1.0 IntroductionThe latest development in networks and communication means the improvement in networks andcommunication services and products which really useful for IT user. It is also much better from theprevious contains.2.0 Mobile Computing.2.1 Definition.Using a computing device while in transit. Mobile computing implies wireless transmission,butwireless transmission does not necessarily imply mobile computing. Fixed wireless applications use
satellites, radio systems and lasers to transmit between permanent objects such as buildings andtowers.2.2 Specification, services & frequencies of Mobile Computing.Mobile Computing PDA, HD PSPSPECIFICATION 1.Low bandwith. 2.High bandwith variability. •Low power machines 3.Hidden terminal. •enable anywhere 4.Low power machines. 5.Low resources machines •low resources machines. 6.need proximity 7.higher delay 8.disconnected operation
9.enable anywhere/anytime connentivity. 10.Enable new application.SERVICES 1.Emergency services •games (messaging & calling) 2.stock information.Collection /control. 3.Credit card verification. 4.Taxi/truck dispatch. 5.Electronic mail/pagingFREQUENCIES •EGSM 900/1800/1900 •none •UMTS 21003.0 Internet Technology And services3.1 Voice Over Internet Protocol ( VoIP)Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies fordelivery of voice communications over IP networks such as the Internet or other packet-switchednetworks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internettelephony, voice over broadband (VoBB), broadband telephony, and broadband phone.3.2 BlogA blog (a contraction of the term weblog) is a type of website, usually maintained by an individualwith regular entries of commentary, descriptions of events, or other material such as graphics or
video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as averb, meaning to maintain or add content to a blog.4.0 Types Of Network4.1 Personal Area Networking (PAN)A personal area network (PAN) is a computer network used for communication among computerdevices (including telephones and personal digital assistants) close to one person. The devices may ormay not belong to the person in question. The reach of a PAN is typically a few meters. PANs can beused for communication among the personal devices themselves (intrapersonal communication), orfor connecting to a higher level network and the Internet (an uplink). Personal area networks may bewired with computer buses such as USB and FireWire. A wireless personal area network (WPAN)can also be made possible with network technologies such as IrDA, Bluetooth, UWB, Z-Wave andZigBee.
4.2 Wireless LAN (WLAN)A wireless LAN (WLAN) is a wireless local area network that links two or more computers ordevices using spread-spectrum or OFDM modulation technology based to enable communicationbetween devices in a limited area. This gives users the mobility to move around within a broadcoverage area and still be connected to the network4.3 WIMAXWorldwide Interoperability for Microwave Access (WiMAX) is a communications technologythatuses radio spectrum to transmit tens of megabits per second in bandwidth between digital devicessuch as laptop computers. Similar to WiFi, WiMAX brings with it the ability to transmit over fargreater distances and to handle much more data.5.0 ConclusionThe latest development in networks and communication brings more useful to IT user which canmakes lifes way easier in networking and communicate.6.0 Referenceshttp://www.pcmag.com/encyclopedia_term/0,2542,t=mobile+computing&i=47137,00 asphttp://answers.yahoo.com/question/index?qid=20070629052817AASZjbYhttp://en.wikipedia.org/wiki/Voice_over_Internet_Protocolhttp://en.wikipedia.org/wiki/Bloghttp://compnetworking.about.com/od/basicnetworkingconcepts/a/network_types.htmhttp://en.wikipedia.org/wiki/Personal_Area_Networkhttp://en.wikipedia.org/wiki/Wireless_LAN
