Foreign Service Officer Test (FSOT) Computers, Mathematics, and Science and Technology flashcards — 58 questions with answers

  1. What are the four basic components of a computer's hardware architecture?

    Input devices, the CPU (processor), memory/storage, and output devices.

  2. What is the difference between RAM and ROM?

    RAM (Random Access Memory) is volatile working memory that loses its contents when power is off; ROM (Read-Only Memory) is non-volatile and retains permanently stored instructions (e.g., firmware/BIOS).

  3. What is the difference between hardware and software?

    Hardware is the physical, tangible components of a computer; software is the set of programs and instructions that tell the hardware what to do.

    System software that manages hardware resources and provides services for application programs. Examples: Windows, macOS, Linux.

  5. How many bits are in a byte, and what is a byte typically used to represent?

    8 bits make 1 byte, which typically represents a single character of text.

  6. What is the binary number system and what two digits does it use?

    The base-2 number system used by computers, using only the digits 0 and 1.

    A whole number greater than 1 divisible only by 1 and itself. The first five are 2, 3, 5, 7, and 11.

  3. How do you convert a fraction to a percentage?

    Divide the numerator by the denominator and multiply the result by 100.

  4. What is the difference between a rational and an irrational number?

    A rational number can be expressed as a ratio of two integers (a fraction); an irrational number cannot (e.g., pi or the square root of 2).

  5. What is the greatest common factor (GCF) of two numbers?

    The largest positive integer that divides both numbers without a remainder.

  6. What is the quadratic formula?

    x = [-b plus or minus the square root of (b squared minus 4ac)] divided by 2a, used to solve ax squared + bx + c = 0.

  7. What does it mean to solve a linear equation, and what form is standard slope-intercept?

    To find the value(s) of the variable that make the equation true. Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

  8. In the slope formula, how is slope between two points calculated?

    Slope = (y2 - y1) / (x2 - x1), the change in y divided by the change in x (rise over run).

  9. What is the rule for multiplying exponents with the same base?

    Add the exponents: x^a times x^b = x^(a+b).

  10. How do you factor the difference of two squares?

    a squared minus b squared factors into (a + b)(a - b).

  11. What is the formula for the area of a triangle?

    Area = 1/2 times base times height.

  12. What is the Pythagorean theorem?

    In a right triangle, a squared plus b squared equals c squared, where c is the hypotenuse.

  13. What is the formula for the circumference of a circle?

    Circumference = 2 times pi times the radius (or pi times the diameter).

  14. What is the area of a circle?

    Area = pi times the radius squared.

  15. How many degrees are in the interior angles of a triangle, and of a quadrilateral?

    A triangle's interior angles sum to 180 degrees; a quadrilateral's sum to 360 degrees.

  16. What is the formula for the volume of a rectangular box (rectangular prism)?

    Volume = length times width times height.

  17. How do you calculate distance given rate and time?

    Distance = rate times time (d = rt).

  18. How do you calculate simple interest?

    Interest = Principal times Rate times Time (I = PRT).

  19. If a shirt costs $40 and is discounted 25%, what is the sale price?

    $30 (25% of $40 is $10, so $40 minus $10 equals $30).

    Force equals mass times acceleration (F = ma).

  21. What is the difference between an element and a compound?

    An element is a pure substance made of one type of atom; a compound is a substance made of two or more different elements chemically bonded together.

  22. What are the three states of matter and what distinguishes them?

    Solid (fixed shape and volume), liquid (fixed volume, takes container's shape), and gas (no fixed shape or volume); they differ in particle arrangement and energy.

  23. What is the difference between a physical and a chemical change?

    A physical change alters form or appearance without changing chemical composition (e.g., melting ice); a chemical change produces a new substance (e.g., burning wood).

  24. What does the pH scale measure, and what is neutral?

    It measures acidity/alkalinity from 0 to 14; 7 is neutral, below 7 is acidic, and above 7 is basic (alkaline).

    Make an observation, form a question, propose a hypothesis, conduct an experiment, analyze the data, and draw a conclusion.

  28. What is the difference between a hypothesis and a theory?

    A hypothesis is a testable, tentative explanation for an observation; a theory is a well-substantiated explanation supported by a large body of evidence.

  29. What is the law of conservation of energy?

    Energy cannot be created or destroyed, only transformed from one form to another; the total energy in an isolated system remains constant.

  30. What is the difference between renewable and nonrenewable energy, with examples?

    Renewable energy is naturally replenished (solar, wind, hydro); nonrenewable energy exists in finite amounts (coal, oil, natural gas).
