Distributed Operating System (DOS)
In computing, a distributed system is a system that works in different locations or work using separate processing or processors to their jobs, often simultaneously. Data can be stored in different locations in a distributed database, although a user won't know it. The data will appear on their screen when they access, so they are unaware of its location. Networks use distributed systems to link up systems that work together but are in separate locations. If there are full copies of data in various locations, then if one location gets damaged or inaccessible, the system can still function. This makes data and systems more secure.
On a computer network, operating systems communicate with each other. In a distributed operating system, a single OS is communicating with itself across multiple machines.
eCos is a free and open-source real time operating system intended for embedded applications and systems which need only one process with multiple threads. It is designed to be customisable.

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.

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.
Grid Computing and Distributed 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
POSIX threads are user level threads, because had a interface library and the operating systems don't control his ejecution and does not know
Distributed systems refer to a network of independent computers that work together to achieve a common goal, while distributed database systems specifically involve databases that are spread across multiple locations. Distributed database systems focus on storing and managing data across various nodes in a network, whereas distributed systems are more general and encompass a broader range of functionalities beyond data management.
