Personal area networks may be wired with computer buses such as USB and FireWire.1 Voice Over Internet Protocol ( VoIP) Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packetswitched networks.0 Types Of Network 4. UWB. or for connecting to a higher level network and the Internet (an uplink). Entries are commonly displayed in reverse-chronological order. or other material such as graphics or video. The reach of a PAN is typically a few meters. 4. The devices may or may not belong to the person in question. Z-Wave and ZigBee. Other terms frequently encountered and synonymous with VoIP are IP telephony. A wireless personal area network (WPAN) can also be made possible with network technologies such as IrDA. and broadband phone. 3. usually maintained by an individual with regular entries of commentary. broadband telephony. meaning to maintain or add content to a blog. Bluetooth. . Internet telephony. PAN can be used for communication among the personal devices themselves (intrapersonal communication). descriptions of events.Internet Technology And services 3. voice over broadband (VoBB). "Blog" can also be used as a verb.2 Blog A blog (a contraction of the term weblog) is a type of website.1 Personal Area Networking (PAN) A personal area network (PAN) is a computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person.

databases. VPNs may serve any network functionality that is found on any network. etc.2 virtual private network (VPN) virtual private network (VPN) is a network that uses primarily public telecommunication infrastructure. such as the Internet. Similar to WiFi. 4.4 WIMAX Worldwide Interoperability for Microwave Access (WiMAX) is a communications technology that uses radio spectrum to transmit tens of megabits per second in bandwidth between digital devices such as laptop computers. WiMAX brings with it the ability to transmit over far greater distances and to handle much more data. printers. VPN technology via the public Internet has replaced the need to requisition and maintain expensive dedicated leased-line telecommunication circuits once typical in wide-area network installations. VPNs typically require remote users of the network to be authenticated. such as sharing of data and access to network resources.4. to provide remote offices or traveling users access to a central organizational network. A VPN user typically experiences the central network in a manner that is identical to being connected directly to the central network.3 Wireless LAN (WLAN) A wireless LAN (WLAN) is a wireless local area network that links two or more computers or devices using spread-spectrum or OFDM modulation technology based to enable communication between devices in a limited area. . This gives users the mobility to move around within a broad coverage area and still be connected to the network 4. and often secure data with encryption technologies to prevent disclosure of private information to unauthorized parties. websites.
