f = open("numbers.txt", "r")
lst = [int(x) for x in f.read().splitlines()]
sum = 0
for x in lst:
----sum += x
I had to add the four dashes to maintain the structure of my code. You can replace them with spaces. Also, I wouldnt recommend having a variable named sum because python has a built in function named sum. You can test this code by putting print(sum) at the end of the code.
Answer:d)the logical grouping of activities in a business process.
Explanation: The logical data flow diagram is the diagram that displays or represents the business related activities.They has easily understandable concept which can be acknowledged by technical as well as non-technical people.They help in providing the data/information by connecting and communicating.
Other options are incorrect because it does not show the process or methods for performing activities neither it works in the form of entities collection in a business..Thus the correct option is option (d).

hope this helped :D
Answer:
Find the explanation below.
Explanation:
Asymmetric encryption is a system of communication in technology between two parties where keys which are variable values coined by an algorithm are used to encrypt and decrypt the messages between the sender and receiver. The two types of keys used in this process are the public and private keys. The public keys can be used by anyone to encrypt messages which are then sent to the receiver who decrypts the message using his private keys. The private keys on the other hand are only shared by the person who first set up the key. In sending messages this way, the receiver's public key is gotten from a public directory, and the message encrypted by the sender. The receiver can then decrypt the message using his private keys. But if the message is encrypted using a private key, it is decrypted by the receiver with a public key.
The one-way nature of this style of communication ensures data integrity and confidentiality since users are not required to disclose their keys and only the two parties can access the message. The two end users also preserve the right to authenticate the keys. The transport layer security protocol makes use of asymmetric encryption.
The first example is an IPv4 address. Because IPv4 is only 32 bits long there are only about 4 billion addresses available. To expand the address space IPv6 came into existence and your second example is an IPv6 address.
