TAILIEUCHUNG - Lecture Introduction to computing - Lecture 17

This lesson introduces you to some of the most commonly used types of application software the programs that millions of people use each day to accomplish routine tasks. Although you might think of a computer as being a highly specialized machine, in fact it is most often used for basic, everyday tasks at home, school, and work. By applying computers and application programs to these mundane tasks, people can be more productive, creative, and efficient. | CSC 101 Introduction to Computing Lecture 17 Dr. Iftikhar Azim Niaz ianiaz@ 1 1 Last Lecture Summary System software Operating systems Functions of Operating System Start and Shut down Providing a User Interface Managing programs Managing memory Coordinated tasks and Configure devices Internet connections, Monitor Performance Providing Utilities and automatic Update Control a network and Administrator Security 2 2 Operating System Evolution Over past 30 years, the evolution in OS has made PCs easier to use and understand more flexible and more reliable Many of the first operating systems were device dependent and proprietary A device-dependent program is one that runs only on a specific type or make of computer Proprietary software is privately owned and limited to a specific vendor or computer model Some OS still are device dependent Operating System Evolution A device-independent OS is one that run on computers provided by a variety of manufacturers Advantage is you can retain existing application soft ware and data files even if you change computer models or vendors As new versions of the OS are released, users upgrade their existing computers and mobile devices to incorporate features of the new version Purchasing an OS upgrade usually costs less than purchasing the entire operating system New versions of OS usually are backward compatible Application software, by contrast, may or may not be upward compatible, meaning it may or may not run on new versions of the operating system Types of Operating Systems Windows Version Year Released Windows 1990 Windows NT 1993 Windows 95 1995 Windows NT Workstation 1996 Windows 98 1998 Windows Millennium Edition 2000 Windows 2000 Professional 2000 Windows XP 2001 Windows XP SP2 2004 Stand Alone Operating Systems Stand-alone OS is a complete OS that works on a desktop computer, notebook computer, or mobile computing device. Some stand-alone OS are called Client OS because they also work in .
