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:
Declare total = 0
Explanation:
Given
Variable name: total
Variable type: integer
Variable value: 0
Required
Write a pseudocode statement
Because total is meant to hold integer values, it can be initialized as:
total = 0
Using total = 0.0 means that total is meant to hold floating values. So, we make use of
total = 0
However, this variable must be declared before being initialized.
So, we make use of the following statement to declare the variable:
Declare total
"Declare total" and "total = 0" gives:
Declare total = 0
The number of ways to deploy network connectivity in the 25 classrooms, 12 faculty offices and a common area is 5200300 ways
<h3>How to distribute network connectivity?</h3>
We should know that permutation relates to the act of arranging all the members of a set into some sequence or order
The given parameters are
25 classrooms
12 faculty offices and 1 common area
⇒ n
=
=
Simplifying the expression we have
5200300 ways
Therefore, the network connectivity can be done in 5200300 ways

Bios, This stores all of the computers start-up information. It tells the computer where to find the operation system inside the main storage and how to start it.
Hope this helps! :)
