8085 has 16 addr lines so it can have acess to 64k in similar way 8086 has 20 addr lines so it can access 1M..........so what about the pentium4 processor.........if it has fixed number of addr lines how can diff machines have diff values of ram?

The limitation is on the Motherboard. Most P4 motherboards will accept 4GB of RAM.
Good luck and Happy Computing!

A pentium 4, like most 32-bit processors is technically capable of accessing up to 4 GiB of RAM... Different machines can hold different capacities because they don't exceed the maximum capacity they can hold, well, that and people are slowly switching over to 64-bit archetextures now.... Basicly a 32-bit chip can only hold a max of 32-bit integers, so any integer that can't be expressed in 32 bits doesn't fit the processor, which is designed to be able to store all possible memory adresses.

Since the PIV is capable of addressing 32-bits, then it is 2^32=4GB.

The coprocessor (FPU) is used for high-precision operations instead.

its dependent on the motherboard and chipset...
may be it could accept in greater than 4 gb , recently from now

it depends oom the mother board mine pc at home holds only 2gb(p4) but at office holds 8gb(p4)
