    What is the difference between virtual and physical address?
    In a computer supporting virtual memory, the term physical address is used mostly to differentiate from a virtual address. In particular, in computers utilizing a memory management unit (MMU) to translate memory addresses, the virtual and physical addresses refer to an address before and after translation performed by the MMU, respectively.

    In Argentina, an address must be mailed this way:
    The postal code has been changed from a four digit format to an eight digit format, which is shown in the example. The new format adds a district or province letter code at the beginning, which allows it to be identified. As the system has been changed recently, the four digit format can still be used: in that case it is necessary to add the name of the province or district.
