hello all. i want to ask a question that we all know that smartphones has ram processors in it bt there are many other phones which are just simple phones or some java based e.g samsung e 1080t or nokia c1 or x2. how do these mobiles work without ram and processors and if they have y it is not mentioned in specs? i mean how these mobile works

of course they have a processor and RAM. there's really no difference other than the operating system used.

then y its not mentioned anywhere

Simple phones are not designed to be running user apps so they don't need to specify specs since they know all the current software will run perfectly. This is not the case with "smartphones" that can run user applications that may consum alot of power.

A low-end phone may use a SOC or "System on a chip". This is a custom dsigned chip containing the processor, the ram, the IO controls, everything. Expensive to design but cheap to produce in large quantities.

The N900 has an omap3 SOC too.

Even for "smartphones" there should be no need to specify the CPU, RAM or any other architectural details. As long as you can install "apps" and they run, then it's OK.

But of course with the added flexibility of installing lots of applications and, especially, multi-tasking, CPU/RAM becomes a useful factor for comparing phones, and that's why you see it in the specs.
