IRDAI Assistant Manager Computer Knowledge flashcards — 63 questions with answers

  1. What distinguished first-generation computers (1940s-1950s) in terms of their core electronic component?

    They used vacuum tubes for circuitry and magnetic drums for memory; they were large, consumed huge power, and generated a lot of heat.

  2. Which electronic component defined second-generation computers, and what was its advantage over the first generation?

    Transistors, which were smaller, faster, cheaper, more reliable, and consumed less power than vacuum tubes.

  3. What technology characterized third-generation computers?

    Integrated Circuits (ICs), which placed many transistors on a single silicon chip, increasing speed and efficiency.

  4. What component defines fourth-generation computers?

    The microprocessor (VLSI - Very Large Scale Integration), placing thousands of integrated circuits on a single chip.

  5. What is the defining concept of fifth-generation computers?

    Artificial Intelligence (AI), based on parallel processing, ULSI technology, and the goal of human-like reasoning and natural language.

  6. Classify computers by size from largest to smallest.

    Supercomputer, Mainframe, Minicomputer, Microcomputer (personal computer).

  7. What are the three types of computers based on data handling, and how do they differ?

    Analog (continuous data), Digital (discrete data/binary), and Hybrid (combines both analog and digital).

  8. Define computer hardware and give examples.

    Hardware is the physical, tangible components of a computer, such as the CPU, monitor, keyboard, mouse, RAM, and hard drive.

  9. Define computer software and name its two main types.

    Software is the set of programs/instructions that tell hardware what to do. The two types are system software (e.g., OS) and application software (e.g., Word).

  10. List the memory hierarchy from fastest/smallest to slowest/largest.

    Registers, Cache memory, Main memory (RAM), Secondary storage (HDD/SSD), Tertiary/offline storage (tape, optical).

  11. What is the difference between RAM and ROM?

    RAM is volatile read/write memory used for temporary working data; ROM is non-volatile read-only memory that stores permanent instructions like the BIOS.

  12. What is the difference between SRAM and DRAM?

    SRAM (Static RAM) uses flip-flops, is faster and used for cache; DRAM (Dynamic RAM) uses capacitors that need refreshing, is slower/cheaper, and used as main memory.

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

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

  14. Name the three main components of a CPU.

  19. What is the key difference between an HDD and an SSD?

    An HDD uses spinning magnetic platters (mechanical); an SSD uses flash memory with no moving parts, making it faster and more durable.

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

    Byte, KB (kilobyte), MB (megabyte), GB (gigabyte), TB (terabyte).

  7. Name four examples of operating systems.

    Windows, macOS, Linux, Unix, and Android.

  8. What is the difference between a batch OS and a real-time OS (RTOS)?

    A batch OS executes grouped jobs without user interaction; an RTOS processes data within strict time constraints for time-critical tasks.

  9. What is a multitasking operating system?

    An OS that allows multiple tasks/processes to run seemingly simultaneously by rapidly switching the CPU between them.

  10. What is the difference between a GUI and a CLI operating system interface?

    GUI (Graphical User Interface) uses icons, windows, and a mouse; CLI (Command Line Interface) requires typing text commands.

  11. Which MS Office application is used for word processing, and name its default file extension.

    MS Word; default extension is .docx (older .doc).

  12. Which MS Office application is a spreadsheet, and what is its file extension?

    MS Excel; extension is .xlsx (older .xls).

  13. In MS Excel, what is the difference between a relative and an absolute cell reference?
