Find answers to this self-test at the back of the book: Answers for Self-Tests
True or false
- A vacuum tube is an electronic device that controls the flow of electrons in a vacuum.
- A transistor is an electronic component held on an integrated circuit that contains a computer’s CPU and other associated circuits.
- A magnetic drum uses arrays of small rings of magnetized material called cores to store information.
- Assembly language is like the machine language that a computer can understand, except that assembly language uses abbreviated words in place of numbers.
- Internal hardware devices are any hardware device that is located outside the computer.
- Hardware is a set of instructions or programs that tells a computer what to do or how to perform a specific task.
- 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.
- Utility software is a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task.
