if the wide area network (wan) is supporting converged applications like voice over internet protocol (voip) internet protocol (ip) routing lookups will be even more essential to the assurance of the network.
Understanding WAN
WAN stands for Wide Area Network is a network that is used as a network that connects between local networks. Local computer networks are not only physically adjacent to each other, but share the same group of IP addresses.
The local network can be one room, one office or even one city. While the WAN itself is a network that connects these local networks within a city, province or even between countries. The difference between WAN and LAN networks is in the type of media used. Generally local networks or LANs use similar network media.
While the WAN is connected to devices with different transmission media and protocols. The WAN coverage area is also very wide, but unites the network as if it were in one room. WAN networks have lower data transfer rates than local networks or LANs. WAN network technology relies on companies providing long-distance telecommunications services. WAN networks use many kinds of network technologies with a mix of analog and digital signals for data transmission. Of course this is different from a local network or LAN which uses a connection between computers that are physically connected to each other with the same protocol and transmission media. The components in the WAN and their functions will be discussed later.

Answer:
int1=int(input("Enter integer :\n"))#taking input of first number.
int2=float(input("Enter the power :\n"))#taking input of the power.
if int2 == 0.5 and int1<0:#condition for negative square root.
print("Cannot calculate the square root of negative numbers")#printing the message.
else:#else calculating the result.
res=int1**int2
print(res)
output:-
Enter integer :
-5
Enter the power :
0.5
Cannot calculate the square root of negative numbers
Explanation:
In the above program I have taken input of the number and the power.Since power can be decimal number taking it as float.If the number is negative and the power is 0.5 then printing the message for not calculating the value else calculating the value and storing it in the res printing the res.
Answer:
Following are the correct python code to this question:
n1 = float(input('Input first number: '))#input first number
n2 = float(input('Input second number: '))#input second number
n3 = float(input('Input third number: '))#input third number
n4 = float(input('Input fourth number: '))#input fourth number
average = (n1+n2+n3+n4)/4 #calculate input number average
product = n1*n2*n3*n4 # calculate input number product
print('product: {:.0f} average: {:.0f}'.format(round(product),round(average))) #print product and average using round function
print('product: {:.3f} average: {:.3f}'.format(product,average)) #print product and average value
Output:
Please find the attachment.
Explanation:
The description of the above python code can be defined as follows:
- In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
- In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
- In the last line, the print method is used, which prints its variable value by using a round and format method.
Answer:
select sum(HoursWorked)
from OWNER
where ExperienceLevel <> 'Junior'
group by ExperienceLevel
having count(*) >= 3
Explanation:
First use the sum function on HoursWorked column of OWNER table. Then put the required condition of not including employees with experience level of Junior. And then use group by function to bulk the results by experience level and group only results with equal to or more than 3 records.
