Answer:

<em>a. fetch</em>

Explanation:

<em>The device collects a program command from its memory during the run cycle of the fetch. </em>

It then defines and performs the activities needed for that command.  The CPU continuously repeats the cycle of fetching, decoding, and executing a command while  the computer is switched on.

State one technique for overcoming external fragmentation in dynamic partitioning. Why is this technique of overcoming external
prisoha [69]

Compaction often gives solutions to the issues regarding external fragmentation.

One technique for overcoming external fragmentation in dynamic partitioning is

Compaction.

The reason why this technique of overcoming external fragmentation may be inefficient is because:

  • External fragmentation may need a lot of compaction and it is an expensive operation.

  • The use of contiguous allocation is often hard to fit processes into memory and also it is so difficult to grow or shrink the amount of memory allocated to a process.

  • Compaction only takes place when relocation is dynamic, and this also is expensive.

Compaction often shuffle memory notes or contents and then put or pile them up all in free memory and in one large block.

External fragmentation takes place when free memory is removed into small blocks.

inn [45]

Answer:

4

Explanation:

The loop is used to execute the part of code or statement again and again until a condition is not true.

syntax of for loop:

for(initialize; condition; increment/decrement){

   statement;

}  

in the question, the value of n is zero.

then, for loop check the condition k<2, initially the value of k is zero. so, the condition is true and execute the code n = 0 +2=2

Then, k is increment by 1. so, the value of k is 1.

then, again loop run and check the condition 1<2, it true. then n = 2+2=4.

then, k is increment by 1. so, the value of k is 2.

Then, again check the condition 2<2, condition false and program terminate the loop and finally print the value 4.
