PREFACE
Engineers are the makers of modern world. Twentieth century in engineering terms is nothing but the age of computer science. It is very necessary for a computer engineer to get acquainted with the process of networking especially on Linux operating system as per the today’s increasing demand of it
INTRODUCTION TO LINUX
LINUX is an open source / free software. With its advanced server configuration, Red Hat is putting Linux as an operating system at the core of enterprise computing. Today Linux is found in Web infrastructure, file server, ERP, and point of sale system, increasingly in the systems running critical applications at large companies. Analysts predict that by the end of this decade Linux will be a common element in the enterprise computing landscape.
“Over the last year, we’ve seen Linux go from being focused on small and medium business to being used very deep in the enterprise”, says Paul Cormier, executive vice president of engineering at Red Hat, a leading Linux platform provider.
