Worked practice questions

A browser turns a typed web address into a long number that identifies the machine. That number is an:

  1. IP address
  2. IT address
  3. ID address
  4. IX address
Show answer and solution

Correct answer: A. IP address

1. A name means nothing to the machines carrying the data. 2. They route by a numeric label instead, much like a phone number. 3. That label is the IP address. _Source: OpenStax Introduction to Computer Science, Chapter 5, Computer Systems Design._
