Study Notes

Concurrent Processing in Distributed Systems

Concurrent processing aims to achieve simultaneous execution of multiple tasks to improve system performance and efficiency.

Defining Characteristics of Distributed Systems

Distributed systems are characterized by multiple autonomous computers that work together to achieve a common goal.

Scalability in Distributed Systems

Scalability refers to the ability of a system to increase its capacity and performance as the demand increases, without a decrease in performance.

Fault Tolerance in Distributed Systems

Distributed systems are designed to continue operating even after a fault has occurred, ensuring system reliability and availability.

Importance of Distributed Software Engineering

Distributed software engineering is important for enterprise computing systems as it enables the development of complex systems that can scale and adapt to changing business needs.

Heterogeneity in Distributed Systems

Heterogeneity involves the use of equipment and software from different vendors, which can lead to integration and compatibility challenges.

Design Issues in Distributed Systems

One of the design issues in distributed systems is the need to balance system performance, scalability, and fault tolerance.

Openness in Distributed Systems

Openness implies the ability of a system to be modified, extended, or integrated with other systems without restrictions.
Openness enables the use of equipment and software from different vendors.
Openness allows for flexibility and adaptability in system design.

Transparency in Distributed Systems

Transparency aims to achieve a system where the complexities of the system are hidden from the users, making it easier to use and maintain.
A fundamental aspect of transparency is that the system should be easy to understand and use.

Scalability Challenges

The main challenge addressed by scalability is to ensure that the system can handle increased load and demand without a decrease in performance.

Top-Down Control in Distributed Systems

Top-down control is impossible in distributed systems because of the autonomy of individual components and the lack of centralized control.

Failure Management Challenges

One of the challenges related to failure management is the difficulty of detecting and diagnosing faults in a distributed system.

System Characteristics

Scalability reflects the ability of a system to adapt to changing demands and increase its capacity.
A fundamental aspect of openness is the ability of a system to be modified, extended, or integrated with other systems.
