To start a chapter on network operating systems, there is a need to build some definitions and discuss the modern goals of software design. Object-oriented programming is a good place to begin discussing network operating systems. Their advantages include: reduced development time, better organization of programming efforts, and reusable code. Today, any modern network system used in either commercial or industrial applications should be object-oriented and have a good “object model”. Object-oriented programs have classes of objects. The concept of “class” can be explained by an example: a class of objects known as ________

The big push commercially is “cloud” computing, this is an effort to again penetrate the subscription market. Office 365 is a good example of an application living in the cloud; for a monthly fee you have an up-to-date, patched version of Office. The problem is that most users of control systems are reluctant to base operating their control systems over the Internet. EMBEDDED O P E R AT I N G SYSTEMS.

UNIX, which has been around for over 40 years, has had time to mature. UNIX vendors are far less numerous now because many have consolidated and partnered in the past few years, resulting UNIX in fewer language variants. UNIX has suffered through the years from each vendor’s lack of sufficient market share, preventing mass-marketing of their software. ______

Linux is an open-source clone of UNIX. Open-source does not necessarily mean free, only that the source code is available. In most of its distributions, Linux has a good reputation as an application server and its total cost of ownership rivals or, in some cases, betters that of Windows. While there are many good Linux programs that will do at least some of what the users want, most programming firms, which are in business to make money from programming services, do not want to give away software or intellectual property rights, as is required by some of the open-source Linux license agreements. There are a number of problems with using open source programs, particularly with concern to both financial and operational liability of an open-source industrial program. Apparently, Novell will do the open-source things while Microsoft will make Windows work better with ______—a win-win for users, if it works out. In 2011, Microsoft and SUSE, an independent business unit of The Attachmate Group Inc., announced a 4-year extension of the groundbreaking agreement struck nearly 5 years before, between Microsoft and Novell, for broad collaboration on Windows and Linux interoperability and support. This relationship will extend through 1 January 2016, with Microsoft committed to invest $100 million in new SUSE Linux Enterprise certificates for customers receiving Linux support from SUSE. Another popular release of Linux-based systems is Ubuntu, which is applicable wherever Linux computers can be used.

The TCP/IP suite offers FTP for file transfers; however, it is somewhat limited when it comes to file sharing for applications and browsers. The Common Internet File System is a variant of the SMB protocol that Microsoft proposed to the Internet Engineering Task Force as an open standard. Since Microsoft-based clients are a large number of the Internet hosts , it is highly likely that CIFS will reign and that Sun’s Network File System will be used strictly for UNIX-only answers UNTIL VERSION 5. ______
