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".

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
The cameras optical viewfinder is like a _ in which to compose your image
Answer:
Periscope
Explanation:
Optical viewfinders use a system of mirrors and prisms like a periscope. These mirrors bounce the image up to the viewfinder and can then be viewed by the eye.
The camera's optical viewfinder is like a periscope in which to compose your image.
What is a periscope?You can see around walls, corners, and other obstructions using a periscope. Periscopes are installed on submarines so that the occupants can see what is happening above the water. A good illustration of the law of reflection in action is a periscope.
Similar to a periscope, optical viewfinders work with a system of mirrors and prisms. These mirrors allow the image to be reflected up to the viewfinder, where it may be seen with the eye.
However, Periscope had already ceased allowing new users to sign up by that point. Six years after it was first made available to the public, Periscope was finally discontinued. Users can still access their old broadcasts by visiting the Periscope website and logging onto their accounts.
Therefore, to compose your shot, use the optical viewfinder of the camera, which functions like a periscope.

What is one major structural difference between a decision structure (such as a decoder) and a storage structure (such as an RS latch)?A. The storage structure requires a different class of gates.B. The storage structure requires a clock input.C. The storage structure uses feedback. D. The storage structure has no propagation delay.
Answer:
B. The storage structure requires a clock input.
Explanation:
Logic circuits are circuits in electronics that give output based on the logic gate principle and its inputs. It can be a sequential logic circuit or a combinational logic circuit.
Decoders RS latches are combinational logic circuits because they both comprise of a combination of several sequential circuits to make their systems. The difference between decoders and RS latches is that the RS is a storage structure which is made up of flip-flops which require a clock input
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.
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.

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

Explanation:

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.

Assume we want to sort integers into ascending order. To sort a small array that contains 42, 17, selection sort will perform one swap, or three assignments. How many assignments will it perform to sort an array that contains these 10 elements: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0?
a) 15
b) 18
c) 24
d) 27
e) 63
Answer:
a) 15
Explanation:
Since we are given a list that contains 10 elements [tex][ 9, 8, 7, 6, 5, 4, 3, 2, 1, 0][/tex]
To start with the first iteration:
We substitute element 9 with the least number in the list. In the list 0 is the least number, so by swapping it with 9 we have the list as:
[tex][ 0, 8, 7, 6, 5, 4, 3, 2, 1, 9][/tex]
For the second iteration:
we substitute element 8 with the minimum number in the list, Now the minimum number is 1, so by swapping it with 8 we have the list as:
[tex][ 0, 1, 7, 6, 5, 4, 3, 2, 8, 9][/tex]
For the third iteration:
we substitute element 7 with the minimum number in the list, Now the minimum number is 2, so by swapping it with 7 we have the list as:
[tex][ 0, 1, 2, 6, 5, 4, 3, 7, 8, 9][/tex]
For the fourth iteration:
we substitute element 6 with the minimum number in the list, Now the minimum number is 3, so by swapping it with 6 we have the list as:
[tex][ 0, 1, 2, 3, 5, 4, 6, 7, 8, 9][/tex]
For the fifth iteration:
we substitute element 5 with the minimum number in the list, Now the minimum number is 4, so by swapping it with 5 we have the list as:
[tex][ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9][/tex]
At this point, the array is completely sorted and there is no more room for swapping
Thus, the number of swaps required = 5
The no. of assignment required = 3 × 5
The no. of assignment required = 15
The number of assignments to sort the array of 10 elements is 15
How to determine the number of assignments?A swap operation involves 2 elements, and 3 assignments.
So, the number of assignments is calculated as:
n = Elements/2 * 3
There are 10 elements in the array.
So, we have:
n = 10/2 * 3
Evaluate the product
n = 15
Hence, the number of assignments to sort the array is 15

What is the first phone ever made?
Answer:
the Telephone
Explanation:
Before the invention of electromagnetic telephones, mechanical acoustic devices existed for transmitting speech and music over a greater distance greater than that of normal direct speech. The earliest mechanical telephones were based on sound transmission through pipes or other physical media.The acoustic tin can telephone, or "lovers' phone", has been known for centuries. It connects two diaphragms with a taut string or wire, which transmits sound by mechanical vibrations from one to the other along the wire (and not by a modulated electric current). The classic example is the children's toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with tautly held string.Some of the earliest known experiments were conducted by the British physicist and polymath Robert Hooke from 1664 to 1685. An acoustic string phone made in 1667 is attributed to him.For a few years in the late 1800s, acoustic telephones were marketed commercially as a competitor to the electrical telephone. When the Bell telephone patents expired and many new telephone manufacturers began competing, acoustic telephone makers quickly went out of business. Their maximum range was very limited. An example of one such company was the Pulsion Telephone Supply Company created by Lemuel Mellett in Massachusetts, which designed its version in 1888 and deployed it on railroad right-of-ways.Additionally, speaking tubes have long been common, especially within buildings and aboard ships, and they are still in use today. The telephone emerged from the making and successive improvements of the electrical telegraph. In 1804, Spanish polymath and scientist Francisco Salva Campillo constructed an electrochemical telegraph.The first working telegraph was built by the English inventor Francis Ronalds in 1816 and used static electricity. An electromagnetic telegraph was created by Baron Schilling in 1832. Carl Friedrich Gauss and Wilhelm Weber built another electromagnetic telegraph in 1833 in Göttingen.At the University of Gottingen, the two have been working together in the field of magnetism. They built the first telegraph to connect the observatory and the Institute of physics, which was able to send eight words per minute.
