Answer 3

Depends on what you are talking about. If it is just basic stuff it could be Disk storage, tape storage and the various classes like that. If you are talking about Corporation and SAN it could be storage tiers like 15K high speed fibre channel disks, 10K FC disks, SATA drives and then tape archiving classes related to the data life cycle. and so on. I think you need to be more specific in the question.

Answer 4

Storage class refers to the permanence of a variable, and its scope within the program, i.e., the portion of the program over which the variable is recognized. There are four different storage class specification in languages c and c++:
They are:
1)Automatic
2)Global or Extern
3)Static
4)Register

1)Automatic-An automatic variables does not retain its value once control is transferred out of its defining function

2)Extern or Global-Glogal variables are not confined to single function. global variable are recognized globally, they can beaccessed from any function that falls within their scope. they retain their values within that scope. Alteration to the value of an global variable within a function will ba recognized within entire scope of the external variable.

3)Static- Static variables are defined within a function in the same manner as automatic variables, expect that the variable declaration must begin with static storage-class designation. Static variables can be utilized within the function in the same manner as other variables. They cannot, however be accessed outside their defining function.

It is not unususal to define automatic or static variables having the same names as global variables. In such situation the local variables will take the precedence over the global variables, through the values of the global variables will be affected by any manipulation of the local variables. Thus the global variables maintain their independence from locally defined automatic and static variables. The same is true of local variables within the one function that have the same names as local variables within another function

4)Register-The register and automatic storage class are closely related. In particular the ir visibility(i.e., their scope) is the same. Thus the register variables,like automatic variables, are local to the function in which they are declared. Furthermore the rules governing the use of register variables are same as those for automatic variables, expect that the address operator(&) cannot be applied to register variables.

Hope this helps a little!!!
