Which of the following file contains huge data in compressed form?

Appeared in: AIIMS Raipur NO - 2019 (Shift-1)

Explanation

A Zip file is an archive file format specifically designed for lossless data compression.
Its main purpose is to reduce the storage size of one or more files by bundling them into a single, smaller file.
This makes it the ideal choice for storing large amounts of data or for transferring data over networks more efficiently.

Option A: A backup file is a copy of data created for recovery purposes. While backup files can be compressed to save space, their defining feature is their role in data protection, not the compression method itself.
Option B: A PDF (Portable Document Format) file is used to present documents in a manner independent of application software, hardware, and operating systems. It uses internal compression for its own elements (like images and text), but it is not a general-purpose tool for a user to compress any type of file.
Option C: An executable file (.exe) contains a set of instructions for a computer's central processing unit (CPU) to execute a program. It is not designed for storing or compressing user data.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Understanding of common computer file types and their primary functions, specifically data compression as background academic context rather than a clinical decision trigger.
While this is a general knowledge question, understanding file types is crucial for managing digital patient records, research data, and administrative documents in modern healthcare.
Knowing how to use Zip files helps in securely and efficiently sharing large medical imaging files (like DICOM folders) or patient data sets with colleagues or for research, while complying with privacy regulations.
What if? If a nurse needed to email a folder containing multiple patient education pamphlets to a patient, zipping the folder into a single file would be the most efficient and organized method for sending them as one attachment.

How to Approach the Question

First, identify the core requirement of the question, which is to find a file type whose main purpose is to store 'huge data in compressed form'.
Evaluate each option based on its primary function in a computer system.
Recognize that 'Backup file' describes a purpose (data safety), not a specific file format.
Note that 'PDF file' is for document presentation and 'Executable file' is for running programs.
Conclude that 'Zip file' is the only option specifically designed for the purpose of compressing one or more files, directly matching the question's requirement.
