Flashcards

What is a computer?

A tool or machine that processes data to provide information. It takes input data, stores it, processes it, and outputs the results.

What is data?

Facts or information about a person, object, or place. Examples include name, age, or height.

What is information?

Processed data that has meaning and provides insights. Examples include a student's exam results or a list of successful job candidates.

What is the Manual Method of data processing?

Using tools like chalk, pen, or pencil to manually record, classify, and process data. It is slow, prone to errors, and not suitable for large data volumes.

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.
