That is a good question. IT technology is such a vast field that every department of IT like networking, security, banking,web development etc are equally important. But with the recent trends in the world I will recommend networking and IT security as two important fields where you can take a chance.
Even when you think from salary side this two fields are in demand. But I recommend after doing your degree, do some training in networking and security. Some IT training institute in Bangalore, India are providing good training
facilities. As you know India is top destination for learning IT and software and more over the fees are less.
