Web Search Engines Seminar For Students is a program that is designed to locate stored data on the World Wide Web (WWW). Search engine indexes are complex and similar. The quality of the indexes breaks or makes the quality of search results.

The large number of users navigates the Web via search engines. It is more likely to display thousands of responses by typing a keyword or phrase and a handful are near to what we searching are located on secondary search pages. A web search engine helps a person to retrieve a number of references that match the content.

The first Web search engine was “Wandex”, collected by the World Wide Web Wanderer and other early search engine is Aliweb and the first “full text” crawler-based search engine was WebCrawler.

 The steps which are involved in processing search engine are Document Gathering-done by Crawlers, spiders, Document Indexing-done by Indexer, Searching, and Visualisation of results. The most emerging technologies in today’s network are Google, yahoo, MSN etc.

 The few challenges include that the web is growing faster than present technology search engine can possibly index, search engine has to revisit periodically, generated sites can be slow or difficult to index, sites are not indexable by search engines and this phenomenon is called invisible web, sites make use of tricks to manipulate the search engine to display them as the first result returned for some keywords. This may lead to search results being polluted.

Conclusion:

The usage of a search engine depends on the relevance of the results it gives back. The methods of search change from time to time as Internet usage changes with new techniques evolve. Most search engines help methods to grade the results to provide the “best” results first. There are other types of search engine that enterprise search engines that search on intranets, personal search engines that search individual personal computers, and mobile search engines.

Voice over Internet Protocol Internet Phone Seminar is the voice delivered by the internet protocol. This is a term used in IP telephony to manage the delivery of voice information with the help of internet Protocol (IP). It is best known as talking PC to PC. Therefore, VoIP is telephony that is using a packet based network instead of PSTN (circuit switched).

Voice over IP is the technology of digitizing sound, compressing it, breaking it up into data packets, and sending it over an IP (internet protocol) network. It is reassembled, decompressed, and converted back into an analog wave form. This technology is transparent to the user and requires minimum training. It is a single cable infrastructure.

The major advantage of VoIP and Internet telephony is it reduces the call charges by ordinary telephone service. The main concept was to compress the voice signal and translate into IP packets for transmission on the Internet. Vocal Tec’s Internet phone was a significant breakthrough. The significant development is gateways which act as an interface between IP and PSTN networks.

 Voice over IP (VoIP) is a blanket description for any service. It delivers standard voice telephone services over Internet Protocol (IP). Computer transfers data and files between computers normally with the help of Internet protocol.

Within a packet switched network, digital data is broken down into packets, sent over the network, and reassembled at the destination. This circuit can accommodate various transmissions at a time. Gateways are required to facilitate IP Telephony. A gateway is provided to bridge the circuit switched PSTN with the packet switched Internet.

Conclusion:

Based on packetized technology, vendors of voice equipment may continue to progress integrated voice and data devices. With the help of ubiquitous voice and data service, users are integrated over universal infrastructure and will have transparent, true, and seamless, internetworking between voice and all types of data.

Virtual Reality Paper Presentation is a complex user interface. It includes simulations in real time with multiple sensory channels. These sensorial modalities are visual, auditory, tactile, olfactory, etc.” VR is the penultimate of human computer interaction (HCI). It helps a person to participate in a three-dimensional computer-simulated world. Users of VR refer to their experience as “getting into” or becoming immersed in the virtual world. Movement of the head or body gives a resultant change in today’s computer generated world.

 VR is immersive with the help of special devices and the user gets the sense of being physically within the virtual world. The virtual world is scaled to the real world, human proportions, auditory, haptic and non-visual technologies which reinforce presence in simulated environments. Data devices provide access and alteration of the virtual world that make VR interactive. The participant is not a passive observer and interacts in a virtual world which will alter according to actions.

 Users wear a head-mounted display (HMD) which consists of a computer screen in front of the user’s eyes and a head tracking device. Head-orientation and location information is monitored which is relayed to a computer and relays the user HMD images. It relates to the direction where the user is looking in the virtual environment. Virtual scenes are constructed by integrating video images of real people with effects generated by programs such as 3D Studio MAX and DeepPaint.

 Virtual Reality is utilized to describe a generated computer virtual environment that is moved in real time and this environment is placed on a head-mounted display or a computer monitor, or a large projection screen.

 Conclusion:

 Within a short time, Virtual Reality has lost image of a technology and it is applied to every field of human life. VR provides better approach to understand the work and can be used in various fields like military and surgery, which is possible by Simulators.

Java 3d API is selected as software tool for developing interactive FEA.

