Distributed operating system Overview: A distributed operating system is the logical aggregation of operating system software over a collection of independent, networked, communicating, and physically separate computational nodes. Individual nodes each hold a specific software subset of the global aggregate operating system. Each subset is a composite of two distinct service provisioners. The first is a ubiquitous minimal kernel, or microkernel, that directly controls that node’s hardware. Second is a higher-level collection of system management components that coordinate the node's individual and collaborative activities. These components abstract microkernel functions and support user applications. Description A distributed operating system (OS) is an operating system is a generalization of a traditional operating system. A distributed OS provides the essential services and functionality required of an OS, adding attributes and particular configurations to allow it to support add...

Web mining - is the application of data mining techniques to discover patterns from the Web . According to analysis targets, web mining can be divided into three different types, which are Web usage mining, Web content mining and Web structure mining.

Web usage mining is the process of finding out what users are looking for on the Internet . Some users might be looking at only textual data, whereas some others might be interested in multimedia data. [ edit ] Web structure mining Web structure mining is the process of using graph theory to analyze the node and connection structure of a web site. According to the type of web structural data, web structu...
