209012 2004-01-21 14:42:00 I got a question
cellphone colours is written in k but windows is in bits.
Whats the difference?How many colours can windows display?

Edo ram is measured in nano seconds.Sd ram is measured in mhz.
Is time faster than speed?or the other way around?

209013 2004-01-21 17:49:00 well you could represent puter colours in 'k' too for example 16bit = 64k drcspy (146)

The number of bits can be converted to # of colurs by:

2^bits = # colours (where ^ is the power function).

eg 2^16 = 65536 = 64K.

They are two different measures. Nano seconds is the latency of the memory. While MHz measures the clock rate of the memory. EDO ram still has a clock rate, and sdram still has a latency.

The clock rate gives you the _peak_ theoretical data rate of the memory (when multiplied by the bus width which is why DDR ram is advertised as either PC3200 or 400MHz DDR * 8 bit bus.), bigger = better. The latency is the time it takes to access the memory, lower = better.
