Mobile Computing
Introduction
Mobile computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link. The main concept involves mobile communication, mobile hardware, and mobile software.
Mobile Communication
Mobile communication involves the use of wireless communications to connect to different networks around the world. This can be achieved through various mediums such as satellite systems, wireless network systems and cellular systems. The use of wireless networks in mobile computing is rapidly increasing with technologies like Wi-Fi, Wi-Max and others.
Mobile Hardware
Mobile hardware includes mobile devices or device components that receive or access the service of mobility. They include devices like mobile phones, smartphones, tablet PCs, laptops, personal digital assistants (PDAs), and other similar devices. These devices are equipped with RFID (Radio Frequency Identification) tags that help in identification and detection.
Mobile Software
Mobile software is the actual program that runs on the mobile hardware. It deals with the characteristics and requirements of mobile applications. This is the engine of the mobile device. In other words, mobile software controls the mobile hardware and makes it function. Examples of mobile software include operating systems like Android, iOS, Windows Phone, etc.
Mobile Operating Systems
Mobile operating systems are the platforms that drive mobile devices. The most popular mobile operating systems are Android, iOS, and Windows Phone. These platforms are responsible for regulating the functions of the mobile devices and they allow users to add applications or software to the device to increase its functionality.
Mobile Applications
Mobile applications, also known as mobile apps, are software applications designed to run on mobile devices. These applications are built for various platforms like Android, iOS, and Windows Phone. Mobile apps are what make a smartphone "smart". They provide enhanced functionality to devices, in areas such as games, factory automation, GPS and location-based services, banking, order-tracking, ticket purchases, mobile medical apps, etc.
Mobile Security
Mobile security is a crucial aspect in mobile computing. It is primarily concerned with the security of personal and business information stored and shared through a mobile device. Mobile security has become increasingly important in mobile computing due to the increasing number of threats and attacks on mobile networks.
Mobile Commerce
Mobile commerce, also known as m-commerce, involves the use of mobile devices to conduct business transactions. This can be done through mobile applications or browsers, allowing users to shop online, make payments, or do banking activities.
Conclusion
Mobile computing has revolutionized the way we interact with technology and access information. It has brought about a new era of connectivity, enabling us to communicate and conduct business from anywhere in the world. However, with these advancements come challenges, particularly in the area of security. As mobile computing continues to evolve, it is important to stay informed and vigilant in order to maximize its benefits and minimize its risks.
