18. MS-Windows Computer Center | Network Group IISER Bhopal

19. Computer Center | Network Group IISER Bhopal Microsoft Windows Operating System Microsoft Corporation announced on November 10, 1983, in New York City, a next-generation operating system that would provide a graphical user interface (GUI) and a multitasking environment for IBM computers. The first version of GUI based operating system named as WINDOWS, introduced by Microsoft Corporation in November 1985. It has more than 85% market share of the client operating system in world. Recent version of Windows is: Windows 10 Windows Server 2008 R2 (Server OS)

20. UNIX Computer Center | Network Group IISER Bhopal

21. Computer Center | Network Group IISER Bhopal UNIX Operating System Unix is a multi-user, multi-tasking operating system. You can have many users logged into a system simultaneously, each running many programs. It's the kernel's job to keep each process and user separate and to regulate access to system hardware, including CPU, Memory, Disk and other I/O devices.

22. Computer Center | Network Group IISER Bhopal UNIX Operating System First Version was created in Bell Labs in 1969. Some of the Bell Labs programmers who had worked on this project, Ken Thompson, Dennis Ritchie, Rudd Canaday, and Doug McIlroy designed and implemented the first version of the Unix File System on a PDP-7 along with a few utilities. It was given the name UNIX by Brian Kernighan.

23. Computer Center | Network Group IISER Bhopal UNIX Operating System 1973 Unix is re-written mostly in C, a new language developed by Dennis Ritchie. Being written in this high-level language greatly decreased the effort needed to port it to new machines. 1977 There were about 500 Unix sites world-wide. 1980 BSD 4.1 (Berkeley Software Development) 1983 SunOS, BSD 4.2, System V 1988 AT&T and Sun Microsystems jointly develop System V Release 4 (SVR4). This later developed into UnixWare and Solaris 2. 1991 Linux was originated.

24. LINUX Computer Center | Network Group IISER Bhopal

25. Computer Center | Network Group IISER Bhopal LINUX Operating System Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. It originated in 1991 as a personal project of Linus Torvalds, a Finnish graduate student. The Kernel version 1.0 was released in 1994 and today the most recent stable version is 2.6.9 Developed under the GNU General Public License, the sourceGNU General Public License code for Linux is freely available to everyone.

28. Computer Center | Network Group IISER Bhopal Apple - MAC Operating System A first GUI base operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. Apple would later name the "Mac OS“ first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

29. Client Server Architecture About Computer Center | Network Group IISER Bhopal

30. Computer Center | Network Group IISER Bhopal Client/Server Architecture Client - Requester/Application/System Eg: Desktops/Laptop/Smart Phones/Workstation That can access some services hosted on remote location by using network resources. Small in SIZE. Use at a single location. Portable computers such as Laptop. Powerful than PC in terms of Processing, Memory, Graphics. Designed for technical and scientific applications.

31. Computer Center | Network Group IISER Bhopal Client/Server Architecture Server – Powerful Machine or Clusters Eg: Who serves the request. That provides essential services to clients/other computer programs and their users. Group of linked computers. Working together like a Single Computer. Commonly used for HPC (High Performance Computing), HA (High Availability), Load Balancing.

32. Computer Center | Network Group IISER Bhopal Client/Server Architecture Servers commonly contain data files and applications that can be accessed across the network, by workstations or employee computers. An employee who wants to access company-wide data files, for instance, would use his or her client computer to access the data files on the server. Other employees may use a common-access application by accessing the server through their client computers. Server is not just for storage, however we can use it for HPC (High Performance Computing).
