Mobile Computing LECTURE 2  Introduction ❖What is computing? Operation of computers (according to oxfords advance learner’s dictionary) ❖What is the mobile? That someone /something can move or be moved easily and quickly from place to place ❖Mobile Computing is an umbrella term used to describe technologies that enable people to access network services anyplace, anytime, and anywhere  What Is Mobile Computing? ❖Mobile Computing: is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device. ❖ It is free from having a connection with a fixed physical link. ❖It facilitates the users to move from one physical location to another during communication. ❖The key features of mobile computing are that the computing devices are portable and connected over a network Why is mobile computing used? ❖Mobile computing is used in most facets of life both in business and by consumers. ❖Consumers use mobile computing in several ways, including the following: ointernet access omobile communications oweb browsing omobile applications oentertainment  The elements of mobile computing 1. Mobile Communication. 2. Mobile Hardware. 3. Mobile Software.  1. Mobile Communication This refers to the communication infrastructure set in place, including wireless network infrastructure, protocols, data formats, bandwidths, and portals necessary to ensure seamless connectivity and communication. Mobile communication can be divided in the following four types: 1) Fixed and Wired 2) Fixed and Wireless 3) Mobile and Wired 4) Mobile and Wireless Types of mobile communications 1) Fixed and Wired: In Fixed and Wired configuration, the devices are fixed at a position, and they are connected through a physical link to communicate with other devices. For Example, Desktop Computer. 1) Fixed and Wireless: In Fixed and Wireless configuration, the devices are fixed at a position, and they are connected through a wireless link to make communication with other devices. For Example WiFi router Types of mobile communications 3) Mobile and Wired: In Mobile and Wired configuration, some devices are wired, and some are mobile. They altogether make communication with other devices. For Example, Laptops. 4) Mobile and Wireless: In Mobile and Wireless configuration, the devices can communicate with each other irrespective of their position. They can also connect to any network without the use of any wired device. For Example, WiFi Dongle Mobile and Wireless  2. Mobile Hardware ❖Mobile hardware consists of mobile devices or device components that can be used to receive or access the service of mobility. ❖ These devices are capable of operating in full-duplex. It means they can send and receive signals at the same time. ❖Examples of mobile hardware can be: smartphones, laptops, portable PCs, tablet PCs, Personal Digital Assistants  3. Mobile Software ❖The most important software component is the operating system, which is the brain of any computing system. ❖ For a laptop, this may be Windows, Linux or macOS, and for a smartphone, it may be Android or iOS. ❖The different applications running on a device are also part of the mobile software
