Hi! I got a question on ranking the time needed to route data between switch, hub, router and bridge in increasing order.
Personally, I know that router takes the longest time since it is most complex and that hub takes the least time since it just floods all other ports. For switches and bridges, which takes a longer time? Also, why?
Secondly, I know that bridge are software-based while switches are hardware-based. Is there a reason for these or must I memorise these facts blindly for the exam?
Thirdly, I dont understand why TCP and IP are linked together. TCP is in the transport layer and is reliable. IP is a "best effort" protocol and is in the network layer. So why is TCP/IP lumped together?
Fourthly, I got an interest in becoming a pen-tester. What certification should I have besides CCNA? CCSP or CCNP?
Thanks. Did I post my questions in the right place?
