How Does a Computer Process Data? - Lesson 2 3 Computer System Components A computer system requires many components  to do its job: It requires some device or method to input data so it  can be processed. It requires circuits and programs in order to process  the data. It needs some type of output device to give the result  of its processing to the user. It needs some mechanism for storing data.

How Does a Computer Process Data? - Lesson 2 5 System Motherboard Inside the case of a modern PC is the  motherboard, which contains the electronic  circuitry of the computer. Components found on the motherboard include The primary processing chip (CPU). The memory chips. Expansion slots for system interface cards. Ports for connecting external devices. BIOS chips that control system start-up. The circuitry that enables all of these components to  communicate.

How Does a Computer Process Data? - Lesson 2 7 The Central Processing Unit The CPU is the brains of a computer system. The CPU is housed on a silicon chip that contains  millions of switches and circuits. The CPU has two primary sections: The Arithmetic/Logic Unit (ALU) This section performs arithmetic and logical operations. The Control Unit
