Operating System Structure
A key concept of operating systems is multiprogramming.
Goal of multiprogramming is to efficiently utilize all of the computing resources.
When a job issues an I/O request (e.g., open a file, read data from a file), it cannot continue until the request is fulfilled.
The CPU then becomes idle (the job is blocked on the request).
Operating System Structure
Basic idea of multiprogramming:
Keep multiple jobs in memory.
When one ....etc

Abstract :

Current trends in computing technologies are drifting towards distributed and parallel computing. These topologies emphasize on concurrent access schemes. Because of distributed computing, the use of shared resources like databases, memory, etc. is growing. Locking mechanisms can be used effectively to achieve high concurrency levels without corrupting the resources. There are a wide range of synchronization protocols, some providing strong consistency while others granting weak consistency. There is a trade-off between complexi ....etc

ABSTRACT
Cloud computers and multicore processors are two emerging classes of computational
hardware that have the potential to provide unprecedented compute capacity to the average
user. In order for the user to eectively exploit all of this computational ....etc

In neuropsychology it is commonly recognized that 70%
of all the sensory receptors in the brain are inputted from
the eyes. However, an important internal cognitive
function of the eyes as the perceptual browser of the
memory and the mind has not yet been recognized. This
keynote talk contrasts the cognitive mechanisms of the
eyes as both the sensor of the brain externally and the
browser of the mind internally. The key assertion is that
the eyes function as a bi-directional organ: a visual sensor
of the brain, and more impo ....etc

PIPELINED MULTUTHREADING TRANSFORMSATIONS AND SUPPORT MECHANISMS
In the future microprocessors, the chip multiprocessors will be the predominant type. But the improved application performance cannot be directly offered by the multiple on-chip cores. The applications are to be parallelized to execute simultaneously on the multiple cores and this is essential to their success. The DO ALL technique and similar independent multithreading techniques create the partially or fully independent threads in which the intercommunication among the ....etc

ROUTING PROTOCOLS WITH EFFICIENT FLOODING MECHANISMS
Routing Protocol With EfficientFlooding Mechanisms
Existing routing protocols employ efficient
flooding mechanisms to counter the
requirement of flooding.
– Preferred link-based routing (PLBR): On demand
– Optimized page link state routing (OLSR): Table-driven
These protocols require a minimum number
of retransmissions in order to flood the entire
network.
Preferred Link-Based RoutingProtocol (PLBR)
• Neighbor List (NL)
• Prefer ....etc
