Answer:
columns, rows
Explanation:
In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.
Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.
These data can be stored or organized in a database management system through the use of multiple-column record formats.
In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.
Answer:
To create a public key signature, you would use the <u>_private_</u> key.
Explanation:
To create a public key signature, a private key is essential to enable authorization.
A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.
The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.
The public key uses different keys to make data readable and unreadable.
The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.
Answer:
True.
Explanation:
For all the count values, if Ranfun() returns true then all the values of count would be printed. Then the sequence of count values printed would be 1 2 3 4 5. Also for all the values of count if Ranfun() returns false then all the values would be enqueued. When we try to dequeue elements from queue we would get them in the same order of their entry into the queue. Thus, the sequence would be 1 2 3 4 5. Hence, we can say that this output sequence is possible. TRUE.
