Tag
In computing, a tag is a label or keyword used to categorize or identify a piece of data, information, or content. It can also refer to a markup element in a document, such as in HTML, which provides instructions to the computer on how to display or format the content. Additionally, a tag can be a unique identifier, like a serial number sticker on a computer, used for tracking and management.
Types of tags
Markup tags: These are codes embedded in a document, often enclosed in angle brackets, that define the structure or format of the content.
Metadata tags: These are used to provide information about a file or piece of data.
Categorization tags: These are keywords or labels that organize content for users and search functions.
Identifier tags: A physical or digital label with a unique code assigned to an individual device for tracking and management.
Programming tags: In some programming languages, a tag is an argument that determines how other arguments are passed to a subroutine.
