To answer this question in the simplest terms: 1. A non CAS calculator can only find numeric (which might be in decimal, fractional or radical forms) results. 2. A CAS calculator can give you algebraic answers. For example, a CAS calculator can si...
Shallow copy is a bit-wise copy of an object. A new object is created that has an exact copy of the values in the original object. If any of the fields of the object are references to other objects, just the reference addresses are copied i.e., only the memory address is copied. deep copy copies all fields, and makes copies of dynamically allocated memory pointed to by the fields. A deep copy occurs when an object is copied along with the objects to which it refers.
with deep buffers vs. one with shallow buffers. To validate the importance of deep buffers at both the leaf and spine layers, one leaf switch is an Arista 7280SE switch which has 128MB of buffers per 10G port, while the other is the relatively shallow buffered Arista 7050 with a shared buffer of 9MB for all ports. At the spine layer, an Arista 7504 is used configured with 48 MB of buffer per 10G port The topology is shown in figure 2. To simulate shallow buffering across the board, the 7280SE and 7504 were manually configured so as to have 1 MB/10G port of buffering available. The deep-buffered network was oversubscribed at a ratio of 5.33:1, while the shallow-buffered network saw a lower oversubscription ratio of only 4:1. Even the shallow buffered switch setup used in the this test uses deeper buffers than most datacenter switches on the market today, which typically use dynamic buffering against a shared pool of 10-15MB for the entire switch.
