the cell phones in your pocket. Even things like your car‚ dishwasher‚ dvd player‚ and even TVs include some form of computers. All this would not be possible without the invention of the integrated circuit or IC. This led to the creation of the Microprocessor or CPU (central processing unit) which acts as the brain of the computer. To better help illustrate the function and need for a CPU you must go back to the first all electric computers. Now computers have a long history but modern electronic

Computer is a processing machine which processes raw data to produce meaningful data. It has tremendous change with comparison to calculator. Characteristics of Computers: - Computers have got their importance due to the following characteristics: - 1. Accuracy: - Computer performs every operation with equal and high accuracy. Errors can occur in a computer due to only human mistakes‚ weaknesses and imprecise thinking. 2. Repeatitiveness: - Once the set of instructions are permanently

Premium Central processing unit Computer Microprocessor
A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The
