Explanation:
IP Address: 215.200.110.50
The first process is to convert all octets to binary individually.
215 to binary
i.e. to divide by 2 as follows:
NOTE:
rem means (remainder)
215/2 = 107 rem 1
107/2 = 53 rem 1
53/2 = 26 rem 1
26/2 = 13 rem 0
13/2 = 6 rem1
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem1
Then count the remainders from down to up:
So, 215 of decimal is 11010111 in binary
Converting 200 to binary, we divide 200 by 2 until the quotient is 0
200/2 = 100 rem 0
100/2 = 50 rem 0
50/2 = 25 rem 0
25/2 = 12 rem is 1
12/2 = 6 rem 0
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 200 of the decimal is 11001000 in binary
Converting 110 to binary; we divide 110 by 2 until the quotient is 0
110/2 = 55 rem 0
55/2 = 27 rem 1
27/2 = 13 rem 1
13/2 = 6 rem 1
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 110 of the decimal is 1101110 in binary
In binary,110 = 01101110
We divide 50 by 2 until the quotient is 0
50/2 = 25 rem 0
25/2 = 12 rem 1
12/2 = 6 rem 0
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 50 of the decimal is 110010 in binary
To determine the network ID, we keep the first 25 bits of 11010111.11001000.01101110.00110010 and locked all remaining bits to 0.
Thus, network ID in binary is 11010111.11001000.01101110.00000000
Therefore;
11010111.11001000.01101110.00000000 as a decimal notation = 215.200.110.50
Thus, the four subnet IDs are:
11010111.11001000.01101110.00000000 ⇒ 215.200.110.0 0
11010111.11001000.01101110.01000000 ⇒ 215.200.110.64
11010111.11001000.01101110.10000000 ⇒ 215.200.110.128
11010111.11001000.01101110.11000000 ⇒ 215.200.128.19
How does the OS used and the specific applications on the system impact selection of a file management system?
Answer:
Explanation:
The functions of a file manager include the following.
The ability to format and copy disks
Listing of files in a storage channel.
A regular routine check of space used and unused space in the storage device.
The ability to organize, copy, move, delete, sort, or create shortcuts.
Storage and retrieval of data for the storage device. etc
In contrast, the system has some of the following functions.
Assigning queued document numbers for processing- Applications and Operating system dependent
Owner and process mapping to track various stages of processing - Operating system dependent
Report generation - Applications and Operating system dependent
Status - Operating system dependent
Create, modify, copy, delete, and other file operations - Operating system dependent
We can thereby conclude that file management system is dependent on OS and specific applications.

write a 2d array c program that can capture marks of 15 students and display the maximum mark, the sum and average
Answer:
#include <stdio.h>
int MaxMark(int* arr, int size) {
int maxMark = 0;
if (size > 0) {
maxMark = arr[0];
}
for (int i = 0; i < size; i++) {
if (arr[i] > maxMark) {
maxMark = arr[i];
}
}
return maxMark;
}
int SumMarks(int* arr, int size) {
int sum = 0;
for (int i = 0; i < size; i++) {
sum += arr[i];
}
return sum;
}
float AvgMark(int* arr, int size) {
int sum = SumMarks(arr, size);
return (float)sum / size;
}
int main()
{
int student0[] = { 7, 5, 6, 9 };
int student1[] = { 3, 7, 7 };
int student2[] = { 2, 8, 6, 1, 6 };
int* marks[] = { student0, student1, student2 };
int nrMarks[] = { 4, 3, 5 };
int nrStudents = sizeof(marks) / sizeof(marks[0]);
for (int student = 0; student < nrStudents; student++) {
printf("Student %d: max=%d, sum=%d, avg=%.1f\n",
student,
MaxMark(marks[student], nrMarks[student]),
SumMarks(marks[student], nrMarks[student]),
AvgMark(marks[student], nrMarks[student]));
}
return 0;
}
Explanation:
Here is an example using a jagged array. Extend it to 15 students yourself. One weak spot is counting the number of marks, you have to keep it in sync with the array size. This is always a problem in C and would better be solved with a more dynamic data structure.
If you need the marks to be float, you can change the types.

_________________ schedules the processor giving preference to the job with the shortest execution time.
Answer:
SJF
Explanation:
SJF is an acronym for the word, Shortest Job First. It is a scheduling algorithm that dies exactly what the question asked i.e, scheduling the processors by giving a much higher preference to jobs that posses the most little, or the shortest time of execution. It also brings down the usual waiting time for other processes that are for whatever reasons, yet to be executed.
Most C++ catastrophe vulnerabilities rely on uninitialized function pointers in a class.
a. True
b. False
Answer:
This is true
Explanation:
In an array-based implementation of a dictionary, if you represent the entries as an array of objects that encapsulate each search key and corresponding value, how many pointers will you use per array entry?
a. 3
b. 4
c. 2
d. 1
Answer:
The answer is "Option C".
Explanation:
Dictionary is a set of unsorted data values, that is used to save data like a map and which contains a key: value pair in comparison to many other types of data, which only carry a specific number as just an element.
If we use Dictionary as an array so, it uses a two-pointer variable, one for hold key, and the second is used to hold its value.

2. The last valid assignable host address of 172.22.4.129/26 is 172.22.4.190.
3. The first and last host address of 192.167.25.25/16 is 192.167.0.1 and 192.167.255.254.
4. The broadcast address of 10.75.96.0/20 is 10.75.111.255
Explanation:
Subnetting in networking is the process of managing the use of host addresses and subnet masks of a network IP address. For example, the IP address "172.22.49.252/17" is a class B address that receives an extra bit from the third octet which changes its subnet-mask from "255.255.0.0" to "255.255.128.0". with this, only 32766 IP addresses are used, with the network address of "172.22.0.0/17".

