What type of socket is used to install system memory
No you can't. Your system memory is something completely different than the memory used by USB Drive.
It was probably used when they had to measure land, tell time, negotiate a barter deal, or count stuff.
The XDDR is a memory format. It is a format that can be used for both graphic and system memory.
Computers operate best when they have "system memory" free and are not relying on virtual memory (which uses a hard drive as additional system memory). If you have a system with 1GB of installed system memory, and you are using 1.25GB of allocated memory, then freeing up 0.25GB of used system memory would improve performance by reducing virtual memory usage. Conversely, if you have 2.0GB of installed memory, and you are using 1.25GB of allocated memory, then freeing 0.25GB of used memory would have no appreciable effect since virtual memory is not being used by the system. Final answer: If you are using virtual memory, then freeing enough memory to eliminate the virtual memory usage will improve performance, but freeing up more than that amount will have no appreciable effect.
Minoans' writing and counting system was actually a decimal system. Their writing system used pictographs written' on clay tablets to stand for sounds in words. To count they used a decimal system based on the number 10!
