Well, here we are with our pervasive communication.  There's the Internet.  There's cell phones in every ear as you walk down the street or ride on the bus.  There's TV in all its forms.  There are more books, magazines, newspapers and other print materials than ever before.  Ever since we've gotten word processing and ink jet printers, and photocopiers, there have been more flyers, posters, advertising handouts and other privately printed materials than ever before.  Then there are movies, DVDs, CDs and all the more esoteric forms of communication disguised as and doing business as entertainment.\n\nWe are in an information age, which means an information overload age.  Everyone I know has at least one phone number, probably two or three (home, office and cell).  Almost everyone I know has one or more email addresses.  They have their own web pages, or at least their own blog pages, like Yahoo! 360.  There are more types of communications that go through the Internet than I've even had a chance to explore yet.\n\nYes; pervasive is definitely the word.

Yes\n\nanalogue is the old wave technology, digital is the new bit technology.\n\nNetwork Topologies are how networks are set up. It is their construction or makeup.

Definitions of Communications media on the Web:\n\nThe nature of the communications medium has a direct impact on the extent and quality of dialogue between instructors and learners. Learning in a one-way television programme, for example, students can make internal (silent) responses only. Correspondence by mail allows two-way interaction - even slow and less spontaneous, but perhaps more thoughtful and reflective. The interactive nature of the medium is the major determinant of dialogue in the teaching-learning environment. ...\nhttp://www.google.com/search?hl=en&lr=&defl=en&q=define:Communications+media&sa=X&oi=glossary_definition&ct=title\nhttp://education.qld.gov.au/corporate/newbasics/html/curric-org/comm.html

"Pervasive computing is the trend towards increasingly ubiquitous (another name for the movement is ubiquitous computing), connected computing devices in the environment, a trend being brought about by a convergence of advanced electronic - and particularly, wireless - technologies and the Internet. Pervasive computing devices are not personal computers as we tend to think of them, but very tiny - even invisible - devices, either mobile or embedded in almost any type of object imaginable, including cars, tools, appliances, clothing and various consumer goods - all communicating through increasingly interconnected networks."

communications\nThe electronic transfer of information from one location to another. "Data communications" or "datacom" refers to digital transmission, and "telecommunications" or "telecom" refers to a mix of voice and data, both analog and digital. "Networking" refers specifically to LANs and WANs.\n\nThe term "communications" used by itself generally pertains to telecom-related subjects such as PBXs, modems, call centers and the like. However, the word is also a generic English word that is used descriptively such as in the headline "Analog Vs. Digital Communications" below. Thus, "communications" is used specifically in some cases and more generically in others.

This is a high speed internet connection, usually through cable, dsl or wifi.\n\n"A transmission medium capable of supporting a wide range of frequencies, typically from audio up to video frequencies. It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies."

actually electronics and comm. engineering comes under one stream only.but taking aspect of industry a communication engineer works in the field of wireless,gsm and other technologies of communication.

In the true meaning, information technology is anything (from a paper form to a cell phone or computer) that allows people to organize and share information.\n\nIt is the media that we use to store and communicate ideas.\n\nIn the usual meaning, it refers to electronic devices that do the above.  In this instance the organization of information can be quite advanced and includes the ability to search and otherwise process information.\n\nThe detailed part of your question sounds like a homework question.  You should be able to imagine how writing implements first changed the world and how cell phones and computing is currently doing so.

Communications is one of the greatest asset given to man. Without it, how can we socialize, or get anything done?

Technology Reaches “Brave New World” Proportions—The Human Body as Broadband Connection\n\nA new technology developed by a Japanese communications company called Nippon Telegraph and Telephone Corporation (“NTT”) uses the human body for broadband networking. More specifically, NTT’s RedTacton technology sends data over the surface of the skin at speeds equivalent to a fast broadband data connection.\n\nOther companies, most notably, IBM and Microsoft, have done work in this field, but NTT is the first company to figure out how to transfer data over the skin without attaching transmitters to the human body. Instead, the transmitters can be built into devices such as an MP3 player or a cell phone and are effective within 20 centimeters of the human body. Using the RedTacton transceiver, data can be transmitted by touching, holding, sitting, walking, or stepping on a particular spot. Data can even travel through clothing and shoes.\n\nThe way the RedTacton technology works is by coupling a transmitter with weak electric fields on the surface of the body. These electric fields pass through the body to a RedTacton receiver, where they come into contact with an electro-optic crystal. A sensor then bounces a laser beam off the crystal and measures the reflected beam. The polarization of the reflected light is affected by oscillations in the electric fields surrounding the crystal; therefore, the electric fields that pass over the body influence the characteristics of the reflected beam. The reflected light is then\n  converted back into electric signals to receive the transmitted data. Sound like magic? The NTT technology is based on a technique called electric field photonics.\n\nIn terms of safety, according to NTT, the RedTacton transceiver electrodes are covered with an insulating film that prevents current from the transceiver from flowing into the user’s body upon contact. The company notes, however, that the RedTacton technology does create in the body the same level of weak induction current as cell phones.\n\nNTT has several Japanese patents covering its technology and is “patent pending” in foreign countries. NTT’s technology is an improvement over previous technologies developed by Microsoft and IBM. In the mid-1990s, IBM developed the first personal area network (“PAN”). This PAN allowed two people to transmit business card information to each other electronically via a handshake. In June of 2004, Microsoft obtained a patent on a “method and apparatus for transmitting power and data using the human body.” Microsoft’s patent, however, required a pair of electrodes to be attached to the body.\n\nWhy all this interest in PANs? Some feel these types of communications are more secure; others feel they have potential application in the medical device arena. Technology has already been developed that allows humans to communicate with computers using their thoughts only. What is clear is that we have entered a new world where humans and computers are linked more intimately than they ever have been before.

Information technology (IT, also known as Information and Communication(s) Technology (ICT) and Infocomm, especially in Asia) is a broad subject concerned with technology and other aspects of managing and processing information, especially in large organizations.\n\nIn particular, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. For that reason, computer professionals are often called IT specialists, and the division of a company or university that deals with software technology is often called the IT department. Other names for the latter are information services (IS) or management information services (MIS), managed service providers (MSP).\n\nIT (information technology) is a term that encompasses all forms of technology used to create, store, exchange, and use information in its various forms (business data, voice conversations, still images, motion pictures, multimedia presentations, and other forms, including those not yet conceived). It's a convenient term for including both telephony and computer technology in the same word. It is the technology that is driving what has often been called "the information revolution."
