A distributed computer system consists of multiple software components that are on multiple computers, but run as a single system. The computers that are in a distributed system can be physically close together and connected by a local network, or they can be geographically distant and connected by a wide area network. A distributed system can consist of any number of possible configurations, such as mainframes, personal computers, workstations, minicomputers, and so on. The goal of distributed computing is to make such a network work as a single computer.
1 Explain architecture of Distributed Database systems? Also, explain the reasons for building distributed database systems?
Distributed Software engineering is combination of distributed system engineering and distributed system architecture For more detail you need to go through the following topics 1)Distributed systems issues 2)Client-server computing 3)Architectural patterns for distributed systems 4)Software as a service
Redundancy means duplicacy of data or repetitive data. In distributed database case the data is stored in different systems . So the answers is yes there can be redundancy of records / data.In distributed database , data is stored in different systems. Since the data is distributed there is redundancy of records.
HIGH AVAILABILITY provided by Fault Tolerant Computing Systems & Networks which might be geographically distributed and thus overcomes Single Point of Failurein mission critical applications is the main goal of Distributed Computing.
In computer science, consistency models are used in distributed systems like distributed shared memory systems or distributed data stores (such as a filesystems, databases, optimistic replication systems or Web caching). The system supports a given model if operations on memory follow specific rules.I hope this helps!

Distributed Systems Technology Centre was created in 1992.
Information systems using a mainframe are referred to as distributed because computing results must be distributed to users at various locations.

Mainframe systems use dumb terminals, a client/server environment uses intelligent terminals. Cross-platform computing and distributed processing is supported in client/server architecture, but not possible in a mainframe. There can be any numbers of servers and clients in a CSA, while mainframes work on the principle of the central server.
A distributed computing system requires each machine attached to the network to has specific software allowing them to talk to each other. A distributed virtual systems allows the machines on a network to talk to each other without the use of central software.

Distributed databases offer advantages such as improved scalability, increased availability, and better fault tolerance compared to centralized databases. They also provide better performance by reducing network latency and enabling data to be processed closer to where it is needed. Additionally, distributed databases can offer better data security by replicating data across multiple locations.
