DefinitionA menu bar (メニューバー) is a strip across the top of an application window that lines up, in a single row, items standing for groups of functions.
ExplanationTypical items are File, Edit and View, and choosing one opens a list of items beneath it (a pull-down menu). The bar itself stays on screen while you work, so users can reach most functions from here.
AnalogyIt is like putting only the chapter titles of a book's contents page on one line; pick a chapter and its sections appear.
Memory hookA bar is a rod. Picture one rod laid across the very top of the screen, with name tags for the functions hung along it.
