Understanding Network Topologies

Network topology refers to the arrangement of elements in a communication network, such as computers, routers, and switches. It plays a crucial role in determining a network’s performance, scalability, and reliability.

Significance of Topologies

  1. Efficient Communication: A well-structured topology ensures smooth data transfer.
  2. Scalability: A good topology helps in expanding the network easily.
  3. Fault Tolerance: Some topologies are resilient to failures, ensuring uninterrupted

Data Abstraction and Its Three Levels in DBMS

Data abstraction is a logical function in a Database Management System (DBMS) that separates the raw data from the front end. It hides the complexities of how data is stored and managed, providing a simplified view of the data to users and applications. Since efficiency often requires complex data structures to represent data, developers hide this complexity from users through several levels of abstraction to simplify interactions with the system:
