Answer:
C. A cold site is a leased facility that contains only electrical and communications wiring, air conditioning, plumbing, and raised flooring. No communications equipment, networking hardware, or computers are installed at a cold site until it is necessary to bring the site to full operation.
Explanation:
Answer:
Towers and satellite.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.
The distance from one peak to the next peak is called wavelength. This distance is also equal to the distance from one trough of a wave to another.
Also, microwave is a form of radio waves which typically has short wavelengths and frequency ranging from 300 MHz and 300 GHz.
Hence, microwave transmits information between network nodes using towers and satellite.
Answer:
See explaination
Explanation:
a.
myString is "Hello the world"
b.
prints "15"
c.
This is invalid.
We have to use strcpy_s to copy strings
FIX:
strcpy_s(s,"Marylane");
d.
reading string upto length 80 from the user and stored it in myString variable
e.
prints the string enetered by user to console
f.
replacing 7th character by 't'
Classes have three areas, (public, private and protected)
"public <span>area" of a class is accessible to all entities that can "see" the object(s) of that class type (accessible in and out)
</span>"private area" of a class is accessible to only within that class, i.e. cannot access them from outside the class (accessible in)
"protected area" of a class is accessible to all entities that can "see" the object(s) of that class type (accessible in and "out with some conditions")
Answer:
value=int(input("Enter the value from where the user wants to starts: "))#Take the value from the user.
i=1#intialize the value of a variable by 1.
while(value<1000) and (i<9):#while loop which prints the value.
print(value,end=" ")# print the value.
value=value*2#calculate the value to print.
i=i+1#calculate the value for the count.
Output:
If the user enter 5, then the output is : "5 10 20 40 80 160 320 640".
If the user enter 5, then the output is : "3 6 12 24 48 96 192 384".
Explanation:
- The above code is in python language, in which the first line of the program is used to render a message to the user, take the input from the user and store it into value variable after converting it into an integer.
- Then the loop will calculate the double value and then it prints the value with the help of print function.
- The end function puts the spaces between numbers.
