This is the most commonly asked question-sort of. An application and a tab are the same things. Here is a quote: when Sociomee carried out the new Timeline profile plan for business Pages, the expression “tab” was constrained into termination and supplanted by “application.” With Timeline, applications (officially known as tabs) have a more complex plan, like an object page on a conventional site. In synopsis, today, many individuals allude to an application as a tab even though the expression “tab” is, at this point, not right.
