Mobile Computing Essentials

By
R
ussel

CP

Mobile computing is the ability to do computing tasks in some or all possible lo
cations. Here, I'll
be listing
the top 4 requirements for mobi
le computing and my suggestions

or
opinions on those
requirements.

Portability

It is

common sense: if your computers or mobile devices are too heavy to carry around they are
useless for mobile computing. Gone are the days o
f lugging around heavy laptops.

A good
example of a very portabl
e computing device is the Apple MacBook Air: It

i
s small and thin
enough to put in an envelope. Also good examples are the humble netbooks. These small,
almost pocket sized computers are small and light enough that you can almost put them inside
your coat
pockets or purses. They offer relatively good processing power for the basic computing
needs, up to 15 hours of battery life (depending on use) and are cheaper than most full size
notebooks. Since
Asus

came out with the original Ultra Mobile Personal Compu
ter (UMPC), the
EEEPC, almost all computer companies have created their own netbook line.

Now, with the release of the Apple iPad tablet, Tablet Computing
has

been put in spotlight again.
Major computer brands are following with Samsung releasing the Galax
y Tab and HP developing
and hopefully finally releasing the Slate,
and Asus announcing the EeePads.


Battery Life

Even if you have the fastest and lightest computing devices (laptops, mobile phones, tablets,
etc.) but you don't have enough power to support

them, they are practically useless for mobile
computing. A couple of hours of power

are

the current sta
ndard for most laptops. If your

laptop's battery lasts for three hou
rs
,

that

is

already above average.

With netbooks, three hours is just the average. B
ecause of the development of low power
consuming processors and LED displays, and also the development of higher capacity, compact
lithium ion/ polymer battery packs, we have netbooks that can stay powered for more than 8
hours. Example of such laptops are

the next generation Acer Aspire One 533, ASUS Eee PC
1015,

MSI U160, HP Mini 210 Series. Imagine this scenario: You fully charge your netbook
before you start the day and then use it unplugged for the whole day. Now that's you call "truly
13


mobile computing
". With smartphones, especially those that utilizes a lot of 3G connectivity, a
full day of operation is adorable: anything less is just normal.


Internet Connectivity

Staying connected to the Internet is one of the basic requirements for mobile computing.

Unless
you don't have any use for the Internet, your mobile computing device should at least have a
built
-
in wireless network adapter, also known as
Wi
-
Fi

card. Another essential device for staying
connected with your netbook or laptops is a mobile broadb
and device like the 3G USB modems,
pcmcia cards, and built
-
in 3G modems in several netbooks and laptops. The latest smartphones
take full advantage of 3G networks: they can work outside
Wi
-
Fi

hotspots. The only downside to
that is the rapid loss of battery

life.

Durability

Mobile computing has the most demanding requirements for devices especially when it comes to
durability. Because mobile computing is done anywhere and everywhere, the devices you use
should be able to survive the most number of scenarios.

And when we talk about durability in
mobile computing, nothing beats the Panasonic ToughBook.
These lines of laptops from
Panasonic were

designed to handle the most de
manding computing environments.

Tips

Before buying any mobile computing device, make sur
e you research well about the product.
The best way to gauge if the device meets your needs and wants is to try the actual device.

It is
better
i
f you can try the device for a day
.

Always buy mobile computing devices with at least one year warranty. That g
ives you a small
sense of security when your device fails within the first year.

When it comes to durability, most mobile computing devices like laptops, netbooks,
smartphones, and tablets have operational guidelines that you should follow. If you use thes
e
devices outside their prescribed conditions, you risk voiding the warranty. Examples are using
the device under the rain, vibrating platforms, sand
-
prone and water
-
prone places like the
beach, and other uncommon locations.

Benefits of DBMS


Database management system simply refers to handling and managing of data. It is commonly
used in small and large organizations t
o allow the collection of data, as well as background
integration. It facilitates users to access information
easily.


1. Easy data control

Since all the information is centralized, you don’t need to duplicate data. Unlike traditional paper
systems, all us
ers can get the data firsthand without making new copies. Likewise, database
management system helps to remove the cost of duplication resulting from single application
programs.


2. Accuracy

Because data is stored on multiple computers software, handling
data becomes easier. In
addition, organizations use database management system to maintain accuracy of information.
By doing so, they are able to enforce high standards.


3. Data security

Of all the benefits, this is one of the most important features of
database management system.
Data is restricted only to those who are certified to manipulate it, therefore preventing breach of
information by unscrupulous individuals.


4. Better processing speed

The responsiveness of data management using computer system
s is better with a well
-
versed
DBMS, as compared to linear computer applications. For instance, functions such as sum,
calculate, and count are automated with ease. In a data management system, the applications
to report, store, and update the data are pla
nned in an orderly manner.


5. Reuse of data code

The best thing about data management system is that each part can reuse code from other
modules or sections. For instance, inventory data is stored in a section that is separate from
another set of data. Ne
vertheless, queries are combined from all the modules without having to
change their structure.


Since all the data is combined into one single database, power outage or corrupted database
may result in
loss
of information.
