Client-side scripts are often embedded within an HTML or XHTML document (hence known as an “embedded script”)‚ but they may also be contained in a separate file‚ to which the document

Distributed File System Abstract A method of storing and accessing files based in a Client/Server Architecture. In a distributed file system‚ one or more central servers store files that can be accessed‚ with proper authorization rights‚ by any number of remote clients in the network. Much like an operating system organizes files in a hierarchical file management system‚ the distributed system uses a uniform naming convention and a mapping scheme to keep track of where files are located.

The client–server model is an approach to computer network programming developed at Xerox PARC during the 1970s. It is now prevalent in computer networks. Email‚ the World Wide Web‚ and network printing all apply the client–server model. The model assigns one of two roles to the computers in a network: Client or server. A server is a computer system that selectively shares its resources; a client is a computer or computer program that initiates contact with a server in order to make use of a resource

Introduction about Linux Linux is an operating system that was initially created as a hobby by a young student‚ Linus Torvalds‚ at the University of Helsinki in Finland. Linus had an interest in Minix‚ a small UNIX system‚ and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. Linux is developed and released under the GNU General Public License and

Limitations of Primary Memory: Limited capacity because the cost per bit of storage is high Volatile - data stored in it is lost when the electric power is turned off or interrupted. So as a result additional memory called auxiliary memory or secondary memory is used. Following are the features of Auxiliary or Secondary Storage: 1. Permanent or Non-volatile Storage: The data which is stored in those devices is not lost when the power is switched off. The data is retained. 2. Voluminous

A vacuole is a membrane-bound organelle which is present in all plant and fungal cells and some protist‚ animal[1] and bacterial cells.[2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution‚ though in certain cases they may contain solids which have been engulfed. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.[3] The organelle has no basic

In Computer science client-server is a software architecture model consisting of two parts‚ client systems and server systems‚ both communicate over acomputer network or on the same computer. A client-server application is a distributed system consisting of both client and server software. The clientprocess always initiates a connection to the server‚ while the server process always waits for requests from any client. When both the client process and server process are running on the same computer
