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.

Explain the three schemes via which the binding of instructions and data to memory addresses can be done. In each scheme, how the logical address can be converted to physical address?
Answer:
Compile time
Load time
Execution time
Explanation:
The binding of instructions can be done in three steps, which are:
Compile time
Load time
Execution time
• Compile time In compile time, absolute code is usually generated when the compile time where the process resides in the memory is known
• Load time - in contrary to compile time, if it is not known at compile time where the process will reside in memory, then the compiler has to generate a relocatable code. In this scenario, the final binding is usually delayed until load time.
• Execution time - if the process is able to be moved during its execution from a particular memory segment to another segment, then binding is delayed until run time.

Answer:
true
Explanation:
Corey set up his presentation for delivery to his team.
Answer:
If Corey wants to control the pacing of his presentation, he should adjust his playback settings. In the playback settings, he should select the default setting under "type;" this will allow him to change slides anytime. He should also click the check box under "options" that says "Change slides manually" so he can simply click on the slide whenever he is ready to move on to another slide.
Explanation:
If you don't like that answer, here's another one:
Corey knew he would need a lot of time to explain each point and that his team members would have lots of comments and questions. The best way that Corey should set up his slide show would be to make sure that he has an outline. Also, there should only be one thought per slide (never mix it). It has to be taken into account that he should have fewer words and more images/graphs.
Which button in the Sort & Filter gallery of the Data tab would alphabetize from A to Z quickly?
Answer:
the answer is B (AZ down arrow)
Explanation:
How many RTTs does it take until the sender's congestion window reaches 2M bytes? Recall that the congestion window is initialized to the size of a single segment, and assume that the slow-start threshold is initialized to a value higher than the receiver’s advertised window.
The question is incomplete, Below is the complete question.
Suppose that you are using an extended version of TCP that allows window sizes much larger than 64K bytes.1 Suppose you are using it over a 1Gbps link with a round-trip time (RTT) of 200ms to transfer 16M-byte file, and the TCP receiver's advertised window is 2M bytes. If TCP sends 1K-byte segments, and assuming no congestion and no lost segments:
(a) How many RTTs does it take until the sender's congestion window reaches 2M bytes? Recall that the congestion window is initialized to the size of a single segment, and assume that the slow-start threshold is initialized to a value higher than the receiver’s advertised window.
(b) How many RTTs does it take to send the file?
(c) If the time to send the file is given by the number of required RTTs times the RTT value, what is the effective throughput for the transfer? What percentage of the link capacity is utilized?
Answer/Explanation:
(A)
When;
RTT0 = 1KB
RTT2 = 4KB
RTT1 = 2 KB
RTT3 = 8KB
RTTn = 2nKB.......
We need n = 11 to have 2 MB = 211.
With that, the window size will become 2MB after 11 RTTs.
(B)
By the 11th RTT 2MB have been transmitted and the window is 2MB, then, by the end of the 12th RTT,2MB have been transmitted and the window is now 2MB. Similarly during the next 3 RTTs, another 2MB will be transmitted, 4MB and another 2MB, thus 15 RTTs is needed to transmit the entire file.
c) Effective throughput for the transfer is the file size over the needed time i.e,
= 8 * 16Mb / (15 * 200 * 10-3)
which is;
= 144 / 3000 * 10-3
Then;
= 144 * 103 / 3000
And;
= 48 Mbps(Megabit per second)
Bandwidth Utilization = effective throughput / Available link speed
= 48 / 1024
= 0.0468
= 4.68 %
MB = MegaBytes
while
Mb = Megabits

while (c 10):
C = c + 5
print (c)
Answer:
The answer is:
5
10
Explanation:
In the while loop, we specify, if C is not equal to 10, C += 5 and print(c). When python reads the loop, python will check to see if C is equal to 10 and if not it will add 5 until C is more than or equal to 10. In addition, python will print(c) to the console until it hits 10. Once C is less than or equal to 10 the loop will stop. In this scenario, since we print c in the loop, the codes output will be the following:
5
10

The replacement policy that can be implemented in practice and performs the best among the replacement policies that can be actually coded is:
Answer:
The answer is "Least recently used policy".
Explanation:
It is the page replacement policy, which uses a less frequent substitute. It adds a registry from each frame that includes the last time the program, that views within the frame, and use a "logical clock" for each of the data references, that made to change by a tick.
This replacement strategy is often used to substitute its least currently utilized cache line or page, and it is realistic and best implemented among the substitution policies.
Suppose datagrams are limited to 1,500 bytes (including header) between source Host Aand destination Host B. Assuming a 20-byte IPheader, how many datagrams would be required to send an MP3 consisting of 5 million bytes? Explain how you computed your answer.
Answer:
3424 datagrams would be required
Explanation:
Mp3 file size = 5 million bytes
assuming the data is carried in TCP segments with each TCP segment have 20 bytes of header
Therefore each datagram can carry at least : ( 1500 - 40 ) = 1460 bytes
Therefore the number of datagrams required = [tex][\frac{5*10^6}{1460} ][/tex] = 3424
The MP3 file to be transmitted does have a size of 5 million bytes or [tex]5 \times 10^6\ \ bytes[/tex]. Suppose that information is moved via TCP segments with a TCP header size of 20 bytes.
Each IP header is 20 bytes long, and the TCP header is also 20 bytes long. Therefore, we use 40 bytes out of a total of 1500 bytes for IP and TCP headers. Then, in each datagram, we can send [tex]1500-40 = 1460[/tex] bytes of MP3 files. So, overall number of data packets necessary:[tex]= \frac{\text{Total MP3 Size}}{\text{ MP3 Size}}[/tex]
calculating the each datagram that is capable of transporting:[tex]\to \frac{5000000}{ 1460} \\\\ \to 3424.65753425 \\\\\to 3425 \ \ Datagrams.[/tex]
Except for the last one, all datagrams would be 1500 bytes in size. Your final datagram will be 1000 bytes long, i.e,[tex]\to 1460 \times 0.65753425 \\\\ \to 960 + 40 \ \text{(Bytes of Header)} \\\\ \to 1000 \ Bytes\\[/tex]

The array elements are always stored in__________memory locations. Write the word consecutive or random in the blank appropriately.
Answer:
contiguous.
Explanation:
An array can be defined as a set of memory locations (data structure) that comprises of a group of elements with each memory location sharing the same name. Therefore, the elements contained in array are all of the same data type e.g strings or integers.
Basically, in computer programming, arrays are typically used by software developers to organize data, in order to search or sort them.
Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements.
Binary search applies the principles of divide and conquer.
In order to do a binary search on an array, the array must first be sorted in an ascending order.
The array elements are always stored in contiguous memory locations.
It should be be noted that the array elements are always stored in contiguous memory locations.
According to the question, we are to discuss the array elements and how they are been always stored .
As a result if this we can see that array elements are always stored in contiguous memory locations so as to enable the retrieval of the information.
Therefore, array elements are always stored in contiguous memory locations.
