  13. What are the two main types of RAM?

    SRAM (Static RAM) and DRAM (Dynamic RAM).

  14. What is cache memory and why is it used?

    A small, very fast memory between the CPU and RAM that stores frequently used data to speed up processing.

  15. Order these storage units from smallest to largest: GB, KB, TB, MB, Byte.

  16. How many bits are in one byte, and how many bytes in one kilobyte?

    1 byte = 8 bits; 1 KB = 1024 bytes.

  17. What is the difference between primary memory and secondary memory?

    Primary memory (RAM/ROM) is directly accessible by the CPU and mostly volatile; secondary memory (HDD, SSD, CD) is non-volatile permanent storage not directly accessed by the CPU.

  18. What is the base (radix) of the binary, octal, decimal, and hexadecimal number systems?

    Binary = 2, Octal = 8, Decimal = 10, Hexadecimal = 16.

  19. What is the decimal equivalent of the binary number 1010?

    10.

  20. What digits/symbols are used in the hexadecimal number system?

    0-9 and A, B, C, D, E, F (where A=10 to F=15).

  1. What is ASCII and what is it used for?

    American Standard Code for Information Interchange; a coding scheme that represents characters as numbers (standard ASCII uses 7 bits).

  2. What is the function of an operating system?

    It manages hardware and software resources, controls memory, processes, files, and I/O, and provides an interface between the user and the computer.

  3. Give two examples each of a GUI-based and a command-line operating system.

    GUI: Windows, macOS. Command-line: MS-DOS, UNIX/Linux (shell).

  4. What is multitasking in an operating system?

    The ability of an OS to run multiple tasks or programs at the same time.

  5. In an OS, what is booting and what are its two types?

    Booting is starting up a computer; types are cold booting (from power off) and warm booting (restart while powered on).

  6. What keyboard shortcut saves a document, and which copies and pastes in MS Word?

    Save = Ctrl+S; Copy = Ctrl+C; Paste = Ctrl+V.

  7. What is the default file extension of MS Word documents (2007 and later)?

    .docx (older versions used .doc).

  8. In MS Excel, what is a cell, and how is its address written?

    A cell is the intersection of a row and a column; its address is the column letter followed by the row number, e.g., A1.

  9. In MS Excel, what symbol must every formula begin with?

    The equals sign (=).

  10. Write the Excel formula to add the values in cells A1 through A10.
