                                       History of Operating Systems



Historically operating systems have been tightly related to the computer architecture, it is good idea to study the history of operating systems from the architecture of the computers on which they run.

Operating systems have evolved through a number of distinct phases or generations which corresponds roughly to the decades.
The 1940's - First Generations

The earliest electronic digital computers had no operating systems. Machines of the time were so primitive that programs were often entered one bit at time on rows of mechanical switches (plug boards). Programming languages were unknown (not even assembly languages). Operating systems were unheard of .
The 1950's - Second Generation

Windows XP SP3 to Include Some Vista Features A Web site that leaked details of Windows XP Service Pack 3 over the weekend claimed that the update includes several new features, including some borrowed from Windows Vista. According to NeoSmart Technologies, Windows XP SP3 build 3205, which was released to beta testers, includes four new features among the 1000-plus individual hot fixes and patches that have been issued since XP2’s debut three years ago. Features backported from Vista, said NeoSmart, include Network Access Protection (NAP), an enterprise policy enforcement technology that inspects client PCs before they access a corporate network, then updates the machines if necessary or blocks them if they don’t meet specified security criteria. Other additions range from a kernel module containing several encryption algorithms that can be accessed by third-party developers, to a new Windows activation model that doesn’t require users to enter a product key. Microsoft had previously announced SP3 support for NAP, which is part of Windows Vista and will be included in the not-yet-finalized Windows Server 2008. Windows XP SP3, which Microsoft has said will be released early in 2008, will be one more move by the developer to extend the lifespan of the six-year-old operating system. Last month, for example, Microsoft gave Windows XP a five-month reprieve by pushing back the end of retail sales and sales of XP-powered PCs by large resellers to June 30, 2008. And last week, Microsoft debuted a new “get-legal” program that lets companies purchase large quantities of Windows XP Professional licenses through their usual resellers. Microsoft was not immediately available for comment on the leak, or the new features touted by NeoSmart.
