Type Mobile Computing
• Laptops are portable computers , small and
can be carried anywhere very easily integrated in a casing . Weight
laptops range from 1 to 6 pounds depending on size , materials and
specifications . The power source comes from batteries or A / C adapter
which can be used to recharge the battery and to power the laptop itself
. Usefulness same laptop with a desktop computer , which distinguishes
only the size making it easier for users to carry it around .
•
Wearable Computer or computer that is applied in the human body . An
example is Computer Glacier Ridgeline W200 . W200 is made from
reinforced magnesium alloy which maximizes strength and minimizes
overall weight . At only 10.2 ounces and was formed in the arm contour ,
W200 combines the same features of a standard computer with a device
that provides comfort and ergonomic wrist worn instrument . The W200 has
a 3.5 “color display with touch screen , backlit keyboard and a hot
swappable battery . Wireless function of W200 ensure continuous
connectivity regardless of the user’s location with plug and play Wi –
Fi , Bluetooth and GPS modules . Using Windows CE or Linux operating
systems , the unit can be quickly configured to access the remote host
system through integrated wired or wireless interfaces . Hands – free
operation of the W200 that overcomes the physical limitations associated
with normal hand-held computer . This allows the user complete freedom
to continue their daily activities with both hands while using the
computer has full access at all times . In addition to the electronic
compass , the system also integrates the latest and most innovative
features , such as tilt and silent reckoning , which allows critical
battery savings when the unit is not in use . Hands – free usability of
the W200 makes it of special interest for Emergency Services , Security ,
Defense , Warehouse , Field Logistics and any area where access to a
large amount of information required . W200 ridge line of the glacier
when it joins rugged computers developed for data collection .
• PDAs
( Personal Digital Assistants ) is an electronic device and a computer
-based small form and can be taken anywhere . According to my knowledge
PDAs are widely used as a personal organizer at first , but because of
its development , then multiply its utility function , such as a
calculator , clock and timing pointer , computer games , internet users ,
receiving and sending electronic mail ( e – mail ) , radio receiver ,
video recorder , and a memo recorder . Apart from it with a PDA ( pocket
computer ) , we can use the address book and store addresses , e-book
reading , using GPS and many other functions . Even more sophisticated
version of the PDA can be used as a mobile phone , Internet access ,
intranets , or extranets via Wi – Fi or Wireless Network . One of the
typical PDA is the ultimate touch screen facility
• SmartPhone is a mobile phone offering advanced capabilities , its
ability to resemble capabilities virtually the PC ( computer ) .
Generally, a mobile phone as a smartphone when it is said to be running
on the operating system software that is complete and has a standard
interface and platform for application developers . While some say that a
smartphone is a simple mobile phone with advanced features such as the
ability to send and receive emails , surf the Internet and read e -books
, built -in full keyboard or external USB keyboard , or has a VGA
connector . In other words , the smartphone is a miniature computer with
phone capabilities .

- GIS ( Location )
Excess and deficiency
Advantages of Mobile Computing
- Application wide
- Moving / berpidah freely locations
- Non- switch networks
Disadvantages of Mobile Computing
lack of Bandwidth
Internet
access in peralatanini slow when compared to wired access , but with the
use of technology GPRS , EDGE and 3G networks , high -speed Wireless
LAN is not too expensive but has a limited bandwidth .
power consumption
Mobile computing is highly dependent on battery life .
Transmission disorders
Distance to the transmitter signal and weather affect transimis data on mobile computing .
Potential Occurrence of Accidents
Some accidents are often caused by akhir2 motorists who use mobile computing devices while driving .
Usefulness And Other Issues
As the use of mobile Internet using
mobile internet sites , the ability of the site to be able to use
(usability ) is important to attract and retain the attention of ” user
stickiness ” ( the degree to which the user remain our site ) . There
are three dimensions of usability , ie effectiveness , efficiency and
satisfaction . However, users often find today’s mobile devices are not
effective , especially because of restrictions pocket-sized keyboard and
services , thus reducing its usefulness . Moreover, due to the limited
storage capacity and speed of access to information than most
smartphones and PDAs , as difficult or impossible to download large
files from the per Alatan this kind . Technical limitations and other
restrictions that slow the spread of m – commerce .
Failure In Mobile Computing and M – Commerce
Same
with other technologies , especially new ones , there are many failures
of the application and of the whole company in the mobile computing and
m – commerce . It is important to anticipate and plan for the
possibility of failure and learning from failure . Case Northaest
Utilities beberikan some important insights .
