I will
discuss telecommunication hardware, and the difference between a mobile phone,
PDA, and smartphone. In the past, the purpose of cellular phones was to send
and receive voice communications, but today, they have multiple functions.
Mobile phones can be used to run software, access the internet, take pictures,
and play music. Their differences make each phone unique; the price will tell
you.
A mobile phone is a wireless
device that connects to cell phone towers using radio waves. Mobile phones can
be used for voice communication, Short
Message Service (SMS), Multimedia Message Service (MMS), and newer phones may
use instant messaging.[1] I use
to own a mobile phone, and the durability was better than my smartphone. The phone could drop or get scratched, and It
will still work.
A PDA is an acronym for
“Personal Digital Assistant”. The purpose is simple: to facilitate the
organizing of daily activities in an easily manageable, portable way. [2] These devices are handheld which have
computing, telephone, and internet (with WiFI technology). However, through
evolution, keyboards have been installed on these devices. Most PDA’s have touch screens, while some
also have fax services. Most PDA’s are used as a personal organizer. Some PDA’s
have voice recognition technology for speed dialing and going through menus. An
example of a PDA is a Pixi Plus[3]
phone by the company of Palm. [2]
A smartphone
is a combination of a PDA and a mobile phone, “which in
essence was just like a regular cell phone with some added capabilities that
you may find on a laptop or PC”. [4] Smart phones are like
mini-computers. They are used for used primarily for e-mail and applications. Most
Smartphones now have a touch screen. A touch screen is a display where I can
use my finger to input commands. An example of a smartphone is Apple’s iPhone
(with iPhone OS) and Samsung’s Galaxy SII (with Android OS). These smart phones
have advanced 3D graphics and more powerful hardware. Although they are more
like PDA’s, no standard defines a smartphone. Smartphones are usually greater
than PDA, and a PDA is greater than a mobile phone in ability.
In
conclusion, mobile phones, PDAs, and smart phones all have different uses.
Before purchasing a cellular phone, a person should reflect on the level of
cell phone usage. Simple users may be happy with a simple phone with call and
text functions. More courageous users may want a PDA for its entry-level pen.
Advances users may want a smartphone to help with their daily life. Regardless
of who uses what kind of cellular phone, the average user may need to be more
proficient in computers as cellular phones may replace PCs in the future.
