The combination of channels that a computer technician wants to purchase a cable modem capable of combining multiple channels to increase traffic flow from two 20 MHz channels to a single 40 MHz channel is called channel bonding.

Channel bonding refers to combining two or more independent channels to create a larger data pipe for increased data rates. When cable modems use this method, it's known as "channel bonding." Channel bonding is used to increase the efficiency of data transfer, particularly in high-bandwidth applications, by combining several channels into a single link.The following are the advantages of channel bonding:Increased bandwidth: Since two or more channels are combined into a single data path, channel bonding effectively doubles or triples the bandwidth rate. As a result, you may receive data more quickly and smoothly on your device.Smoother data transfer: Channel bonding also improves the data transfer experience because data flows more smoothly through the merged channels.Improved reliability: Channel bonding enhances signal quality and consistency, which can help to prevent buffering, lagging, and dropped connections during use.

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.

The commands that can be used to save and undo table changes are "commit and rollback".Answer: c. commit and rollback

To perform transactions in the database, the SQL provides the following four important commands:commit: If a transaction is successful, the commit command is used to save the changes. rollback: In the case of an error or as per the user’s need, the rollback command is used to undo the changes made in the table. The entire transaction is rolled back when the rollback command is executed. save: It stores the data or transaction from the session in the database memory temporarily. The save command does not store it permanently. The save command saves the specified data points at the moment, but not in the memory. commit and rollback are the two primary commands that are used to save and undo table changes.

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.

Explanation:

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.
