Peer-to-peer systems typically depend on untrusted and volatile computer systems for most of their resources. Trust is a social

phenomenon with technical consequences. Volatility (i.e. unpredictable availability) also is often due to human actions. Elaborate your answers to Question 1 by discussing the possible ways in which each of them is likely to differ according to the following attributes of the computers used
: (a) ownership

(b) geographic location

(c) network connectivity

(d) country or legal jurisdiction

maksim [4K]

Answer:

B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING

Explanation:

Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.

On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers

What category of predefined formulas in Excel contains the Boolean functions?
ololo11 [35]
The predefined formulas in Excel that contain the Boolean functions fall under the Logical Functions category. The Boolean functions consist of "AND", "OR", "XOR", "NOT", "IF", "IFERROR" and "IFNA".  When you need to use an Excel Function, you can type the function into the cell. You also need to add the arguments for the function in between brackets. If the function is complex or you are a beginner user, there is a function inputting tool which will help you choose which function you require.

A computing company is running a set of processes every day. Each process has its own start time and finish time, during which i
Helga [31]

Answer:

Above all else, let us show that this issue has the greedy choice property.

This implies that worldwide ideal arrangement can be gotten by choosing local ideal arrangements. Presently notice the following:

The global optimal solution of the issue requests us to track down the minimum number of times process_check module should be run.

It is likewise referenced that during each running interaction, process_check module should be called atleast once. Along these lines, the minimum possible number of process_check calls happens when process_check is made close to the quantity of the processes that are run.

Along these lines, we see that the global optimal solution is shaped by choosing optimal answer for the nearby advances.

Along these lines, the issue shows greedy choice property. Thus, we can utilize a greedy algorithm for this issue.

The greedy step in this calculation is to postpone the process_check as far as might be feasible. Thus, it should be run towards the finish of each interaction. So the following algorithm can be utilized:

Sort the cycles by utilizing the completion times.

Towards the finish of the 1st process in the arranged list, run the process_check module. Right now any process that is now running is removed the arranged rundown. The main interaction is additionally removed from the sorted list.

Now repeat stage 2, till all processes are finished.

In the above mentioned algorithm, the costliest advance is the step of sorting. By utilizing the optimal sorting algorithm, for example, merge sort, we can achieve it in O(n log n) asymptotic time.

Along these lines, this greedy algorithm additionally takes O(n log n) asymptotic time complexity.
