The union of two tables is basically the total of the two tables, so "or" questions would be my guess.
<span>I would advise her to press the fn keyboard key
along with the function key with a monitor connected on it. She should ensure
that she has the correct cable to connect the laptop to the projector. Most
laptops require a manual switch by pressing these combination keys but for
some, they will automatically detect the external display and switch to video
output</span>
Answer:
1.Use passwords that can't be easily guessed, and protect your passwords.
2.Minimize storage of sensitive information.
3.Beware of scams.
4.Protect information when using the Internet and email.
5.Make sure your computer is protected with anti-virus and all necessary 6.security "patches" and updates.
7.Secure laptop computers and mobile devices at all times: Lock them up or carry them with you.
8.Shut down, lock, log off, or put your computer and other devices to sleep before leaving them unattended, and make sure they require a secure password to start up or wake-up.
9.Don't install or download unknown or unsolicited programs/apps.
Secure your area before leaving it unattended.
10.Make backup copies of files or data you are not willing to lose.
Explanation:
Answer:
a) 4 processes
b) 2 resources
c) R1: 2 instances
R2: 2 instances
d) R2
e) R1
f) R1
g) No resource
h) R1
i) R2
j) R2
k) No
l)No deadlock
Explanation:
You need to know that the resources that are required by the processes for completion are shown by the request edge and the resources allocated are shown by the allocation edge. And thus, we can find what resources are allocated to the process, and required for the completion accordingly. And here again, the cycle is created, and hence deadlock may or may not occur. However, we see that resources have multiple instances and get freed on time. And hence, deadlock does not occur.
Like,
P4 uses R2 and free one instance of R2.
P3 then uses one instance of R2 and free R2.
P3 then uses one instance of R3 and free R3.
P1 uses one instance of R1 and free R1 one instance
P1 then uses R2 and free R2.
P2 uses R1 and free R1.
Hence, all the processes are complete and deadlock does not occur.
Answer:
High level language.
Explanation:
High level language can be defined as a programming language which is generally less complex than a machine (low level) language and easy to understand by the end users (programmers).
This ultimately implies that, a high level programming language is typically a user friendly language and as such simplifies coding or programming for beginners.
Some examples of high level programming language are Python, Java, C#, Ruby, Perl, Visual Basic, PHP, Cobol, C++, Fortran, Javascript, etc.
In this scenario, Huzaifa is a grade 5 student who is very enthusiastic to learn coding in computers. He asks his computer teacher to help him choose a language to code. Thus, the language level the teacher will recommend to Huzaifa is a high level language.
