ABSTRACT: The World Wide Web (WWW), a web of worldwide servers connected to the Internet, provides an easily used and understood method of accessing electronic content. Accessing information requires data communication between a Web-browser client and a Web-server application. Web hosting, then, is a means of hosting the Web-server application on a computer system through which electronic content on the Internet is readily available to any Web-browser client. The basic concept of Web hosting on a dedicated computer system consists of hosting one Web site on one computer system. The dedicated environment offers complete flexibility and security to both the WPP and the customer. Web hosting on a dedicated computer system is the simplest and most straightforward method of operating a Web site. The basic concept of Web hosting on a shared computer environment consists of hosting many different Web sites on one computer system. The shared environment offers economic benefits to both the WPP and the customer. web-hosting

ABSTRACT: WAP – The Wireless Application Protocol – is a communications protocol and application environment for the deployment of information resources, advanced telephony services, and Internet access from mobile devices. The topic that I have chose is the WAP Application Architecture and the main concern here will be –WAP Client WAP Proxy, WAP Gateway Or WAP Server WAP Application Server WAP Internal Structure WAP Protocol Stack The WAP Protocols were designed with the web protocols in mind. The goal of WAP was to use the underlying web structure, but to render communication between content providers and mobile devices more efficient and less time consuming than if the web protocols themselves were used. I will be introducing the elements involved in mobile communications, and their role in the whole picture.wap-the-wireless-application-protocol
ABSTRACT:Voice Security Systems is responsible for an innovative method of security that dramatically reduces fraud and can insure ones property from use, if stolen, or obtained fraudulently. Voice security uses a biometric technology.Taken from the Greek ‘Bio’ meaning life, and ‘Metric’ the measure of, Biometrics is the measure (study) of life. Humans, plants and animals.Voice Security Systems Inc. was formed in 2000 to research and develop a user-friendly voice authentication technology. This concept originated in an idea for a voice controlled garage-door opener. The technology of using voice prints for authentication was in its infancy, requiring expensive DSP processors and large storage requirements for the software and voice template storage.Voice Security Systems Inc. invented a process that utilizes the self-contained, microprocessor based access control technology. This technology is used to activate electronic devices, doors, etc. using a voice command that will ONLY work for the authenticated individual. This technology is referred to as PowerVoice™ technology.voice-security-system
ABSTRACT:Voice and data transmission are fundamental aspects of the information age we live in. Yet until recently we have relied on very different networks to deliver voice and data. As a result, the ways in which we interact with these networks are far from seamless. Voice over IP Packet (VoIP) is just beginning to deliver on the promise of integrated voice and data services. This convergence of services will allow us to work more efficiently and powerfully than ever before.Voice over IP (VoIP) networks are integrated multi-service networks that carry both voice and data. This report focusses on understanding the requirements and architecture of VoIP networks and explains some of the issues involved in maintaining good voice quality. The Bottomline being that a voice over packet application meets the challenges of combining legacy voice networks and packet networks by allowing both voice and signaling information to be transported over the packet network.voice-over-ip-packet-voip
Abstract: Virtual Local Area Network (VLAN) is a group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. It is a group of PCs, servers and other network resources that behave as if they were connected to a single, network segment — even though they may not be. For example, all marketing personnel may be spread throughout a building. Yet if they are all assigned to a single VLAN, they can share resources and bandwidth as if they were connected to the same segment. The resources of other departments can be invisible to the marketing VLAN members.VLAN allow highly flexible, efficient network segmentation, enabling users and resources to be grouped logically, without regard to physical location. This type of networking helps in providing security to a particular workgroup and can also be easily managed.VLAN offer an effective solution to swamped routers and broadcast storms. By limiting the distribution of broadcast, multicast and unicast traffic, they can help free up bandwidth, reduce the need for expensive and complicated routing between switched networks, and eliminate the danger of broadcast storms. With these advantages, VLAN revive many of the key advantages of LAN routing, but with greater flexibility, performance, simplicity and affordability.virtual-local-area-network
Introduction: In today’s information age, there are a multitude of ways to communicate with others including voice, fax, and email. The combined or rather unified use of these messages gives a way of unified messaging. The basic idea behind unified messaging is a simple one. Rather than having separate viewers or procedures for voice mail, e-mail and fax messages, it would be far simpler to put them all into a single integrated inbox. Then click on E-mail message, it gets displayed in e-mail editor, click on fax message, it gets displayed in a fax viewer for printing, click on voice mail message it is played on a PC speaker.unified-messaging
Abstract :- TCP/IP fingerprinting is the process of determining the identity of remote host OS by analyzing packets from the host. The seminar gives an idea about TCP/IP fingerprinting,reasons for fingerprinting, classical techniques of detecting remote OS, different types of fingerprinting, techniques used to fingerprint stacks, fingerprinting via NMAP (a tool for performing active TCP/IP fingerprinting) and finally describes a technique for defeating this.tcpip-fingerprinting
Advances in computing technology , compression technology , high bandwidth storage devices and high-speed networks have made it feasible to provide real-time multimedia services over the network .Real-time multimedia has timing constraints ,for example audio and video data must be simultaneously played out . Otherwise process will pause. Real-time transport of live video or stored video is the predominant part of real-time multimedia . In this we are concerned with video streaming which refers to real-time stored video . There are two modes of transmission of stored video namely , Download mode and Streaming mode(video streaming) . In case of download mode the entire video is downloaded first and then plays back the video file . In case of streaming mode streaming mode ,the video content is need not be downloaded in full , but is played out while parts of the content are being received and decoded . Due to the real-time nature the video streaming typically has band-width, delay and loss requirements .It is difficult to meet the wide range of QoS requirements from users . Thus the designing mechanisms and protocols for Internet streaming video poses many challenges .streaming-video-over-internet
Abstract:SCTP (Stream Control Transmission Protocol) is an extended version of TCP/IP approved by Internet Engineering Task Force as a proposed standard in October 2000. SCTP was spawned from an effort started in the IETF Signaling Transport (Sigtrans) working group to develop a specialized transport protocol for call control signaling in Voice-over-IP (VoIP) networks. Recognizing that other applications could use some of the new protocol’s capabilities, the IETF now embraces SCTP as a general purpose transport layer protocol, joining TCP and UDP above the IP layer.
This paper starts with the description of architectural view of SCTP followed by the features of SCTP. The paper also covers the description of SCTP packets and the functional view of SCTP in detail.The paper also covers the deployment aspects of SCTP and its impact on signaling area. The paper concludes with a look at the future issues of SCTP. stream-control-transmission-protocol
ABSTRACT:A major issue of concern in the study of digital communications has been that of providing for the efficient utilization of bandwidth and power. Bandwidth and power are the two primary communication resources, and it is therefore essential that they are used with care in the design of most communication systems. The system may be required to provide a form of secure communication in a hostile environment such that the transmitted signal is not easily detected or recognized by unwanted listeners. This requirement is catered to by a class of signaling techniques known collectively as spread-spectrum modulation.The primary advantage of spread-spectrum communication system is its ability to reject interference whether it be unintentional interference of another user simultaneously attempting to transmit through the channel, or the intentional interference of a hostile transmitter attempting to jam the transmission.spread-spectrum-systems
