2. Introducing Mobile Computing
• Mobile Computing
Mobile (moving)
+
Computing (using computer)
Mobile computing = is an umbrella term
used to describe technologies that enable
people to access network services
anyplace,anytime,and anywhere.
3. Mobile computing
• In recent years, distributed computer has become
the norm, especially after the advent of the
internet.
• Today, technological advances are shaping a new
computing environment where the user is free
from the need to work at a specific location, and
is even enabled to work while on the move.
• This new paradigm is often called mobile
computing.
4. Mobile Computing Device
• LAPTOP
• Portable and compact personal
computer with the same capabilities
as a desktop computer.
• TABLETS
A small portable computer that accepts input
directly on to its screen rather than via
a keyboard or mouse.
5. • CELLPHONE
A phone with access to a cellular radio system so
it can be used over a wide area, without a
physical connection to a network; a mobile
phone.
• LONG-RANGE WIRELESS
Connected devices have so far mostly run
piggyback on the same networks and protocols
that support the Internet and mobile
communications
6. Going Mobile beyond the Enterprise
• Mobile technology along with bring-your-own device
(BYOD) has largely transformed our lives, including the way
we work. But enterprise mobility is more than simply
providing remote access to users. It is rather a shift in work
habits where employees can work remotely leveraging
mobile devices and cloud technology to better perform
business tasks.
• The mobile revolution is changing the way organizations
work, manage their operations as well as engage with their
employees. As a result, organizations are reconsidering
their technologies and techniques to make their traditional
organizational cultures and roles more mobile friendly,
making ‘mobile first’ a must have strategy.
7. Navigation
• Many external navigation sites like the major
search engines exist to return thousands of links
for almost any topic you might happen to be
curious about.
• A DNS server would start its search for an IP
address by contacting one of the root DNS
servers. The root servers know the IP addresses
for all of the DNS servers that handle the top-
level domains (.COM, .NET, .ORG, etc.).
8. Connectivity
Connectivity describes the extensive process of
connecting various parts of a network to one
another, for example, through the use of
routers, switches and gateways, and how that
process works.
9. Bandwidth
• Bandwidth describes the maximum data
transfer rate of a network or Internet
connection. It measures how much data can
be sent over a specific connection in a given
amount of time. For example, a
gigabit Ethernet connection has a bandwidth
of 1,000 Mbps, (125 megabytes per second).
An Internet connection via cable modem may
provide 25 Mbps of bandwidth.
10. VPN and SSL access
• A VPN or Virtual Private Network is a method used to
add security and privacy to private and public
networks, like WiFi Hotspots and the Internet. VPNs
are most often used by corporations to protect
sensitive data.
• SSL (Secure Sockets Layer) is the standard security
technology for establishing an encrypted link between
a web server and a browser. This link ensures that all
data passed between the web server and browsers
remain private and integral. SSL is an industry standard
and is used by millions of websites in the protection of
their online transactions with their customers.
11. Remote desktops
• Remote desktop is a program or an operating
system feature that allows a user to connect
to a computer in another location, see that
computer's desktop and interact with it as if it
were local.