It is possible to develop a virtual environment display for research and rehabilitation of balance disorders called Balance NAVE (BNAVE). It is a promising tool for rehabilitation. It has four PC’s, three stereoscopic projectors, and the three rear- projected screens. Virtual reality is used in many fields like Entertainment, Education, Science, Medical, Defense etc.

Virtual Reality (VR) is popular name for an absorbing, interactive, Computer-mediated experience where a person perceives a synthetic (simulated) environment with the help of special human-computer interface equipment. It interacts with simulated objects as if they were real.

 Virtual Reality is used to describe a computer generated virtual environment which may be moved in real time. This environment is displayed on a head-mounted display, a computer monitor, or a large projection screen. Head and hand tracking systems enable the user to observe, move around, and manipulate the virtual environment.

There are four technologies are crucial for VR. They are the visual displays that immerse the user in virtual world, the graphics rendering system that generates at, 20 or 30 frames per second, the tracking system that reports the position of user’s head and limbs, and the database construction and maintenance system for building design. Basically, there are three types of Virtual reality systems. They are fully immersion system, semi-immersion, and non-immersion.

Conclusion:

Within a short span of time, Virtual Reality has lost image of a technology for a problem and is applied to nearly every field of human life. In FEA, VR provides better approach for understanding the work. It is used in many fields like military and surgery, and it is possible by Simulators.

Virtual private network (VPN) Seminar offers secure, low-cost, and dynamic access to private networks. It allows remote users to access securely private networks across the Internet. With the help of VPN, a remote user can establish a secure network connection in the whole world.                 

We are familiar with VPN issues like security, firewalls, and routing/switching. A virtual private network provides secure access to LAN resources over network such as internet. It is conceptualized as the creation of a tunnel from one location to another considering as an Encrypted data passing in a tunnel before getting decrypted at its destination.

A user uses 56 kilobits per second (Kbps) modem to dial their internet service provider (ISP) and connects to the central LAN with VPN software. A remote site uses ADSL (asymmetric digital subscriber line) to connect to its ISP and a VPN router (a hardware solution) to carry out the VPN connection.

Virtual refers to the connection which is dynamic. It can be changed and adapted to different circumstances by making use of internet’s fault tolerant capabilities. Private means transmitted data is kept confidential and is accessed by authorized users. Network is the whole infrastructure between the endpoints of users, sites or nodes which carries the data.

There are variations of virtual private networks. They are Remote access (Virtual private dial-up network (VPDN) or client-to-site) and Fixed (Intranet and extranet or site-to-site). As VPN topologies varies greatly so there is no standard for a definitive VPN. VPN gateways create the virtual tunnels by which the data passes through and gateways can be software, firewall, a server, or router or a dedicated appliance.

Conclusion:

VPN is the best technology for the corporate networking. It provides best combination of security and private network capabilities with adequate cost. Various tools are available to manage WAN links. These range from Quality of Service tools for traffic classification, Policing/Shaping, Bandwidth Allocation, and Congestion Avoidance.

Virtual Firewall System (VFS) can be standalone or installed as an integrated Gateway solution. On a corporate Security Policy, a firewall is configured for security based. A security policy consists of security strategy for information technology. A Virtual Firewall System (VFS) has multiple logical firewalls which are geographically distributed on a system. Like firewalls, Virtual Firewalls gives easy management of a many number of firewalls by security policies at defined security domains.

 The main advantages of Virtual Firewalls are ease of deployment and management and also reduced costs. It offers scalability and can define “security domains” or boundaries for firewalls over a network. It greatly reduces cost and resources to manage the system.

 A firewall is a device between networks to separate and protect the privacy and integrity of business communications and provides network security. It safeguards against malicious use. It is positioned between a corporate private network (trusted network) and other public networks. It monitors and enforces corporate policies flowing in and out of the corporate network.

 Conventional firewalls have basic function for controlling access to communication between an enterprise network and the outside world. Therefore the next generation firewalls may significantly have increased security capabilities. It prevents Denial-of-service (DoS) and Distributed DoS attacks.

 Standard features of firewalls include protection against various DOS and DDOS attacks, Policy-based access control, Inbound and Outbound policies for the corporate network, Separate set of policies for DMZ network(s), Access control, Application content filtering, Generation of log and alert messages, Generation of access statistics, and Intuitive user interface.

Conclusion:

With the increase dependence and dominance of the Internet, it is really necessary to have secured communication channels. It has a great market opportunity for scalable security solutions. A firewall is a network security device positioned between networks to logically separate and protect the privacy and integrity of business communications over the networks. It safeguards against malicious use.
