1.
• Five advantages are Incremental growth; computing power can be added in small increments.
• Reliability; if one machine crashes, the system as whole can still survive.
• Speed; a distributed system may have more total computing power than a mainframe.
• Open system; an open system is open to communicate with other systems. And open system that scales has an advantage over a closed and self-contained economic system.
2. Middleware in the context of distributed application is software that provides services beyond those provided by the operating system to enable the various components of a distributed system to communicate and manage data.

7. Domain experience, platform experience, programming language experience, problem solving ability, educational background, communication ability, adaptability, attitude, personality.
8. Remote procedure calls procedural communication in a distributed system is implemented using remote procedure calls. In a remote procedure call, one component calls another component as if it was a local procedure or method. The middleware in the system intercepts this call and passes it to a remote component. This carries out the required computation and, via the middleware, returns the result to the calling component.
