Mobile Computing Applications
Mobile computing
is human–computer interaction by which a computer is expected to be
transported during normal usage. Mobile computing involves mobile
communication, mobile hardware, and mobile software. Communication
issues include ad hoc and infrastructure networks as well as
communication properties, protocols, data formats and concrete
technologies. Hardware includes mobile devices or device components.
Mobile software deals with the characteristics and requirements of
mobile applications. - Wikipedia
Examples of applications such as mobile banking :
Push Email
Push
email is an email system that provides an always-on capability, in
which new email is actively transferred (pushed) as it arrives by the
mail delivery agent (MDA) (commonly called mail server) to the mail user
agent (MUA), also called the email client. Email clients include
smartphones and, less strictly, IMAP personal computer mail
applications.
In
Blackberry, BlackBerry uses wireless mail user agent devices and a
BlackBerry Enterprise Server (BES) attached to a traditional email
system. The BES monitors the email server, and when it sees new email
for a BlackBerry user, it retrieves (pulls) a copy and then pushes it to
the BlackBerry handheld device over the wireless network.
BlackBerry
became very popular, in part because it offers remote users "instant"
email; new emails appear on the device as soon as they arrive, without
the need for any user intervention. The handheld becomes a mobile,
dynamically updating, copy of the user's mailbox. As a result of the
success of BlackBerry, other manufacturers have developed push email
systems for other handheld devices, such as Symbian- and Windows
Mobile-based mobile phones. However, they only support push email for
some email services.
With
the release of the BlackBerry 10 operating system for its new
generation of mobile device, BES is no longer available for
non-corporate client email delivery. Instead, BlackBerry 10 offers POP,
IMAP, or ActiveSync for transferring email to and from a device. Of
these, the latter two can provide push email delivery if the server
supports it.
Mobile Banking
Mobile
banking is a system that allows customers of a financial institution to
conduct a number of financial transactions through a mobile device such
as a mobile phone or personal digital assistant.
Mobile
banking differs from mobile payments, which involve the use of a mobile
device to pay for goods or services either at the point of sale or
remotely,analogously to the use of a debit or credit card to effect an
EFTPOS payment.
The
earliest mobile banking services were offered over SMS, a service known
as SMS banking. With the introduction of smart phones with WAP support
enabling the use of the mobile web in 1999, the first European banks
started to offer mobile banking on this platform to their customers.
Mobile
banking has until recently (2010) most often been performed via SMS or
the mobile web. Apple's initial success with iPhone and the rapid growth
of phones based on Google's Android (operating system) have led to
increasing use of special client programs, called apps, downloaded to
the mobile device. With that said, advancements in web technologies such
as HTML5, CSS3 and JavaScript have seen more banks launching mobile web
based services to complement native applications. A recent study (May
2012) by Mapa Research suggests that over a third of banks have mobile
device detection upon visiting the banks' main website. A number of
things can happen on mobile detection such as redirecting to an app
store, redirection to a mobile banking specific website or providing a
menu of mobile banking options for the user to choose from.
From
the above explanation, we can conclude that Mobile computing
applications are required to inform a news or information in the state
of moving (mobile).
From
Mobile computing applications make us easy to do something more fast.
We just need install the application what we need on our mobile
computing. There are free and paid. This is mobile computing
appliation that many people use :
- Database queries over the static network for information such as weather,or trac conditions, and performing share transactions, or home shopping.
- Client{server applications, such as World Wide Web (WWW) browsing, electronic mail, Usenet news, and remote sessions on static computers.
- Multimedia applications, such as a video phone, television broadcasts, video mail, and video on demand.
- Collaborative working, requiring a group protocol for distributed transactions and floor control.
