Twenty hosts are connected to a hub. Host A sends a unicast message to Host B. Which of the following is not true?
A. Only Host B opens and processes the message.
B. All hosts receive the message.
C. All hosts open and process the message.
D. The destination address field holds Host B’s MAC address.
Homework Answers
C is correct. Only the host that the unicast message is addressed to will open and process the message.
A, B, and D are incorrect. All hosts receive the message since they are all connected to a Layer 1 device. Only Host B will open and process the message since the destination address field matches its MAC address.

Host A and Host B are connected to the same switch, and Host A sends a message to Host B. When the switch starts receiving the bits, it reads the destination MAC address, determines the port Host B is on, and immediately opens a channel to that port while bits are still being received. Which switch mode is being used? A. Cut through B. Store and forward C. Fragment free D. Full duplex

Hosts A through J have been connected to a switch for some time, with Host A on port 1, Host B on port 2, and so on. A user moves his system and connects Host A to interface 12. Immediately after the connection, Host A sends a unicast message to Host B. Which of the following are true? A. When the frame enters the switch, it is flooded to all interfaces. B. When the frame enters the switch, it is...

Hosts A and B are communicating over a TCP connection, and Host B has already received from A all bytes up to and including byte 1029. Suppose Host A then sends three segments to Host B back-to-back. The first, second and third segments contain 1200, 150 and 80 bytes of data respectively. In the first segment, the sequence number is 1060, the source port number is 8080, and the destination port number is 80. Host B sends an acknowledgment whenever...

QUESTION 17 We assume that a LAN network includes 7 hosts (A, B, C, D, E. Fand G) which are connected by a switch. The contents of the switch's CAM table is as follows: (Port 1. Host A) - (Port 2. Host B) - (Port 3. Host - Port 4, Host D) - Port S. Hosta-Port 6, Host F) - (Port 7. HostG), Also, we assume that there is/are one or many host(s) that has/have sent fake...

In the network shown below, nodes A through G are hosts, node H is an Ethernet hub. node S is an Ethernet switch. Host G acts as an IP-level router (i.e. a gateway) between the two subnets. Subnet 1 is allocated IP block 197.15.35.0/24. and Subnet! is allocated IP block 200.40.1 S. 192/26. All of the network interfaces in Subnet 1 were manufactured by Intel. All of the network interfaces in Subnet2 were manufactured by Apple. Suppose a DXS resolver...

I just need some help understanding this problem. Pointing in the right direction would be very helpful. C++ in a UNIX Environment Part1 Create a one-directional ring of pipe for N processes (N ≥ 1) Part2 Create a one-directional ring of pipe for N threads Part3 Create a one-directional ring of socket for N hosts (or all in one). You may run N processes in one host. Each process has two designated ports - one for sending and...
