3rd Quiz Distributed Processing and Distributed Databases

main characteristic of distributed processing

• Shares logical processing among multiple sites

• Processes data in a single location

• Does not utilize a network

• Requires a centralized database server

What does "database fragment" refer to in a distributed database

• A single point of failure

• Temporary data during processing

• A subset stored at different sites.

• A complete backup of the database

key advantage of distributed processing

• Reduced network needs

• Centralized data management

• Increased reliance on a single server

• Improved performance through parallel execution

essential for managing tasks in distributed processing

• Local file storage

• Distribution management software

• Single user interface

• Centralized database

What role does the network play in these systems

• Connects independent computing resources

• Centralizes operations.

• Limits access to one site at a time

• Prevents data replication

NOT a feature of distributed databases

• Managed by local processes

• Centralized control

• Data replication

• Logical distribution of fragments

challenge of distributed processing

• Increased speed of access

• Simplified execution

• System coordination and load balancing

• Enhanced fault tolerance

How does parallel processing benefit distributed systems

• Limits node involvement.

• Centralizes all resources.

• Tasks must be completed sequentially

• Divides tasks into subtasks

Why replicate database fragments in a distributed system

• limit access to specific users

• improve availability and fault tolerance

• reduce overall database size

• ensure all fragments are identical at every site

primary goal of using distributed systems

• Enhance performance, scalability, and reliability

• Centralize control over operations

• Minimize the number of computers used

• Limit accessibility to specific users
