True of False:

1)Suppose bit error rate is 10^-8 and the length of a packet is 10000 bits. Assume bit errors happen independently. Then the probability that a single bit error happens in this packet after a transmission is approximately 10^-4

²⁾Under Poisson traffic, continuous-time ALOHA has higher throughput efficiency than slotted ALOHA

3)In the OSI reference model, a network layer protocol is point-to-point, i.e., the protocol will work at every intermediate router along the path from the source to the destination.

4)If the minimum Hamming distance of an error correction coding scheme is 7, then this coding scheme can detect up to 6 bit errors and can correct up to 4 bit errors.

5)In go-back-N ARQ protocol, the Receive Window Size (RWS) equals to 1.

6)DNS (domain name service) is an application layer protocol.
