A ________ consists of many columns and rows?

Appeared in: AIIMS Manglagiri NO - 2019

Explanation

A table is a data structure that organizes information into a grid.
This grid is composed of vertical columns and horizontal rows.
The intersection of a row and a column is called a cell, which holds a specific piece of data.
This structure allows for easy reading, comparison, and analysis of data.

Option A: A printer is a hardware device used for printing documents. It is an output device and is not a data structure composed of columns and rows.
Option C: Format refers to the layout, style, or arrangement of data (e.g., font size, color, bolding). It describes the appearance of data, not the underlying grid structure.
Option D: 'Word' can mean a unit of language or a software application (Microsoft Word). Neither definition describes a structure of columns and rows.

Understanding tables is crucial for nurses to accurately read and interpret patient data, such as vital signs charts, medication administration records (MAR), and laboratory results, which are almost always presented in a tabular format.
Nurses use tables to document patient assessments, interventions, and outcomes in electronic health records (EHRs). Proper data entry into the correct rows and columns is essential for patient safety and continuity of care.
