22. DIFFERENCES BETWEEN BROWSERS
From a user experience standpoint, most browsers
are the same. The main parts of a web browser are
practically identical and always in the same place,
with minor differences.
If you have used one web browser, you probably
know how to use all the other popular ones.

23. DIFFERENCES BETWEEN BROWSERS
User experience: Each browser looks just a little
different. The buttons are shaped differently, they
might be arranged a little differently, etc. You, as a
user, might have preference over these things.

24. DIFFERENCES BETWEEN BROWSERS
Home screen design: When you first start up a new
browser window, each browser has a different set of
things that it shows you. It might be your bookmarks, or
recently closed windows, or frequently viewed sites. How
you use the internet on a regular basis determines which
type of home screen you might prefer.

25. DIFFERENCES BETWEEN BROWSERS
Apps and plugins: Some web browsers (notably, Chrome but also
Firefox ) have apps, plugins, and addons available, which provide
additional functionality beyond what the browser usually provides.

26. DIFFERENCES BETWEEN BROWSERS
Rendering engine: A web browser has to translate a
bunch of code into a graphical page design that you can
interact with. The sub-program inside the browser that
does that is called the “rendering engine.”

27. DIFFERENCES BETWEEN BROWSERS
Performance: Some browsers load pages faster or slower
than other browsers.
