Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
Transform the TM below that accepts words over the alphabet Σ= {a, b} with an even number of
a's and b's in order that the output tape head is positioned over the first letter of the input, if the
word is accepted, and all letters a should be replaced by the letter x.
For example, for the input aabbaa the tape and head at the end should be:
[x]xbbxx
z/z,R
b/b,R
F
①
a/a,R
b/b,R
a/a, R
a/a,R
b/b.R
K
a/a,R
L
b/b,R
Given the C++ code below, create a TM that performs the same operation, i.e., given an input
over the alphabet Σ= {a, b} it prints the number of letters b in binary.
