A useful advantage of Asymmetric encryption over symmetric
encryption is that there is no secret channel necessary for the
exchange of the public key, unlike in the symmetric encryption which requires a
secret channel to send the secret key.
Another
advantage of Asymmetric encryption is that is has increased security. Asymmetric
uses two different keys (Public and private) for both encryption and decryption
of data while symmetric uses one.
Explanation:
Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.
- A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
- A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.
<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>

Answer: 33
7 times 4 is 28 add the left over 5 makes 33 people
Answer:
The formula and value to this question is "=A1+A3+A4+A5 with value 100"
Explanation:
The explanation of the given question as follows:
- In question, it is defined that four cells that are "A1, A2, A3, and A4" contains value that are "10, 20, 30, and 40".
- To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
- If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".
Answer: 1820
Explanation:
I <u>believe</u> the answer is the 1820, as the introduction of steam powered printing presses and steam powered paper mills significantly lowered the cost of books to decrease and significantly increased their circulation/availability.
hope this helps
