what's your choices for this question
Answer:
A. Xcode libraries
Explanation:
We have to find a requirement for developing game applications on devices running Apple’s iOS operating system. For that, I will evaluate each answer.
A. Xcode libraries
Xcode can be generally defined as a development kit or integrated development environment to facilitate the Apple software development. Apple use iOS operating system for its devices. To develop anything compatible with iOS, you generally have to code it using Xcode. Obviously, each development kit includes libraries for project to be built. Therefore, this option is correct.
B. Android Development Kit
Just like Xcode, Android Development Kit is used to build the software for android. It is pretty much comprehensible from its name. So, this option is false.
C. ARM technology and D. advanced microprocessors
These both options are related to hardware and available on both the devices. It is used for overall processing but these options are not that relevant to iOS operating system. Therefore, these options are false too.
So, Correct option is Xcode libraries.
Answer:
The answer to this question is the option "B".
Explanation:
In this question, the answer is option B which is 1,000 because the kernel is a central part of an operating system. kernel manages the computer and the hardware operations. most especially memory and CPU time. It also sheared a memory variable is allocated to thread blocks. That's why the answer to this question is 1,000.
Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>
Answer:
the CPU utilization decreases as the degree of multiprogramming is increased.
Explanation:
The fundamental concept is that allocating a process with too few frames causes too many and frequent page faults. This implies that the CPU does not perform any useful work and thus its utilization would decrease drastically. In this case, the long-term scheduler, in a bid to improve the utilization of the CPU, would load more processes into the memory so as to increase the extent of multiprogramming. As a result, there would be more decrease in the utilization of the CPU, leading to a chained reaction of higher page faults, which is then followed by a corresponding increase in the multiprogramming degree, usually known as thrashing.
