Buffers are time reserves added to each stage of the critical chain, and they ensure that the project remains on schedule. Buffers are incorporated into a project schedule to secure the timely delivery of project stages.
The buffers are added to the network where non-critical paths merge with the critical chain to protect the critical chain from being delayed. This is a true statement. The critical chain is the longest path of the project network, and it determines the completion date of the project. In contrast, non-critical paths are those that are not vital for the project completion. It gives additional time to complete the critical chain by using time reserved on other chains. Buffers safeguard against inevitable issues such as workmanship and supply chain. Buffers are found in two places, feeding and project completion buffers. Feeding buffers are employed to protect critical chain stages from disruptions that are likely to occur as a result of variation in previous tasks. Feed buffers are used in tasks that are fed by a single task. Project completion buffers, on the other hand, are used to protect the whole critical chain from unforeseen delays in any of its stages. The answer is, "true".

what are the advantages and disadvantages of prototyping? describe the steps in prototyping. give at least two circumstances under which prototyping might be useful.
Prototyping is a useful tool to help spot potential flaws and identify areas for improvement, reducing the likelihood of design errors. Prototyping helps in a more detailed and better analysis of data, facilitating better decision-making. Prototyping is used as an effective communication tool between the team and clients.
Advantages of Prototyping: Here are the advantages of prototyping: Prototyping enables a preview of the product or process. It allows businesses to have an idea of how their product or service will look before they invest in it completely.
Disadvantages of Prototyping: Here are the disadvantages of prototyping: The process of prototyping can be expensive in both time and money. It can also delay the final product from being completed. Poor communication between the development team and the client can cause errors to go unnoticed, rendering the prototype irrelevant. There is a chance that prototyping may not be useful when building larger systems. This is due to the complexity of the system and the number of components involved.
Testing: Once the prototype has been built, it is tested by the team and/or the users to identify any flaws or bugs. Feedback is then provided for improvement. Improving: Based on the feedback, the team can identify areas for improvement and work on them until they come up with the final product.
Circumstances under which prototyping might be useful: Prototyping is useful under these circumstances: Prototyping is useful when creating a new product or process. It allows the team to get a clear idea of what they are building and how it will look. Prototyping is useful when designing user interfaces. It enables designers to create a working interface, allowing users to provide feedback and identify areas for improvement.
The advantages of prototyping include the ability to identify design flaws early, gather user feedback, and improve communication among team members. Disadvantages of prototyping include the potential for wasted resources, insufficient analysis, and misleading results.
The steps in prototyping are:
1. Define objectives: Determine the purpose and goals of the prototype.
2. Create a design: Sketch or model the prototype based on the objectives.
3. Build the prototype: Construct the prototype using appropriate materials and tools.
4. Evaluate and refine: Test the prototype, gather feedback, and make improvements as necessary.
5. Finalize the design: Complete the design based on the evaluation results and prepare for implementation.
Two circumstances under which prototyping might be useful are:
1. When developing a new product or system, it helps identify potential issues and gather user feedback before committing to full-scale production.
2. When making changes to an existing product or system, it allows testing of new features or modifications without disrupting the current implementation.

which type of password attack is used on weak passwords and compares a hashed value of the passwords to the system password file to find a match?
The type of password attack that is used on weak passwords and compares a hashed value of the passwords to the system password file to find a match is known as a dictionary attack.
A dictionary attack is a type of password attack in which an attacker uses a precompiled list of words, often drawn from a dictionary, and compares each word's hashed value to the password hash in the system password file to find a match. This type of attack is effective on weak passwords that can be easily guessed by an attacker.
It is important to use strong passwords that are difficult to guess in order to prevent successful dictionary attacks. Additionally, system administrators can implement measures such as salting and hashing to make it more difficult for attackers to obtain a user's password.

