Information technology (IT) or information and communication technology (ICT) is the technology required for information processing. In particular the use of electronic computers like cellphone and computer software to convert, store, protect, process, transmit, and retrieve information from anywhere, anytime.
Computer Science is a subject in general dealing with computer hardware software. IT is a derived subject which is mainly involved in the management of information using computers.
Both computer science engineers and It engineers develop hardware and software. But the work done by IT engineers are mainly for the management of information.
My advice is ICT. But you can learn web developing at home with a computer with or without the internet.
