Abstract
This is a LAN Messenger designed to function in a heterogeneous network containing mainly machine running on windows-based and Linux-based machines on which the Java Virtual Machine( JVM) is running. The main reason for taking up such a project was the lack of a simple LAN Messenger which works in a heterogeneous network. The obvious choice of the programming language was JAVA in which the compiled byte codes can be interpreted on any machine running the JVM. Moreover, the product is based on a peer-to-peer architecture rather than t ....etc

virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devicesVLANs are created to provide the segmentation services traditionally provided by routers in ....etc

ABSTRACT:- In the autumn of 1969, we decided to try a new approach to the design of a virtual machine operating system. Until that time, most installations using Virtual Machine Monitors merely ran operating systems that already existed for €œstand-alon use. Few, if any, installations had attempted to design and create an operating system that took advantage of its running environment. The Virtual Machine Monitor we were using was a highly modified version of CP-67 which was designed to operate on an IBM S/360 Model ....etc

Virtual Database Technology for Distributed Database



introductionn

In a large modern enterprise, it is almost inevitable that different portions of the organization will use different database management systems to store and search their critical data. Competition, evolving technology, mergers, acquisitions, geographic distribution, and the inevitable decentralization of growth all contribute to this diversity. Yet it is only by combining the information from these system ....etc

Wireless LAN Security

Wireless local area networks (WLANs) based on the Wi-Fi (wireless fidelity) standards are one of today's fastest growing technologies in businesses, schools, and homes, for good reasons. They provide mobile access to the Internet and to enterprise networks so users can remain connected away from their desks. These networks can be up and running quickly when there is no available wired Ethernet infrastructure. They can be made to work with a minimum of effort without relying on specialized corporate installers.
