NoSQL databases are broadly categorized into different types, with document-based and column-based models being among the most widely used. Document-based databases, such as MongoDB, store data in flexible, self-describing documents—typically in JSON or BSON format—allowing complex, nested structures and varying fields for different records within the same collection. This flexibility supports agile development and easy mapping to application objects, making it ideal for applications with evolving

1. RAM (Random Access Memory):
Definition: RAM is a type of volatile memory that stores data and instructions currently in use by the processor. It allows the CPU to access data in any order, hence the term Random Access.
Characteristics:
Volatile: Data is lost when power is turned off.
Fast: It provides quick data access and is essential for efficient processing.
Read/Write: Supports both reading and writing of data.
Types:
