Question

1) Combination of letters and numbers after the period
2) The single number after the period
3) Combination of letters and numbers before the period
4) The single number before the period

Answer 1

The part of the file name that reveals the file type is 1) Combination of letters and numbers after the period.

Step-by-step explanation:

In file naming conventions, the file extension, which is the combination of letters and numbers after the period in the file name, indicates the file type. This extension serves as a code that identifies the format and associated application for opening or interpreting the file. For example, in a file named "document.pdf," the ".pdf" extension signifies that it is a Portable Document Format file. Understanding and recognizing these extensions is crucial for users and systems to correctly interpret and handle different types of files. The combination of letters and numbers after the period is a standardized way of denoting the file format.

Option: A is the answer.
