WHEN USING HANDHELD COMPUTER. . . .

          A mobile device is known as handheld computer that is a pocket-sized computing device, typically having a display screen with touch input and/or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are often combined into a touch-screen interface. Smart phones and PDAs are popular amongst those who require the assistance and convenience of certain aspects of a conventional computer, in environments where carrying one would not be practical.

          The two professionals that I would put forward a theory about how that person might use a hand held computer in their work were a newspaper reporter and a manager in a supermarket.

          A newspaper reporter gather and analyze facts about current events through interviews, investigations, or observations and write stories describing the events, background, meaning, and effects.  They are assigned breaking news developments such as disasters, crime, and human interest.  They take notes or use a tape recorder while covering a story.  They check reference materials such as books, news files, and public records including criminal and civil court files for additional relevant facts.  Basic tasks of reporters involve viewing events objectively, reporting them accurately, and explaining their significance. This person might use a handheld computer in their work by making their news report quickly, taking pictures of evidences to their story, and easy to carry because of its size, small. It would help them to work simply that makes them more interested for their work, help them be more organized and to more efficiently process newspaper ad sales. It helps them to record the details easily, browse in a web quickly and take pictures or videos that will provide them for proving or for some evidences. Using this handheld computer for a newspaper reporter they can make their feature story and newspaper pictures easy, no hurry for editing and just send their finished story to their publishing company. Also, using handheld computer is a great potential resource for them because of its versatility and portability.

          Manager in a supermarket is the one who is in-charge in supermarket that sells food, drink, products for cleaning the house etc. He/she supervise of the workers within the supermarket day to day.   The manager might use the handheld computer in their work  by able to make telephone calls, make payments and can use it to store all information that they have in their briefcases, and the device is assisted by wireless networking, where it is an essential step in making electronic document exchange, electronic communication and electronic commerce. It helps them make their work easier and efficient like what a newspaper reporter does.  The device is a small portable computer with a smart card and communications device that can replace a cash, cheque book, passport, keys, diary, phone/pager and maps. Using the handheld computer, the manager could send e-mail and to access information services and data networks. Handheld computer is truly a personal machine that for instance, it contains sensitive information or store the owner’s private keys or electronic money. The device helps the manager to be more organized with his/her work which can access to their business data and applications.
