Answer:
The comparison is based on memory organization schemes of contiguous memory allocation and paging with respect to External fragmentation, Internal fragmentation and Ability to share code across processes.
Explanation:
Memory organization schemes of contiguous memory allocation:
Contiguous memory allocation schemes suffers from external fragmentation. The reason is that address space is distributed contiguously and the holes and gaps keep growing when the old processes die and new processes are introduced. The variable size partition suffers from external fragmentation however the fixed size partitions do not suffer from external fragmentation. Contiguous memory allocation with variable size partitions does not encounter an internal fragmentation but with fixed size partitions suffers from internal fragmentation. Contiguous memory allocation does not support sharing code across processes. This is because the virtual memory segment of a process is not fragmented into non-contiguous fine grained blocks.
Paging:
Paging does not encounter external fragmentation as pages are of the fixed or equal size. So this reduces external fragmentation. However paging suffers from internal fragmentation. This is because a process can request more space or it can request for a less space. When page is allocated to the such a process that page is no longer utilized.This results in internal fragmentation because of the wastage of space even when the page has internal space but cannot be fully utilized. Paging allows to share code across processes.
Answer:
15.420 dB
Explanation:
the Gain (dB) of a transmission if the Maximum Data Rate is 1 Gbps and the Bandwidth =7000 MHz is 15.420 dB.
This question belongs to scratch programming. This programming language has various instructions to carry out various tasks. There are different types of repeat statement available. This statement or instruction allows the user / programmer to repeat certain line of statements to a number of times. Here, according to the question, we need to use “Repeat after me”
If you take a music note, the tempo, timing and pitch needs to be mentioned clearly and “:” represents that a particular note to be repeated only once.
Answer
You should maintain course and speed unless the give-way vessel fails to take action.
Explanation
In the water ways when two boats are approaching nearly and then they may come to collision the boat on the right is the one which is considered as the stand-on vessel and it should be given way by the other boat or vessel. On this situation it should maintain course and speed unless the give-way vessel fails to take action. If it fails to take action what you should do is, you should take action and move away from the vessel, do not go toward the vessel nor pass in front of it.
