Meeting: What is the difference between Gallery and Speaker View?

When in a Zoom meeting, you can toggle between Gallery View (aka Brady Bunch or Hollywood Square view) or Speaker view (larger image for person who is talking). This setting is located in the upper right on a PC/Mac. 

Depending on your computer, you can view 49 people on the screen instead of the default 25. This setting is located on Video Settings (click the caret next to Stop/Start Video on your toolbar). This setting is grayed out if your computer isn't capable of displaying that many images.
