Overview Of The Computer System Quiz

A scanner is an input device that allows users to convert physical documents or images into digital format. It uses optical technology to capture the information from the document and then transfers it to a computer. This makes it easier to store, edit, and share the scanned documents. Unlike a plotter, tapes, or software, a scanner specifically focuses on capturing physical documents and images, making it the correct answer for the given question.

The "R" in RAM stands for Random. RAM, or Random Access Memory, is a type of computer memory that allows data to be read from and written to in any order, unlike other types of memory that require sequential access. This random access feature allows for faster and more efficient data retrieval and manipulation, making RAM an essential component in computer systems.

MSDOS is not a hardware device because it is an operating system software, not a physical component. It stands for Microsoft Disk Operating System and was commonly used on early IBM-compatible personal computers. It provided the software interface between the computer hardware and the user, allowing them to interact with the system and run applications. Unlike storage devices, output devices, and CPUs, MSDOS does not refer to a physical device that can be touched or connected to a computer.

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.

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.

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.
