Write a python program to read four numbers (representing the four octets of an IP) and print the next five IP addresses. Be sur

sdas [7]

Answer:

first_octet = int(input("Enter the first octet: "))

second_octet = int(input("Enter the second octet: "))

third_octet = int(input("Enter the third octet: "))

forth_octet = int(input("Enter the forth octet: "))

octet_start = forth_octet + 1

octet_end = forth_octet + 6

if (1 <= first_octet <= 255) and (0 <= second_octet <= 255) and (0 <= third_octet <= 255) and (0 <= forth_octet <= 255):

for ip in range(octet_start, octet_end):

forth_octet = forth_octet + 1

if forth_octet > 255:

forth_octet = (forth_octet % 255) - 1

third_octet = third_octet + 1

if third_octet > 255:

third_octet = (third_octet % 255) - 1

second_octet = second_octet + 1

if second_octet > 255:

second_octet = (second_octet % 255) - 1

first_octet = first_octet + 1

if first_octet > 255:

print("No more available IP!")

break

print(str(first_octet) + "." + str(second_octet) + "." + str(third_octet) + "." + str(forth_octet))

else:

print("Invalid input!")

Explanation:

- Ask the user for the octets

- Initialize the start and end points of the loop, since we will be printing next 5 IP range is set accordingly

- Check if the octets meet the restrictions

- Inside the loop, increase the forth octet by 1 on each iteration

- Check if octets reach the limit - 255, if they are greater than 255, calculate the mod and subtract 1. Then increase the previous octet by 1.

For example, if the input is: 1. 1. 20. 255, next ones will be:

1. 1. 21. 0

1. 1. 21. 1

1. 1. 21. 2

1. 1. 21. 3

1. 1. 21. 4

There is an exception for the first octet, if it reaches 255 and others also reach 255, this means there are no IP available.

- Print the result

Sequential and direct access are two methods to locate data in memory. Discuss why major devices now a days use direct access? H

djverab [1.8K]

Answer:

Direct data access reduces the speed of retrieving data from memory or storage. Retrieving data and storing it in a cache memory provides direct access to data in the storage.

Explanation:

Sequential memory access, as the name implies, goes through the memory length location in search of the specified data. Direct memory access, provides a memory location index for direct retrieval of data.

Examples of direct and sequential memory access are RAM and tapes respectively. Data in sequential memory access can be access directly by getting data in advance and storing them in cache memory for direct access by the processor.

True or false: offset printing has more expensive start up costs than than a digital printing system

denis-greek [22]

True Offset printing is more expensive.

Offset printing often has a longer turnaround and is more expensive to set up, so that for short print runs, the cost per unit is higher than digital printing.
