Transparencies & Types of Distributed Computing

What does Access Transparency in distributed systems aim to hide?

• The location of objects

• Differences in data representation and access methods

• The fact that an object may move to another location

• The replication of objects

In a cloud storage system like Google Drive, what aspect does Access Transparency hide from users?

• The fact that files are replicated

• The underlying data storage format and access mechanisms

• The physical location of servers

• The location of files within the cloud system

What is a key characteristic of achieving Location Transparency?

• Assigning logical names to resources

• Secretly encoding resource locations in names

• Keeping resource names identical across replicas

• Revealing the actual physical location of resources

Which scenario illustrates Relocation Transparency in action?

• Moving a file to a different folder within the same server

• Relocating a running process to another server without interrupting its operation

• Changing the format of a document without notifying users

• Replicating a database for fault tolerance

Why is it necessary for all replicas to have the same name in Replication Transparency?

• To confuse users about the location of replicas

• To achieve Concurrency Transparency

• To hide the fact that several copies of a resource exist

• To support Migration Transparency

What does Concurrency Transparency aim to achieve in distributed systems?

• Hiding differences in data representation

• Ensuring users are aware of concurrent edits

• Allowing concurrent access to shared resources without conflicts

• Revealing the physical location of objects

How does Failure Transparency work in distributed systems?

• Users are notified of failures immediately

• Users are shielded from the failure and automatic recovery occurs

• Users have to manually recover from system failures

• Failures are visible but not recoverable

Which type of distributed computing involves pooling resources from different networks or organizations to work on a common task?

• Cluster Computing

• Grid Computing

• Cloud Computing

• Parallel Computing

What is a key characteristic of Cloud Computing?

• Single-purpose clusters

• Resource sharing based on demand

• High-performance computing nodes

• Geographically dispersed resources

What distinguishes Cluster Computing from Grid Computing?

• Resource sharing based on demand

• Use of multiple interconnected computers working together

• Geographically dispersed resources

• Single-purpose clusters
