Document Summary
When using variables, we need to take into account the memory that they are associated with. So basically, variables take up spaces in the computer s memory. They are essentially convenient names like number and alpha in the code but every time a variable is used, it takes up some space. This space is not permanently reserved for the variable, as that would mess things up. So a computer allocates memory to a variable. That is the variable is given an area to store its value. A allocated variable does not need to have a particular value in it. It just needs to have an area to store value, a place to call home, no need for furniture. When the need for a variable ceases, then it is deallocated, the system reclaims the memory from the variable and it no longer has a place to call home.
