This laptop comes equipped with 2 GB of PC1066 DDR2 RAM. As for ROM, that's hard to say; you'd have to add-up the SRAM modules off each of its individual components and whatever disk is in the optical drive. The answer doesn't have any bearing on performance or ability, however, since by definition, ROM is read-only.
If I was to purchase a computer that is a average desktop computer how much RAM and Rom should I have?

The BIOS is stored on ROM.
ROM isn't erased when you turn the power off, whereas RAM is.
RAM is a volatile Memory. But ROM is not volatile.
RAM is an acronym for Random Access Memory; ROM is an acronym for Read Only Memory. Both RAM and ROM are random access; that is, each cell in memory is directly accessible. The cells in RAM can be both read from and written to. The cells in ROM can only be read from. The bit pattern in ROM is determined at the time of manufacture or burned when the computer is assembled. Once a ROM has been burned (written), it cannot be changed. Another major difference is that RAM is volatile and ROM is not. This means that RAM does not maintain its bit patterns when the power is turned off, but ROM does.
