Processing cycle

The Processing cycle is the change processing of information in any manner detectable by an observer.

Input

Input is the collection of raw data and putting it into an information processing system or computer. Input devices can be hardware devices, software, or user driven.

For example the types of inputs are the keyboard ,mouse ,scanner ,barcode reader, joystick ,and the digital data table microphone.

​

​

Outputs

Output is the presentation of any data exiting a computer system. Types of output include visual, printed, or audio.

​

The types of outputs are the monitor printer projector speakers

Processing

The system unit is the core of a computer system and the main processing center. Usually it's a rectangular box that holds many electronic components that process information. The most important part of these components is the central processing unit (CPU) also called the processor. The CPU is the brain of your computer it is the key component in interpreting computer program instructions and processes data. The next most critical element of a processing is RAM, often referred to as "primary storage" or "main memory". Random Access Memory (RAM) temporarily stores information that the CPU uses while the computer is on and is erased when the computer is turned off.

​

What processors do is calculate, interpret, and change data.

Storage

Computers usually have one or more disk drives, commonly referred to as a hard drive—devices that store information. The disk preserves the information even when your computer is turned off. All computers have a hard disk drive that can hold massive amounts of information; they usually serve as your computer's primary means of storage, holding almost all of your programs and files. The hard disk drive is normally located inside the system unit.

​

Where the file is stored is in the Ram and HARD DISK.
