Understanding Network Topologies, Protocols, and QoS
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
- Efficient Communication: A well-structured topology ensures smooth data transfer.
- Scalability: A good topology helps in expanding the network easily.
- Fault Tolerance: Some topologies are resilient to failures, ensuring uninterrupted
Core Concepts in Database Management Systems (DBMS)
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:

Mastermind Game Logic Implementation in Python
This section provides Python functions for implementing the core logic of the Mastermind game, including calculating clues and finding compatible combinations. Note that muertos refers to Black Pegs (exact matches) and heridos refers to White Pegs (correct color, wrong position).
1. Counting Color Occurrences
def occurrences(color: str, comb: str) -> int:
""Counts how many times a specific color appears in a combination""

Routing in Packet Switching Networks
Routing is a key design issue for packet-switched networks, involving selecting the optimal route across the network between end nodes.
Required Routing Characteristics
- Correctness
- Simplicity
- Robustness
- Stability
- Fairness
- Optimality
- Efficiency
Internet Routing Protocols
Routers are responsible for receiving and forwarding packets through interconnected networks. They make routing decisions based on knowledge of the topology and traffic/delay conditions, exchanging information
