4 Parts
It has 2 parts: Hardware and Software. It has 3 parts: Hardware, Firmware and Software.
5.Tasks
It can perform many tasks. It performs limited tasks.
6.Cost to user
The user has to pay more for a computer. The user incurs lesser cost for an embedded system.
7.Peripherals
Computers have peripherals such as keyboard and mouse, display, printer, Hard disk drives, floppy disk drives, optical disc drives etc. Embedded Devices have peripherals such as Serial Communication Interfaces (SCI), Synchronous Serial Communication Interface, Universal Serial Bus (USB), Multi Media Cards (SD cards, Compact Flash) etc.
