Cell Phones: Cell phones are both used for voice and data communications. A cell phone now can either make phone calls or browse the web. Cell phones can be used for almost anything now days. Landline Phones: A Landline phone will mainly be used for voice communications. Some landline phones may have caller ID.
Call forwarding allows calls to be directed to different offices and people for different reason, if no one answers or it’s a different department which is needed. Speed dial is a quick way to set someone’s number which you can easily call for example in needs of emergency. A group connection which is mostly for businesses connects the whole business in a conference call allowing employees to hear and speak together as a group. Voice mail: One common and frequently used feature on modern telephone systems are voice mail. If a person is unable to take a call or is already on the phone a voice mail allows the caller to record messages which can be accessed at your own convenience.
1.1 My telephone at work has several different features such as, make call, hold call, transfer call and loudspeaker. The make a call feature is so you can make an internal or external call, for internal calls you just type the number of the person you wish to call and for external calls you type a 9 first and then the number. The hold call feature is so that when you are on the phone to someone and you need them to wait whilst you find/do something, you just press the hold button to put them on hold and then press it again to talk to them. To transfer a call that comes to you incorrectly or if you think someone else would be a better person for them to talk to, you press the transfer call button and type the internal number of the person you are transferring them to. The loudspeaker function can be used if more than one person needs to listen to the call, press the button and the sound comes from the speaker instead of the receiver.
Unit 1 Assignment 1: Voice vs Data Cell Phones: Cell phones are a part of our everyday lives depending who you ask. The technology for them have come leaps and bounds that what anyone could imagine. Cell phones use to use a voice network only collecting waves from towers to transfer their voice communication. Sending one signal out and receiving one signal in. Now, though cell phones use both voice and data for their networks and it has been ongoing competition since then between carriers.
Executive summary: Metapath Software: September 1997 General: Metapath Software was formed in January 1995. Its purpose was to build a software product that allowed wireless carriers to see exactly what calls were on their networks at any point in time. They started out sluggish with only one contract, but after a new round of financing from Norwest and USVP, they landed an order worth $19 million with Sprint. Metapath now has to offers on its hands. One option is to be acquired by CallTech Communications, another firm that just recently went public, for $115 million.
According to Rainer & Turban (2008), “By 2007, Amazon had spent 12 years and some $2 billion building the infrastructure of its online store, which is among the biggest and most reliable in the world.” However, Amazon does not use but a small amount of its processing capacity at any one-time so the company decided to provide a series of computing, storage, and other services that make its infrastructure available to companies and individuals to help them run the technical and logistical parts of their businesses (Rainer & Turban, 2008). The three services are Simple Storage Service (S3), the Elastic Compute Cloud (EC2), and the Mechanical Turk. However, competition is steadily increasing with other Web sites such as Google and Microsoft for it to become the preferred first stop on the Web (Rainer & Turban, 2008). MySpace and YouTube, websites owned by Google, have become prime places for many people to gather online
Shang-wa’s CEO, John Lin, has been in the business since 1969. He entered into an exclusive contract with Lester (that is renewed annually) where Lester can sell Shang-wa capacitors in the United States as long as Lester has an annual purchase of $1 million wholesale. The partnership has been successful for many years. Two other manufacturers have been trying to acquire these firms. Transnational Electronics Corporation (TEC) has been after Shang-wa and Avral Electronics has been after Lester.
At Motorola, Cooper worked on many projects involving wireless communications, such as the first radio-controlled traffic-light system, which he patented in 1960, and the first handheld police radios, which were introduced in 1967. He later served as a vice president and director of research and development for the company. In 1973 he conceived of the first portable cellular phone and led the 10-year process of bringing it to market. Martin defied the industry's narrow vision of car phones and championed cellular telephony for personal, portable communications. Top management at Motorola was supportive of Cooper's mobile phone concept; investing $100 million between 1973 and 1993 before any revenues were realized.
In the past, people used mail and messengers to communicate from long distances. Then a man, Alexander Graham Bell, changed the way humans would communicate forever. Bell created the telephone which led to faster and easier ways to communicate. Nowadays, people still use telephones, and they also use cell phones which allow people to send messages, call people, search the Internet, play games, and so much more. Telephones and cell phones have changed the course of history for communication, by allowing an instant and easy way to communicate from a candlestick telephone, to modern advanced smart phones.
It was not until many years later in 1947, AT&T’s research arm, Bell Labs, introduced the idea of cellular communications (Web Corp.). Then in 1954, researchers with communications giant, Motorola, began work developing portable communication products. In 1967, one of those researchers, Martin Cooper, invented the portable handheld police radios used by the Chicago police department (Web Corp.). In “Biography: Martin Cooper,” George Leard writes that Cooper was born in Chicago, IL on December 26, 1928, and earned his Bachelor’s and Master’s degree in Electrical Engineering from the Illinois Institute of Technology. Thanks to Cooper’s invention, Motorola and Bell Labs were now in a race to incorporate the new technology into portable devices (Web Corp.).
