For question 1, I think the heap allocator allocates from higher addresses(at the end) to lower addresses(at the beginning).

and for question 2 and 3, I chose best fit for question 2 and none of the above for question 3, but not sure.

Need clear explanation for this kind of cases.



sizes between addresses = 1024, 64, 1024, 512, 1024, 128, 1024, 64, 1024
Question #1

If invoking the program as

memory 480,0,0,0
produced this output:

0 | 1024 | 1088 | 2112 | 2624 | 3648 | 3776 | 4800 | 4864 |

The 480-byte chunk was allocated at address 2144
would you conclude that the heap allocator allocates new chunks of RAM at the beginning (i. e., lower addresses) or at the end (i. e., higher addresses) of holes in memory? Why? To explain why just use a contraposition argument (e. g., if the heap allocator did X then Y would have happened, but instead Z happened).

Whatever the heap allocator does, this is what we assume it does for all subsequent questions.

Question #2

If invoking the program as

./memory 100,200,100,80
produces this output:

0 | 1024 | 1088 | 2112 | 2624 | 3648 | 3776 | 4800 | 4864 |

The 100-byte chunk was allocated at address 2524
The 200-byte chunk was allocated at address 2324
The 100-byte chunk was allocated at address 2224
The 80-byte chunk was allocated at address 3696
would you say that the heap allocator uses

first fit

best fit

worst fit

none of the above?

Question #3

If invoking the program as

./memory 40, 400, 80, 60
produces this output:

0 | 1024 | 1088 | 2112 | 2624 | 3648 | 3776 | 4800 | 4864 |

The 40-byte chunk was allocated at address 3736
The 400-byte chunk was allocated at address 2224
The 80-byte chunk was allocated at address 2144
The 60-byte chunk was allocated at address 4804
would you say that the heap allocator uses

first fit

best fit

worst fit

none of the above?

Question #4

After looking up some documentation, you find out that the heap allocator uses worst fit! What would the output of the memory program be when invoked as follows:

./memory 400, 100, 10, 10

Need asap assignment directions: think of an organization (business, religious institution, volunteer organization, sports team) with which you have been involved. imagine outfitting it with an it infrastructure. prepare a plan for what you would do to support outfitting it. draw a map of a network connecting all the individuals, give them pcs and printers, and lay out the design as best you can. the purpose is to begin working with these concepts, not to build a perfect network.

What is the function of compilers and interpreters? how does a compiler differ from an interpreter?
