Answer: d)The cross sections of the slices are disks.
Explanation:The slicing method deals with the elimination of the horizontal layer of the solid body .It is considered that disk method is the special case of the slicing method.
Disk method consist of the slices that are used for the estimated volume of the solid body of revolution that are known as disk.The solid body revolving around a line and its volume is estimated.Thus, the correct option is option (d).
A potential cause of this issue with FTP is that the server is not able to resolve the client IP address.
FTP is an acronym for file transfer protocol and it can be defined as a type of server that is designed and developed to store and provide files for download and sharing between two or more users on a computer system.
In this scenario, the user is most likely experiencing issues when trying to transfer files through the file transfer protocol (FTP) because the server is not able to resolve the client IP address, which is the address of the recipient of the file.

Based on the given description in the question, the maximum cardinality assignment of the customer and vehicle is; one customer to one vehicle mapping
Cardinality is simply defined as the mapping of entities or group of entities to a certain cardinal value. This means that cardinality seeks to highlight the relationship between two objects such as eggs in a crate or shoes on a rack.
Now, in this question, we see that the car dealer sells one car to a customer and tracks the customer and manufacturer for that particular vehicle. This is simply 1 to 1 mapping and as such the maximum cardinality assignment of the customer and vehicle is one (1) to one (1) mapping.

Answer:
Customer(1) - (1) Vehicle.
Explanation:
Cardinality is the mapping of entities or group of entities to a cardinal value. It tries to show the relationship between two objects like a cups in a shelf or plates in racks.
The car dealer in the question, sells one car to a customer and keep or prioritise the record of the main owner of the acquired vehicle. So the maximum cardinality assignment of the customer and vehicle is one (1) to one (1) mapping.

Explanation:
Half-duplex serial data transmission allows for communication in both directions, but only one direction at a time. In applications such as walkie-talkies and traditional telephone systems.
In half-duplex serial data transmission, data is transmitted in one direction at a time
1. Sender initiates transmission: The sender, also known as the transmitter, starts the data transmission process. It prepares the data to be sent and waits for the appropriate time to start transmitting.
2. Sender sends data: The sender begins sending the data in a sequential manner. It breaks down the data into smaller units called frames or packets.
3. Receiver acknowledges receipt: After receiving each frame, the receiver acknowledges its successful reception to the sender.
4. Sender waits for acknowledgment: Upon sending a frame, the sender waits for the receiver's acknowledgment. If an acknowledgment is received, the sender proceeds to send the next frame.
5. Receiver processes the data: The receiver receives the frames and processes the data within each frame. It checks for errors using techniques like checksums or cyclic redundancy checks (CRC).
6. Roles switch for bidirectional communication: Once the sender finishes transmitting its data, the roles switch and the receiver becomes the sender, initiating its own transmission.
7. Communication continues: The process continues as the receiver sends its data and waits for acknowledgments, while the new sender processes the received data and sends acknowledgments.
Overall, half-duplex serial data transmission allows for communication in both directions, but only one direction at a time. This type of transmission is commonly used in applications such as walkie-talkies and traditional telephone systems.

Answer:
In half duplex mode, the signal is sent in both directions, but one at a time. In full duplex mode, the signal is sent in both directions at the same time. In simplex mode, only one device can transmit the signal. In half duplex mode, both devices can transmit the signal, but one at a time.
