Mobile Computing

 

What is mobile computing?

Mobile computing refers to the set of IT technologies, products, services and operational strategies and procedures that enable end users to access computation, information and related resources and capabilities while mobile. Mobile most commonly refers to access in motion, where the user is not restricted to a given geographic location.

Mobile may also refer to access in a fixed location via equipment that users can relocate as required but is stationary while in operation. This mode of operation is often called nomadic computing.

Today, mobile computing technology is everywhere. It has applications in business and consumer markets, industrial and entertainment industries, as well as many specialized vertical markets.

Desktop computers offer more hardware configuration capabilities and computational performance. However, the majority of end users prefer mobile devices. The key advantage of mobile computing is convenience, where users have access to information and computational resources anytime and anywhere.

How does mobile computing work?

Generally, a mobile computing system involves a mobile device, such as a laptop computer, tablet or smartphone, and a wireless network connection based on Wi-Fi or cellular wireless technology, such as 5G. Mobile devices typically can store data locally, and access to that data doesn't require a network connection.

Mobile computers typically accommodate access to both wireless and wired technology. Access to shared network resources, including mobile cloud-based resources, is essential given the collaborative nature of work today. Integrated, rechargeable batteries power mobile devices, and most can run on an alternating current (AC) power source when used from a fixed location.

In addition to laptops, tablets and smartphones, there are many mobile computing devices for vertical and specialized applications. These include devices for medical, surveillance, security, and telemetry and control uses.

Device selection is based on the application. For example, laptops are better suited for content creation, and tablets are often preferred for content consumption. Smartphones function as pocket-size computers and communication devices, but they have small screen sizes and screen-based keyboards.

Why is mobile computing used?

Mobile computing is used in most facets of life both in business and by consumers. It enables users to be untethered from a power source for periods of time. This is advantageous for traveling workers who want to stay connected to their work while on the move. It's also useful for remote workers who may not have all the connectivity and power options they have in an office setting.

Consumers use mobile computing in several ways, including the following:

• internet access
• mobile communications
• web browsing
• mobile applications
• entertainment streaming media

Mobile devices and apps can collect user data in various environments and contexts. Fitbit and smartwatches are examples of wearable technology that collect user data in novel contexts, including fitness and health settings.

Mobile computing also makes the internet of things (IoT) possible. The nontraditional computers, sensors and other devices that make up IoT are able to connect and communicate without direct human intervention.
