There aren't really any development fields more challenging than operating system OS development. It is the " great pinnacle of programming. Few programmers ever attempt to build an OS and many of those who do make the attempt never produce a functioning system. However, if you do make it all the way to the finish line and produce a functional operating system, you will have joined an elite group of top-flight programmers. Every program that ran on these early systems had to include all of the code necessary to run the computer, communicate with connected hardware, and perform the computation the program was actually intended to perform. This situation meant that even simple programs were complex. As computer systems diversified and became more complex and powerful, it became increasingly impractical to write programs that functioned as both an operating system and a useful application.

The book is centered around three conceptual pieces that are fundamental to operating systems: virtualization, concurrency, and persistence. In understanding the conceptual, you will also learn the practical, including how an operating system does things like schedule the CPU, manage memory, and store files persistently. Lots of fun stuff! Or maybe not so fun? This book is and will always be free in PDF form, as seen below. For those of you wishing to BUY a copy, please consider the following:.

Real-time operating system RTOS is an operating system intended to serve real time application that process data as it comes in, mostly without buffer delay. It is time-bound system that can be defined as fixed time constraints. In this type of system, processing must be done inside the specified constraints. Otherwise, the system will fail.

A network operating system NOS is a specialized operating system for a network device such as a router , switch or firewall. Historically operating systems with networking capabilities were described as network operating system, because they allowed personal computers PCs to participate in computer networks and shared file and printer access within a local area network LAN. This description of operating systems is now largely historical, as common operating systems include a network stack to support a client—server model. Historically a network operating system was an operating system for a computer which implemented network capabilities.

An Operating system is an essential part in any computer system. There is a huge demand for OS developers in the IT industry. To build a career as an Operating System developer, candidates need to crack the interview in which they are asked for various Operating System interview questions.
