A computer system is to work more efficiently than humans a combination of hardware and software that work together to process data programs or applications that run The physical items that make up the compuer Hardware is to work more efficiently than humans a combination of hardware and software that work together to process data programs or applications that run The physical items that make up the compuer Software is to work more efficiently than humans a combination of hardware and software that work together to process data programs or applications that a computer system runs The physical items that make up the compuer Match the correct item to their group Software Word processor Email Client Internet browser Hardware CPU RAM Printer Embedded systems are computers built into other devices, like dishwashers, microwaves and TV's. They are usually dedicated systems. In a dishwasher the system could control the water pumps and water release mechanisms.Because they are dedicated to a single task, they are normally easier to design, cheaper to produce and more efficient than a general purpose system From the options below highlight those which can be found in the CPU The control unit The arithmetic logic unit Cache The CPU is the brains of the computer. It processes all of the data and instructions to make it work. The processing power can depend on a number of factors such : clock speed, number of cache the size of cache. Computer systems will tend to always have an input and output.
