  1. What is the binary equivalent of the decimal number 13?

    Answer: 1101

    Decimal 13 = 8+4+1 = 1101 in binary (8=1, 4=1, 2=0, 1=1).

  2. What logic gate outputs HIGH only when all inputs are HIGH?

    Answer: AND gate

    An AND gate produces a HIGH (1) output only when all of its inputs are simultaneously HIGH (1).

  3. What is the hexadecimal equivalent of binary 1010 1111?

    Answer: AF

    1010 = A and 1111 = F in hexadecimal, so 10101111 = AF hex.

  4. Which type of memory loses its data when power is removed?

    Answer: RAM

  5. What does the term 'bit' refer to in digital electronics?

    Answer: A single binary digit (0 or 1)

    A bit (binary digit) is the smallest unit of digital information, represented as either a 0 or a 1.

  6. In avionics, what bus protocol uses a single twisted pair for bidirectional data at 1 Mbps?

    Answer: MIL-STD-1553

    MIL-STD-1553 is a military avionics bus standard that uses a single shielded twisted pair for half-duplex, command/response data at 1 Mbps.
