SPOOLING and SPOOLED Devices
SPOOLING stands for Simultaneous Peripheral Operations On-Line. It is a technique used in computer systems to improve the efficiency and speed of input/output (I/O) operations. SPOOLING allows multiple I/O operations to be performed simultaneously, which reduces the waiting time for the user.
A SPOOLED device is a device that uses SPOOLING to manage its I/O operations. In other words, a SPOOLED device is a device that can handle multiple I/O requests simultaneously using SPOOLING.
Example of a SPOOLED Device
The correct answer to the given question is option C, which says "A line printer used to print the output of a no. of Jobs." Let's understand why it is an example of a SPOOLED device.
A line printer is a type of printer that can print a large number of lines of text on a paper. It is commonly used in offices and businesses to print reports, invoices, and other documents. When a line printer is used to print the output of a no. of jobs, it becomes a SPOOLED device.
Here's how it works:
1. When a user submits a print job to the line printer, the job is first spooled into a buffer in the computer's memory.
2. The spooled job is then placed in a queue, along with other jobs waiting to be printed.
3. The line printer uses SPOOLING to retrieve the jobs from the queue and print them one by one.
4. While one job is being printed, the other jobs are waiting in the queue, ready to be printed as soon as the printer is available.
5. This way, the line printer can handle multiple print jobs simultaneously, without any waiting time for the user.
Conclusion
In conclusion, a SPOOLED device is a device that uses SPOOLING to manage its I/O operations. The line printer used to print the output of a no. of jobs is an example of a SPOOLED device, as it can handle multiple print jobs simultaneously using SPOOLING.
