We need layers in the network model because each layer focuses on its own responsibilities. Each layer can rely on the headers for processing instructions and does not need to know the meaning of the data from the last layer. Why is Nginx called a “reverse” proxy? The diagram below shows...
Guacamole may also be a reference to a famous joke which made the rounds about 15 years ago, where somebody had compared the 7 layers of the OSI network model to Taco Bell's 7-layer burrito. Guacamole was the 5th layer, which lends credence to this idea. It's still available on the ...
You encapsulate your letter into an envelop and the envelop, in turn, is encapsulated within source and destination addresses (much like the layers of the OSI model). There are fields in destination address of a letter that map to layer 3, layer 3 and layer 2 principals. The ZIP code is...

The calculated step-like stress-strain response that exhibits the feature of "graceful failure" in these randomly staggered laminates is obtained. Its formation can be roughly explained as the result of superposition of propagation of interface failure involving different overlapping lengths. Results ...

Why do we need so many layers in the OSI model? The diagram below shows how data is encapsulated and de-encapsulated when transmitting over the network. Step 1: When Device A sends data to Device B over the network via the HTTP protocol, it is first added an HTTP header at the ...
