Digital Computers And Humans Quiz

1. Which numbers are examples of binary digits?

0 and 1

1 and 2

0 and 3

2 and 4

Binary digits, also known as bits, are the fundamental building blocks of binary number system. They can only have two possible values, 0 and 1. Therefore, the numbers 0 and 1 are examples of binary digits.

2. What defines a digital computer?

A computer that represents information using the ABCs

A computer that can walk like a human

A computer that represents information by numerical binary digits

A computer that can be bought in the store

A digital computer is defined as a computer that represents information using numerical binary digits. This means that the computer uses a binary system composed of 0s and 1s to represent and process data. Unlike analog computers that use continuous values, digital computers use discrete values to perform calculations and store information. This binary representation allows for precise and accurate calculations, making digital computers widely used in various fields such as science, engineering, and business.

3. Which of these is an example of a cyborg?

A dog

A robot

A girl with a mechanical leg

An alien

A cyborg, short for "cybernetic organism," refers to a being that combines both biological and artificial components. In this case, a girl with a mechanical leg fits the definition of a cyborg as she has a biological body (the girl) combined with an artificial component (the mechanical leg). The other options, such as a dog, a robot, and an alien, do not involve the integration of artificial components with a biological entity.

4. The three parts of a digital computer are:

A digital computer consists of three main components: store, executive unit, and control. The store refers to the memory of the computer where data and instructions are stored. The executive unit is responsible for executing instructions and performing calculations. The control unit manages the flow of data and instructions between the store and the executive unit, ensuring that the correct instructions are executed in the proper sequence. These three components work together to enable the functioning of a digital computer.
