Tim would like to send a confidential, encrypted message to Kellie using asymmetric cryptography. What key should Tim use to create the message?
Tim uses the public key is used to create the message
Asymmetric cryptographyAsymmetric (public key) encryption allows the sharing of an encrypted message without a shared secret key. Public key encryption uses two keys, one public and one private. To send a message, asymmetric algorithm with the public key is used to create the message while the private key is used for the message decryption. The encryption function can only encrypt data.

Elena wrote the following code in Scratch to have the sprite move and then turn around. However, the code does not work as expected. What should be done to fix the error?
Change "move 20 steps" to "move 10 steps"
Change "turn left 180 degrees" to "turn left 90 degrees"
Change "turn left 90 degrees" to "turn right 180 degrees"
Change "turn right 90 degrees" to "turn left 90 degrees"
Sprites are program objects used to create animations
What should be done to fix the error is to (d) Change "turn right 90 degrees" to "turn left 90 degrees"
How to fix the errorFrom the question, we have the following highlights
The sprite is to move forwardAnd then turns aroundThe first line of the code segment moves the sprite 20 steps forward;
This step is correct, and it does not need to be changed.
For the sprite to turn, then it must rotate 360 degrees in a direction.
From the code segment, we have the following rotations
180 degrees left90 degrees left90 degrees rightWhen the angles of rotation are added, we have:
[tex]\theta = 180 + 90 - 90[/tex]
[tex]\theta = 180[/tex]
i.e. the code segment implements a 180 degrees rotation
In order to turn the sprite around, she needs to change the 90 degrees right to 90 degrees left.
So, we have:
[tex]\theta = 180 + 90 + 90[/tex]
[tex]\theta = 360[/tex]
Hence, the fix to the error is (d) Change "turn right 90 degrees" to "turn left 90 degrees"

Byte pair encoding is a data encoding technique. The encoding algorithm looks for pairs of characters that appear in the string more than once and replaces each instance of that pair with a corresponding character that does not appear in the string. The algorithm saves a list containing the mapping of character pairs to their corresponding replacement characters.
For example, the string "THIS_IS_THE_BEST_WISH" can be encoded as "%#_#_%E_BEST_W#H" by replacing all instances of "TH" with "%" and replacing all instances of "IS" with "#".
For which of the following strings is it NOT possible to use byte pair encoding to shorten the string’s length?
a) "BANANA"
b) "LEVEL_UP"
c) "MEET_ME_LATER"
d) "NEITHER_HERE_NOR_THERE"
Answer:
The encoding algorithm looks for pairs of characters that appear in the string more than once and replaces each instance of that pair with a corresponding character that does not appear in the string. ... Byte pair encoding is an example of a lossy transformation because it discards some of the data in the original string.

/* String Declaration*/
char nickname[20];
printf("Enter your Nick name:");
/* I am reading the input string and storing it in nickname
* Array name alone works as a base address of array so

Explanation:
An IPv4 address has 32 bits, so there are 232 (over 4 billion) possible IPv4 addresses. Since the Internet is gaining devices quickly, we will soon surpass 232 unique devices on the Internet.
In anticipation of all the new Internet devices, we are in the process of switching to IPv6, which uses 128 bits for a single address. That’s 96 extra bits to represent one address!
Which of the following statements correctly describes how many more addresses will be possible to represent by switching from IPv4 to IPv6?
i. 96 more addresses can be represented with IPv6
ii. 296 more addresses can be represented with IPv6
iii. 96 times as many addresses can be represented with IPv6
iv. 296 times as many addresses can be represented with IPv6
Answer:
Explanation:IPv4 is almost used up due to the constant increase in devices so therefore IPv6 was implemented to combat this issue, IPv6 uses 128 bit addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total. Which essentially means both me and you wont see IPv6 run out in our life times nor will you kids kids.
The 96 times as many addresses can be represented with IPv6. Hence option 3 is correct.
What are addresses?Addresses are defined as the address, street name, and town name where a person resides or works and where mail can be sent: her home and office addresses. a shift in address. Memory addresses are used by computer programs to execute machine code and store and retrieve data. A device or CPU uses a memory address as a specific identifier to track data. The CPU can keep track of where each memory byte resides in the system by using this binary address, which is determined by an ordered and finite sequence.
The magnitude of IP addresses is the fundamental distinction between IPv4 and IPv6. Unlike IPv6, which has a 128-bit hexadecimal address, IPv4 has a 32-bit address. Compared to IPv4, IPv6 has a broad address space and a straightforward header.
Thus, the 96 times as many addresses can be represented with IPv6. Hence option 3 is correct.

Why don't we use a for each loop when doing a sequential (linear) search?
Answer:Linear search (aka Sequential Search) is the most fundamental and important of all algorithms. It is simple to understand and implement, yet there are more subtleties to it than most programmers realize.
The input to linear search is a sequence (e.g. an array, a collection, a string, an iterator, etc.) plus a target item. The output is true if the target item is in the sequence, and false otherwise. If the sequence has n items, then, in the worst case, all n items in the sequence must be checked against the target for equality. Under reasonable assumptions, linear search does O(n) comparisons on average. In practice, this is often too slow, and so, for example, BinarySearching or hashing or TreeSearching are speedier alternatives.
Here's an implementation of linear search on an array (in Java):
