The effective key length of Double DES, also known as 2DES, is 56 bits.
This is because Double DES applies two iterations of the Data Encryption Standard (DES) algorithm, which uses a 56-bit key. However, using two keys increases the key space to 2^112 possible keys, which makes it more difficult to crack than single DES.
However, Double DES is vulnerable to meet-in-the-middle attacks, which reduces the effective key length to 57 bits. This vulnerability arises because an attacker can precompute the encryption of a plaintext with one key and the decryption of a ciphertext with another key and store them in a table. The attacker can then compare the resulting ciphertexts and try to find a match, which reveals the two keys used for encryption and decryption.
For this reason, Double DES is no longer considered secure, and other encryption algorithms such as Triple DES and Advanced Encryption Standard (AES) are recommended for use in modern cryptography.

A programmer has a need to round many numeric values to the nearest integer. Which of the following best explains the benefit of using a list as a data abstraction in this situation
Answer:
Keeping the numeric values in a list makes it easier to apply the same computation to every data element.
Explanation:
A list or array in programming is a data structure, that has the location for each item it holds indexed. It eliminates the need to constantly create a variable to compute items of the same data types.
The list can store items of the same data type and iterate over them to compute the same calculation on each of them.
Lists are values which are seperated by commas and populated within square brackets. They are mutable and values could be easily accessed, appended, deleted or replaced. Hence, the use of a list for data abstraction is beneficial in that the round function could be easily applied to all the values in the list.
Rounding the values in the list coukd be easily done using for loop which takes each value in the list one at a time, rounds them to the nearest integer and places them into another list.
Using the a python list comprehension thus:
Given a list of numeric Values :
my_list = [1.2, 1.4, 1.5, 1.7]
rounded_int = [round(x) for x in my_list]

Choose the correct option. i) An object thrown from a moving bus is on example of
(A) Uniform circular motion
(B) Rectilinear motion
(C) Projectile motion
(D) Motion in one dimension
age
The answer is option C: "Projectile motion."
Projectile motion refers to the motion of an object that is thrown or launched into the air and follows a parabolic path under the influence of gravity. An object thrown from a moving bus is an example of projectile motion because it is launched into the air and follows a curved path due to the force of gravity.
Option A: "Uniform circular motion" refers to the motion of an object moving in a circular path at a constant speed.
Option B: "Rectilinear motion" refers to the motion of an object moving in a straight line.
Option D: "Motion in one dimension" refers to motion that occurs along a single straight line, rather than in two or three dimensions.

compared with a star topology, a hierarchical topology:
The hierarchical topology is a network topology that is divided into three different levels of hierarchy, while a star topology is a network topology that is designed using a central hub connected to various nodes.
A hierarchical topology is classified into three different levels of hierarchy. They are the core layer, the distribution layer, and the access layer. In a hierarchical topology, the access layer is connected to the distribution layer, while the distribution layer is connected to the core layer. Each layer of the hierarchical topology has its own set of functions. The core layer manages traffic between various distribution layers, the distribution layer is responsible for transmitting data between various access layers, while the access layer is responsible for controlling communication between end-users.In a star topology, all the nodes in the network are connected to a central hub. The central hub, in this case, is responsible for transmitting data between all the nodes in the network.
Comparing hierarchical topology and star topology, hierarchical topology is more scalable. A hierarchical topology is used when the network has multiple departments and a large number of computers that are present at the same location. On the other hand, a star topology is used when the network has fewer nodes and there is a lesser requirement for scalability.

An institution has obtained a subnet 100.200.0.0/16, and wants to assign smaller subnets to 4 departments that has 1000, 500, 500, and 200 computers, respectively. Divide 100.200.0.0/16 into smaller subnets to accommodate the 4 departments. Find the subnet, and the IP address of the first and last hosts in each subnet.
The subnet range would be 100.200.6.0/24, and the first and last IP addresses would be 100.200.6.1 and 100.200.6.254 respectively.
To accommodate the four departments with different number of computers, the institution can divide the subnet 100.200.0.0/16 into smaller subnets using Variable Length Subnet Mask (VLSM).
For the department with 1000 computers, it requires a subnet with at least 1024 (2^10) addresses. This can be achieved by using a /22 subnet, which would have 1024 addresses. The subnet range would be 100.200.0.0/22, and the first and last IP addresses would be 100.200.0.1 and 100.200.3.254 respectively.
For the departments with 500 computers, they require a subnet with at least 512 (2^9) addresses. This can be achieved by using a /23 subnet, which would have 512 addresses.
The two departments can share the same subnet, with a range of 100.200.4.0/23. The first and last IP addresses of this subnet would be 100.200.4.1 and 100.200.5.254 respectively.
For the department with 200 computers, it requires a subnet with at least 256 (2^8) addresses. This can be achieved by using a /24 subnet, which would have 256 addresses
By using VLSM, the institution can effectively allocate the subnets to the departments based on their specific needs, without wasting IP addresses.
