Models use getters and setters but the binding is automatically and better than Backbone.
Used for routing your applications URL's when using hash tags(#) and/or HTML5 history API
Maps an url to a javascript function
ROUTERS
/person/12/101
Routing is very simple
Router is similar to Backbone’s
/person/12/101
Router is extremely capable, but very complex
Supported embedded routes
/person/12/101
Knockout does not support routing by default
Still Routing is easily configurable by following third party libraries
VIEWS
How the stuffs are displayed in the screen

Fantastic test support. Designed from the beginning to be easy to test. Karma developed by Angular JS team is popular test runner
Poor testing initially Pretty good testing support now
As of now, no default debugging tools Functions like Console.log(), ko.toJSON() helps debugging process
Can use following third party solutions
DATA
How do I get data from the sever?
Uses JQuery’s $.ajax to power Backbone. Very Easy to understand Default behaviour is relatively easy to override
No JQuery
Can do with Angular’s $http but much better using $resource
Very good API
Requires the ngResource module to be installed.
Uses JQuery’s $.ajax under the covers
Just “getting data” is relatively easy to do e.g.
Doing things the “Ember way” is a bit more complex
Uses JQuery’s $.ajax
Uses knockout mapping plugin
Maps JavaScript object into a view model with the appropriate observables
