Are Mobile Devices is Used Computer System?

Give Examples of Other Personal Computing Devices

Today, the term computer no longer refers only to desktops used for office work system. Many of us carry computers with us everywhere we go. In fact, mobile devices have become the primary system computing devices for many people.

Mobile Devices

Mobile devices are portable, handheld computers used for business and entertainment and come in many different shapes and sizes from mobile smartphones to fitness monitors that you wear on your wrist. Some of these devices serve specialized functions, such as GPS navigation, while others, such as smartphones devices, are more general purpose devices.

Smartphones and Tablets

Mobile devices such as smartphones and tablets combine features such as Internet and email access, digital cameras, GPS and mapping tools, the ability to edit documents, and access to thousands of mobile apps. Mobile devices are useful when carrying a regular notebook computer isn’t practical. Once primarily the tool of business professionals, smartphones have become indispensable to the rest of us as well. Mobile devices are the fastest growing segment of personal computers.

Wearables and GPS

Computers worn on the body are known as wearables. These hands free computers are used for health monitoring, communications, military operations, and entertainment. Apple Watch is a general purpose wearable computer (Figure 1).

Originally built by the military, the Global Positioning System or GPS, consists of 24 satellites operating at all time, plus several spares (Figure 2). These satellites transmit signals that are picked up by a GPS receiver on the ground, to determine the receiver’s current location, time, and velocity through triangulation of the signals.

Since the mid-1990s, GPS devices have been available for civilian use. There are scientific applications for GPS technology, such as surveying, map making, selfnavigating robots, and clock synchronization used. GPS is used in automobiles, airplanes, and boats for navigation and tracking. Many mobile apps use GPS for navigation, location services, and just plain fun. For example, some apps used your location to determine what information to display, such as discounts, local weather, or nearby restaurant recommendations.

Video Game Systems and Simulations

A video game system is a computer designed primarily to play games. The first computer arcade video games were released in the early 1970s, and video game systems for the home soon followed. Magnavox released its Odyssey game console in 1972. It was programmed to play 12 different computer games. Atari released a home version of Pong for the 1975 holiday season. Sold exclusively through Sears, Pong was the hottest gift of the year. For many people, video game systems were the first computers they had in their homes.

Current eighth generation video game systems have highend processing and graphics capabilities, and the abilities to play movies and music, enable online game play, and browse the Internet. Game consoles such as Microsoft Xbox One and Sony PlayStation 4 have built-in hard drives, can play DVDs and Blu-rays, and display high definition video. Kinect for Xbox has motion and voice sensors that enable you to play certain games without holding a game controller a device used to interact with a video game. Nintendo’s Wii U is less powerful and less expensive than either the Xbox or the PlayStation. The Wii has motion sensing controllers that give players unique gameplay experiences and interactivity.

The Wii has reached out to nontraditional markets, such as senior citizens and families with young children, by offering such games as bowling, tennis, Wii Fit, and Brain Age.

Handheld video games, such as the Nintendo 3DS XL and 2DS and NVIDIA SHIELD Portable, enable you to take your games wherever you go. You can download and watch movies, view photos and listen to music, and chat with friends over cellular or Wi-Fi wireless networks system. Such systems include Internet capabilities, HD graphics, and a multicamera system that lets you take photos. The popularity of smartphones and tablets has reduced this market dramatically.

Video game systems aren’t just for entertainment. In healthcare, medical students use video game simulations to learn to be better doctors, simulations help stroke patient rehab to improve fine motor reflexes, and surgeons use simulations to practice intricate techniques. In other applications, pilots train on flight simulators, business students solve complex problems, and biology students dissect virtual frogs. Simulations enable you to immerse yourself in a situation that may not be safe or accessible otherwise.
