2.The CPU is regarded as the computer's brain. The CPU is responsible for all data processing operations. It saves information such as data, intermediate results, and instructions (program). It directs the operation of all computer components.
3.Main memory holds instructions and data when a program is executing, while auxiliary memory holds data and programs not currently in use and provides long-term storage.
4.A storage device is any type of computing hardware that is used for storing, porting or extracting data files and objects. Storage devices can hold and store information both temporarily and permanently. They may be internal or external to a computer, server or computing device.
5.A disk drive is a technology that enables the reading, writing, deleting and modifying of data on a computer storage disk.
6.Peripherals may be located inside or outside a computer's case (called an internal or external device, respectively). The I/O bus is the collection of circuits where an internal device is attached. An I/O port (such as parallel or serial port) is a connector where an external device is connected (plugged in).
