Processing Device
The Central Processing Unit (CPU) is the hardware processing
device that works on input data and sends the result to the output
devices. The CPU is a chip which is placed inside the CPU box.
CPU is also called the brain of a computer as it is responsible for
all the work done. A CPU is further divided into three parts: ALU, CPU CPU box
CU and MU. CPU
Arithmetic Logic Unit (ALU) Control Unit
ALU does all the arithmetic calculations like addition, subtraction,
multiplication, division, etc. It also does comparisons like greater Arithmetic Logic Unit
than, less than, equal to, etc.
Control Unit (CU) Memory Unit
CU coordinates and controls all the parts of the CPU. The CU gets the data and instructions
from the memory unit and passes them to the ALU in a step by step manner.
Memory Unit (MU)
The CPU also has a memory like human beings. The MU stores the data and instructions that you
give to the computer along with the results of the processing. Memory Unit is known by different
names like Internal storage unit, main memory or primary storage or RAM.
Output Devices
The result we get after processing is called output. The devices which help us get these results
or outputs are called output devices.
Now let us learn about more output devices.
Printer
A printer produces a hard copy (printouts) from a computer usually onto
a paper.
Speakers
Speakers are used to listen to music, voice and sound on a computer.
