Which is the most likely reason why scientists change a model? a)the public wants to understand a concept more easily. b)students need illustrated models in a study guide. c)new discoveries makes the current model inaccurate. d)current models may be uninteresting.

C.) New discoveries make the current model inaccurate. Since science is all about observation and experimentation, it is logical that whenever new findings are gathered, scientific models must be modified to adapt to the information. As new ideas and concepts are uncovered, models should be updated to make them correct.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

explanation:

the difference is right there dont you see it
