Study Notes

Parallel computing uses multiple processors to perform tasks simultaneously.
Memory in parallel systems can be shared or distributed.
Distributed computing uses multiple autonomous computers that communicate through message passing.
Parallel computing saves time and money and can handle larger problems.
Bit-level, instruction-level, and task parallelism are types of parallelism.
Client/server and peer-to-peer systems are types of distributed systems.
Distributed systems allow for easy data sharing and scalability.
Adequate security and potential data loss are disadvantages of distributed systems.
Virtualization allows for sharing of a physical resource among multiple organizations.
Virtualization assigns a logical name to a physical resource and provides a pointer when demanded.
