We often call "undefined terms" variables. Their value is not known; it can vary. And thus the name we assign them is variable.
In mathematics, a variable is a representation, in the form of a letter, of a numerical value. Variables are traditionally used when the value it represents is either unknown or can vary.
A parameter can be thought of as a constant variable. It is a variable for which you determine a value, or whose value you change to see its effects on the situation modeled. The term is used in Geometry, Statistics, Physics and Engineering nas well as other fields.
Dependable variable is a term used in mathematics. Essentially, it is an element that changes it's value depending on the values of other elements.
A variable is used to hold value. The value may vary in every usage. An empty box is used to hold things. So, it can have in it the things we put in. The things to be held in the empty box,can change upon every usage. So, an empty box is like a variable.

I will give examples in the Java language.Assign a value to a variable, with the equal sign. For example, if you want the variable "a" to have the value 5:int a;a = 5;Note that the first sentence declares the variable, this has to be done only once. After that, you can assign values to the variable several times; each value you assign will erase the previous value.The declaration and the assignment can be combined, thus:int a = 5;

This answer applies to programming languages in general. The equals sign is used for assignment. For example, the code "$variable = 1" assigns the value of 1 to the variable $variable. If you want to test whether values are the same (equality) the double equals sign is used. For example, when you want to verify that $variable has been assigned the value of 1 you would use: $variable == 1
In programming, select case statement is a way to test the inside of a variable. It is used when one knows there is a limited number of things that can be in the variable.
operator to compare two objects. The simple "=" sign is used for assignment - assigning a value to a variable. Here are examples of the two: x = 15; // Assign the value 15 to the variable if (x == 10) ... // Compare variable "x" with some value
== (the double equal sign) is used to compare two values (resulting in true if they are equal, false otherwise). = (a single equal sign) is used to assign a value to a variable.
The SQL statement used to update data in a database is the "UPDATE" statement. It allows you to modify existing records in a table by specifying the column and value you want to update based on certain conditions. Additionally, you can use the "SET" keyword to assign new values to specific columns in the table.
A variable is just a memory location of a valuea variable is accessed by a namesuppose of the integer type u got a variable aSoDECLARATION-int a;and then store any integer value to a.a=4;or take input from user.then perform any arithmetic function on a.a+5;returns 9;there are different variables but the essential concept behind variables is the same!
