Choose the correct order how data and information flow in a computer system.
- A.
Process -> information -> data
- B.
Data -> process -> information
- C.
Process -> information -> data
- D.
Information -> process -> data
Correct Answer
B. Data -> process -> informationExplanation
In a computer system, data is the raw input that is processed by the system. The data is then transformed and manipulated through various processes, such as calculations or algorithms. Finally, the processed data is converted into meaningful information that can be understood and used by users or other systems. Therefore, the correct order of data and information flow in a computer system is data -> process -> information.Rate this question:

What stage usually follows the input?
- A.
Output
- B.
Processing
- C.
Saving
Correct Answer
B. ProcessingExplanation
After the input stage, the next stage that usually follows is the processing stage. In this stage, the system or program performs various operations on the input data to produce the desired output. This may involve calculations, manipulations, or transformations of the input data based on predefined algorithms or logic. Once the processing stage is completed, the system moves on to the next stage, which may involve saving or storing the processed data or presenting it as output.Rate this question:

Which of the following might be used during the input stage?
- A.
Mouse
- B.
Printer
- C.
Monitor
- D.
Speakers
Correct Answer
A. MouseExplanation
A mouse is a common input device used to interact with a computer. It allows users to move a cursor on the screen, select items, and perform various actions by clicking buttons. Therefore, a mouse is typically used during the input stage of computer operations. On the other hand, a printer is an output device that produces a hard copy of the information, while a monitor and speakers are also output devices used to display visual and audio output respectively.Rate this question:

Which of the following is NOT an output device?
- A.
Printer
- B.
Mouse
- C.
Speaker
Correct Answer
B. MouseExplanation
A mouse is not an output device because it is used to input information into a computer rather than displaying or producing output. A printer is an output device because it produces physical copies of documents or images. Similarly, a speaker is an output device because it produces sound. However, a mouse is an input device that allows users to navigate and interact with the computer by moving the cursor on the screen.Rate this question:

RAM is non-volatile.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "RAM is non-volatile" is incorrect. RAM (Random Access Memory) is a volatile memory, which means that its data is only stored temporarily and is lost when the power is turned off or when the computer is restarted. Non-volatile memory, on the other hand, retains its data even when the power is turned off. Examples of non-volatile memory include hard drives, solid-state drives, and flash drives.Rate this question:

Data stored in ROM cannot be erased.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
ROM stands for Read-Only Memory, which means that it is designed to store data that cannot be modified or erased. Unlike other types of memory such as RAM, which is volatile and can be written to and erased, the data stored in ROM is permanently written during the manufacturing process and cannot be changed. Therefore, the statement that data stored in ROM cannot be erased is true.Rate this question:

RAM and ROM ...
- A.
Read Application Memory and Read Office Management
- B.
Read Area Memory and Read Ounce Memory
- C.
Random Application Management and Read Office Memory
- D.
Random Access Memory and Read Only Memory
Correct Answer
D. Random Access Memory and Read Only MemoryExplanation
The correct answer is "Random Access Memory and Read Only Memory". RAM is a type of computer memory that allows data to be read from and written to quickly, making it ideal for running programs and storing temporary data. ROM, on the other hand, is a type of memory that stores permanent data and instructions that cannot be modified or erased. It is used to store firmware and other essential data that is required for the computer to start up.Rate this question:

- 13.
RAM is considered to be the temporary memory ...
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
RAM (Random Access Memory) is considered to be the temporary memory in a computer system. It is used to store data and instructions that are actively being used by the CPU (Central Processing Unit). Unlike permanent storage devices such as hard drives, RAM is volatile and its contents are lost when the computer is powered off. Therefore, it is commonly referred to as temporary memory. This makes the statement "RAM is considered to be the temporary memory" true.Rate this question:

We save pictures in the ROM.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is false. We do not save pictures in the ROM (Read-Only Memory). ROM is a type of memory that stores data permanently and cannot be modified or erased. Pictures are typically saved in other types of memory such as the hard drive, solid-state drive, or flash memory. These types of memory allow for the storage and modification of data, unlike ROM.Rate this question:

To calculate weather forecasting, one would need a ....
- A.
Laptop
- B.
Desktop pc
- C.
Tablet
- D.
Supercomputer
Correct Answer
D. SupercomputerExplanation
To calculate weather forecasting accurately, a supercomputer is needed. This is because weather forecasting involves complex mathematical calculations and simulations that require immense processing power. Supercomputers are specifically designed to handle large amounts of data and perform calculations at incredibly high speeds. Their advanced capabilities allow meteorologists to analyze vast amounts of data, including atmospheric conditions, temperature patterns, and historical weather data, to generate accurate forecasts. Standard laptops, desktop PCs, and tablets do not possess the necessary computational power and capabilities to handle the extensive calculations and data processing required for weather forecasting.Rate this question:
