Classless inter-domain routing is known as CIDR. It is an approach to IP address distribution and packet routing. An IP address's network prefix is specified via CIDR.

CIDR (Classless Inter-Domain Routing) is a more effective and adaptable method of allocating and routing Internet Protocol (IP) packets than the conventional IP address classes. A variable-length subnet mask (VLSM) is used by CIDR to distribute IP addresses, enabling more accurate distribution and greater address space use. Routing is made easier and subnets may be easily created thanks to the CIDR notation, which specifies the amount of bits in the network portion of the address. Internet Service Providers (ISPs) and network administrators manage IP addresses and routing tables using CIDR, which has evolved into the industry standard for IP address allocation and routing.

Answer:

Sequence numbers is the right answer.

The Transmission Control Protocol (TCP) uses sequence numbers to put back together and change the order of the segments it has received. When a sender sends data over a TCP connection, it breaks the data up into smaller pieces and gives each piece a sequence number. Then, the receiver uses these sequence numbers to put the segments back in the right order and put the data back together.

TCP uses port numbers (choice a) to figure out which application is sending or receiving the data. But they are not used to put the segments back together or in a different order.

TCP uses acknowledgement numbers (choice c) to make sure that data has been successfully sent and received. They are not used to put the segments back together or change their order.

In IP (Internet Protocol), fragment numbers (choice d) are used to break up large packets into smaller pieces that can be sent over a network. TCP, on the other hand, works at a higher level of the networking stack and doesn't care about fragment numbers.

TCP uses sequence numbers to reassemble and reorder received segments. Port numbers, acknowledgment numbers, and fragment numbers are used in TCP, but not specifically for the reassembly and ordering of segments.

The Transmission Control Protocol (TCP) uses sequence numbers to reassemble and reorder received segments. When a TCP segment is transmitted, it is numbered with a sequence number, which the receiving system uses to reassemble the data stream in the correct order. Even if the segments arrive out of order, the TCP stack on the receiving end can use these sequence numbers to put them back together correctly.

Port, acknowledgment, and fragment numbers are used in TCP, but not specifically for the reassembly and ordering of segments. Port numbers are utilized for multiplexing and demultiplexing data between the sender and receiver. Acknowledgment numbers are used to confirm the receipt of data, and fragment numbers are not a concept of TCP at all, but rather, they are used in the IP (Internet Protocol) layer when segments are too large and need to be fragmented for transport.

The technique used to represent audio in digital form is known as digital audio. When an analogue audio signal is transformed into electrical signals—"on/off" pulses—rather than electromechanical signals, the digital audio chain is initiated. The signal is then further encoded to guard against any faults that might happen during signal transmission or storage. The "channel coding" is necessary for the digital system to reconstruct the analogue signal when it is replayed. Eight to Fourteen Bit Modulation, a channel code used in audio Compact Discs, is an illustration.With a specific sampling rate and bit resolution, an analogue signal is transformed into a digital signal that may have many channels (2 channels for stereo or more for surround sound).

In continuous data protection (CDP) technology, the factor that determines how far back the recovery points can go is the retention period.

Retention period refers to the amount of time that a CDP system retains the historical data changes that have been captured. The retention period determines how far back in time a system can go to recover data. For example, if the retention period is set to 7 days, the CDP system can provide recovery points up to 7 days back in time.

The retention period is typically configured by the system administrator or the organization's IT policies. The retention period may vary depending on the organization's needs, compliance requirements, and the resources available to support the storage and management of the historical data changes.

It's worth noting that the retention period can also affect the performance and storage requirements of a CDP system. A longer retention period may require more storage space and may impact system performance, while a shorter retention period may limit the availability of recovery points.
