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.
Its to delete the files from the computer that you no longer want. Once its put in the recycling bin it stays there, then when you empty it, its off your computer and there is no way you can get those files back. This can also free-up some space from your computer since mega and giga bites are being removed from your computer.
<span>Correct Answer:
A. FireWire</span>
The feature of technology that allows this to happen is d. reduced latency.
Latency is the amount of time it takes for data to be transmitted in a network. Reduced latency therefore refers to a situation where data is transmitted with speed.
Reduced latency allows:
- better communication
- reduced lag and,
- better gaming
The machine in question is only able to quickly sound the alarm because it has low latency.
In conclusion, we can say that low latency enables the machine above to sound the alarm quickly which means that low latency is important to the safety of that environment.

Answer:
Informal information
Explanation:
The informal information system is employee based system design to meet personnel and vocational needs and to help in the solution of work-related problems. it also funnels information upward through indirect channels.
However, one of the most important reasons for why informal communication is critical to businesses is that it allows employees to give feedback to their superiors.
Thus, the informal or grapevine communication promotes social relationship among the participants. It helps to build up unity, integrity and solidarity among them and boosts up their morale. Grapevine or informal communication is faster than the formal communication.
