• Shared memory systems allow cores to have access to the computer's entire memory. Thus, each core can read and write to a shared memory space that all cores on the computer have access to. In a distributed memory system, each core has its own private memory, and cores have to communicate explicitly about the data in their own memory to other cores instead of the other cores having direct access to it. Everyday computers are shared memory systems, as processes inside programs all have access to the entirety of the computer's memory.

• Distributed memory systems are often in the form of networks like the internet, where users' computers have to explicitly send data to servers and vice-versa, and private data on other cores or computers are not accessible to others.
