This elementary problem begins to explore propagation delay and transmis- sion delay, two central concepts in data networking. Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B
a. Express the propagation delay, dprops in terms of m and s
b. Determine the transmission time of the packet, drans, in terms of L and R.
c. Ignoring processing and queuing delays, obtain an expression for the end-
d. Suppose Host A begins to transmit the packet at time t = 0. At time t = dtrans'
e. Suppose drop is greater than dran . At time t = d, ans, where is the first bit of
f. Suppose dprop is less than dtrans. At time t = dtrans, where is the first bit of
g. Suppose s = 2.5-108, L = 120 bits, and R = 56 kbps. Find the distance m so that dprop equals drans
Answer:
A. dprops = m /s seconds.
B. drans = L / R seconds.
C. delay(end −to−end) = (m /s + L / R) seconds.
D. The bit has just been sent to Host B or just left Host A.
E. The first bit is in the link and has not reached Host B.
F. The first bit has reached Host B.
G. m = 535.714 km.
Explanation:
The transmission time or delay of packets in a network medium is the packet size L, divided by the bit rate R (in seconds). The propagation time or delay is the ratio of the distance or length of the transmission cable, m, and the propagation speed of the cable, S (in seconds).
The end-to-end delay or the Packet delivery time is the total delay in transmission, which is the sum of the propagation delay and the transmission delay.
To get the distance where the propagation delay is equal to the transmission delay;
distance (m) = L /R
= (120/56 ×10^3) 2.5 ×10^8 = 535.714 km

Suppose that one of the following control signals in the single-cycle MIPS processor has a stuck-at-0 fault, meaning that the signal is always O, regardless of its intended value. What instructions would malfunction? Why? (a) RegWrite (b) ALUOp1 (c) MemWrite Repeat for all three signals (a) to (c) above, assuming that the signal has a stuck-at-1 fault.
Answer:
Explanation:
RegWrite:
• All R-type instructions, lw and addi:
• The result of the operation/load/addition would not be written back to the destination register
• ALUOP
• The following R-type instructions: add, sub, and, or, slt
• With ALUOp stuck at 0, the ALU decoder would interpret all those instructions as either add or subtract operations. The ALUOp gets decoded to add or subtract depending on ALUOp[0].
• MemWrite:
• Only sw is affected.
• The memory write won’t take place.

Write a function that will sum all of the numbers in a list, ignoring the non-numbers. The function should takes one parameter: a list of values (value_list) of various types. The recommended approach for this:
a. create a variable to hold the current sum and initialize it to zero.
b. use a for loop to process each element of the list.
c. test each element to see if it is an integer or a float, and, if so, add its value to the current sum.
d. return the sum at the end.
In python 3.8:
def func(value_list):
lst = [x for x in value_list if type(x) == int or type(x) == float]
return sum(lst)
print(func(["h", "w", 32, 342.23, 'j']))
This is one solution using list comprehensions. I prefer this route because the code is concise.
def func(value_list):
total = 0
for x in value_list:
if type(x) == int or type(x) == float:
total += x
return total
print(func(["h", "w", 32, 342.23, 'j']))
This is the way as described in your problem.

Write a function that converts a string into an int. Assume the int is between 10 and 99. Do not use the atoi() or the stoi() function.
Answer:
Written in C++
#include <iostream>
#include <sstream>
using namespace std;
int main() {
string num;
cout<<"Enter a number: ";
cin>>num;
stringstream sstream(num);
int convertnum = 0;
sstream >> convertnum;
cout << "Output: " << convertnum;
}
Explanation:
Without using atoi() or stoi(), we can make use of a string stream and this is explained as follows:
This line declares a string variable num
string num;
This line prompts user for input
cout<<"Enter a number: ";
This line gets user input
cin>>num;
This line declares a string stream variable, sstream
stringstream sstream(num);
This line declares and initializes the output variable, convertnum to 0
int convertnum = 0;
The stream is passed into the output variable, convertnum
sstream >> convertnum;
This line displays the output
cout << "Output: " << convertnum;
Note that: if user enters a non integer character such as (alphabet, etc), only the integer part will be convert.
For instance,
40a will be outputted as 40

Martin is playing the role of a(n)
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
The question is about to identify the role of Martin, who converts script into visual form by creating a storyboard.
The correct answer to this question is:
Martin is playing the role of Production Design and he is working at the position of the production designer.
Before shooting a film, the production designer is the first artist who converts script into a visual form such as creating storyboards. And, that storyboard serves as the first film draft.
A storyboard is a series of sketches, paintings, etc arranged on a panel to show the visual progress of the story from one scene to the next. These storyboards are used from start to finish of the film. Because these storyboards or sketches serve as the visual guide for the director of the film throughout the production.

The single-cycle datapath conceptually described in this section must have separate instruction and data memories, because:________. a. the formats of data and instructions are diff erent in MIPS, and hence different memories are needed. b. having separate memories is less expensive. c. the processor operates in one cycle and cannot use a single-ported memory for two different accesses within that cycled. the formats of data and instructions are different in MIPS, and hence different R-type instructions are needed .
Answer:
C. The processor operates in one cycle and cannot use a single-ported memory for two different accesses within that cycle
Explanation:
Processors require instructions and data which are retrieved from data memories for processing, but it cannot access two or receive two both processes as only a port is used for accessing data and another for receiving instructions. In fact, a single-cycle or single-clock processor cannot use a resource more than once.

Please make me BrainliestWhat is the capacity of a disk with two platters, 10,000 cylinders, an average of 400 sectors per track, and 512 bytes per sector?
What is the use of cache memory? Explain the concepts of cache hit and cache miss.
Answer:
The capacity of the disk is "40 GB".
Explanation:
Given value:
[tex]\to \text{cylinder}= 10,000\\\\\to \frac{sector}{track} = 400\\\\\to \frac{bytes}{sector} = 512\\[/tex]
[tex]\text{Calculating the size of track} = \frac{bytes}{sector} \times \frac{sector}{track}[/tex]
[tex]= 512 \times 400 \\\\ = 204,800 \ \ Or \ \ 200 \ K[/tex]
[tex]\text{Calculating the size of surface} = \frac{byte}{track} \times \ cylinder[/tex]
[tex]= 2000 \ K \times 10,000 \\\\ = 20, 000,000 \ K[/tex]
[tex]\text{Calculating the capacity of a disk} = \frac{byte}{surface} \times \frac{surface}{disk}[/tex]
[tex]= 20, 000,000 \ K \times 2 \\\\ = 40, 000,000 \ K \\\\= 40 \ GB[/tex]
Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.
Hit Cache: when the Processor relates to representing database data, Cache Hit results. Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.It doesn't have to retrieve the Main Memory through secondary storage.You are troubleshooting an issue where a PC can reach some hosts on the Internet (using either DNS name or IP address), while several other hosts on the Internet are not reachable.
