What are ‘Eastings’ and ‘Northings’?

The distance is measured on the topographic map. There are two methods of measuring distance on the toposheets,
(i) Direct-method,
(ii) Indirect method.
Measuring straight distance is a direct method and measuring through a winding course is an indirect method. Explain both the methods.
