B. PlotterExplanation
A plotter is an output device that is used to create high-quality graphics and images on paper. It is commonly used in architectural and engineering applications to produce large-scale drawings and designs. Unlike other output devices like scanners or printers, a plotter uses pens or pencils to draw lines directly onto the paper, resulting in precise and detailed output. Therefore, a plotter is the correct answer as it is specifically designed for outputting graphical information onto paper.Rate this question:

Correct Answer
B. UNIXExplanation
UNIX is a multi-tasking operating system because it allows multiple tasks or processes to run simultaneously. It has the ability to manage and distribute system resources efficiently among different applications or users. This means that multiple users can access the system and run various programs or tasks concurrently without interfering with each other. UNIX's multi-tasking capability makes it a preferred choice for servers and high-performance computing environments where multiple processes need to be executed simultaneously.Rate this question:

Read only memory
- B.
Cartridge tapes
- C.
Magnetic disk
- D.
Magnetic tapes
Correct Answer
A. Read only memoryExplanation
Read only memory (ROM) is not a secondary storage medium because it is a type of non-volatile memory that stores data permanently and cannot be modified or overwritten. Unlike secondary storage mediums such as cartridge tapes, magnetic disks, and magnetic tapes, ROM is used primarily for storing firmware and software instructions that are essential for booting up a computer or electronic device. Secondary storage mediums, on the other hand, are used for long-term storage of data and can be read from or written to by the computer or device as needed.Rate this question:
