What is the function of target="_blank" in HTML links?

The function of target="_blank" in HTML links is to instruct the web browser to open the linked document in a new tab or window. This allows users to access the new link without losing their current page, which can enhance user experience by allowing easy navigation back and forth between the original page and the new content.

When a link is specified with target="_blank", it effectively enables the user to explore supplementary information or resources while keeping the primary webpage intact. This is particularly useful for external links, as it maintains the user's presence on the originating site.

Options that suggest redirecting to an internal page, creating an unclickable link, or embedding a video do not pertain to the function of target="_blank". Instead, they relate to different aspects of HTML and web development that do not involve the mechanism of opening links in new tabs or windows.
