Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise

Transport services and protocols: provide communication between app processes running on different hosts. Send side: breaks app messages into segments, passes to network layer. RCV side: reassembles segments into messages, passes to app layer. Network layer: logical communication between host. Transport layer: local communication between processes -relies on enhances, network layer services. TCP: congestion control, flow control, connection setup.Multiplexing(sender): handle data from multiple Read More



Regression is a well-known statistical technique to model the predictive relationship between several independent variables (DVs) and one dependent variable. The objective is to find the best-fitting curve for a dependent variable in a multidimensional space, with each independent variable being a dimension. The curve could be a straight line, or it could be a nonlinear curve. The quality of fit of the curve to the data can be measured by a coefficient of correlation (r), which is the
