There are many social networking sites available. Most of the people are using internet for entertaining purposes, collect information and online shopping. It is used to transmit lot of data within a second. The data communication is used to transmit data between two various locations. It is connected through electromagnetic medium. You can get lot of information with the use of internet. It is the most cost effective communication. It provides many services such as digital marketing, content management systems, mobile solutions design, online games, discussion forums, real time chat, intranet application development, website, portal design, shopping cart applications, social media integration, localization services and many more. It is used in many business fields.

An optical computer is made with photons or light particles. It is application specific devices. It is designed with the principles of optical computing. The best example of optical computing is optical correlators. It is used for tracking and detecting objects. The main component of optical computer is the transistor. It is used to make optical logic gates. The optical computer is also known as a photonic computer. It is faster compared to conventional electronic computer. It is a hypothetical device. It uses infrared beams. It means operations, storage, transmission of data and performing computations. It has many internal circuits. Light is a source of computing. The first optical transistors were introduced in the year of 1980. The optical computers consist of transistors and semiconductors. It is used to control electricity and it is used to analyze the crystals and metamaterials. In this system, the electrons are replaced by photons. It is more traditional and faster than copper wires.

In these days, cellular communication is more popular. It is an electronic device. The mobile phone is also known as cellular phone. It is used to make and receive calls from any kind of phones, send messages and entertaining purposes. But modern mobile phones are made with an advanced technology such as text messaging, MMS, internet access, email, Bluetooth facility, photography, gaming, business applications and many more. The first mobile phone was introduced by Dr Martin Cooper in 1973 of Motorola. The cellular communication is made with lot of low power wireless transmitters. The mobile phones provide many features. It consists of many components such as a battery, a keypad, sim card and International mobile equipment identity number but touch screens have no keypads. In these days, one of the main purposes of mobile phones is SMS text messaging. These mobile phones get power from rechargeable batteries. The battery is in small size and low weight.

Intrusion deduction system is one kind of software application. Intrusion detection and prevention systems are used to find the incidents, reporting attempts and logging information. It provides many purposes such as documenting existing threats, finding problems with security policies and deterring individuals. It records the information oriented to notify security administrators, observed events, produce reports and many more. There are many types of intrusion detection systems available such as network intrusion detection system and host- based intrusion detection system. The first type is used to gain network traffic to network switch, network hub and port mirroring or network tap. The second type of host based intrusion detection system contains file- system modification, analyzing system calls, application logs and many host activities. It is used to detect the security breach, logs and signals. It is also known as reactive systems or intrusion prevention system. It is used to identify the outbound and inbound network activity.

Quantum cryptography explains about the use of quantum mechanical effects. It is the combination of the quantum communication and quantum computation. It provides many advantages. It includes various types of cryptography tasks. The best quantum cryptography is quantum key distribution. This process is used for quantum communication and used to share key between two parties. Quantum key distribution provides secure and guarantee communication. It includes the group of quantum cryptographic tasks. The main purpose of the quantum cryptography is used to find the geographical location. Quantum key distribution does not use to transmit any kind of message data. It is used only to choose encryption algorithm to encrypt a message. It is one kind of art of encoding and decoding messages. It is used to secure communication. It is used to transfer information to the recipient. It is based on the encrypting and decrypting procedures. Quantum key distribution is the best example of quantum cryptography.

Voice portals are one of the parts of web portals. It is used to access information over the voice responses and spoken commands. It provides many functions such as type of information, services or transactions. It is called as interactive voice response systems. It includes DTMF services. There are many web companies provide voice- based access to internet information to their customers. Sometimes, it is called a vortal. It includes voice portal interacting such as speech recognition, audible speech or telephone keypad interface. It is provided by a different source such as flat file, multidimensional data bases and web page content. It has two categories such as an enterprise voice portal and a consumer voice portal. The first kind of enterprise voice portals are used to control inbound and outbound voice traffic. It is growing technology. It works based on a short code and users pay per minute of usage.

Light tree is implemented in the concept of wavelength routed optical network. It is based on the physical topology networks. It has three generations. The first generation includes fiber optic technology, the second generation include optical fibers and the third generation is used for both data transmission and switching purposes. The technology of fiber optic is used to microwave technology. Optical fibers are used for data transmission. It is operated with wavelength- division multiplexing. It is used to filer nodes and electronic switches. It is used with routing nodes. It is used to transmit signals in various wavelengths. It is based on an optimum light- tree virtual topology. It provides many advantages. It is used to improve traffic performance. It increases the legal connectivity of the network and decreases the distance. It is used to minimize the network wide average and minimize the total number of transceivers in the network.

Dashboard is one kind of interface. It is like an automobile’s dashboard. It is used to organize information and provide easy to read. It is designed with the most graphical user interfaces. It is desktop based application. It comes in three various packages such as desktop edition, excel edition, enterprise edition. Each type is used for specific purposes. The excel edition is used to store data in excel files. The desktop edition is used for individual use and the enterprise edition is used for many functions through a group server. The enterprise edition includes many functions such as multiple data sources, relative date formatting, and drill down, KPI indicators, export and share. The Java script charting is used to make dashboards. It is the most associated with Google services such as your name, the number of contacts, your email addresses, your Google profile, the number of conversations and your Gmail inbox.
