Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is the planning stage. Because the planning stage represents the development of documents that provide the basis for acquiring the resources and for developing the requirement document. at this stage, you plan about what you are going to develop and how to develop it. At this stage, you come out mainly with two documents i.e. project proposal and requirement document.
Other options are not correct because:
In the project management, after planning, you will start designing the product, and after designing you start developing the product, and at the implementation stage, you implement or deploy the product to the customer or to the client. The requirement document that is developed at the planning stage can be used in the later stages of the project.

Explanation:
To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.
The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:
Improved Resource Usage:
A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.
Improved throughput:
Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.
Lower/shorter waiting time:
Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.
The characteristics listed above are critical to a system's performance.
Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.
Answer:
1. First of all check the laptops warranty
2.Estimate the cost of replacing the motherboard.
3. Take a picture of the old motherboard and make diagram of board and analyze the wires working as well
4. Estimate the cost of new laptop and compare it with new motherboard
5. If cost is less than new laptop then find out the services manually to replace the motherboard .
Digital is the best computer to awnser this question ok dude poop is good on plates I am just doing this to finish
Answer:
You can simplify the problem down by recognizing that you just need to keep track of the integers you've seen in array that your given. You also need to account for edge cases for when the array is empty or the value you get would be greater than your max allowed value. Finally, you need to ensure O(n) complexity, you can't keep looping for every value you come across. This is where the boolean array comes in handy. See below -
public static int solution(int[] A)
{
int min = 1;
int max = 100000;
boolean[] vals = new boolean[max+1];
if(A.length == 0)
return min;
//mark the vals array with the integers we have seen in the A[]
for(int i = 0; i < A.length; i++)
{
if(A[i] < max + 1)
vals[A[i]] = true;
}
//start at our min val and loop until we come across a value we have not seen in A[]
for (int i = 1; i < max; i++)
{
if(vals[i] && min == i)
min++;
else if(!vals[i])
break;
}
if(min > max)
return max;
return min;
}
