What is computer extension example?
Computer extensions are files that have been assigned a specific filename extension, which is recognizable to the computer. These files can be opened and used in the same way as any other file on the computer, with the exception that the extension may dictate the type of file it is. For example, a file with the extension .txt would be a text file, while a file with the extension .jpg would be a JPEG image.
The use of computer extensions allows the computer to recognize the file type and to open it using the appropriate software. This can be helpful, for example, when a user wants to open a file that they know is in a specific format but they are not sure of the file extension. By looking at the filename extension, they can determine the type of file and then open it using the appropriate software.
Another use for computer extensions is to help protect files from being opened accidentally. For example, a user might save a document with the extension .docx, which would indicate to the computer that the file is a Microsoft Word document. This would help to protect the document from being opened by a program that is not compatible with Microsoft Word, such as a PDF reader.
While computer extensions are not required, they can be helpful in identifying and opening specific types of files.
What are examples of extensions?
An extension is a program that adds features to the functionality of another program. Extensions can be installed in a number of ways, including manually, using a software management application, or through a web browser.
There are a number of different types of extensions, including:
– Browser extensions: These are add-ons that can be installed in a web browser in order to add features or improve the user experience. Some popular examples include ad blockers and password managers.
– Application extensions: These are add-ons that can be installed in a desktop or mobile application in order to add features or improve the user experience. Some popular examples include photo editors and note-taking applications.
– Operating system extensions: These are add-ons that can be installed on an operating system in order to add features or improve the user experience. Some popular examples include file managers and task managers.

What is the purpose of file extensions?
File extensions are the letters that come after a period in a computer file name. They tell the computer what type of file it is. For example, the file name “MyDocument.docx” has the extension “.docx” which tells the computer that the file is a Microsoft Word document.
The purpose of file extensions is to help the computer identify the type of file it is. This is important because different types of files require different software programs to open them. For example, a Microsoft Word document can only be opened by a program that is designed to open Microsoft Word documents, such as Microsoft Word or Microsoft Office.
File extensions also help the computer determine how to handle a file. For example, a file with the extension “.jpg” is a picture file, so the computer will know to display the picture when the file is opened. A file with the extension “.doc” is a document file, so the computer will open the document in a word processing program.
Most computer files have one of the following file extensions:
.doc – document
.xls – spreadsheet
.ppt – presentation
.pdf – portable document format
.txt – text file
.jpg – picture
.png – picture
.gif – picture
