Consider a client and a web server directly connected by a link of rate R. Supposed the client wants to retrieve an object of size 15*S, where Sis the maximum segment size (MSS). Assume the round-trip time betweenthe client and the server is a constant RTT. Ignoring protocol headers, determine the time to retrieve the object (including TCP establishment) and explain your answer when: a. 4S/R > S/R + RTT > 2S/R
b. S/R + RTT > 4S/R
c. S/R > RTT

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 answer is false i just took the test
