two hosts A and B are communicating through a TCP connection. The maximum segment size (MSS) has been negotiated to be 1kbyte and the size of the receiver window of
B is 50 Kbytes. The network capacity is 1 MBps, the round trip time is 20ms, and the initial threshold of the Slow Start algorithm is set to 64 Kbytes. An expiration timer of 1s is engaged at the beginning of each transmission burst.
a. If the 4thtransmission round is completely lost, how long does it take to reach a congestion window of "maximum size" after the loss? Clearly illustrate your work(By just giving me a number will earn you NO points)
b. Now assume that the network has a capacity of 10 MBps. Find the Throughput of the session and the maximum efficiency (in the A--->B direction)

Answers

Answer 1

Therefore, at the beginning of the session when the congestion window is 64 Kbytes and the round trip time is 20 ms, the throughput is:

What is window?

a. The 4th transmission round was completely lost, so the congestion window will shrink to half its size, which is 32 Kbytes. Then, the congestion window will increase exponentially until it reaches the maximum size, which is 64 Kbytes.

The increase rate is given by the formula:

$CW_{i+1} = CW_i + MSS$

Where $CW_i$ is the congestion window size at the $i$th transmission round.

Therefore, to reach the maximum size, the congestion window needs to increase by 32 Kbytes (64 Kbytes - 32 Kbytes). With the MSS of 1 Kbyte, 32 transmission rounds are needed to reach the maximum size.

With an expiration timer of 1 second, it will take 32 seconds to reach the maximum size.

b. The throughput of the session can be calculated using the following formula:

$Throughput = \frac{CW * MSS}{RTT}$

Where $CW$ is the congestion window size and $RTT$ is the round trip time.

Therefore, at the beginning of the session when the congestion window is 64 Kbytes and the round trip time is 20 ms, the throughput

$Throughput = \frac{64 Kbytes * 1 Kbyte}{20 ms} = 3.2 Mbps$

The maximum efficiency in the A--->B direction is given by the following formula:

$Efficiency = \frac{Throughput}{Network Capacity}$

Therefore, with a network capacity of 10 Mbps, the maximum efficiency is:

$Efficiency = \frac{3.2 Mbps}{10 Mbps} = 0.32$

Answers

(a) One possible recurrence to solve this problem is:

Let f(i, j) be the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

f(i, j) = max(f(i, j-1), f(i, j-2) + A[j])

This recurrence calculates the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The subarray does not include the element at index j. In this case, the maximum sum is the same as the maximum sum ending at index j-1.

The subarray includes the element at index j, but skips the element at index j-1. In this case, the maximum sum is the sum of the elements ending at index j-2 plus the element at index j.

(b) Another possible recurrence to solve this problem is:

Let g(i, j) be the maximum sum of a contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

g(i, j) = max(g(i, j-1) + A[j], A[j])

This recurrence calculates the maximum sum of a contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The maximum sum of the subarray includes the element at index j. In this case, the maximum sum is the sum of the maximum sum ending at index j-1 plus the element at index j.

The maximum sum of the subarray does not include the element at index j. In this case, the maximum sum is simply the element at index j.

(c) To calculate the final overall answer, we can input the values 0 and n-1 into both recurrences, where n is the length of the array A. This will give us the maximum sum of a nearly contiguous subarray that starts at the beginning of the array and ends at the end of the array.

(d) To implement these recurrences using memoization, we can use a two-dimensional array to store the calculated values of f and g. The array can be initialized with values of 0 for all indices, and then we can fill in the values starting from the bottom right corner and working our way towards the top left corner.

(e) The running time of this algorithm would be O(n^2), because we need to calculate the values of f and g for every possible pair of indices i and j. This requires O(n^2) time in the worst case.

transmission often is called fixed wireless. group of answer choices microwave infrared coax fiber-optic

Answers

Signals are sent from one microwave station to another during microwave transmission, also known as fixed wireless (shown in Figure 8-1 on page 296). A dial-up modem cannot send data as quickly as a microwave, which can do it up to 4,500 times quicker.

Which alternative name for transmission data is appropriate?

It makes it possible for devices to move between and communicate with one another in point-to-point, point-to-multipoint, and multipoint-to-multipoint environments. Digital communications and transmission of data are other names for these processes.

Is fiber-optic fixed-wireless?

Internet access using fixed wireless is frequently used in rural areas and other places without fiber-optic infrastructure. Although portable and mobile systems can be employed in fixed sites, their efficiency and bandwidth are limited in comparison to stationary systems.

cyclomatic complexity of a code segment is an indicator of many independent paths are in the code. True or False

Answers

The amount of linearly independent pathways in a code segment is quantified as the cyclomatic complexity of that section.

How complicated is the following code cyclomatically?

The control flow graph will be used to calculate the code's cyclomatic complexity. Since there are seven shapes (nodes) and seven lines (edges) in the graph, its cyclomatic complexity is 7-7+2 = 2. Applying Cyclomatic Complexity: For developers and testers, figuring out the independent path executions has thus far proven to be quite useful.

What does cyclomatic program complexity mean?

A software statistic called cyclomatic complexity (CYC) is used to gauge how difficult a program is. It is a tally of the choices made in the source code. The code becomes increasingly difficult as the count increases.

(T/F) Desktop Management software requires managers to install software such as antivirus updates or application updates on client computers manually.

Answers

Managers must manually install software, such as antivirus updates or application updates, on client computers when using desktop management software. The answer is False.

What is Desktop Management software?

All computer systems inside a company are managed and secured by a desktop management programme, which is a complete tool. The management of other devices used by the organization, such as laptops and other computer devices, is also a part of "desktop" administration, despite the name.

Without requiring physical access to the endpoints, such as desktop computers or mobile devices, desktop management software enables IT teams to locate, manage, and control endpoints on both local and remote sites.

Keeping user PCs up to date can be difficult for IT managers, especially with the ongoing need to upgrade software to prevent security breaches.

A class-scope variable hidden by a block-scope variable can be accessed by preceding the variable name with the class name followed by:
1. ::
2. :
3. .
4. ->

Answers

The class name followed by:: can be used to access a class-scope variable that is hidden by a block-scope variable.

What is meant by class scope variable ?

A variable's scope can be categorized into one of three categories: 1) Class level scope (instance variables): All methods in a class have access to any variable declared within that class. It may occasionally be accessed outside the class depending on its access modifier (public or private).

The namespace where a class is declared is its scope. The class is global if it is declared in the global namespace. Every translation unit that makes use of ODR must specify the class.

Variables in Java are only used within the region in which they were created. Scope is what this is.

A "for" loop or other live structure can be programmed to run a specified number of times, and this is known as a loop variable in computer programming.

What is meant by loop function?

A loop in computer programming is a set of instructions that are repeatedly carried out until a particular condition is met. Typically, after completing a certain procedure, such as getting and modifying a piece of data, a condition, such as whether a counter has reached a specific number, is verified.

An R object (such as a list, vector, or matrix) is iterated over, a function is applied to each element of the object, the results are aggregated, and the results are returned.

An ongoing chunk of code can be repeated using a loop. For and while loops are the two main categories of loops.

Using the range() function, we can loop through a block of code a predetermined number of times. The return value of the range() function is a list of numbers that begins at zero by default, increases by one (by default), and terminates at a given value.
