There is now an identifiable trend in industry toward downsizing that is replacing expensive mainframe computers with more cost-effective networks of personal computer that achieve the same or even better results. This trend has given rise to the architecture of the Client/Server Computing. The term Client/Server was first used in the 1980s in reference to personal computers on a network. The actual Client/Server model started gaining acceptance in the late 1980s. The term Client/Server is used to describe a computing model for the development of computerized systems. This model is based on the distribution of functions between two types of independent and autonomous entities: Server and Client. A Client is any process that request specific services from server processes. A Server is process that provides requested services for Clients. Or in other words, we can say “A client is defined as a requester of services and a server is defined as the provider of services.”...

Microsoft is a multibillion dollar organization and without them we would not be where we are today in the world of computers and technology. They have Cloud Computing, Bing search engine, and even Microsoft Dynamics, Lync systems, and even windows server which is used by IT specialists to increase the reliability of their server infrastructures. Each of these services is separately installed and you can buy them real cheap off their website at http://www.microsoft.com/government/ww/safety-defense/products/Pages/index.aspx. I chose Windows 8 because I am currently using it on my computer and I wanted to learn more about this specific operating system. I chose Ubuntu as my choice for Linux distributor because it was number one on the list and the first one I saw and I like the name. The name Ubuntu comes from African culture and it means “I am what I am because of who we all are”. Ubuntu on the other hand comes from...

...CLIENT SERVER PROGRAMMING AND MULTIMEDIA Introduction Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request. Although the client/server idea can be used by programs within a single computer, it is a more important idea in a network. In a network, the client/server model provides a convenient way to interconnect programs that are distributed efficiently across different locations. Computer transactions using the client/server model are very common. For example, to check your bank account from your computer, a client program in your computer forwards your request to a server program at the bank. That program may in turn forward the request to its own client program that sends a request to a database server at another bank computer to retrieve your account balance. The balance is returned back to the bank data client, which in turn serves it back to the client in your personal computer, which displays the information for you. The client/server model has become one of the central ideas of network computing. Most business applications being written today use the client/server model. So does the Internet's main program, TCP/IP. In marketing, the term has been used to distinguish distributed computing by smaller dispersed computers from the "monolithic" centralized computing of mainframe computers. But this distinction has largely disappeared...

...COMPARATIVE OPERATING SYSTEMS TERM PAPER SUMMER 2001 COMPARISON OF NETWORK OPERATING SYSTEMS BY MUKUNDAN SRIDHARAN COMPARISON OF NETWORK OPERATING SYSTEM S Abstract We are in a era of computing in which networking and distributed computing is the norm and not a exception. The ability of a operating system to support networking has become crucial for its survival in the market. In today’s picture there is no operating system, which doesn’t support networking. This paper tries to give a review of various network operating systems or the networking support of a operating system, in relevance to the modern operating systems. The emphasis is on basic design and architecture, not their specifications or services. The paper considers various operating systems like Novell Netware, the sun NFS, the Styx, CIFS/SMB and Microsoft Windows 2000 server. Again the concentration is on modern and evolving operating systems like the Novell Netware and Microsoft’s Windows 2000. The objective of the paper is to study and compare various operating systems and to bring out the inherent advantages and disadvantages in using them. 1.0 INTRODUCTION Individual computers are connected together to form computer networks. The operating system, protocols and services which help us in interconnecting the computers are collectively called Network Operating systems. The webopedia.com defines Network Operating Systems as follows: An operating system that includes...

... CONTENTS 1. INTRODUCTION TO VIRTUALIZATION 2. TYPES OF VIRTUALIZATION 3. ADVANTAGES OF VIRTUALIZATION 4. VIRTUALIZATION IN INDIA 5. REFERENCES INTRODUCTION Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. In layman's term, virtualization allows you to run an independent operating system within an existing operating system using the existing hardware resources. So if you want to learn another operating system like Linux, you can use virtualization to run Linux on top of the existing operating system. Virtualization is the abstraction of IT resources, separating their physical instance and boundaries from their function. Virtualization has brought important innovation to IT Virtualization concept was first developed by IBM in the 1960s to fully utilize mainframe hardware by logically partitioning them into virtual machines. These partitions will allow mainframe computers to perform multiple tasks and applications at the same time.. During the 1980s and 1990s, desktop computing and x86 servers become available and so the virtualization technology was discarded eventually. Client-server applications and the emergence of Windows and Linux made server computing significantly inexpensive. However, new challenges has surfaced which includes high maintenance...
