Services are JavaScript functions that are designed to perform some specific operation. These services can be called by controllers and filters etc.
There are many built in service available in AngularJS. You can also design Your own custom services.
Some of built-in service are:
$location
$http
$timeout – Works as window.setTimeout in javascript.
$interval – works as window.setInterval in javascript
etc
Using $location service:
app.controller('serviceCtrl', function($scope,$location) { $scope.url = $location.absUrl() });

Using $http Service:
$http service is used most often in AngularJS application. $http service used to make request to the server and getting response.
Myapp.controller('serviceCtrl', function($scope,$http) { $http.get("tryit/angularjs/hello.html").then(function (responseData) { $scope.response = responseData.data; }); });
[/html]
Custom Services:
You can create your own custom service. For that you need to create a service and connect it to module. While creating controller you need to add it as a dependency. After service is created and connected to application, it can be used in any any where like controller, filters or other services.
Num:
Result Square: {{resultDesc}}
myApp.controller('myController', function($scope, customeService) { $scope.multiply = function() { $scope.resultDesc = customeService.multiply($scope.num); } });
