Solution

Pervasive computing refers to the integration of microprocessors into everyday objects and environments, allowing these devices to communicate and perform tasks autonomously. This concept is central to the Internet of Things (IoT) and mobile computing. a) Use of virtual machines : Virtual machines relate to cloud computing, not specifically pervasive computing. b) Constant network connectivity : While connectivity is important, the primary feature of pervasive computing is device integration into the environment. d) Cloud-based data storage : Cloud storage is an aspect of mobile computing but not the defining feature of pervasive computing. e) Large-scale data processing : This refers more to big data analytics than to pervasive computing.
