- 1.
This is the stage where data or instructions are put into a computer system.
- A.
Information
- B.
Input
- C.
Process
Correct Answer
B. InputExplanation
This is the stage where data or instructions are put into a computer system. Input refers to the process of providing data or commands to a computer system for processing. It involves transferring data from an external source, such as a keyboard, mouse, or storage device, to the computer's memory for further processing. Input is an essential step in the overall operation of a computer system as it allows users to interact with the system and provide the necessary information for carrying out tasks and executing programs.Rate this question:

Which of the following best describes the concept of data entropy in information theory?
- A.
The measure of the randomness or unpredictability of data.
- B.
The process of compressing data to reduce its size.
- C.
The mathematical formula for calculating the information content of data.
- D.
The principle that data should be organized in a hierarchical structure for efficient retrieval.
Correct Answer
A. The measure of the randomness or unpredictability of data.Explanation
Data entropy, in the context of information theory, refers to the measure of the randomness or unpredictability of data. It quantifies the amount of uncertainty or disorder in a dataset. High entropy indicates that the data is more unpredictable or random, while low entropy suggests that the data is more structured and predictable. Entropy is often used in various fields, such as data compression, cryptography, and machine learning to characterize the information content or complexity of datasets. Therefore, option (a) accurately describes the concept of data entropy and its significance in information theory.Rate this question:

Complete this equation:Data + _________________ = Information
Correct Answer
MeaningExplanation
Data by itself is simply raw facts and figures. It is only when data is given meaning or interpretation that it becomes information. Meaning is the missing element in the equation that transforms data into something useful and understandable.Rate this question:
- 4.
These are raw facts, figures, values or instructions with no specific meaning by themselves.
- A.
Information
- B.
Data
- C.
Meaning
Correct Answer
B. DataExplanation
Data refers to raw facts, figures, values, or instructions that have no specific meaning on their own. It is unprocessed information that needs to be organized, analyzed, and interpreted to derive meaningful insights or conclusions. Data is the foundation for generating information and acquiring knowledge. Without proper analysis and interpretation, data remains meaningless and lacks any significant value. Therefore, data is the correct answer as it represents the raw and unprocessed form of information.Rate this question:
-
- 5.
This is processed information that comes out of a computer system.
- A.
Input
- B.
Process
- C.
Feedback
- D.
Output
Correct Answer
D. OutputExplanation
Output refers to the processed information that comes out of a computer system. It is the final result or the outcome of the input that was provided to the system and went through the processing stage. Output can take various forms such as text, images, sounds, or any other form of data that can be presented to the user or used for further processing. It is the end product of the system's operations and is generated based on the input and the algorithms or instructions followed during the processing stage.Rate this question:

_________________ is data that has been given a meaning or context.
Correct Answer
InformationExplanation
Information refers to data that has been processed, organized, or interpreted in a way that gives it meaning or context. It is the result of analyzing and understanding data, making it useful and meaningful for decision-making or understanding a specific topic or situation. Information provides insights, knowledge, and understanding that can be used to make informed decisions or take appropriate actions.Rate this question:

Computer systems are made up with _________________ and software.
Correct Answer
HardwareExplanation
Computer systems are made up of hardware and software. Hardware refers to the physical components of a computer system, such as the processor, memory, motherboard, and peripherals. These components are tangible and can be touched and seen. On the other hand, software refers to the programs, applications, and data that run on the hardware. It is intangible and consists of instructions that tell the hardware what to do. Both hardware and software are essential for a computer system to function properly.Rate this question:
- 8.
Which three of these are examples of hardware.
- A.
Printer
- B.
Motherboard
- C.
Printer Driver
- D.
Monitor
Correct Answer(s)
A. Printer
B. Motherboard
D. MonitorExplanation
The three examples of hardware mentioned in the options are Printer, Motherboard, and Monitor. Hardware refers to physical components of a computer system that can be touched and interacted with. A printer is a hardware device used to produce a physical copy of documents or images. A motherboard is a main circuit board that connects and allows communication between various components of a computer. A monitor is an output device that displays visual information from the computer. Therefore, these three options are examples of hardware components.Rate this question:

In a computer system, the stage between input and output is called __________________.
Correct Answer(s)
processing, ProcessingExplanation
The stage between input and output in a computer system is called the processing. This refers to the series of actions or operations performed on the input data to produce the desired output. During the processing stage, the input is analyzed, manipulated, and transformed according to the instructions given by the user or the program. This includes tasks such as data processing, calculations, decision-making, and any other necessary operations. Once the processing is completed, the output is generated and made available to the user or sent to the output devices.Rate this question:

GIGO is the acronym used for what?
- A.
Go In Go Out
- B.
Garbage In Garbage Out
- C.
Get In Get Out
Correct Answer
B. Garbage In Garbage OutExplanation
The acronym GIGO stands for "Garbage In Garbage Out." This phrase is commonly used in computer science and information technology to emphasize that the quality of output is determined by the quality of input. It suggests that if incorrect or low-quality data is entered into a system, the resulting output will also be incorrect or low-quality. This principle highlights the importance of ensuring accurate and reliable input to obtain desired and meaningful output.Rate this question:
