Joe claims that after updating the operating system, he is unable to use his Android phone. The technician can use one of the Perform a hard reset methods.
How does a hard reset work?The process of restoring a device to its factory-fresh state is known as a hard reset. That is to say, it deletes all data, including settings, apps, and user profiles. Before selling a computer, smartphone, or tablet, hard resets can be helpful for wiping out all data. Additionally, they come in handy when you cannot fix an operating system error.
A reset button on the back of a network home router causes the router to reboot when pressed. When you press and hold the button for five to ten seconds before releasing it, you perform a hard reset. When a router performs a hard reset, all of its settings are restored to their factory defaults.

Which of the following answers refers to a solution designed to strengthen the security of session keys
"Key stretching" in cryptography is a technique for lengthening a cryptographic key to increase its security against brute-force assaults.
What is Key stretching?Key stretching techniques are used in cryptography to increase the resources (time and sometimes space) required to test each potential key, hence boosting the security of a key that may be weak, usually a password or passphrase, against a brute-force assault. Human-generated passwords or passphrases are frequently brief or predictable enough to be cracked, but key stretching aims to thwart such assaults by making the straightforward process of trying one password candidate more challenging. In some real-world applications where the key length has been limited, key stretching enhances security by simulating a greater key length from the perspective of a brute-force attacker.
Stretching your keys can be done in a variety of ways.
One method is to use a block cypher or a cryptographic hash function repeatedly in a loop. For instance, the key schedule in the cypher may be changed so that it takes a certain amount of time to execute in applications where the key is utilised for a cypher. Another method is to employ cryptographic hash functions with high memory needs, which can be useful in thwarting attacks from opponents who are limited by memory.To know more about Key Stretching Refer to:

What is one way you can evaluate the performance of an embedded system?
A Buy another embedded system and use that.
B Sell the embedded system.
C Highlight the problems you faced with the system.
D ignore the problems you faced with the embedded system.
Answer:
Explanation:
The best way to evaluate the performance of an embedded system is to test it against a set of criteria. This can include testing it for speed, accuracy, reliability, durability, and any other criteria relevant to the application. Additionally, it is important to compare the performance of the embedded system against that of similar systems on the market to get an idea of how it performs in comparison. Testing the system in real-world scenarios can also be useful to gain an understanding of how it performs in practice. Finally, gathering feedback from users of the system can be helpful to identify any areas for improvement.
suppose on average how many users are active simultaneously? (3 pts.) if each user transmits 10 percent of the time. will the answer in part (d) increase or decrease? why?users share a 10 mbps link. also, suppose each user requires 500 kbps when transmitting, but each user transmits only 5 percent of the time.
In first case 400 users can transmit & in second case 200 can transmit and the answer in part (d) will decrease.
What is network users?Network Users include all entities or individuals who have entered into a balancing agreement with the Balancing Operator.
A network user is a customer or a potential customer of a transmission system operator, as well as the transmission system operators themselves insofar as they are required to carry out their transmission-related functions.
Each user requires 500 kbps
Link is 10 Mbps = 10000 kbps
Total users = 10000/500 = 20
20 when all require 100% of time.
Now each user needs 5% of time only.
So it means 20 × 20 = 400 users can be accommodated.
For 10 percent of time then time is distributed in 10 slots.
As it was in 5% only 20 slots of times was there.
In each slot 20 users can be accommodated.
So here 10 ×20 =200 users can transmit.
The answer will decrease because here time taken by user will be more.
Thus, In first case 400 users can transmit & in second case 200 can transmit.
