Define cloud computing and list the resources and services it provides. Describe how businesses use cloud computing. ANSWER: Student responses will vary, but should be drawn from the following information from the text. Cloud computing refers to an environment that provides resources and services accessed via the Internet. Resources include email messages, schedules, music, photos, videos, games, websites, programs, web apps, servers, storage, and more. Services include accessing software, storing files online, and configuring an environment of servers for optimal performance. That is, instead of accessing these resources and services locally, you access them on the cloud. For example, you use cloud computing capabilities when you store or access documents, photos, videos, and other media online; use programs and apps online (i.e., Page19 Name  : Clas  s: Dat  e: Module 03 - Computers and Mobile Devices email, productivity, games, etc.); and share ideas, opinions, and content with others online (i.e., online social networks). Businesses use cloud computing to more efÏciently manage resources, such as servers and programs, by shifting usage and consumption of these resources from a local environment to the Internet. For example, an employee working during the day in California could use computing resources located in an ofÏce in Paris that is closed for the evening. When the company uses the computing resources, it pays a fee that is based on the amount of computing time and other resources it consumes, much in the way that consumers pay utility companies for the amount of electricity used. Cloud computing allows a company to diversify its network and server infrastructure. Some cloud computing services automatically add more network and server capacity to a company’s website as demand for services of the website increases. The network and server capacity may be duplicated around the world so that, for example, an outage of a single server does not affect the company’s operations. 1 3-14 Cloud Computing LEARNINGOBJE VERR.DICO.15.3 - 3 CTIVES: TOPICS: Critical Thinking POINTS: REFERENCES: 96.

Describe the following game controllers: gamepad, joystick, wheel, dance pad, motion-sensing game controller, and balance board. ANSWER: Student responses will vary, but should be drawn from the following information from the text. Page20 Name  : Clas  s: Dat  e: Module 03 - Computers and Mobile Devices      POINTS: REFERENCES: LEARNINGOBJE CTIVES: TOPICS: A gamepad, which is held with both hands, controls the movement and actions of players or objects in video games or computer games. On the gamepad, users press buttons with their thumbs or move sticks in various directions to trigger events. Several gamepads can communicate with the game console simultaneously for multiplayer gaming. Users running flight and driving simulation software often use a joystick or wheel. A joystick is a handheld vertical lever, mounted on a base, that you move in different directions to control the actions of the simulated vehicle or player. The lever usually includes buttons, called triggers, that you press to initiate certain events. A wheel is a steering-wheel-type input device that users turn to simulate driving a car, truck, or other vehicle. Most wheels also include foot pedals for acceleration and braking actions. A dancepad is a flat, electronic device divided into panels that users press with their feet in response to instructions from a music video game. These games test the user’s ability to step on the correct panel at the correct time, following a pattern that is synchronized with the rhythm or beat of a song. A motion-sensinggamecontroller allows users to guide on-screen elements with air gestures, that is, by moving their body or a handheld input device through the air. Some motion-sensing game controllers are sold with a particular type of game; others are general purpose. Sports games, for example, use motion-sensing game controllers, such as baseball bats and golf clubs. With general-purpose motion-sensing game controllers, you simulate batting, golfing, and other actions with a universal handheld device or no device at all. Some motion-sensing game controllers also function as gamepads. Fitness games often communicate with a balanceboard, which is shaped like a weight scale and contains sensors that measure a game player’s balance and weight. 1 3-14 - 3-15 VERR.DICO.15.9 - 9 Critical Thinking 98.

Follow these precautions: POINTS: REFERENCES: • Take frequent breaks to exercise your hands and arms. • Do not rest your wrists on the edge of a desk. Instead, place a wrist rest between the keyboard and the edge of your desk. • Place the mouse at least six inches from the edge of the desk. In this position, your wrist is flat on the desk. • Minimize the number of times you switch between the mouse and the keyboard. • Keep your forearms and wrists level so that your wrists do not bend. • Avoid using the heel of your hand as a pivot point while typing or using the mouse. • Keep your shoulders, arms, hands, and wrists relaxed while you work. • Maintain good posture. • Stop working if you experience pain or fatigue. 1 3-35 Page21 Name  : Clas  s: Dat  e: Module 03 - Computers and Mobile Devices Health Concerns of Using Technology LEARNINGOBJE VERR.DICO.15.11 - 10 CTIVES: TOPICS: Critical Thinking 99.
