difficulty understanding ActionBar and ifRoom

private void setUpActionBar() {
// Make sure we're running on Honeycomb or higher to use ActionBar APIs
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    ActionBar actionBar = getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
}
}

What is ActionBar ? Is it a pop-up window or an activity or something else ?

One more question, why do we need to use 'ifRoom' argument in android:showAsAction attribute ?
