Answer:
the designer choose because it has many basic and advance feature and it is Synchronous digital hierarchy (SDH) and synchronous optical network (SONET)
refer to a group of fiber-optic transmission rates that can transport digital signals
with different capacities. And it feature is Almost all new fiber-transmission systems now being installed in public networks
use SDH or SONET. They are expected to dominate transmission for decades to
come, just as their predecessor PDH has dominated transmission for more than
20 years (and still does in terms of total systems installed). Bit rates in long-haul
systems are expected to rise to 40 Gbps soon after the year 2000, at the same
time as systems of 155 Mbps and below penetrate more deeply into access
networks.
2 they choose Because of these problems, the big cable networks use hybrid fiber-coax networks. The use of fiber increases the upstream bandwidth and reduces noise, making it easier for upstream data to reach its destination. But upgrading to hybrid fiber-coax is hugely expensive.
Answer:
student_file = {}
endf_input = '1'
for x in iter(list, 1):
name = input("Enter a student name: ")
st_id = int(input("Enter a student id number: "))
student_file[name] = st_id
endf_input = input("Add more student to file (type 1 for yes and 0 to end): ")
if endf_input == '0':
break
print("Search for Student")
search = int(input("Enter student id: "))
if search == 0:
print("Sorry, no student with id of zero.")
quit()
for key, value in student_file.items():
if value == search:
print(f"Student name: {key}")
Explanation:
The program source code uses a for loop to continuously add data to the student file dictionary structure but breaks from the loop when a zero is received as input. The program enters search mode and returns the name of the student with the searched id number.

A.
Not B because a guitar has no moving parts.
Not C because guitars receive all the power they need from a cord.
And not D because a guitar is not a car and doesn't need to move!
Answer:
Explanation:
The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.
def in_values():
num_list = []
while True:
try:
num = input("Input non-zero floating point: ")
num = int(num)
if num == 0:
break
else:
num_list.append(num)
except ValueError:
print("No valid integer! Please try again ...")
try:
num = input("Input non-zero floating point: ")
num = int(num)
break
except ValueError:
break
sum = 0
for number in num_list:
sum += number
return sum
