Study Notes
Computer Fundamentals
- A computer is a tool for processing data to produce information, taking input, storing it, processing it in the CPU, and then outputting the result.
- Data refers to raw facts (name, age, etc.), while information is processed data (e.g., salary, exam results).
- Data processing methods include manual (using tools like pens, chalk), mechanical (typewriters, adding machines), and computer methods.
- Manual methods are slow, prone to human error, and unsuitable for large datasets.
- Mechanical methods are faster than manual, somewhat less prone to error, but still limited in volume and speed.
- Computer methods are fast, accurate, handle large volumes, are reliable, and flexible (capable of various tasks).
- Key computer characteristics include speed, accuracy, storage capacity, and automation.
- Computers have input (keyboard, mouse), processing (CPU), and output (screen, printer) units.
- Main memory (RAM) stores temporary data; secondary memory (hard disk) stores permanent data.
- Software provides instructions for a computer to execute tasks; includes system software (operating systems) and application software (programs).
- Computer users range from experts to novices. Environments affect computer operations (e.g., electricity).
Computer System Components
- Computer systems consist of hardware (physical components) and software (instructions).
- Hardware includes the input unit (keyboard, mouse), processing unit (CPU), and output unit (monitor, printer).
- Secondary storage devices (hard drives, flash drives) store data.
- Software consists of operating systems and applications.
- Input devices receive data: keyboard, mouse, scanner.
- Output devices show results: monitor, printer.
- The CPU handles data processing and instructions.
