Distance

Hello Priya,
If you have a core degree like M.Sc and MCA and then you will do some certification through distance, it will be beneficial but if you are going to do a core course or degree in IT field through distance, this will be not be beneficial for you as IT is a technical field and also contain practicals as well. Most of the IT firms does not consider distance degree while they hire.
if you have a Bachelors degree in IT then I will suggest you to do some certification depend on your interest like adv. java, php, .Net, web designing, software testing etc and once you get a job you can plan of pursuing M.Sc form distance.
