Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
Incomplete question. The Options read;
A. The year purchased
B. Brian's classmates
C. The amount of memory
D. The type of operating system
Answer:
<u>B. Brian's classmates</u>
Explanation:
<em>Remember,</em> the question is concerned about <em>"the individuals"</em> in the data set, <u>so the year they purchased their computer, neither is the amount of memory of the computer and the type of operating system can be classified as individuals in the data set.</u>
Hence, we can correctly say, only Brian's classmates are the individuals in this data set.
Answer:
O DTP programs are basically layout programs.
Explanation:
Desktop publishers are vector-based graphics software, and a perfect example of one such software is Microsoft Publisher. You can consider Adobe Illustrator, and Corel Draw as well, but they are huge software meant for many more things, and hence let's include only Microsoft publisher. And a long list follows as well. And they are in general a layout program used to prepare cards, advertisements, infographics, etc, and in fact the layout for them. And hence its more appropriate to say that it is basically a layout program that uses vector graphics to accomplish its goal. Various formats supported are like SVG, EPS, PDF,AI etc. And these are vector graphics based formats. The other type is Raster, and that includes Photoshop etc, with formats iike jpeg, gif etc, and which are pixel based.
Answer:
A binary system is a system that functions on zeros and ones (0's and 1's).
A decimal system is an Arabic numeric system that has 10 as its base and uses a dot which is also called a decimal point to show fractions.
Differences
- A decimal uses ten different digits which is 0-9 while a binary system uses just two digits 0 and 1
- Decimal system was historically a Hindu-Arabic system while the binary system is just an Arabic system
Similarities
- They are capable of performing arithmetic operations
- They both can be represented in decimal form
