In modern computer systems, a byte consists of [blank_start]8[blank_end] bits.
Questão 11
Questão
RAM, random-access memory, is called that because
Responda
-
it is optimized for random number processing.
-
accesses are randomized to prevent clogging the control lines.
-
you can pick any two random locations and it will take the same time to access the data.
-
when power is turned off, its contents are lost and replaced by random bits.
-
none of the above.
