Answer:
B. Symmetric key encryption
Explanation:
Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.
Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) - a protocol for transmitting data privately on the internet.
Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.
The best option is therefore <em>symmetric key encryption</em>.

Answer:
The following where many reasons why IPv6 was used instead of IPv5 which are the limitation of it's 32 bit address, IPv5 began or used with a different name called Internet streaming, IPv6 provides unlimited addressing, because it comprises of 128 bit.
Explanation:
Solution:
The following reasons why Proponents of IPs used IPV6 instead of IPv5 is stated as follows:
- Due to its limited 32 bit addressing
- IPv6 offers almost unlimited addressing because of its 128-bit addressing
- IPv5 started under a different name which is internet stream(ST)
- ST(Internet streaming) was developed for streaming video and voice
- ST was developed by Apple, NeXT, and Sun Microsystems
- ST was effective on specific frequency to carry out communication
Answer:
The pseudocode is as follows
1. Input Steps
2. Input Day
3. Miles = Steps/2000
4. Calories = 65 * Miles
5. Print Calories
6. Stop
Explanation:
This line gets the number of steps for the day
1. Input Steps
This line gets the current day
2. Input Day
The line calculates number of miles
3. Miles = Steps/2000
This line calculates the calories lost
4. Calories = 65 * Miles
This line prints the calories lost
5. Print Calories
The pseudocode ends here
6. Stop
Answer:
.isLeapYear (1900) will return an incorrect response
Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.
<em>Hence, (a) answers the question;</em>
