You must be aware of a cluster of different technologies related to networks.

Area Characteristics
mobile computing Mobile computing is human–computer interaction by which a computer is expected to be transported during normal usage, which allows for transmission of data, voice and video [2]
  • Portability: Devices/nodes connected within the mobile computing system should facilitate mobility. These devices may have limited device capabilities and limited power supply, but should have a sufficient processing capability and physical portability to operate in a movable environment.
  • Connectivity: This defines the quality of service (QoS) of the networka group or system of interconnected people or things. connectivity. In a mobile computing system, the networka group or system of interconnected people or things. availability is expected to be maintained at a high level with the minimal amount of lag/downtime without being affected by the mobility of the connected nodes.
  • Interactivity: The nodes belonging to a mobile computing system are connected with one another to communicate and collaborate through active transactions of data.
  • Individuality: A portable device or a mobile node connected to a mobile networka group or system of interconnected people or things. often denote an individual; a mobile computing system should be able to adopt the technology to cater the individual needs and also to obtain contextual information of each node.
ubiquitous computing Ubiquitous computing is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. [3]
peer-2-peer networka group or system of interconnected people or things.

Peer-to-peer (P2P) computing or networking is:

  • a distributed application architecture
  • which partitions tasks or workloads between peers
  • peers are equally privileged
  • peers are equipotent
  • peers form a peer-to-peer networka group or system of interconnected people or things. of nodes
  • peers make a portion of their resources, such as processing power, disk storage or networka group or system of interconnected people or things. bandwidth, directly available to other networka group or system of interconnected people or things. participants, without the need for central coordination by servers or stable hosts.
  • peers are both suppliers and consumers of resource. [4]
grid computing
  • grid computing is the collection of computer resources
  • from multiple locations to reach a common goal
  • the grid can be thought of as a distributed system
  • with non-interactive workloads
  • involve a large numberA unit of abstract mathematical system subject to the laws of arithmetic. of files.[5]
