Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes are implemented without the use of wires.[1] Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or "layer" of the network.

Home > VPN VPN(pronounced as separate letters) Short for virtual private network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Voice over Internet Protocol (VoIP, Voice over IP) is a general term for a family of methodologies, communication protocols, and transmission technologies for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone. Internet telephony refers to communications services - voice, facsimile, and/or voice-messaging applications - that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.[1] VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

CNET Networks Inc. is a media company co-founded in 1993 by Halsey Minor and Shelby Bonnie. CNET was also originally an acronym that originally stood for Computer Networks, but the name was later changed to CNET Networks, losing its acronymity. It was acquired by CBS in 2008 and its properties were merged into CBS Interactive. Contents [hide]

"This weekend saw a number of prominent technology observers questioning the value of social networks, including This Week in Tech host Leo Laporte, who penned a thoughtful post on why he's leaving Google Buzz behind. Laporte said he feels that his last four years of social networking use have been an "an immense waste of time," but I think he and others are missing the larger point. Too many people seem to be trying to use social networks for media and marketing activities instead of the core reason such networks exist: namely, to connect people."

By Wendy Drexler The Networked Student was inspired by CCK08, a Connectivism course offered by George Siemens and Stephen Downes during fall 2008. It depicts an actual project completed by Wendy Drexler's high school students. The Networked Student concept map was inspired by Alec Couros' Networked Teacher. I hope that teachers will use it to help their colleagues, parents, and students understand networked learning in the 21st century.

"Mobile technology is exactly what the name implies - technology that is portable. Examples of mobile IT devices include: laptop and netbook computers palmtop computers or personal digital assistants mobile phones and 'smart phones' global positioning system (GPS) devices wireless debit/credit card payment terminals Mobile devices can be enabled to use a variety of communications technologies such as: wireless fidelity (Wi-Fi) - a type of wireless local area network technology Bluetooth - connects mobile devices wirelessly 'third generation' (3G), global system for mobile communications (GSM) and general packet radio service (GPRS) data services - data networking services for mobile phones dial-up services - data networking services using modems and telephone lines virtual private networks - secure access to a private network It is therefore possible to network the mobile device to a home office or the internet while travelling. Benefits Mobile computing can improve the service you offer your customers. For example, when meeting with customers you could access your customer relationship management system - over the internet - allowing you to update customer details whilst away from the office. Alternatively, you can enable customers to pay for services or goods without having to go to the till. For example, by using a wireless payment terminal diners can pay for their meal without leaving their table. More powerful solutions can link you directly into the office network while working off site, for instance to access your database or accounting systems. For example, you could: set up a new customer's account check prices and stock availability place an order online This leads to great flexibility in working - for example, enabling home working, or working while travelling. Increasingly, networking 'hot spots' are being provided in public areas that allow connection back to the office network or the internet.

"A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device which can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile network operator. The calls are to and from the public telephone network which includes other mobiles and fixed-line phones across the world. By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these more general computing capabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing 2 1/2 lbs (about 1 kg).[1] In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions grew from 12.4 million to over 4.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid"

"The internet has changed the lives of people around the world. It has never before been easier to acquire various types of information and to reach people around the world by entering social online networks, such as Facebook. However, the infinity of the internet also leads to information overflow. Likewise, the majority of social online networks address private people, oftentimes leaving the opportunities from which the professional world could benefit unused. Thus, modern web tools which filter information and social networks that enable people to easily communicate, network and share knowledge with each other in the professional context are a tremendous help.

"The eDonkey network (also known as the eDonkey2000 network or eD2k) is a decentralized, mostly server-based, peer-to-peer file sharing network best suited to share big files among users, and to provide long term availability of said files."

" "It was the first service network to offer traditional cable, interactive television, telephone services, and high-speed PC access by integrating them over a fiber-optic and coaxial cable network, which has now become an industry standard"

In this page it talks about winning an Emmy for workflow software because they were the first service network to offer multiple things in one.

Will new wireless network technology cause a hindering problem that will possibly lead to a decrease in security? The military's high-tech wireless networks may be effected by these new technologies, and Senator Charles Grassley explains.

Definition of a Social Network.

This explains what a social network is,and the history of it.

A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network
