General Purpose Computer	Embedded Systems
It is designed using a microprocessor as the main processing unit.	It is mostly designed using a microcontroller as the main processing unit.
It contains a large memory semiconductor memories like cache and RAM. it also contains secondary storage like hard disks etc.	It uses semiconductor memories,but does not require secondary memories like hard disk,CD.lt sometime has special memory called flash memory.
It is designed such that it can cater to multiple tasks as per requirement.	It is designed such that it can cater to a particular predefined task.
It is mostly costlier compared to the embedded systems	It is cheaper compared to a computer.
It requires huge number of peripheral devices and their controllers	It is cheaper as it requires less no of peripheral devices and their controllers are microcontroller chip itself.
The Operating system and other software for the general purpose computers, are normally complicated and occupy more memory space	The operating system(mostly RTOS i.e Real Time Operating System) and other software occupy less memory space.
