    • Data, Information, and Knowledge:

      • Data are raw alphanumeric values from various sources.
      • Information is processed data, organized to provide context and meaning.
      • Knowledge is the understanding derived from information.

    • Data Processing Cycle:

      • Data is collected from various sources.
      • Data is processed to convert raw data into understandable information.
      • Processed information is stored for future use.
      • Output is the final result after processing and storage.

    • Functionality of Computers:

      • Input Devices: Keyboard, mouse, scanner, etc.
      • Output Devices: Monitor, printer, speakers, etc.
      • Central Processing Unit (CPU): Includes the Arithmetic Logic Unit (ALU) and Control Unit (CU) which process data.
      • Memory Unit: Contains Random Access Memory (RAM) and Read-Only Memory (ROM) and Cache.
      • Storage: Hard drives, USB flash memory, etc.
      • Computers use these components to take input, process it, store the results, and provide output.

    • Evolution of Storage Media:

      • Storage media has evolved from 8-inch floppy disks to CDs, DVDs, USBs, external hard drives, and cloud storage.
      • Each advancement offers greater storage capacity and convenience.

    • Personal Computer Characteristics (Hardware):

      • Hard Disk: A secondary storage device, where operating systems, applications, and files are stored.
      • CPU: The processor that processes instructions.
      • RAM: Primary memory that stores data being used by the CPU.

    • Software:

      • System Software: Manages hardware and resources (e.g., operating systems like Windows, MacOS, Linux).
      • Application Software: Programs designed for specific tasks (e.g., word processors, web browsers, games).
        • Web Browsers: Software used to access webpages. Example browsers are Edge, Chrome, and Safari.
        • Office Applications: Software used for tasks such as word processing, spreadsheets, presentations, and databases. Example packages are Microsoft Office and Google Suite.
        • Meta Applications: Social media platforms used for communication and sharing.

    • Types of Memory:

      • Primary Memory (RAM): Volatile memory used for temporary storage. Crucial for speed.
      • Secondary Memory: Non-volatile memory for long-term storage (Hard disks, etc.) Provides capacity.

    • RAM and CPU:

      • RAM: (Random Access Memory) is a kind of main memory used by the CPU to store data.
      • CPU: (Central Processing Unit) is where the processing of instructions takes place, critical in any computing device.
