A vlan can span multiple interconnected switches.
<h3>
What is a vlan?</h3>
A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group.
A LAN is a group of computers or other devices in the same place -- e.g., the same building or campus -- that share the same physical network.
Each virtual switch, or VLAN, is simply a number assigned to each switch port.
For example, the two switch ports in the red mini-switch might be assigned to VLAN #10 . The two ports in the orange mini-switch might be assigned to VLAN #20 .
VLANs can be used for different groups of users, departments, functions, etc., without needing to be in the same geographical area.
VLANs can help reduce IT cost, improve network security and performance, provide easier management, as well as ensuring network flexibility.

Alan Turing fathered the machines we now lovingly call computers, however it was Nicola Tesla that birthed the idea of a world-wide wireless system.
Answer:
The time elapsed is 0.017224 s
Solution:
As per the question:
Analog signal to digital bit stream conversion by Host A =64 kbps
Byte packets obtained by Host A = 56 bytes
Rate of transmission = 2 Mbps
Propagation delay = 10 ms = 0.01 s
Now,
Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.
Time taken to generate and convert all the bits into digital signal is given by;
t = 
t = 
(Since, 1 byte = 8 bits)
t = 7 ms = 0.007 s
Time Required for transmission of the packet, t':
Now, the time elapse between the bit creation and its decoding is given by:
t + t' + propagation delay= 0.007 + 
+ 0.01= 0.017224 s
