I am not sure if you are referring to the OSI 7 layer module, it refers to computer networking.

In computing, the Open Systems Interconnection model partitions a communication system into seven layers. They are the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer.
Nesting is the process of organizing information in layers. For an example, a loop in a program can contain another loop which can contain yet another loop. This is called nested loops.
affective computing!
"Distributed" or "grid" computing in general is a special type of parallel computing, it is advanced in the means of using distributed computing.
You don't have to specifically learn any programming language as long as you are familiar with them since cloud computing has several layers such as client, application, platform, infrastructure and server. If you are to be on the layer platform then yes you have to learn a specific language. Hosted EMR taught me of these ideas.
Cloud computing is better then normal grid computing as its cheaper to buy, use and maintain. Cloud computing can offer web hosting also which grid computing can not.
Cloud computing or grid computing depends on the task at hand. If you want to focus on a single enormous task, then go with grid computing. Cloud computing is more for multitasking.
Early computing was performed on a single processor. Makes use of a single cpu to execute one or more programs for each application Ex: A uni-processor
Soft computing differs from conventional (hard) computing in that, unlike hard computing, it is tolerant of imprecision, uncertainty, partial truth, and approximation. In effect, the role model for soft computing is the human mind.
The basic computing with the computer.
Business computing is done at work; personal computing is done at home.
Amiga Computing was created in 1988.
