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.

Answer:
1946
First, to deal with the more recent and most familiar meaning of the word ‘computer’: the word first came to mean an electronic device used to store and communicate information (and all of its subsequent functions) only in the 1940s: the earliest citation in the Oxford English Dictionary is from 1946. This is fitting.
Explanation:
I would say the primary Beni fit is more space for storage , but also it does effect the speed eventually. If your hard drive is almost full, everything will be slower
Answer:
6
Explanation:
The tree is the hierarchical structure in the data structure, it has the properties like nodes, height, level etc.
the formula for calculating the maximum number of node at the given level.
here, l is the level of node.
in the question the number of node is 46.
Substitute in the formula:
The Approx. value of level is 6
