Question

essay on mobile computing

Answer 1

Mobile computing is human–computer interaction by which a computer is expected to be transported during normal usage, which allows for transmission of data, voice and video. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.



Principles of Mobile ComputingEdit

Portability: Facilitates movement of device(s) within the mobile computing environment.Connectivity: Ability to continuously stay connected with minimal amount of lag/downtime, without being affected by movements of the connected nodesSocial Interactivity: Maintaining the connectivity to collaborate with other users, at least within the same environment.Individuality: Adapting the technology to suit individual needs.

or

Portability: Devices/nodes connected within the mobile computing system should facilitate mobility. These devices may have limited device capabilities and limited power supply, but should have a sufficient processing capability and physical portability to operate in a movable environment.Connectivity: This defines the quality of service (QoS) of the network connectivity. In a mobile computing system, the network availability is expected to be maintained at a high level with the minimal amount of lag/downtime without being affected by the mobility of the connected nodes.Interactivity: The nodes belonging to a mobile computing system are connected with one another to communicate and collaborate through active transactions of data.Individuality: A portable device or a mobile node connected to a mobile network often denote an individual; a mobile computing system should be able to adopt the technology to cater the individual needs and also to obtain contextual information of each node.

Answer 2

Mobile Computing and Social Networking Compare and contrast monitoring of patient vital signs using mobile computing technology to in-patient visits to the doctor’s office or hospital. 
 As most of the patients carry mobile devices, they understand the ability to monitor vital signs using mobile computing in real-time and saves time instead of visiting a doctor’s office or hospital. Patients can understand vital signs, and they can visit the doctor at a person’s discretion or otherwise can take over the counter medication.
 Although doctor’s office or hospitals provide patients with instructions, they are not able to provide patients with accurate information about the disease but using mobile computing technology, patients can get …show more content… 
 As the patient’s data saved on the server, the physicians and nurses can view the data from mobile devices, which helps to increase their efficiency.
 Using the mobile computing technology, doctors can view a patient’s lab results real-time and analyze the patient’s condition instead of using the traditional method of receiving the lab results. 
 Physicians can view the patient’s medical history and records from anywhere in the world, which allows to take care of the patients more proficiently.
 Using mobile computing devices in the hospital reduces the space in the hospitals, can accommodate more patients and helps to reduce the cost on the extra space. 
 Mobile computing devices creates less clutter and lower costs while delivering more services more efficiently.
 Mobile computing technology minimizes paperwork and reduces errors. All the data regarding the patient’s medical and billing records stored in the database servers. 
 Mobile devices consume less energy than the desktops, workstations that help to save on the electricity bills.
 Mobile devices have more functionality and connectivity than traditional phones.
