Step by step solution

01

Definition of an Output File

An output file is a file onto which a computer program writes its results, processed data, or any other information that is generated during the execution of the program. The data stored in an output file can be human-readable text, numbers, graphics, or any other type of information that is generated during the operation of a specific program.
02

Purpose of an Output File

Generally, output files are created when the program requires to store or export data that has been processed, allowing the user to read, analyze, or manipulate it further. Output files can be used for several purposes, such as sharing information with others, backing up data or results, analyzing the outcome of computations or simulations, and many more.
03

Examples of Output Files

For instance, imagine you are working with a software application that performs statistical analysis on a dataset made up of regularly measured numerical values. After completing the analysis, the software application might write the results into a text (.txt), CSV (.csv), or Excel (.xlsx) file. This output file contains a summary of the statistical analysis, including information such as the mean, median, variance, and other descriptive statistics. The user can then open this output file in a suitable program to review the analysis and make decisions based on the results.
