Consider the following statements:
1.Digital divide exists between developed and developing countries
2.Digital divide can be between urban and rural areas
3.Digital divide happens only between two countries and not within countries

Only 1 and 2 is true 

Digital divide exists between developed and developing countries and it can be between urban and rural areas. Digital divide happens not only between two countries and also within countries areas like metropolitan centres which possess better connectivity and access to the digital world versus peripheral rural areas which lack this facility.
