2. Each type of bus contains the same basic transactional elements and pipelining architecture.
a. true
b. false
3. Which is a more efficient way to remove a chunk of data?

b. false
5. With the P6-family of processors, bus realignment may be achieved by active analysis probes.
a. true
b. false
6. Which is the correct triggering sequence?
