Internet address is a

  • A.8-bit number
  • B.16-bit number
  • C.32-bit number
  • D.None of these

Answer: C

The key's answer is a 32-bit number.

An IPv4 address, the classic internet address, is 32 bits long. It is written as four 8-bit numbers in dotted decimal form, such as 192.168.1.1, giving about 4.3 billion possible addresses.

8 and 16 bits are far too small; 8 bits is just one part of the dotted address. The newer IPv6 addresses are 128 bits long, but the question refers to the familiar IPv4 address.
