What is the output of the following code? dl={"name":"Alex", "age":19} a= di.get("major") print(a) O Error O None O CS
Answers
The given code will output "None".
The code defines a dictionary dl with the key-value pairs "name" and "age". However, when attempting to retrieve the value associated with the key "major" using the get() method, the code is likely to encounter an error.
In the code, the variable `dl` is assigned a dictionary with key-value pairs. Then, the variable `a` is assigned the value of `di.get("major")`. However, there is no key "major" in the dictionary `dl`, so the `get()` method will return `None`. Finally, `None` is printed to the console.
The reason for the error is that the variable used to access the dictionary is incorrect. The dictionary is defined as dl, but the code attempts to access it using di. This inconsistency will result in a NameError, indicating that the variable di is not defined.
Assuming the variable is corrected to dl, the get() method will return None if the specified key ("major") is not found in the dictionary. Since "major" is not present as a key in dl, the get() method will return None.
Consequently, when attempting to print the value of a, which is the result of the get() method, the output will be "None".

consider two hosts, a and b, connected by a single link of rate r bps. suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. host a is to send a packet of size l bits to host b.
Answers
In a scenario where two hosts, A and B, are connected by a single link with a rate of r bps, and they are separated by a distance of m meters, the propagation speed along the link is s meters/sec. Host A needs to transmit a packet of size l bits to Host B.
To understand the time it takes for Host A to transmit a packet to Host B, we need to consider both the transmission time and the propagation delay. The transmission time is determined by the size of the packet and the rate of the link, while the propagation delay is influenced by the distance between the hosts and the propagation speed. The transmission time can be calculated using the formula: Transmission Time = Packet Size / Transmission Rate. This represents the time it takes to physically transmit the packet over the link. On the other hand, the propagation delay is the time it takes for a bit to travel from one end of the link to the other. It can be calculated as Propagation Delay = Distance / Propagation Speed.

Does anybody know if I can get back deleted photos but the thing is I accidentally deleted my back up so is there any other way I can get it back without a back up??
Answers
Answer:
Explanation:
Here are some general tips that will help you recover deleted photos:
I am aware that you checked the back up however assuming your device has it Check the "Recently Deleted" or "Trash" folder
Use data recovery software: Data recovery software is available for a variety of operating systems, including Windows, macOS, Android, and iOS, and can assist you in recovering deleted photos. This app searches the storage of your device for evidence of deleted data and attempts to recover them.
If you are unable to retrieve your deleted images using software, you should consider hiring a professional data recovery agency. These services use specialized techniques and experience to recover data from a variety of devices and storage media.
Stop using the device immediately after realizing the photographs have been destroyed to avoid overwriting them and decreasing the possibilities of recovery. Take no new images or save any new data to the device until you've tried data recovery.
It should be understood that the success rate of restoring deleted photographs without a backup varies and is not guaranteed. It's always a good idea to back up your vital data on a regular basis to avoid losing photos in the future.
All the best, I hope you find your photos.

Patch cables often consist of coaxial cable, although they can also be comprised of fibre optics, CAT5/5e/6/6A, shielded or unshielded wires, or single-conductor wires. Patch cables are never permanent solutions because they always have connectors on both ends, unlike pigtails or blunt patch cords.

poe+ devices are defined by what ieee standard
Answers
PoE+ devices are defined by the IEEE 802.3at standard.
The IEEE 802.3at standard, also known as PoE+ (Power over Ethernet Plus), is an extension of the original PoE standard (IEEE 802.3af). It provides a higher power delivery capability to network devices over Ethernet cables. PoE+ allows for the delivery of up to 30 watts of power, compared to the 15.4 watts provided by the standard PoE.
PoE+ is designed to support power-hungry devices such as IP cameras, wireless access points, VoIP phones, and other network devices that require more power for their operation. By providing higher power levels, PoE+ enables the deployment of a wider range of devices that can be powered and connected through Ethernet cables, eliminating the need for separate power supplies.
Devices compliant with the PoE+ standard can receive power and data over the same Ethernet cable, simplifying installation and reducing the need for additional power outlets. The IEEE 802.3at standard ensures compatibility and interoperability between PoE+ devices from different manufacturers.

Eldar has found a sequence of lightning: On the 1st second controller lights ON all LED lamps . ( 1 .... 2 ... 3 .....) On the 2nd it lights ON the LEDs that are even in the circuit. ( 2 ... 4 ... 6 .... ) On 3rd second it lights every third LED in the circuit. ( 3...6...9...) And so it continues in similar way... Which LEDs must be switched ON after the 16th second
Answers
Answer:
Non of the LED lamps present will be switched on after the 16th second
Explanation:
From the question, the operation of the controller with time are;
The LED lamp the controller lights up on the 1st second = All LED lamps
The LED lamps the controller lights up on the 2nd second = All even numbered LED lamps = Every other lamp with a number which is a multiple of 2
The LED lamps the controller lights up on the 3rd second = Every other LED lamp with a number which is a multiple of 3
Given that the LED lamps continues in that way, the LED lamps the controller lights up on the 16th = The 16th LED lamp which is a multiple of 16
Therefore, the LED lamp(s) the controller lights up after the 16th second = The 17th or more LED lamp = Non of the LED lamps present will be switched on after the 16th second
