3. Concurrency: concurrent execution of the processes, high performance, optimum rate of price and performance
4. Fault tolerance: ability to tolerate the fault of system units, availability (using potential redundancy to overcome the system fault).
5. Transparency: a distributed system can be looked as one computer (access transparency, position transparency, parallel transparency,....)
6. Scalability: can solve larger problems without larger computers
7. Openness and heterogeneity: applications and data may be difficult to relocate and reconfigure
