CASE 2

          In our daily lives, gadgets and other portable devices are very much needed. From the simple people up to the most powerful individual, these devices are very much essential. The most common gadget that everyone has is the cellphone or mobile phones. New models of cellphones now-a-days can be use for saving music, videos, playing different types of games, as a camera, and the most in demand type of mobile phones are those who have the function of a personal computer (the general type of a computer). But the usage of these types of handheld computer differs from the needs of different people.

            For a medical practitioner, their gadgets and other stuff must be related or somewhat relevant to their job. They also uses handheld computer just like a mobile phone, for them to contact people and for them to be contact. Handheld computers running Palm OS have been used in studies of urban academic emergency departments, to measure the timing of interactions between patients and emergency department staff. This replaces ineffective information gathering by the use of pen, paper and manual stopwatches. This specialized application enables the user to pick from a detailed list of activities done by the emergency department doctor and nurse. The same application also enables the user to time two activities simultaneously, as emergency department doctors often do. Activities of other care providers, including consulting physicians, radio technologists, phlebotomists, ECG technicians and respiratory therapists, also can be recorded. By this new technology, the health and wellness of the patients will be monitored by a simply touching and pressing buttons. This also made things inside the hospitals and clinics tense less and accurate.

            Inside a supermarket, a manager uses a specialized handheld computer that has this we called RFID or radio frequency identification. This is a type of bar code that emits a radio frequency, a computer monitoring system that tracks their products as they leave the shelves and when they are checked out. This inventory computer system is designed to keep automatic track of all inventory that the supermarket has. By this kind of device, the supermarkets can be able to analyze what products particular customers are buying (the same way online markets do) and keep better track of inventory as it moves throughout the store.

            The birth of computers, especially the birth of these handheld computers changed the whole lifestyle of every people. Handheld computers are portable extensions of personal computers, though they are not meant to replace the personal computer. They are mobile computing devices such as personal digital assistants, and smartphones. Some handheld computers are custom made to meet specific requirements such as extreme temperature resistance and environmental durability. Handheld computers are no longer just another personal gadget, as they have been deployed in the industry to solve real-world problems.
