Suppose two TCP connections share a path through a router R. The router's queue size is six segments while each connection has a stable congestion window of three segments each. No congestion control is used by these connections, A third TCP connection is now attempted through R. The third connection does not use congestion control either. Describe a scenario in which, for at least a while, the third connection gets none of the available bandwidth while the first two connections continue to occupy 50% of the bandwidth. How does congestion avoidance on the part of the first two connections helps avoiding this particular scenario?
Answers
The paragraph describes a scenario where two TCP connections are already occupying 100% of the router's queue capacity.
What is the scenario described in the paragraph?In this scenario, the first two TCP connections are already occupying 100% of the router's queue capacity, with each connection having a stable congestion window of three segments.
When the third connection is attempted, it also starts sending data without congestion control.
As a result, the router's queue becomes overwhelmed with segments from all three connections, causing packet drops and triggering the TCP congestion control mechanism in the first two connections.
As the first two connections implement congestion avoidance, they start reducing their sending rates, resulting in a decrease in their congestion windows.
This decrease in the congestion window of the first two connections frees up some space in the router's queue, allowing the third connection to send some of its packets through the router.
However, if the third connection continues to send without congestion control, it may cause the router's queue to become congested again, leading to packet drops and triggering congestion control in all three connections.
Therefore, congestion avoidance on the part of the first two connections is critical in avoiding this scenario.
By implementing congestion avoidance, the first two connections can help prevent the router's queue from becoming congested and ensure that the available bandwidth is shared fairly among all connections.
This allows the third connection to also send data through the router without causing packet drops or triggering congestion control in any of the connections.

I need help with this question.
Answers
Explanation:
Whilst it is impractical to convert all the numbers to binary, I will explain how binary works to you.
Binary is usually composed of eight bits, each representing a different number.
0000 0000
Each 0 represents a column in an 8-bit binary number. The far-right column starts at 1 and doubles each time you change to the left column.
128 64 32 16 8 4 2 1
0 0 0 0 0 0 0 0
A number 1 means that there is a number in that column whereas a 0 means there isn't, like the normal "0 means off and 1 means on" system. When there is a 1 in every column:
1 1 1 1 1 1 1 1
There can be a maximum value of 255.
For example, the number 79 would be represented in binary as:
128 64 32 16 8 4 2 1
0 1 0 0 1 1 1 1
64 + 8 + 4 + 2 + 1 = 79

Answers
A plain-text résumé is an electronic version of a résumé that is stripped of all formatting and styling elements, including fonts, colors, and graphics. It is a highly popular format for e-mailing and online submission because it can be easily pasted into a text box or an online form, allowing employers to quickly and efficiently scan through the content without any distractions.
Plain-text résumés are also preferred by employers because they are more compatible with various systems and devices, making them more accessible to hiring managers and recruiters who use different software and platforms. Additionally, a plain-text résumé is easier to read and parse by applicant tracking systems (ATS), which are widely used by companies to sort through thousands of applications automatically.
However, it is important to note that while plain-text résumés are highly functional and practical, they lack the visual appeal and creativity of a well-designed résumé. Therefore, job seekers should use plain-text résumés only when specifically requested or when applying to positions that require a standardized format. Otherwise, it is recommended to use a visually appealing and professionally designed résumé that showcases one's skills, experiences, and personality.

what is the key difference between email and instant messaging
Answers
The key difference between email and instant messaging lies in their modes of communication and usage.
Email is an asynchronous form of communication where messages are sent and received at different times. It allows for longer, more formal messages and attachments. Email messages can be composed offline and sent when a connection is established. It is commonly used for professional or formal correspondence, providing a paper trail of communication.
On the other hand, instant messaging is a synchronous form of communication where messages are sent and received instantly in real-time. It enables quick, informal conversations with short messages. Instant messaging typically occurs within dedicated applications or platforms and often supports additional features like group chats, file sharing, and video calls. It is commonly used for casual or immediate communication, allowing for faster and more interactive conversations.
While both email and instant messaging serve communication purposes, their distinct characteristics make them suitable for different contexts and preferences.

