Facts:What is virtual memory?Virtual memory is a memory management technique where secondary memory can be used as if it were a part of the main memory. Virtual memory is a common technique used in a computer'soperating system (OS).Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM 2) todisk storage. Mapping chunks of memory to disk files enables a computer to treat secondary memory as though it were the main memory.Question(s):1. When will there be a drawback in using a Virtual Memory and why?

Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Question

Facts:
What is virtual memory?
Virtual memory is a memory management technique where secondary memory can be used as if it were a part of the main memory. Virtual memory is a common technique used in a computer's
operating system (OS).
Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM 2) to
disk storage. Mapping chunks of memory to disk files enables a computer to treat secondary memory as though it were the main memory.
