Study Notes
Input Process Output Storage System
- The Input Process Output Storage (IPOS) cycle is a set of instructions that computers follow to process information.
- The IPOS cycle consists of three stages: Input, Process, and Output.
- Input devices are used to enter data into the computer, such as keyboards, mice, and scanners.
- Process devices, also known as the CPU (Central Processing Unit), are the brain of the computer and control its actions.
- Output devices display or present the processed information, such as monitors, printers, and speakers.
Input Devices
- An input is the data that goes into the computer.
- Examples of input devices include:
- Keyboard
- Mouse
- Joystick
- Scanner
- Microphone
- Webcam
- Touchpad
- Light pen
- Touch screen
- Specialised input devices include:
- Direct Data Entry (DDE) devices, such as MICR (Magnetic Ink Character Recognition), OCR (Optical Character Recognition), OMR (Optical Mark Recognition), and EFTPOS (Electronic Fund Transfer at Point of Sale)
- RFID (Radio Frequency Identification) devices
Processing Device
- The CPU (Central Processing Unit) is the brain of the computer and controls its actions.
- The CPU processes data and performs calculations.
- Examples of processors include Intel and AMD.
Output Devices
- An output is the processed information that is presented to the user.
- Examples of output devices include:
- Monitor
- Printer
- Speaker
- Projector
- Plotter
- Output devices display or present the processed information.
Storage Devices
- Storage devices are used to save data.
- Examples of storage devices include:
- Hard drive
- Memory stick
- Flash memory
- Memory card
- Optical storage devices (CD-ROM, DVD-R, DVD-RW, Blu-ray)
- Solid state drives (SSD)
- Magnetic storage devices use magnets to store data.
- Solid state storage devices use flash memory to store data.
IPOS Cycle
- The IPOS cycle is used in everyday devices, such as microwaves and washing machines.
- The IPOS cycle is used to process instructions and provide feedback.
- The IPOS cycle is used in computers to process information and provide output.
This quiz covers the stages of the Input Process Output Storage cycle, hardware devices used at each stage, and applying the IPOS cycle to real-life problem-solving scenarios.
