PDA .0 Introduction The latest development in networks and communication means the improvement in networks and communication services and products which really useful for IT user. services & frequencies of Mobile Computing.1.0 Mobile Computing. Mobile computing implies wireless transmission. radio systems and lasers to transmit between permanent objects such as buildings and towers. but wireless transmission does not necessarily imply mobile computing. 2. It is olso much better from the previous contains.2 Specification. Using a computing device while in transit. 2. 2. Fixed wireless applications use satellites.1Definition.

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

2 virtual private network (VPN) virtual private network (VPN) is a network that uses primarily public telecommunication infrastructure. WiMAX brings with it the ability to transmit over far greater distances and to handle much more data.4. and often secure data with encryption technologies to prevent disclosure of private information to unauthorized parties. VPNs typically require remote users of the network to be authenticated. 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.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. to provide remote offices or traveling users access to a central organizational network. such as sharing of data and access to network resources. VPNs may serve any network functionality that is found on any network. Similar to WiFi. such as the Internet. . This gives users the mobility to move around within a broad coverage area and still be connected to the network 4. databases.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. printers. A VPN user typically experiences the central network in a manner that is identical to being connected directly to the central network. etc. 4. websites.
