Questão
Bridges
Responda
-
is the area where the computer stores or remembers data.
-

Questão 5
Questão
Cores
Responda
-
Manage how data and instructions are transferred
-
is the time for components to respond to a request
-
communicate through channels therefore doubling cores does not double speed

-
less data can be stored closer to the CPU
-
more data can be stored closer to the CPU
Questão 15
Questão
The clock speed - also known as clock rate -
Responda
-
depends on the size of the cache
-
indicates how fast the CPU can run.
-
stores programs, data and instructions.
-
allows the communication between devices
