"A variable is an abstract storage location paired with an associated symbolic name, which contains some known or unknown quantity of data or object referred to as a value."

"In simpler terms, a variable is a named container for a particular set of bits or type of data."
"A variable can eventually be associated with or identified by a memory address."
"The variable name is the usual way to reference the stored value."
"This separation of name and content allows the name to be used independently of the exact information it represents."
"Yes, the value of the variable may thus change during the course of program execution."
"Variables in programming may not directly correspond to the concept of variables in mathematics."
"Variables in computer programming are frequently given long names to make them relatively descriptive of their use."
"Variables' storage location may be referenced by several different identifiers, a situation known as aliasing."
"Assigning a value to the variable using one of the identifiers will change the value that can be accessed through the other identifiers."
"Compilers have to replace variables' symbolic names with the actual locations of the data."
"A variable's name, type, and location often remain fixed."
"Yes, the data stored in the location may be changed during program execution."
"The identifier in computer source code can be bound to a value during runtime."
"Variables can hold different types of data such as integer, float, string, etc."
"The variable name is the usual way to reference the stored value."
"A variable contains some known or unknown quantity of data or object referred to as a value."
"Variables in mathematics often have terse, one- or two-character names for brevity in transcription and manipulation."
"The separation of name and content in a variable allows the name to be used independently of the exact information it represents."
"No, a variable can contain different types of data, not necessarily part of an equation or formula like in mathematics."
