Object oriented programming or OOP is a way of writing programs using objects where each object has its attributes and set of operations defined by its class. An object is a data structure in memory that has attributes and methods. The attributes of an object are the same as variables and the methods of an object are the same as functions or procedures.

Memory is divided into number of fixed size blocks called Frames. The virtual address space or logical memory of a process is also broken into blocks of the same size called pages. When a program is to be run, its pages are loaded into any frame from the disk. Mapping is done thru Page Map Table which contains the base address of each page in physical memory. Hardware support is given to paging using Page Map Table Register (PMRT) which will be pointing to beginning of the PMT. Look side memory or Content addressable memory is used to overcome the problem of PMT.
