Sorry for being little sarcastic in above post. In fact, any field of computer science has huge scope. Don't go on job scopes and which one pays more. If you want to jump to IT, look for what is so appealing for you. There are dozens of field you chose in IT related. And remember, unlike many other field, no trainings and degrees can take you to high figure salary. You need to self propelled and really interested on what you do. If not, you must have seen lots of people struggling in getting jobs in IT.
