A system consumed 0.4 seconds of processor time, 0.3 seconds accessing the network, and 0.5 seconds accessing the disk drive to execute the task. Where is the bottleneck in this network

the disk drive

Explanation:

A bottle neck in a network is the condition through which the data flows becomes limited by the network of the computer system. It occurs in the user network or within the servers where there are contention for any internal server resources.

In the context, a system that consumes 0.4 seconds for the processor time and time 0.3 seconds for accessing the network. The system also takes 0.5 seconds for accessing disk drive for executing the task. So the bottle neck in this system is the disk drive.

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.
