INTRODUCTION
WHAT IS DISTRIBUTED SYSTEM? A distributed system is a collection of independent computers connected by a network that appears to users as a single coherent system.
DB SERVER A specialized server that stores, manages, and processes databases for multiple users or applications over a network. A high-performance computer designed for a single user to perform specialized, compute-intensive tasks like graphics design or scientific computing. A server that provides centralized file storage and sharing to multiple users, managing access to files but not processing database queries. WORKSTATION FILE SERVER A high-performance computer designed for a single user to perform specialized, compute-intensive tasks like graphics design or scientific computing. WORKSTATION COMMUNICATION NETWORKS
Features of Distributed Systems Concurrency: Multiple components operate simultaneously. No Global Clock: Systems operate asynchronously Transparency: Location, access, replication transparency. Scalability: Can grow easily by adding nodes. Independent Failures: One node failure does not halt system. Resource Sharing: Users can share hardware and data. Openness: System can integrate heterogeneous hardware/software.
2 1 3 4 ADVANTAGES Efficient resource usage via sharing. Scalability for large systems. Increased fault tolerance and reliability. Flexibility to integrate diverse systems
DISADVANTAGES Difficulty in synchronization and maintaining consistency. Complexity of design, implementation, and management. Network dependency causes latency, failures affect performance. Security issues due to network exposure.
