What is constant explain their storage representation with suitable example?
A constant is a variable that is immutable. The storage representation is exactly the same as for any other variable of the same type, the only difference is that all constants are allocated in the program's data segment (static memory).
What are the 'Constants' and 'Variables' in Java?
A variable is a memory address that holds a value. A constant is simply a variable that does not change value.
In IT What is the difference between a user variable and a system variable?
A user variable is a memory which is used in specific function or functionality. A system variable is kinda of generic, accessible to all users of the system. It does not bind to specific process as such.
Difference between reference variable and instance variable?
An object is the actual storage space in memory in which some collection of data resides.A reference variable is a variable which refers to the memory location of an object.Look at the pseudocode below:Object obj = new Object();Here obj is the reference variable, and the data to which it refers is the object.
Difference between int a and extern int a. why the first one is definition while the second is declaration please explain?
The declaration 'int a' both declares the variable of 'a' and allocates memory for it. When you use 'extern' you are referring to a variable called 'a' that has its memory allocated in another module. The actual variable 'a' is not in the same compilation unit as the current one being compiled. Where the variable 'a' is located is resolved by the linker. When using 'extern' you state your intent to use a variable called 'a', but it doesn't reserve any memory for it in the current module.
What is a variable plus a variable?
A variable is a named memory location for which the contents are volatile. The antonym of variable is constant.
Where is constant variable stored?
Random Access Memory (RAM)

Difference between multistore and working model memory?
what is the difference between the memory store model and the working memory model?
What is the difference between segmentation and compaction?
Segmentation involves dividing memory into variable-sized partitions to allocate memory dynamically, while compaction rearranges memory to reduce fragmentation by moving allocated memory blocks closer together. Segmentation deals with memory allocation, while compaction improves memory utilization.

What is the difference between object and variable?
A variable basically holds a single type literal in memory through defining its type, declaring it, and setting a value to it. If you meant reference variables, they are variables which refer to the memory location of an object previously set.An object is the actual storage space in memory in which some collection of data resides (is stored). Objects 'live' in memory spaces known as 'heaps'.
What is the difference between a memory stick and a memory stick pro?
