Question

File type can be represented by

a) file name
b) file extension
c) file identifier
d) none of the mentioned

Answer 1

The file type is typically represented by the file extension, a sequence of characters at the end of a file name that helps identify the format of the file.

Step-by-step explanation:

File type can often be represented by the file extension, which is a short sequence of characters appended to the end of a file name. The file extension usually follows a period (.) and helps the operating system determine which program should be used to open the file. For example, a '.txt' extension indicates a text file, and a '.jpeg' extension indicates a JPEG image file. While the file name can give an idea of the content, it is the file extension that typically represents the type and format of the file. Therefore, the correct answer is b) file extension.
