O 46°
O 600°
O 100⁰
O 4º
Answer:
I will go for 4°
Explanation:
i hope this helps
Answer: 4º
Explanation: A 600mm lens will have a field of view of approximately 4°. The field of view of a lens is determined by the focal length of the lens and the size of the film or image sensor. A longer focal length lens will have a narrower field of view, while a shorter focal length lens will have a wider field of view. 600mm is a very long focal length, so the field of view will be correspondingly narrow.

An intruder transmitting packets from the outside with a source ip address field containing an address of an internal host is known as ip address SPOOFING.
The Dangers of IP Address SpoofingIP address spoofing is a malicious practice that puts computer networks and users at risk. It occurs when an intruder transmits packets from the outside with a source IP address field containing an address of an internal host. This technique is used to gain unauthorized access to a network, hide the true identity of the sender, and even launch a denial-of-service attack. As a result, it is important to understand what IP address spoofing is, how it works, and the security measures that can be taken to protect oneself from it.
First, it is important to understand what IP spoofing is and how it works. IP spoofing is essentially a type of network attack where the attacker modifies the source address of an IP packet to make it appear as though the packet originated from a different source. This is done by changing the origin of the packet to the internal address of another user on the network, allowing the attacker to gain access to the network and perform malicious activities. The intruder can then use this access to steal information, launch a denial of service attack, or even gain control of the network.

How do firewall work?A firewall is a piece of network security equipment that keeps an eye on both incoming and outgoing network traffic and allows or denies data packets in accordance with a set of security rules. Its goal is to create a physical barrier between your internal network and incoming traffic from outside sources (like the internet), blocking unwanted traffic like that of hackers and viruses.In order to stop attacks, firewalls thoroughly examine incoming communication in accordance with pre-established criteria and filter traffic from untrusted or dubious sources. Firewalls monitor traffic at a computer's ports, which are the entry points via which data is shared with external devices. Such a statement might read, "Source address 172.18.1.1 is allowed to reach destination 172.18.2.1 through port 22."Consider port numbers as the rooms in the home and IP addresses as the houses. It is further filtered such that persons inside the house are only permitted to access specific rooms (destination ports), depending on whether they are the owner, a child, or a visitor. Only trusted people (source addresses) are allowed to enter the house (destination address) at all.

Q 1: Write a function to measure the amortized cost of appending for Python’s list class.
Q 2: Write functions for two primary operations in the Queue enqueue ( ) and dequeue ( ).
Answer:
Q 1:
import time
def measure_amortized_cost_of_appending(num_iterations):
# Create an empty list
lst = []
# Start a timer
start_time = time.perf_counter()
# Append num_iterations elements to the list
for i in range(num_iterations):
lst.append(i)
# End the timer
end_time = time.perf_counter()
# Calculate and return the amortized cost of appending
return (end_time - start_time) / num_iterations
This function creates an empty list, starts a timer, appends num_iterations elements to the list, and ends the timer. It then calculates and returns the amortized cost of appending by dividing the elapsed time by the number of iterations.
Q 2:
class Queue:
def __init__(self):
self.items = []
def enqueue(self, item):
self.items.append(item)
def dequeue(self):
return self.items.pop(0)
This implementation of the Queue class uses a Python list to store the items in the queue. The enqueue method appends an item to the end of the list, and the dequeue method removes and returns the item at the front of the list (index 0).

A dedicated server responds to client service requests in a client-server network. Client and server responsibilities are not shared by all network hosts.
Computers in a peer-to-peer network are linked via a network and can share resources. Depending on the nature of the transaction and the resources utilized or requested, each host can behave as either a server or a client. In a hybrid network, a server provides index information that allows a peer to locate resources on other peers. Depending on the nature of the network transaction, the peers can still play the client or server role.

The Flatten Image option can be used to combine all layers in a file, regardless of the number of layers.
What is Flatten Image?Combining all layers that are visible into the backdrop layer to minimize file size When flattening an image in Photoshop, all layers are simply combined into one layer. When file size needs to be reduced or before saving the file for another use, this is frequently done. The ability to modify individual layers is lost when an image is flattened. The menu button may be found on the layers window tab, which is one of the quickest methods. Select Flatten Image from the menu that appears after clicking the menu button. Flattened copy, often referred to as embedded, expanded, or outlined text/copy, is text that has been converted into an object when a digital asset, such as a JPEG, PNG, GIF, or occasionally a PDF file, is exported from the software that created it.To learn more about Flatten Image refer to:
