Which of the following statements is true about ROM?
- A.
New data can be written to ROM.
- B.
H is non-volatile.
- C.
The contents are lost when the computer Is turned off.
- D.
It is volatile.
Correct Answer
B. H is non-volatile.Explanation
ROM stands for Read-Only Memory, which means that the data stored in ROM cannot be modified or written to once it is programmed during manufacturing. It is non-volatile, which means that the data remains intact even when the computer is turned off. This is in contrast to volatile memory, such as RAM, where data is lost when the power is turned off. Therefore, the statement "H is non-volatile" is true for ROM.Rate this question:

If a file allows direct access. what does that mean?
- A.
The computer has read-only access to the file.
- B.
The computer can Immediately read any record in the file.
- C.
The file is printed out so you can read it directly.
- D.
You do not need a password to access the file.
Correct Answer
A. The computer has read-only access to the file.Explanation
If a file allows direct access, it means that the computer has read-only access to the file. This means that the computer can retrieve information from the file, but cannot make any changes or modifications to it. Direct access allows the computer to immediately read any record in the file, without the need for sequential searching or scanning through the entire file. It does not mean that the file is printed out or that no password is required to access it.Rate this question:

Which of these features is essential for a process control application?
- A.
Human-readable documents
- B.
Wi-Fi connectivity
- C.
Sensor input
- D.
Graphical interface
Correct Answer
C. Sensor inputExplanation
A process control application requires sensor input in order to monitor and control various parameters of a process. This input allows the application to gather real-time data and make necessary adjustments to ensure optimal performance. Human-readable documents may be helpful for documentation purposes, but they are not essential for the application itself. Wi-Fi connectivity and a graphical interface may enhance the functionality and user experience, but they are not essential features for the basic operation of a process control application.Rate this question:

Which of the following is an appropriate application for a super computer?
- A.
Word processing
- B.
Weather forecasting
- C.
3D gaming d Payroll Processing
- D.
Payroll processing
Correct Answer
B. Weather forecastingExplanation
Weather forecasting requires complex mathematical calculations and simulations that involve large amounts of data. Supercomputers are specifically designed to handle these types of tasks, as they have the capability to process and analyze massive amounts of data at incredibly high speeds. This makes them ideal for applications such as weather forecasting, where accurate and timely predictions are crucial. Word processing, 3D gaming, and payroll processing can be performed on regular computers or even smartphones, as they do not require the same level of computational power as weather forecasting.Rate this question:
