Answer:

Explanation:

There are various safety features in place to prevent such scenarios from happening. For starters phones usually have a pin code, pattern code, or fingerprint scanner which prevents unauthorized individuals from entering into the phone's services. Assuming that these features have been disabled by the phone's owner, payment applications usually require 2FA verification which requires two forms of approval such as email approval and fingerprint scanner in order for any transactions to go through. Therefore, an unauthorized individual would not have access to such features and would not be able to complete any transactions.

I'd suggest he uses LOOKUP Function.

You can use the LOOKUP function when you need to look in a single column or row and find a value from the same position in a corresponding column or row. We have a much improved VLOOKUP that can also be used to search one row or column or multiple rows and columns.

Given the lists list1 and list2, not necessarily of the same length, create a new list consisting of alternating elements of lis

tester [92]

Answer:

The following code is written in Python Programming Language.

Program:

list1=[1,2,3]

# initialized the list type variable

list2=[4,5,6,7,8]

# initialized the list type variable

list3=[]

# initialized the empty list type variable

for j in range(max(len(list1), len(list2))): #set for loop

if j<len(list1):

#set if statement

list3.append(list1[j])

#value of list1 appends in list3

if j<len(list2):

#set if statement

list3.append(list2[j])

#value of list2 append in list3

print(list3) #print the list of list3

Output:

[1, 4, 2, 5, 3, 6, 7, 8]

Explanation:

Here, we define three list type variables "list1", "list2", "list3" and we assign value in only first two variables "list1" to [1, 2, 3] and "list2" to [4, 5, 6, 7, 8] and third list is empty.

Then, we set the for loop and pass the condition inside it we pass two if conditions, in first one we compare the list1 from variable "j" inside it the value in list1 will append in list3, and in second one we compare "j" with list two and follow the same process.

After all, we print the list of the variable "list3".

In the original UNIX operating system, a process executing in kernel mode may not be preempted. Explain why this makes (unmodifi

Elena L [17]

Answer:

the preemption is -> The ability of the operating

system to preempt or stop a currently

scheduled task in favour of a higher priority

task. The scheduling may be one of, but not

limited to, process or 1/0 scheduling etc.

Under Linux, user-space programs have always

been preemptible: the kernel interrupts user

space programs to switch to other threads,

using the regular clock tick. So, the kernel

doesn't wait for user-space programs to

explicitly release the processor (which is the

case in cooperative multitasking). This means

that an infinite loop in an user-space program

cannot block the system.

However, until 2.6 kernels, the kernel itself was

not preemtible: as soon as one thread has

entered the kernel, it could not be preempted to

execute an other thread. However, this absence

of preemption in the kernel caused several

oroblems with regard to latency and scalability.

So, kernel preemption has been introduced in

2.6 kernels, and one can enable or disable it

using the cONFIG_PREEMPT option. If

CONFIG PREEMPT is enabled, then kernel code

can be preempted everywhere, except when the

code has disabled local interrupts. An infinite

loop in the code can no longer block the entire

system. If CONFIG PREEMPT is disabled, then

the 2.4 behaviour is restored.

So it suitable for real time application. Only

difference is we don't see many coders using it
