 

Characteristics Works in a time constraint environment Good performance and high reliability Less cost requirement due to mass production Designed for specific task

Why embedded systems???? : 

Why embedded systems???? Very rapid growing field Various effect on our daily lives We use them everyday
