1.
What is an algorithm?
Correct Answer
A. A set of steps in order approach to solve a problem
Explanation
The correct answer is a set of steps in order approach to solve a problem. An algorithm is a systematic approach to problem-solving that involves a sequence of steps or instructions. It provides a clear and logical way to solve a problem by breaking it down into smaller, manageable steps. Algorithms can be written in various forms, including in English or code, and they follow specific rules and conventions of the chosen language.
2.
What is pseudocode?
Correct Answer
A. Algorithm wirtten in english or code
Explanation
Pseudocode refers to an algorithm written in English or code. It is a way of representing a solution to a problem using a combination of natural language and basic programming constructs. Pseudocode is not a formal programming language, but rather a simplified and informal representation of the logic and steps involved in solving a problem. It allows programmers to plan and communicate their ideas before writing actual code, making it easier to understand and debug the solution.
3.
What is a loop?
Correct Answer
A. A series of repeated instructions
Explanation
A loop is a programming construct that allows a series of instructions to be repeated multiple times. It is a way to automate the execution of a set of instructions without having to write them out individually each time. By using a loop, the same set of instructions can be executed over and over again until a specific condition is met. This helps in reducing code redundancy and making the program more efficient.
4.
The cpu could be most compared to what body part?
Correct Answer
B. head/brain
Explanation
The CPU (Central Processing Unit) is often compared to the head/brain because, like the brain, it is the central component responsible for processing and executing instructions in a computer system. The CPU performs calculations, makes decisions, and controls the overall functioning of the computer, just as the brain does for the human body. Both the CPU and the brain are essential for the proper functioning of their respective systems.
5.
The keyboard will be used to . . .
Correct Answer
C. Answers a and b
Explanation
The keyboard will be used to type information and make pictures. This means that it can be used to input text and also create visual images.
6.
Which of the following is NOT a field of engineering?
Correct Answer
D. Metal Engineering
Explanation
Metal Engineering is not a recognized field of engineering. While Aerospace Engineering, Audio Engineering, and Industrial Engineering are all well-established fields of engineering, Metal Engineering is not commonly recognized as a separate discipline. It is possible that Metal Engineering may refer to a specialization within another field, such as Materials Engineering, but it is not typically considered a distinct field on its own.
7.
What is debugging?
Correct Answer
A. Running the program to identify and remove errors
Explanation
Debugging refers to the process of running a program in order to identify and eliminate errors or bugs. It involves analyzing the code, tracking down the source of the problem, and making necessary corrections to ensure the program functions correctly. By running the program and observing its behavior, developers can identify and fix any issues that may arise, ensuring the program operates as intended.
8.
The computer monitor is more like a
Correct Answer
A. television
Explanation
The computer monitor is more like a television because both devices are used for displaying visual content. They both have screens that can show images, videos, and other multimedia. Additionally, they share similar features such as adjustable brightness, contrast, and resolution settings. Both televisions and computer monitors are designed to provide a visual viewing experience, making them more alike compared to the other options listed.
9.
The action of driving or pushing forward.
Correct Answer
A. Propulsion
Explanation
Propulsion refers to the action of driving or pushing forward. It is the force that propels an object or vehicle in a specific direction. In this context, propulsion is the most suitable term as it accurately describes the action of driving or pushing forward. Rotate refers to the act of turning or spinning, movement is a more general term that can encompass various types of motion, and backwards refers to the opposite direction of forward. Therefore, propulsion is the correct answer in this case.
10.
In general terms Fulcrum is the middle point on which all things balance
Correct Answer
A. True
Explanation
The given statement is true. In general terms, a fulcrum is indeed the middle point on which all things balance. A fulcrum is a pivot point or a point of support that allows for the movement or balance of objects. It is commonly used in physics and engineering to understand the principles of levers and other mechanical systems. The correct answer is true because the statement accurately describes the concept of a fulcrum.
11.
A Gear is?
Correct Answer
D. One of a set of toothed wheels that work together
Explanation
The correct answer is "one of a set of toothed wheels that work together." This explanation accurately describes what a gear is - a toothed wheel that engages with other gears to transmit power and motion. Gears are commonly used in machinery and vehicles to control speed, torque, and direction.
12.
A ____________ is a wheel on an axle or shaft that is designed to support movement
Correct Answer
B. Pulley
Explanation
A pulley is a wheel on an axle or shaft that is designed to support movement. It is used to change the direction or magnitude of a force applied to a rope or belt that is wrapped around it. By using a pulley, it becomes easier to lift heavy objects or move them in different directions. Pulleys are commonly used in various applications such as elevators, cranes, and conveyor belts.
