Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

The collection of n tasks with known processing times and due dates can be referred to as the EDD rule; the least value of Lmax is obtained by sequencing the jobs in non-decreasing order of their due dates.
The goal of the interval scheduling maximization problem (ISMP) is to identify the largest compatible set, or a collection of intervals with the least possible overlap. The idea is to optimize throughput by completing as many tasks as you can.

Assume Host A wants to send an IP datagram to Host B, but neither A's nor B's ARP caches contain B's MAC address. Assume that the forwarding table of switch S1 only contains entries for Host B and router R1.
Explanation in Detail:
Because the destination address of the received ARPframe is a broadcast address, Switch S1 will broadcast the Ethernet frame over both of its interfaces. And it discovers that A lives on Subnet 1, which is linked to S1 via the interface connecting to Subnet 1. S1 will also add an entry for Host A to its forwarding table.
Yes, router R1 receives this ARP request message, but R1 does not forward it to Subnet 3. B will not send an ARP query message requesting A's MAC address because A's query message contains this information. When switch S1 receives B's response message, it will create an entry in its forwarding table for host B and then drop the received frame because destination host A is on the same interface as host B. ((In other words, A and B is in the same LAN segment).
