Question

Match the pairs in the following questions by writing the corresponding letters only.
$$\begin{array}{|ll|ll|}\hline \text{(a)}  &  \text{Buddy system} & \text{(p)} & \text{Run time type specification} \\ \text{(b)}  &  \text{Interpretation} & \text{(q)} & \text{Segmentation} \\ \text{(c)}  &  \text{Pointer type} & \text{(r)} & \text{Memory allocation} \\ \text{(d)}  &  \text{Virtual memory} & \text{(s)} & \text{Garbage collection} \\\hline \end{array}$$

Comments

what is interpretation in this question?

---

Buddy system - The buddy memory allocation technique is a memory allocation algorithm that divides memory into partitions to try to satisfy a memory request as suitably as possible. This system makes use of splitting memory into halves to try to give a best fit.

Interpretation - Run-time (pretty obvious)

Pointer type - Garbage collector dereference the dangling pointers

Virtual memory - Segmentation

@arch See definition from Galvin.

interpretation:  A methodology that allows a pro-
gram in computer language to be either executed
in its high-level form or translated to an interme-
diate form rather than being compiled to native
code.

Such programs are executed directly at run-time (execution time) without requiring to previously compile them into machine instructions.

Answer 1

$(a) - (r), (b) - (p), (c) - (s), (d) - (q)$

Comments

How virtual memory and segmentation are related? Both are different memory allocation techniques.

@Arjun sir.How can we relate pointer to garbage collection. If we have pointers like in C,but we dont have garbage collection.

In java we have garbage collection but not pointers.

So.what does this match specify?

---

languages like c++ have garbage collector