consider a packet of 4000 bytes (including 20 bytes ip header and 3980 data bytes) that must pass a link with maximum transfer unit (mtu) being 1500 bytes. let x be the 16-bit identifier of the packet. how many fragments will this packet be divided into? give the values of the following fields in the ip header of each fragment packet: length, identifier, fragflag, and offset. (hint: check the pages of ip fragmentation in chap4-5.pptx)
This process of fragmentation allows packets to be Transmitted across a network despite the limitations of the maximum transfer unit.
When a packet of 4000 bytes with an IP header of 20 bytes and 3980 bytes of data is transmitted through a link with a maximum transfer unit (MTU) of 1500 bytes, it will need to be fragmented into multiple packets. The maximum size of each fragment will be 1480 bytes (1500 - 20 bytes of IP header).
To determine the number of fragments, we first need to calculate the total number of bytes that need to be transmitted (including the IP header). This would be 4020 bytes (4000 + 20 bytes of IP header). Next, we divide this number by the MTU size of 1500 bytes to get the number of fragments required. This comes out to be 3 fragments.
The first fragment will have the length field set to 1500, the identifier field will be set to x, the flag field will be set to 1 (indicating that this is the first fragment), and the offset field will be set to 0.
The second fragment will have the length field set to 1500, the identifier field will be set to x, the flag field will be set to 1 (indicating that this is the second fragment), and the offset field will be set to 1480 (since the first fragment has already taken up the first 1480 bytes of the original packet).
The third fragment will have the length field set to 1040, the identifier field will be set to x, the flag field will be set to 0 (indicating that this is the last fragment), and the offset field will be set to 2960 (since the first two fragments have already taken up the first 2960 bytes of the original packet).
Overall, this process of fragmentation allows packets to be transmitted across a network despite the limitations of the maximum transfer unit. Each fragment is still able to carry all the necessary information and can be reassembled at the destination to form the original packet.

your company wants to purchase some network hardware to connect its separate networks together. what kind of network device is appropriate?
To connect separate networks together in your company, an appropriate network device would be a router. A router is designed to forward data packets between different networks, providing a connection between them.
Step-by-step explanation:
1. Identify the networks you want to connect.
2. Determine the number of ports needed on the router, based on the number of networks you wish to connect.
3. Purchase a suitable router with the required number of ports.
4. Configure the router with the necessary settings, such as IP addresses and routing protocols, to enable communication between the separate networks.
5. Connect the router to the different networks using appropriate cables.
6. Test the connection and make any necessary adjustments to ensure smooth communication between the networks.

Explanation:
Of course this code lacks error handling, but it shows an approach using the scanner object and array lists.
a data analyst reviews a database of wisconsin car sales to find the last five car models sold in milwaukee in 2019. how can they sort and filter the data to return the last five cars sold at the top of their list? select all that apply.
A data analyst can sort and filter the data to return the last five cars at the top by taking Filter out sales outside of Milwaukee, Filter out sales not in 2019 and Sort by date in descending order. So, options A, B and D are correct.
To return the last five car models sold in Milwaukee in 2019, the data analyst can use the following sorting and filtering techniques:
Filter out sales outside of Milwaukee: This can be done by applying a filter on the location column of the database, selecting only the rows where the location is Milwaukee.Filter out sales not in 2019: This can be done by applying a filter on the date column of the database, selecting only the rows where the year is 2019.Sort by date in descending order: This can be done by sorting the filtered data by date column in descending order, so that the most recent sales are at the top. This can be achieved using the "ORDER BY" clause in SQL or similar sorting functions in other data analysis tools.Here's a step-by-step approach for achieving this in SQL:
-- Step 1: Filter out sales outside of Milwaukee
SELECT *
FROM car_sales
WHERE location = 'Milwaukee';
-- Step 2: Filter out sales not in 2019
SELECT *
FROM car_sales
WHERE location = 'Milwaukee' AND YEAR(date) = 2019;
-- Step 3: Sort by date in descending order and limit to last five rows
SELECT *
FROM car_sales
WHERE location = 'Milwaukee' AND YEAR(date) = 2019
ORDER BY date DESC
LIMIT 5;
