3. 1.0 Introduction
The latest development in networks and communication means the improvement in networks and
communication services and products which really useful for IT user. It is also much better from the
previous contains.
2.0 Mobile Computing.
2.1 Definition.
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

4. satellites, radio systems and lasers to transmit between permanent objects such as buildings and
towers.

3.0 Internet Technology And services
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

6. 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
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.

7. 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
4.3 WIMAX
Worldwide Interoperability for Microwave Access (WiMAX) is a communications technology
thatuses 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.
5.0 Conclusion
The latest development in networks and communication brings more useful to IT user which can
makes lifes way easier in networking and communicate.
