Answer:
The reason is that the windowing system consumes significantly more memory and virtual memory than the text mode.
Explanation:
The reason behind the occurrence of this is that the windowing system consumes significantly more memory and virtual memory than the text mode. As a result, this reduces the likelihood of the hard disk becoming inactive for long enough for it to be powered down by itself with no direct human control, i.e. automatically.
Answer:
Option A i.e., a pass statement are the correct option.
Explanation:
The following option are correct because a pass statement is used when you want to create any function or any loop or statement but you don't want to write code inside the function or any loop or statement then, you use the "pass" keyword inside that function or any loop or statement as null or nothing happen when the following code is execute.
Answer:
Encryption method security:-
- Encryption method representing each alphabetic character as an integer between 0 and 25.
- Now, apply RSA algorithm for each integer is not an efficient secure encryption method.
Explanation:
- Let consider alphabetic characters set {A, B... Z} .
- Each alphabetic character forms a set of message block values M={0,1,2...,25).
- From encryption method the corresponding cipher text block value C = {0e mod n,1e mod n, 2e mod n,..., 25e mod n}.
- Then, compute the cipher text with knowledge of Bob's public key;
- If the public key is generated, then possibility to decrypt the cipher text to plain text.
- The generated public key is easily calculated by everyone and security is lost.
- Therefore, the encryption method is not secure.
Encryption method is not secure, Most efficient attack against this method:-
- Now, compute the encryption message with the function Me mod n for all the possible values of M.
- This is the most efficient attack against the scheme in encryption method.
- Then, create a look-up table with cipher text as an index to the corresponding plain text as a value for appropriate location in the table.
Answer:
b. Thin provisioning
Explanation:
Thin provisioning is a storage space feature that makes allocating disk storage space flexible based on the space needed by each user, it improves the way storage space is utilized.
