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 network connectivity. In a mobile computing system, the network 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 network 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 network |
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 network of nodes
- peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network 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 number of files.[5]
