    Study Notes

    Computer Definition and Function

    • A computer is an electronic device that takes input, processes it, and produces output.
    • Computers operate under the control of instructions stored in their memory.
    • They accept and manipulate data according to specified rules, produce output, and store results for future use.

    Data and Information

    • Data is raw, unprocessed facts, figures, and symbols.
    • Information is organized, meaningful, and useful data.
    • Computers use hardware and software to process data into information.

    Hardware and Software

    • Hardware refers to the physical components of a computer system (e.g., electronic, mechanical).
    • Software consists of instructions that tell the hardware how to perform tasks.

    Components of a Computer

    • A computer system is primarily divided into three components: input devices, CPU (Central Processing Unit), and output devices.
    • Input devices allow users to enter data and instructions into the computer.
    • The CPU is responsible for processing the data.
    • Output devices present processed data in a user-friendly format.

    Input and Output

    • Input refers to data or instructions entered into the computer, including audio, video, graphics, programs, commands, and user responses.
    • Output is the processed data presented in a useful form, including text, audio, video, graphics, and animations.
    • Output can be categorized as soft copy (displayed on screen) or hard copy (printed on paper).

    Information Processing Cycle

    • The information processing cycle involves the sequence of input, processing, output, and storage.
    • Data is inputted, processed by the CPU, converted into information, and outputted.
    • The computer stores data, information, and instructions for future use.

    Data and Information in Detail

    • Data includes raw facts, figures, events, and transactions.
    • Information is derived from processed data, making it meaningful and useful.
    • Example: Admission forms provide data. This data is processed to create a merit list, which represents information about eligible students.