Here's a breakdown of the components of the VLOOKUP formula:
EmployeeNumber: This is the value you want to look up, which is the employee number entered in the formula.
EmployeeDataRange: This is the range of cells that contains the employee data, including the employee number, name, department, and years on the job. Make sure this range includes the employee number column as the first column.
ColumnIndex: This is the column number in the EmployeeDataRange from which you want to retrieve the data. For example, if the Name is in the second column, the Department is in the third column, and the Years on the Job is in the fourth column, you would use 2, 3, or 4 as the ColumnIndex value, respectively.
False: This specifies an exact match for the employee number. It ensures that the formula only returns data when there's an exact match for the employee number.
By using the VLOOKUP formula with the appropriate parameters, you can retrieve the Name, Department, and Years on the Job of an employee based on their employee number. Simply replace EmployeeNumber with the cell reference that contains the employee number, EmployeeDataRange with the range of cells containing the employee data, and ColumnIndex with the corresponding column number for each desired attribute.

Determine the correct amounts for items A through O.
Answers
A: Purchases of direct materials
Since the beginning and ending direct materials inventory values are given, we can calculate the direct materials purchased by using the following formula:
Purchases of direct materials = Beginning direct materials + Direct materials used - Ending direct materials
A = $50,250 + $91,385 - $34,165
A = $107,470
B: Direct labor
The direct labor value for 12/31/20 is given as $162,000. There is no direct labor value for 12/31/19, so we cannot determine the exact value. We'll leave it as it is.
C: Total manufacturing costs
The total manufacturing costs consist of direct materials used, direct labor, and manufacturing overhead.
C = Direct materials used + Direct labor + Manufacturing overhead
C = $91,385 + $162,000 + $115,325
C = $368,710
D: Ending finished goods inventory
The ending finished goods inventory value for 12/31/21 is given as 39,550. There is no value for 12/31/20, so we cannot determine the exact value. We'll leave it as it is.
E: Net income
The net income values for 12/31/19 and 12/31/20 are given as $46,250 and $39,000, respectively. There is no net income value for 12/31/21, so we cannot determine the exact value. We'll leave it as it is.
F: Beginning direct materials

G: Manufacturing overhead
The manufacturing overhead value for 12/31/20 is given as $127,145. There is no value for 12/31/19, so we cannot determine the exact value. We'll leave it as it is.
H: Costs of goods manufactured
The costs of goods manufactured equal the total manufacturing costs plus the beginning work-in-process inventory minus the ending work-in-process inventory.
Costs of goods manufactured = Total manufacturing costs + Beginning work-in-process inventory - Ending work-in-process inventory
H = $368,710 + $21,985 - $29,635
H = $361,060
I: Beginning finished goods inventory
The beginning finished goods inventory value for 12/31/19 is given as $37,000. There is no value for 12/31/20, so we cannot determine the exact value. We'll leave it as it is.
J: Selling and Administrative Expenses
The selling and administrative expenses value for 12/31/19 is given as $135,950. There is no value for 12/31/20, so we cannot determine the exact value. We'll leave it as it is.

Answers
To determine the exact amount the Walker family will have to pay and the insurance company's portion, it is necessary to consult the details of their insurance policy, specifically the coverage limits, deductibles, and any applicable terms and conditions.
Based on the information provided, the answer to question 3 (total cost to repair the damage) is missing, so we cannot provide an exact amount. However, we can address question 4 regarding how much of the cost the Walker family will have to pay and how much will be covered by the insurance company.
Typically, in cases of home insurance, there are deductibles and coverage limits that determine the portion of the repair costs to be paid by the policyholder and the insurance company. The deductible is the amount the insured person must pay out of pocket before the insurance coverage kicks in.
Let's assume the total cost to repair the roof damage is $5,000. If the Walker family has a deductible of $1,000, they would be responsible for paying that amount themselves. The insurance company would cover the remaining $4,000.
It's important to note that the actual costs and coverage details may vary depending on the specific insurance policy the Walker family has, including the deductible, policy limits, and any endorsements or exclusions.

Answer:
35.80
Explanation:
If Hugh bought 3 magazines that would equal 11.85, and 47.65-11.85=35.80.
I hope this helps
Answer:
since m = 3, therefore 3.95m = 3.95×3 = 11.85
this implies that 11.85 +8.95b = 47.65
this means 8.95b = 47.65 - 11.85 = 35.80
therefore b = 35.80 ÷ 8.9 = 4
since b = 4 ,this means Hugh bought 4 books
