Cheat Sheet
- Core Stages of the Information Processing Cycle (IPOS) -
The cycle comprises four sequential steps - Input, Processing, Storage, and Output - often memorized with the acronym IPOS (University of Cambridge Computer Science Dept.). A handy mnemonic is "I Prefer Our Systems" to reinforce the order. Recognizing this framework helps you map any computing task to its lifecycle.
- Input Stage & Data Acquisition -
This stage converts real-world signals into digital form via devices like keyboards, mice, scanners, or analog-to-digital converters (ADC) in sensors (MIT OpenCourseWare). For example, an image scanner samples light intensity and encodes it into pixel data. Understanding sampling rate and resolution is key for accurate data capture.
- Processing Mechanics: Fetch-Decode-Execute -
The CPU's Control Unit (CU) and Arithmetic Logic Unit (ALU) perform the fetch-decode-execute cycle - fetch an instruction, decode its purpose, then execute it (IEEE Computer Society). A fun memory aid is "Every Dog Fetches Delicious Bones." Grasping how registers and the program counter work demystifies how calculations and logic operations occur.
- Storage Hierarchy: Primary vs. Secondary -
Primary memory (RAM) is volatile and ultra-fast (access times ~10 - 50 ns), while secondary storage (HDDs, SSDs) offers non-volatile, high-capacity retention (NIST Digital Storage Report). Remember: "RAM runs fast, Disk digs deep." Balancing speed, cost, and capacity is crucial in system design.
- Output & Feedback Controls -
Output devices such as monitors, printers, and speakers translate processed data into human-readable form, with metrics like DPI for print and refresh rate for displays (ACM Computing Surveys). In interactive systems, feedback loops - like a thermostat adjusting temperature - close the cycle by using output data to inform new inputs. Recognizing feedback's role solidifies your grasp of dynamic, real-time data processing.
