Find answers to this self-test at the back of the book: Answers for Self-Tests

True or false

1. A vacuum tube is an electronic device that controls the flow of electrons in a vacuum.
2. A transistor is an electronic component held on an integrated circuit that contains a computer’s CPU and other associated circuits.
3. A magnetic drum uses arrays of small rings of magnetized material called cores to store information.
4. Assembly language is like the machine language that a computer can understand, except that assembly language uses abbreviated words in place of numbers.
5. Internal hardware devices are any hardware device that is located outside the computer.
6. Hardware is a set of instructions or programs that tells a computer what to do or how to perform a specific task.
7. Operating system (OS) is a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer. It is the main part of system software and the computer will not function without it.
8. Utility software is a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task.
