Suppose two hosts, a and b are separated by 100,000 kilometers and are connected by a direct link of r = 2 mbps. suppose the propagation speed over the link is 2*108 meters/sec. consider sending a file of 800,000 bits from host a to host b.
a. [20 pts] suppose the file is sent continuously as one big message. how long does it take to send the file, assuming it is sent continuously?
b. [20 pts] suppose now the file is broken up into 40 packets with each packet containing 20,000 bits. suppose that each packet is acknowledged by the receiver and the transmission time of an acknowledgement packet is negligible. finally, assume that the sender cannot send a packet until the preceding one is acknowledged. how long does it take to send the file?

we need a link or picture : )

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
