Computer architecture basically includes rules which describe the implementation and organization of computer systems. Computer is a device which is used to store and process any data. The computer processor architecture gives an idea about the software used and hardware connected. It is the most complex to learn and analyse too. Studying more about different types of computer architecture and its concepts help to achieve more data processing and receptivity. Computer science is predominantly the study of the vast arena of computer and its technology. The Power PC made by Apple, Motorola and IBM is one example of computer architecture with enhanced performance. Nowadays technology has been developed so efficiently that even machines began to behave like human beings. Besides being an electronic machine, computer has the capability to perform arithmetic and logical functions. Technology is getting advanced day to day to extend its capability in performance.
