Task 3.4


                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.