The existence Impact of Modern Computing
The
impact of modern computing is that it can help people to solve complex
problems using computers . One example is a biometric . Biometric
derived from the Bio and Metric . The word bio is taken from the ancient
Greek language which means life , while Metric is also derived from the
ancient Greek language , which means the size , so if concluded
biometric means of life measurements .
But an outline of a biometric
measurement of the statistical analysis of biological data that refers
to the technology to analyze the characteristics of a body ( people) .
From these explanations it is clear that describe Biometric detection
and classification of physical attributes . There are many different
biometric techniques , including :
• Reading of fingerprints / palm
• Hand geometry
• Reading of the retina / iris
• Voice recognition
• The dynamics of signatures .
And
according to Don Tapscott (1995 ) in his book entitled ” The Digital
Economy : Promise and Peril In The Age of Networked Intelligence ”
illustrates how the impact of computing technology on human life .
Application technology is less than perfect without the support of
intelligent machines capable analytic . The presence of increasingly
sophisticated computing technology has changed human lifestyle and the
demands on human competence . Now human life increasingly dependent on
computers . Here are the things that describe the concept of
computational intelligence technologies are supported by the application
.
1 . Product -driven computer system
a. Smart car ( car smart )
b . Smart card ( smart card )
c . Smart house ( smart home )
d . Smart road ( street smart )
2 . The design of the product is managed by a computer
3 . The process is driven by a computer work
4 . Computers became an effective means of communication
5 . Computer as an information center
In
addition to the structural impact on human livelihoods , technology
also evokes cultural processes in society diterpanya . It is a symptom
that by N. Postman called technopoly , which is described by him as
follows :
” Technopoly is a state of culture . It is also a state of
mind . It Consist in the deification of technology , the which means
that the culture seeks it’s satisfactions in technology , and takes it’s
orders from technology “
Thus , what matters is the extent to which a
society ready to enter an age characterized by the supremacy of the
power plant technology as a new culture without cause risk resilience
own culture . Thus , it is not wrong to state that also technological
dominance will continue with the blossoming of a new culture that gave
birth to various new value also tends to be the benchmark of modern
human behavior in a variety of patterns of interaction with others .
Trends in Mobile Computing
Mobile
devices have a radical impact on the different routines of individuals
from the modern era . The introduction of the phone itself to change the
communication pattern in previous years and the technology continues to
evolve , now leave marks on other parts as well . Mobile computing not
only provides the basic functions of communication , but to help other
users in performing everyday tasks such as arranging tasks , social
sharing , taking pictures and other computing tasks .
Data capability , with the introduction of wireless networks , mobile
devices are also provided in advanced . Mobile technology also adds a
new variation and improvisation in order to improve the overall user
experience of mobile . Some of the new trends that have been introduced
in mobile computing , in recent years are :
Smart -phone Computing: The third-party application development
for various smartphone platforms such as iOS , Android , Windows mobile ,
etc. have improved graphics innovation and functionality in this
application . Different concepts such as BYOD and mobility companies
have introduced the use of smart-phone applications as enterprise
application to different domains of industry .
Security on mobile phones : With mobile phones becoming smarter
every day , the data handling capabilities become an integral part of
mobile computing . The device is also connected to the network at any
time , so the need to secure data stored also appeared . Because the
mobile security becomes an important component of mobile computing ,
because the purpose of the communication device has been developed from
voice to data.
Wireless Networking : different network technologies such as 4G
and WiMAX are also introduced recently which raised computational tasks
of data from devices and provide high speed accessibility of data from
these devices . This is helpful for users who require large amounts of
data transfer from their handheld devices .
M – commerce : Online trading activities has become a common
activity for the user , for the shopping experience a laxative . With
the growing practice of mobile computing , users can now perform the
same tasks using their hand-held mobile phone or tablet device that is .
Different security parameters are taken care of in the event, which
involves the processing of financial information . Unlike the mobile
payment application has also been introduced to cement a strong
foundation of m – commerce activity .
Another location -based mobile application service which uses a
special system called the Global Positioning System , or GPS , which was
introduced which allows users to gain access to the information from
the various locations of their device .
Different maps like Google maps facility allows users to get turn-by –
turn navigation from their source of travel to their destination
address . Different camera apps also introduced the use of GPSs with
Geo-tagging feature so that users can customize the map view them
according to their needs .
