The cost value of a parent node includes the cost values of its child nodes. The cost parameter contains the estimated start cost and estimated total cost that are separated by two periods (..). Estimated start cost: the cost before the output phase starts. Estimated total cost: the ...
Availability: availability means any client that requests data gets a response even if some of the nodes are down. Partition Tolerance: a partition indicates a communication break between two nodes. Partition tolerance means the system continues to operate despite network partitions. The “2 of 3”...
Why are pointers necessary in any programming language? What is dynamic memory? How are LEDs used in green computing? Jarel wants to upgrade his memory and calls you for help. He knows that he's using DDR RAM and that his system clock is 133 MHz, but he isn't sure what type of DDR...
Cloud computing is a buzzword that means different things to different people. For some, it's just another way of describing IT (information technology) "outsourcing"; others use it to mean any computing service provided over the Internet or a similar network; and some define it as any bought...
Any type of web browsing involves a certain amount of two-way traffic between your computer (which is called a client) and the remote computers (servers) that host the pages you're looking at. Even though most of the data is flowingintoyour computer, a certain amount still has to flow ...

Usually, Machine Learning is ...
We therefore tested whether any of the putative adaptive (environmentally associated) genetic variation could be attributed to environmentally associated morphological variation throughout the study region. This could indicate both a heritable component to the associated body shape traits (as opposed to ...
