Answer:

Liam could

1) Change the password

Be sure to change the password to a "strong" one (containing lots of characters, numbers, symbols) so that way the password would be difficult to guess.

2) Avoid logging onto social media on public computers or WiFi connections.

Using public WiFi leaves you vulnerable to someone accessing your information through Internet traffic. If you do use public computers, just make sure to log out.

3) Avoid giving out account information to friends and avoid opening suspicious links and emails.

Opening suspicious links or emails could allow malware to infect your computer the moment you open them. Friends can unknowingly share these links that are designed to steal information.

I hope this helped <3 please lmk if there's anything more to add.

When studying an information system, illustrations of actual documents should be collected using a process called _____.

Oliga [24]

When studying an information system, illustrations of actual documents should be collected using a process called sampling. Correct answer: D
This process systematically selects representative elements of a population with the goal to get representative and useful information about the population as a whole and it is useful when data sets that are too large to efficiently analyze in full.

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

Which of the following Python methods in scipy.stats submodule returns the P-value for performing a hypothesis test for the sign

ipn [44]

Answer:

Option B is the correct answer for the following question.

Explanation:

The following option is true because the pearsonr from scipy module is the method of the Python Programming Language in the submodule i.e., "scipy.stats" which print or return P-value for operating the hypothesis test for the value of correlation coefficient. So, that's why the following option is correct.

avanturin [10]

I found that,

On the basis of Model, computer is classified as: XT Computer (Extra Technology): It cannot support GUI based operating system. Its processing speed is 4.77 MHz and Intel 8080, 8086, 8088 series of microprocessors is used. PS/2 Computer: It is a laptop computer which is rechargeable and battery based system.
