Question

A peripheral device used in a word processing system is:
A) Floppy disk
B) Magnetic card reader
C) CRT
D) All of these

Answer 1

Peripheral devices are hardware devices that are used by the computing system to take and display the instructions from the user. These can be input as well as output and include the sensors.
Word processing term is used for the apps or software that enable us to make or edit the documents.

Complete step by step answer:
Peripheral devices are subdivided into three categories:
Input: Takes the instructions from the user and convert it to binary for the computer to carry out processing e.g. keyboard, mouse
Output: Shows the processed output as per the instructions e.g. monitor, printer
Storage: Stores the data for usage e.g. hard disk, CD-ROM.
🡪Peripherals for a computing system and word processing system will be the same.
Checking option by option:
A) Floppy disk: It is a magnetic medium of storage. It is not much used in present times but was famous earlier. Data was stored on concentric (circles with the same center) tracks. It was inserted in a computer in the drive for a floppy disk and was written and read due to its rotation.
B) Magnetic card reader: It is a hardware device used for extracting information from magnetic cards (as used in shops)
C) CRT: It stands for Cathode Ray Tube and is used for producing images using electron beams, it can be monochrome or colored and has a variety of display modes.
It can be seen that all these devices can be used in a word processing system. Therefore, the correct option is D) All of these.

Note: As peripherals are hardware devices, these are connected to the computer through wires. There are different ways of connection (bus, also known as port): parallel or serial depending upon the bit of data.
