Transmission delay and propagation delay

a.How many milliseconds does it take for a packet of length 1,000 bytes to be delivered from the sending host to the receiving host over a link of distance 1,200 km, propagation speed 2.4×108 m/s, and transmission rate 10Mbps (consider both transmission delay and propagation delay)?

b. More generally, how long does it take a packet of length L to be delivered from the sending host to the receiving host over a link of distance d, propagating speed s, and transmission rate R bps?

c. How many milliseconds does it take for the first bit of the packet to arrive at the receiving host (start to count the time when the sending host starts to transmit the first bit of the packet)?

d. How many milliseconds does it take for the last bit of the packet to be put on the link (start to count the time when the sending host starts to transmit the first bit of the packet)?

Suppose there are exactly two packet switches (switch#1 and switch#2) between a sending host and a receiving host. The transmission rate between the sending host and switch#1 is R1. The transmissions rate between switch#1 and switch#2 and between switch#2 and the receiving host are R2 and R3, respectively. Assuming that the switches use store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.)

underlying theoretical components of a perspective on learning and b) implications for the design of science learning environments, including curriculum and instruction.

How students learn science has focused on a great deal of educational theory, research, and ‘best practices’ of instruction. Draw from this body of work to define, describe, and articulate a theory-driven and research-based position on the nature of science teaching and learning. Your response should address a) underlying theoretical components of a perspective on learning and b) implications for the design of science learning environments, including curriculum and instruction.

Igbo Nationalism,self determination and the crisis of secessionist movement in Nigeria.

Igbo Nationalism,self determination and the crisis of secessionist movement in Nigeria. For this assignment, you will write a 3-4 page proposal that outlines your goals for your project, why your topic matters (and for whom), and how you plan to design your project. This is a moment for you to pause and reflect on exactly what you are planning so that you can identify areas that may need more work or things you want to explore from a different perspective. Your proposal should: 1) Formulate your topic as an explanatory research question/s 2-) Discuss the importance of the chosen topic 3-) Justify case selection and time period under study 4-) Introduce a methodology and brief overview of the sources you will work

Write a brief 1,000 word report explaining the structure of the questionnaire and the steps your took in designing it to address the management problem.

The Department of Consumer affair decided to commission research to get a better understanding of the factors such as socio demographics, cultural values, shopping motivation and memorable experience of Australian domestic and international travellers that influence their future behavioural intention in the context of conspicuous consumption.
