We Have Numbers Of Free Samples

1. A station running TCP/IP needs to transfer a file to a host. The file contains 1024 bytes. How many bytes, including all of the TCP/IP overhead, would be sent, assuming a payload size of 128 bytes and both systems are running IPv4? (Also assume that the three-way handshake and window size negotiation have been completed and that no errors occur during transmission.)

1. what is the protocol overhead (stated as a percentage)?
2. perform the same calculation, this time assuming that both clients are using IPv6.

Solution 1

1. for calculation of the protocol overhead

Now with assumption of IPv4 protocol in use

Given:

FIle Size→1024 Bytes
Payload→128 Bytes

Now as we know that TCP and IPv4 headers are of size (20 + 20) Bytes

As payload is of 128 so file size must be divided in 8 equal parts

Hence one segment has

While transmission complete segment size would be

one segment= 128 Bytes+40 Bytes
one segment= 168 Bytes

So total data would be

data= 168 Bytes*8=1344 Bytes

Now we can calculate overhead percentage as

2. now in case if IPv6 protocol is used

Given:

FIle Size→1024 Bytes
Payload→128 Bytes

Now as we know that TCP and IPv6 headers are of size (20 + 40) Bytes

As payload is of 128 so file size must be divided in 8 equal parts

Hence one segment has

1024/8 Bytes=128

While transmission complete segment size would be

one segment= 128 Bytes+60 Bytes
one segment= 188 Bytes

So total data would be

data= 188 Bytes*8=1504 Bytes

Now we can calculate overhead percentage as

2. IP is a connection-less protocol, whereas TCP is connection-oriented. How can these two protocols coexist in the same protocol stack? Solution 2

Connectionless implies that no exertion is made to start a devoted start to finish association, on other hand Connection-Oriented implies that when gadgets convey, they do handshaking to set up a start to finish connection.

IP is a case of the Connectionless conventions, in here you ordinarily send data in a single direction, starting from source to final place without verifying whether the destination is present at this moment also, or in the event that it is set up to get the information (Alan, H. F., & Kaur, J, 2016).

TCP is association situated. Setting up an association implies that toward the start of a TCP call, it completes a “three-way handshake” so the destination realizes that an association with the initial call has been set up. It monitors that address inside, so it expects more bundles from it, and have the option to send answers to every parcel it gets (Jorgensen, J. W., 2017).

Each layer makes a trick of the one adjacent to it. The TCP receives a HTTP message and split it into bundles. Let’s assume that as information bundles. The IP receives these bundles sequentially from TCP and tosses it to destination; additionally, it gathers an approaching parcel and conveys it to TCP.

3. Mention one advantage and one disadvantage of Agile method.

Solution 3

Advantages

1. Day by day adaption of changing the requirement and frequent delivery nonstop delivery of valuable programming or softwares.
2. Individuals and communications are underscored as opposed to process and devices. Clients, engineers and analysers always communicate with one another.

Disadvantages

1. The task can be done with less documentation with the help of experienced resources.

4. Compare and contrast the Agile method and Evolutionary software development process. Explain with an example.

Solution 4

Agile	Traditional
1. Group conducts experiments with different strategies and bit by bit touches base at the most ideal arrangement	1. Pursues a top down methodology, and doing changes isn’t simple as completing one stage prompts another
2. In agile method, there is free progression of correspondence, anybody can display their thoughts inside the group	2. It has working style of type leadership.
3. This is increasingly adaptable when contrasted with conventional model, as it can alter its work process dependent on any new solicitation for alterations	3. Pre-arranging is completed to proceed with the different stages
4. Client inclusion is vital for this type of model to demonstrate its mettle (Abrahamsson, P., Salo, O., Ronkainen, J., & Warsta, J., 2017).	4.Customer is included just in the underlying phases of prerequisites gathering

5. Analyse the uniqueness of Apple design process.

Solution 5

Apple’s development technique includes astounding new items and imaginative plans of business model. Virtuoso ergonomics make Apple items easy to utilize. Configuration isn’t exactly what it resembles and feels like. Design is the means by which it works,” said Steve Jobs.

Apple has more than once exhibited with its development the board what a triumph ease of use and configuration can produce.

Quality is more focused as compared to other and Apple design is more successful because design is done. You need to notice that Apple does not really invent new products frequently. They focuses mainly on reinventions or recreations, looking for the weak areas of an already existing design and rectify that, making it better.

6. Describe three reasons for a project failure.

Solution 6

1. Poor Preparation

You required a reasonable idea of what you will do, ahead of time – On the other hand as much as could be expected. Subsequently, on the off chance that you don’t have a reasonable concentration at the at the soonest phase of the procedure, you are making things harder on yourself. Have a gathering, In spite of whether it is extensive, with partners to talk about their desires on cost, time and item quality as well.

2. Deficient Documentation and Tracking

This is the duty of the undertaking manager and detailed documentation and tracking is needed for every project in case if the team fails to produce the detailed documentation the project fails.

(Jørgensen, M., & Yamashita, A.,2016).

3. Terrible Leadership

When we see leadership, pioneer technique and, we typically think, that the task administrator. The general population at every administration level have a capability to guarantee that the task is productive. The executives should not micromanage but rather offer help to guarantee that the PM can conclude the desires put upon them.

7. Your company owns several software and asked you to manage them within company budget constraints. What will be your goals?

Solution 7

Time and cash both are rare assets to all people and every association. A budget limit is an arrangement indicating the organization’s targets and how the executives expects to secure and make the most of assets to achieve those goals (Calderón, A., & Ruiz, M., 2015).

The below are the goals:

• Control spending
• Limit startling income issues
• Better educated choices in different divisions
• Helps with financing applications
• Educates monetary focuses for office pioneers
• Reduce risk
