Computer Science Ques 831

Question: The ___________determine how many bits of data can be sent along a given bus at any one time

Options:

A) Control unit

B) Bus width

C) Bus speed

D) Amount of memory

E) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

  • The size of the bus, called the bus width, determines the number of bits that the computer can transmit at one time. For eg. a 32-bit bus can transmit 32 bits (4 bytes) at a time on at 64-bit bus, bits transmit from one location to another 64 bits (8 bytes) at a time. The larger the number of bits handled by the bus, the faster the computer transfers data.
