1PAGE OPERATING SYSTEMS AND SYSTEMS PROGRAMMING -BY 3RD YEAR CP-2 BEARING PIN FROM 219 TO 225
2PAGE Anoperating systemis themost important softwarethat runs on a computer. It manages the computer'smemoryandprocesses, as well as all of itssoftwareandhardware. It also allows you tocommunicatewith the computer without knowing how to speak the computer's language.Without an operating system, a computer is useless. Your computer'soperating system(OS) manages all of thesoftwareandhardwareon the computer. Most of the time, there are several different computer programs running at the same time, and they all WHAT ARE OPERATING SYSTEMS ?
3PAGE Operating systems usually comepre-loadedon any computer you buy. Most people use the operating system that comes with their computer, but it's possible to upgrade or even change operating systems. The three most common operating systems for personal computers areMicrosoft Windows,Mac OS X, andLinux. Modern operating systems use agraphical user interface, orGUI(pronouncedgooey). A GUI lets you use your mouse to clickicons,buttons, andmenus, and everything is clearly displayed on the screen using a combination TYPES OF OPERATING SYSTEMS
4PAGE Microsoft created theWindowsoperating system in the mid- 1980s. Over the years, there have been many different versions of Windows, but the most recent ones areWindows 10(released in 2015),Windows 8(2012),Windows 7(2009), andWindows Vista(2007). Windows comespre-loadedon most new PCs, which helps to make it themost popular operating systemin the world. TheWindows directoryis the directory that contains Windows-based applications, initialization files, and help files. The GetWindowsDirectoryfunction retrieves the path to this directory. Thesystem directoryis the directory that contains dynamic-link libraries, drivers, and font files. MICROSOFT WINDOWS
5PAGE Mac OSis a line of operating systems created by Apple. It comes preloaded on all new Macintosh computers, or Macs. All of the recent versions are known asOS X(pronounced O-S Ten), and the specific versions includeEl Capitan(released in 2015),Yosemite(2014),Mavericks(2013),Mountain Lion(2012), andLion(2011). According toStatCounter Global Stats, Mac OS X users account for less than10%of global operating systems MAC OS X
6PAGE Linux(pronouncedLINN-ux) is a family ofopen-sourceoperating systems, which means they can be modified and distributed by anyone around the world. This is different fromproprietary softwarelike Windows, which can only be modified by the company that owns it. The advantages of Linux are that it isfree, and there are many differentdistributionsor versions you can choose from. According toStatCounter Global Stats, Linux users LINUX

8PAGE WHAT IS SPOOLING ? Simultaneous peripheral operation online N G L I O O S P
9PAGE SPOOLING IN OPERATING SYSTEMS Simultaneous peripheral operation online (Spooling). A spool is a kind ofbufferthat holds thejobsfor a device till the device is ready to accept the job. Spooling considersdiskas a hugebufferthat can store as many jobs for the device till the output devices are ready to accept them. In spooling, I/O of one job is overlapped with the computation of another job. For example, a spooler at a time may read input of one job, and at the same time, it may also print the output of another job. Spooling can also process
10PAGE SPOOLING Spooling in the operating systems acts as a process where the data temporary becomes available by holding it and then used and executed by either a device, system or a program by the help of request for executions. Spooling is an acronym for concurrent fringe operations on the line. Spooling alludes to putting information of different I/O employments in support. This cushion is a unique range of memory or hard plate which is available to I/O gadgets. Spooling works like a run of the mill ask for line or spool where information, guidelines, and procedures from different sources are amassed for execution later on. For the most part, the reel is kept up on the PCs physical memory, supports or the
11PAGE WHAT IS BUFFERING ? BUFFERING IN G E R F F B U
12PAGE BUFFERING IN OPERATING SYSTEMS Before discussing buffering, let us discuss, what is the buffer? Thebufferis an area in themain memorythat is used to store or hold the datatemporarily that is being transmitted either between two devices or between a device or an application. In simple words, buffer temporarily stores data that is being transmitted from one place to another. The act of storing data temporarily in the buffer is called buffering. There are three reasons behind buffering of data,first is it helps inmatching speedbetween two devices, between which the data is transmitted. For example, a hard disk has to store the file received from the modem. Now, as we know the transmission speed of a modem is slow, as compared to the hard disk. So bytes coming from the modem is accumulated in the buffer space, and when all the bytes of a file has
13PAGE BUFFERING Buffering in the operating system acts as a process where the specified region exists that holds all the data on a temporary basis and helps it to move from one location to the other. The buffer enables every gadget or procedure to work without being held up by the other. All together for a frame to be compelling, the span of the buffer and the calculations for moving information into and out of the support should be considered by the cradle originator. As a reserve, a buffer is a midpoint holding place yet exists less to quicken the speed of a movement as to bolster the coordination of independent exercises. Watching the video on YouTube accompanies the desire that
14PAGE WHAT ARE THE DIFFERENCES BETWEEN SPOOLING AND BUFFERING
15PAGE Spooling in the operating systems acts as a process where the data temporary becomes available by holding it and then used and executed by either a device, system or a program with the help of request for executions. On the other hand, Buffering in the operating system acts as a process where the specified region exists that holds all the data on a temporary basis and helps it to move from one location to the other. The basic operation of spooling is the overlapping of the input and output of one task with the calculation of the other task. On the other hand, the primary process of buffering becomes the overlapping of comments and output of one function with the count of the same task. Simultaneous peripheral operation online becomes another name used for spooling, on the other hand, buffering does not have any other name. The efficiency of spooling has much more relevance than the ability to buffer, on the other hand, buffering KEY DIFFEREN CES
16PAGE FFERENCES BETWEEN SPOOLING AND BUFFERI BASIS FOR COMPARISON SPOOLING BUFFERING Definition A process where the data temporary becomes available by holding it and then used and executed by either a device, system or a program by the help of request for executions. A process where the specified region exists that holds all the data on a temporary basis and helps it to move from one location to the other. Basic Spooling overlap the I/O of one job with the computation of another job. Buffer overlaps the I/O of one job with the computation of the same job.
17PAGE CONCLUSION Spooling and buffering both increases the efficiency of the computer but Spooling is better than buffering as it handles the processing of two jobs at a time.
