Short Answer

1. – What is a computer?
   A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and store the results for future use.
   – What is the information processing cycle?
   Some people refer to the series of input, process, output, and storage activities as the information processing cycle.
2. – Describe two health risks posed by computers.
   Prolonged or improper computer use can lead to injuries or disorders of the hands, wrists, elbows, eyes, neck, and back. Individuals suffering from technology overload feel distressed when deprived of computers and mobile devices.
   – How might computers have a negative effect on the environment?
   Computer manufacturing processes and computer waste are depleting natural resources and polluting the environment. When computers are discarded in landfills, they can release toxic materials and potentially dangerous levels of lead, mercury, and flame retardants.
3. – What is a Web application?
   A Web application is a Web site that allows users to access and interact with software from any computer or device that is connected to the Internet. Examples of software available as Web applications include those that allow you to send and receive e-mail messages, prepare your taxes, organize digital photos, create documents, and play games.
   – What are some features of a Web 2.0 site?
   Provide a means for users to share personal information (such as social networking Web sites), allow users to modify the Web site contents (such as some blogs), and/or have software built into the site for users to access (such as Web applications).
4. – What are seven categories of computers?
   Personal computers (desktop), mobile computers and mobile devices, game consoles, servers, mainframes, supercomputers, and embedded computers.
   – What determines how a computer is categorized?

5. – How do Web sites benefit individuals’ health care?
   Many Web sites provide up-to-date medical, fitness, nutrition, or exercise information. These Web sites also maintain lists of doctors and dentists to help you find the one that suits your needs. They have chat rooms, so that you can talk to others diagnosed with similar conditions. Some Web sites even allow you to order prescriptions online.
   – How does telesurgery differ from telemedicine?
   Telesurgery, also called remote surgery, a surgeon performs an operation on a patient who is not located in the same physical room as the surgeon. Telesurgery enables surgeons to direct robots to perform an operation via computers connected to a high-speed network.
   Through telemedicine, health-care professionals in separate locations conduct live conferences on the computer. For example, a doctor at one location can have a conference with a doctor at another location to discuss a bone X-ray. Live images of each doctor, along with the X-ray, are displayed on each doctor’s computer.
