Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2

= 2 Mbps, and R3 = 1 Mbps. a. Assuming no other traffic in the network, what is the throughput for the file transfer? b. Suppose the file is 4 million bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B? c. Repeat (a) and (b), but now with R2 reduced to 100 kbps

Answer & Explanation:

a)

Throughput means the speed of the slowest link which is bottleneck for the network.

In the above case R1 = 500kbps is the throughput for file transfer.

b) Give file size = 4 million bytes =4 * 1,000,000 * 8 bits = 32,000,000 bits =

Time taken to transfer the file = filesize/throughput = 32,000,000/500,000 = 64 seconds

When R2 reduced to 100kbps

a)  

In this case R2 = 100kbps is the throughput for file transfer.

b) Give file size = 4 million bytes =4 * 1,000,000 * 8 bits = 32,000,000 bits =

Time taken to transfer the file = filesize/throughput = 32,000,000/100,000 = 320 seconds

But even after it many of the users have difficulty in using this tools when it comes to the powerful cases.

There are some steps through that one can start to use this tool for their productivity.

To built the blocks

To organize the notions.

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give
gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load    A                   # variable A will be loaded

Add     B                  # B will be added to A

Store   Temp1         # A + B will be stored in Temp1

Load    C                  # C will be loaded in memory

Add     D                 # D will be added to C

Store   Temp2         # C + D will ge stored in Temp2

Load    Temp1         # Temp1 will be loaded in the memory

Subt     Temp2         # Temp2(A + B) get subtracted from Temp1(A - B)

Store    Sum             # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

  • R1
  • R2
  • R3
  • R4

The program is as follows:

Load   R1 , A     #A  will be loaded into R1

Load   R2 , B    # B will be loaded into R2

Add     R1 , R2    # R2 gets added to R1 and the result is stored in R1 (A + B)

Load   R3 , C      # C loaded into R3

Load   R4 , D     # D loaded into R4

Add    R3 , R4   # Value in R4 gets added into R3 and R3 becomes (C + D)

                          #no memory accesses required for this operation

Subt   R1 , R4     #R4 (C + D) gets subtracted from R1 (A + B)

                         #no memory accesses required for this operation

Store  Sum        # The recent value will be stored into Sum

Here memory is accessed 5 times in total.
