A cell phone is a two-way radio that sends and receives radio signals to and from cell site base stations. When a person talks on a cellular phone, the voice message gets converted into radio waves. The radio waves travel through air until they reach a base station close by. The base station sends the call across the communication network after which the call reaches the intended receive…
A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area.

Can you imagine staring at a screen for four years? The average human will spend four years total staring at their phone, if not more (Doc 7). With the technological advancements our world grew to, our people followed in the growth. By doing so, our human emotions are being replaced with “like” and “dislike” buttons, and our brains only want to learn something if it’s within the first three links in a Google search engine. Students and parents should limit their use of cell phones because they isolate our emotions, they negatively affect our body and mind, and keep us seperated from relationships with people.…
Even though PDAs had innovative and sophisticated product designs, companies failed due to several reasons. First, enabling technologies were not up to par and such features as wireless connectivity, greater processing power, longer battery life and replicating streamlined versions of office software compromised the performance and size of the PDA. Another reason was due to the lack of market awareness about the functionality and the future potential of pen-based PDA and the market was still undeveloped in terms of such technology. With the lack of publicity, how would the public see any use for a PDA? This was especially true for a generation that was not technologically driven as we are today. With a device more expensive than desktop systems, it seemed that without proper marketing the public would not understand the need for it. Furthermore, potential users were unsure of the PDA’s performance, compatibility and availability showing how companies failed to address user needs and did not focus on the type of consumer that would most likely buy such a device. In addition to these setbacks, Microsoft stalled the market acceptance of PDA technology when it announced it was planning on a making a PDA, but failed to follow through with it. It is obvious that companies producing PDAs could have developed successful marketing tactics to gain momentum and build a consumer base upon such publicity. However, it can be debated whether the PDA could of survived the emergence of the smart phone. Although many companies such as Momenta and GO failed in the PDA business, Palm proved to be the most victorious. The PalmPilot was successful because the product was fast, simple, and was available for less than $300.…
Communication has evolved in several ways since the beginning of time. A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The telephone allows people to communicate with others that are not around them. In modern day society people use texting and calling several times a day to communicate with people in a convenient manner. The popularity of the cellphone has made it possible to make calls or texts to communicate with those that are not immediately around one. Texting and calling are both very easy means of being able to reach someone or to send a message. Calling and texting are both means of communication and have many similarities, however, are different in many aspects.…
