As was stated earlier, it depends. For a workstation setup (basically one/two users logged on at a time), a total of 250-300MB of RAM and swap is usually quite enough. For a server with lots of simultaneous usage may need 1 GB swap partition. A swap partition is a form of virtual memory. Because it resides on a drive, it is slower than physical RAM. Linux tries to make as much use of available RAM as possible, including using it for cache processes. It will spill over to a swap partition as needed, but understands the speed limitations of swap. Linux does manage memory resources very well.
