Distributed Memory Architecture
- every separate computer is usually called a node
- each node has its own memory, totally separate from all the other nodes
- each node runs a separate copy of the operating system
|the number of whiteboards (i.e. the total memory) grows as we add more offices||if we have large amounts of data, we have to decide how to split it up across all the different offices|
|there is no overcrowding so every worker has easy access to a whiteboard||we need to have lots of separate copies of the operating system|
|we can, in principle, add as many workers as we want provided the telephone network can cope.||it is more difficult to communicate with each other as you cannot see each others whiteboards so you have to make a phone call|
