In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.
Answer:
Bike Frame Flow Time
The value-added percentage of the flow time for this bike frame is:
= 46.
Explanation:
a) Data and Calculations:
Bike Frame Flow Time:
Setup time = 7 hours
Processing time = 6 hours
Storage time = 7 hours
Flow time of the bike frame = 13 hours (7 + 6)
Value-added percentage of the flow time for this bike frame = 6/13 * 100
= 46%
b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end. It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path. The storage time is not included in the flow time since it is not a manufacturing process.

Assume a TCP sender is continuously sending 1,090-byte segments. If a TCP receiver advertises a window size of 5,718 bytes, and with a link transmission rate 26 Mbps an end-to-end propagation delay of 22.1 ms, what is the utilization
Answer:
for the 5 segments, the utilization is 3.8%
Explanation:
Given the data in the question;
segment size = 1090 bytes
Receiver window size = 5,718 bytes
Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps
propagation delay = 22.1 ms
so,
Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms
we determine the total segments;
Total segments = Receiver window size / sender segment or segment size
we substitute
Total segments = 5718 bytes / 1090 bytes
Total segments = 5.24587 ≈ 5
Next is the throughput
Throughput = Segment / Round trip
Throughput = 1090 bytes / 44.2 ms
1byte = 8 bits and 1ms = 10⁻³ s
Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s
Throughput = 8720 bits / ( 44.2 × 10⁻³ s )
Throughput = 197.285 × 10³ bps
Now Utilization will be;
Utilization = Throughput / Bandwidth
we substitute
Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )
Utilization = 0.0076
Utilization is percentage will be ( 0.0076 × 100)% = 0.76%
∴ Over all utilization for the 5 segments will be;
⇒ 5 × 0.76% = 3.8%
Therefore, for the 5 segments, the utilization is 3.8%

i++;
j++;
}
// Print the disarray count
cout << "Pairs of disarray in given array:" << count;
/* ----- Solution Ends ----- */
return 0;

An engineer is configuring AMP for endpoints and wants to block certain files from executing. Which outbreak control method is used to accomplish this task
Question Completion with Options:
A. device flow correlation
B. simple detections
C. application blocking list
D. advanced custom detections
Answer:
The outbreak control method that is used to accomplish the task of configuring AMP for endpoints and to block certain files from executing is:
C. application blocking list
Explanation:
The application blocking list creates a list of application files, which the AMP continuously tracks and analyzes to compare the file activities with previous cyber attacks. Specifically, the AMP for Endpoints is a cloud-managed endpoint security solution, which provides a retrospective alert to prevent cyber-security threats, and rapidly detects, contains, and remediates malicious files on the endpoints.
continuously tracks and analyzes files and file activities across your systems, and compares these events to what preceded or happened in past attacks. If a file exhibits malicious behavior, the AMP provides you with a retrospective alert which enables you to stop a potential threat from succeeding.
Peter is a new business owner. Because Peter is on a strict budget, he uses an older Novell NetWare server. The NetWare server still relies on the legacy IPX/SPX network protocol suite. Peter needs to connect his server to the Internet. He decides to use a gateway instead of a router. What is the likely motive behind Peter's decision
The most likely motive of Peter's decision to use a gateway for connecting his serve to the internet is to get a wireless connection for the internet.
A gateway server is used to communicate to the internet service provider. It is used to receives the data. It helps to sends the data to the router in order to translate as well as distribute the wireless devices.
In the context, Peter who is on a strict budget uses gateway system to connect to the internet and he uses the older version of Novell NetWare server.

Answer:
"In inner for loop" is printed twice.
Answer: C. 2
Explanation:
Code:
int main()
{
int limit = 0;
for (int i =0; i>=limit; i-=2) {
for (int j = i; j <= 1; ++j){
cout << "In inner for loop" << endl;
}
cout << "In outer for loop" << endl;
}
return 0;
}
Output:
In inner for loop
In inner for loop
In outer for loop
The output "In inner for loop" print twice.
Thus, option (c) is correct.
In the given code example, the inner for loop has a condition j <= 1.
This condition means that the loop will execute as long as j is less than or equal to 1.
However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.
When i = 8, the inner loop has the condition j ≤ 1.
The loop will iterate as long as j is less than or equal to 1.
So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.
Therefore, the output print twice.
Thus, option (c) is correct.

Assume an RTT of 50ms, a packet size of 2KB, and an initial 2xRTT of handshaking before data is sent. A. If the bandwidth is 2Mbps, what is the Bandwidth-Delay Product (BDP)
Answer:
i) Total time = 2457.73 secs
ii) BDP = 0.01 Mbyte
Explanation:
Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits
Bandwidth : 2Mbps = 2,000,000 bits/sec
RTT = 50 ms = 0.050 secs
i) Determine total time required to transfer 500 kB
= Initial handshake + Time for transmission of all files + propagation delay
= 2 x RTT + Time for transmission + RTT /2
Total time = ( 2 * 0.05 ) + (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs
ii) Determine the Bandwidth-delay product
= data link capacity * RTT
= 2 Mbps * 50 ms = 100,000 = 0.01 MByte
what is incremental development and its importance in a project
Answer:
Incremental development in software engineering is a process methodology that emphasizes the virtue of taking small steps toward the goal.
Explanation:
Rather than delaying feedback until final delivery when time and resources have already been spent, incremental development ensures that teams can use feedback to make changes early and often.
The main importance of the Incremental model is that it divides the software development into submodules and each submodule is developed by following the software development life cycle process SDLC like Analysis, Design, Code, and Test.
Answer:
incremental development is any combination of both iterative design or iterative method and incremental build model for development
Explanation:
importance
Incremental development ensures that developers can make changes early on in the process rather than waiting until the end when the allotted time has run out and the money has been spent.
An incremental approach breaks the software development process down into small, manageable portions known as increments. Each increment builds on the previous version so that improvements are made step by step
