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.
<u>Explanation:</u>
Note, the Wireshark software application is unique in that it has the ability to perform multiple layers of individual packet analysis.
Whereas in NetWitness Investigator software application, even though it doesn't go deeper like Wireshark, it can still detect new threats or problems in a network and then organized all of such information for the administrator.
So, in a sense, by using both applications, a network administrator can find the problems (using Wireshark), while another application (NetWitness Investigator) organizes them for him.
number of possible pins = 9 x 10 x 10 x 4 = 3600
Answer:
True. A virus that loads itself onto the target system's memory, infects other files, and then unloads itself is called a: Direct-action virus.
