1.0Introduction
The latest development in networks and communication means the improvement in networks and communication services and products which really useful for IT user. It is olso much better from the previous contains.
2.0 Mobile Computing.
2.1Definition.
Using a computing device while in transit. Mobile computing implies wireless transmission,but
wireless transmission does not necessarily imply mobile computing. Fixed wireless applications use
satellites, radio systems and lasers to transmit between permanent objects such as buildings and towers.
2.2 Specification, services & frequencies of Mobile Computing
Sony Ericsson Xperia Arc
Russian website has published a story on the Sony Ericsson Xperia Arc. An official announcement will be expected shortly but here is what we have for now

3.0 Internet Technology And services
Internet Services Technology is broad field of study usually resulting in receiving an Associate of
Applied Science Degree. This 2-year degree, often awarded at community colleges, is a gateway to
more specialized studies but can also be applied to immediate workforce demands. Students learn
languages such as HTML, C++, Action Script, and Java Script. This program of study also
encompasses business courses with an emphasis on e-commerce and macroeconomics.
Internet Services Technology covers a broad range of technologies used for web development, web
production, design, networking, and e-commerce. The field also covers Internetprogramming,website maintenance, Internet architect, and web master.
3.1 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 packet-switched
networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet
telephony, voice over broadband (VoBB), broadband telephony, and broadband phone
3.2 Blog
A blog (a contraction of the term weblog) is a type of website, usually maintained by an individual
with 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 a
verb, meaning to maintain or add content to a blog.
4.0 Types Of Network
One way to categorize the different types of computer network designs is by their scope or scale.
For historical reasons, the networking industry refers to nearly every type of design as some kind of
area network. Common examples of area network types are:
•pan
•wlan
•wimax
4.1 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. The devices may
or may not belong to the person in question. The reach of a PAN is typically a few meters. PANs
can be used for communication among the personal devices themselves (intrapersonal
communication), or for connecting to a higher level network and the Internet (an uplink).
Personal area networks may be wired 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 and ZigBee.
4.2 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
4.3WIMAX
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. Similar to WiFi, WiMAX brings with it the ability to transmit over far greater distances and to handle much more data.
5.0Conclusion
The latest development in networks and communication brings more useful to IT user which can
makes lifes way easier in networking and communicate
