ITPEC IP April 2022 Question 78
Mr. X stores images taken by a digital camera in a storage medium, inserts the storage medium in a printer, and prints them. It is possible to print the images without taking into consideration the manufacturer of the digital camera. Which of the following is the technical premise concerning image data that enables this?
Explanation
Standardization — cameras and printers follow the same standards for image data, so any printer can read any camera's pictures.
Digital cameras record images in standard file formats (JPEG with Exif information) and in a standard folder and file layout on the storage medium (DCF). A printer built to the same standards can find and print the images regardless of who made the camera. Interoperability between different manufacturers' products is the purpose of standardization.
Answer (c)
Why not others:
- •(a) Commoditization — products becoming so alike that they compete only on price; a result of standardization at most, not what makes the data readable
- •(b) Networking — connecting devices over a network; here the data travels on a storage medium
- •(d) Ubiquity — computers and networks being available anywhere at any time; it says nothing about a shared data format
Key rule: When products of different makers work together without special arrangements, the premise is a common standard for the data or interface.