Should Manufacturers Include Extra Programs in Operating Systems for Computers and Mobile Devices?
Answer:
Well, it depends. Sometimes the extra programs can be useful or just plain fun, in which case the answer is yes. But extra programs can also sometimes be utterly useless and get in the way, in which case the answer is no.\
The development of software for computers benefits greatly from an operating system.
What is operating systems?Without an operating system, each program would have to contain both its own user interface (UI) and the complete code required to manage all low-level computer operations, such as disk storage, network connections, and other things.
This would greatly increase the size of any application and render software development difficult given the wide variety of underlying hardware available.
Instead, a lot of routine operations, such transmitting a network packet or showing text on a display or other conventional output device, can be delegated to system software, which acts as a bridge between applications and hardware.
Applications can interact with the system in a predictable and consistent manner thanks to the system software.
Therefore, The development of software for computers benefits greatly from an operating system.

Consider a processor with a 2 ns clock cycle, a miss penalty of 20 clock cycles, a miss rate of 0.05 misses per instruction, and a cache access time (hit time) of 1 clock cycle. Assume that the read and write miss penalties are the same.
a. Find the average memory access time (AMAT).
b. Suppose we can improve the miss rate to 0.03 misses per instruction by doubling the cache size. However, this causes the cache access time to increase to 1.2 cycles. Using the AMAT as a metric, determine if this is a good trade-off.
c. If the cache access time determines the processor’s clock cycle time, which is often the case, AMAT may not correctly indicate whether one cache organization is better than another. If the processor’s clock cycle time must be changed to match that of a cache, is this a good tradeoff?
Assume that the processors in part (a) and (b) are identical, except for the clock rate and the cache miss rate. Assume 1.5 references per instruction (for both I-cache and D-cache) and a CPI without cache misses of 2. The miss penalty is 20 cycles for both processors.
Answer:
a) 4 ns
b) 3.6 ns
Explanation:
Given that
Miss penalty = 20 * 2
Miss rate = 0.05
Clock cycle = 2 ns
Hit time = 1 * 2
The Average Memory Access Time or AMAT is found by using this formula
AMAT = Hit time + Miss rate × Miss penalty
Substituting directly for the values, we get
AMAT = 2 + [0.05 * (20 * 2 ns)]
AMAT = 2 + (0.05 * 40)
AMAT = 2 + 2
AMAT = 4 ns
b) given that
Miss rate = 0.03
Hit time = 1.2 * 2
Miss penalty remains the same = 40
AMAT = (1.2 * 2) ns + [0.03 * 40] ns
AMAT = 2.4 ns + 1.2 ns
AMAT = 3.6 ns
Considering that the AMAT is 3.6, we can say that it is a good trade-off.
c) CPU time = Clock cycle * IC * (CPIideal-cache + cache stall cycles per instruction)
CPU time
(a) = 2 ns * IC * (2 + 1.5 * 20 * 0.05) =
CPU time = 2 * IC * (2 + 1.5)
CPU time = 2 * IC * 3.5
CPU time = 7 * IC
(b)
CPU time = 2.4 ns * IC * (2 + 1.5 * 20 * 0.03)
CPU time = 2.4 * IC * (2 + 0.9)
CPU time = 2.4 * IC * 2.9
CPU time = 6.96 * IC
The CPU times we calculated in parts (a) and (b) are nearly the same. Thus, we can conclude that, doubling the cache size to improve the miss rate at the expense of stretching the clock cycle results in virtually no net gain.

Write a general-purpose program with loop and indexed addressing that adds 12h to 0th, 3rd , 7th , 11th ,15th ,19th , … elements of a DWORD array. For example, in array:
Answer:
def ishex(mylist):
hnum = 0x12
for index, item in enumerate(mylist):
if int(str(item), 16):
if index == 0:
print(hex(item + hnum))
elif item in mylist[3::4]:
print(hex(item + hnum))
else:
print(hex(item))
Dword = [0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1a, 0x1b, 0x1c, 0x1d, 0x1e, 0x1f]
ishex(Dword)
Explanation:
The python source code defines a function called "ishex" which takes a list as its parameter, loops through its index and value, checks if it is a hexadecimal number and adds 0x12 to every fourth index value of the list "Dword".
What is output?
C = 1
Sum = 0
while (c less than 10):
C = c + 3
sum = sum + c
print (sum)
Answer:
The output of code will be 10
Explanation:
We need to find output of following code:
C = 1
Sum = 0
while (c less than 10):
C = c + 3
sum = sum + c
print (sum)
Solution:
We will check the condition of while loop, if the condition is true, then the statements inside the loop will be executed. Since brackets are not available so, only one statement is linked with while loop.
First while loop will be executed c < 10 (1<10) the condition becomes true, and statement c=c+3 will be executed ( 4=1+3) and then loop condition will be checked (4<10) the condition becomes true, and statement c=c+3 will be executed ( 7=4+3) and then loop condition will be checked (7<10) the condition becomes true and statement c=c+3 will be executed ( 10=7+3) and then loop condition will be checked (10<10) the condition becomes false, so we will come outside loop body and execute: sum=sum+c (10=0+10) and print sum i. e 10
So, The output of code will be 10
