What type of memory is nonvolatile, considered permanent, and is also called firmware in reference to the data and instructions stored?
- A.
RAM
- B.
ROM
- C.
Cache
- D.
CMOS
Correct Answer
B. ROMExplanation
ROM stands for Read-Only Memory. It is a type of memory that is nonvolatile, meaning it retains its data even when the power is turned off. ROM is considered permanent because its contents cannot be easily changed or erased. It is also referred to as firmware because it contains the permanent instructions that are necessary for a computer or electronic device to boot up and perform basic functions. Unlike RAM (Random Access Memory), ROM cannot be written to or modified by the user. Therefore, ROM is the correct answer for this question.Rate this question:

Which type of memory is used to duplicate frequently used information stored elsewhere or computed earlier, because the original data is time consuming to retrieve or to compute?
- A.
RAM
- B.
ROM
- C.
Buffer
- D.
Cache
Correct Answer
D. CacheExplanation
Cache memory is used to duplicate frequently used information stored elsewhere or computed earlier because the original data is time-consuming to retrieve or compute. Cache memory is a small, high-speed memory that is located closer to the CPU than main memory (RAM) or secondary storage (ROM). It stores a copy of frequently accessed data, allowing the CPU to access it quickly without having to retrieve it from the original source. This helps to improve overall system performance by reducing the time it takes to access data.Rate this question:

Which is a very simple example of an error detecting code?
- A.
Parity bit
- B.
Interrupt
- C.
Data integrity
- D.
Asynchronous
Correct Answer
A. Parity bitExplanation
A parity bit is a very simple example of an error detecting code. It is used to detect errors in data transmission by adding an extra bit to the binary code. This extra bit is set to either 0 or 1, depending on the number of 1s in the data. If the number of 1s is even, the parity bit is set to 0, and if the number of 1s is odd, the parity bit is set to 1. When the data is received, the parity bit is checked, and if it doesn't match the expected value, an error is detected. This allows for the detection of single-bit errors.Rate this question:

- A.
Printer's language
- B.
Driver's language
- C.
Processor's language
- D.
Print server's language
Correct Answer
A. Printer's languageExplanation
When a print job is spooled, it is temporarily stored in a print queue before being sent to the printer. The printer's language refers to the specific language or format that the printer understands. This language is used to convert the print job into a format that the printer can interpret and print. Since the printer's language is more complex and contains additional information compared to the original document, the spooled print job can be several times larger in size.Rate this question:
