Questions and Answers

In serial communications, how is a binary number transmitted?

  • Using a clock signal to synchronize data transmission
  • In a mixed format of parallel and serial communication
  • As a sequence of binary digits, one after another, through one data line (correct)
  • Through multiple data lines at the same time
  • What is the primary function of a register in a computer system?

  • Performing arithmetic operations
  • Storing data and states (correct)
  • Generating clock signals
  • Executing logic gates
  • What is the issue with a simple parallel load register using D flip-flops?

  • The register is not compatible with binary counters
  • All n bits can be stored at the same time, which may be undesired (correct)
