Operating System is the most important and the most fundamental piece of software. It provides you the superb abstraction to the physical machinery (i.e device drivers), it manages the resources available to you (Memory Management, Process Management and File System) and it gives you an interface/abstraction which looks quite natural to work on. It's an interesting field, with a strong history - lot of innovations as well as lot of business stories to its credit.

Though the traditional issues related with operating systems are no longer hot as research topics, internetworking, multimedia support and ubiquitous computing still demands new innovations in this field.
