List at least three things people are doing to design transportation systems that are better for the environment.

Daphne used to work in the city where she would take public transportation to work. However, she just took a new job in the subu

mr Goodwill [35]

Answer:

A need

Explanation:

Daphne has no choice but to get a car and a house immediately, she relocates. Anything that is a choice and gives you the desire to acquire it, but cannot, due to one reason or the other, is a want. A need, on the hand, is something that Daphne should have to survive. She will need a car and a house to stay alive and will obviously not do anything without them. A home and a car are physical needs that can be touched or measured while aspects like happiness and good health are subjective needs that we need as humans to survive.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a

Margaret [11]

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 = 1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec

A ________ record is a resource record that allows other servers to deliver Internet mail using SMTP.

Novay_Z [31]

The resource record that allows other servers to deliver Internet mail using SMTP is called; Mail Exchanger (MX)

<h3>Use of Mail Exchanger </h3>

The correct answer to the blank part of the question is "Mail Exchanger(MX)". This is because a mail exchanger record is simply an MX record that identifies the mail server that has the responsibility of accepting email messages on behalf of a domain name.

Now this Mail Exchanger also operates by allowing other servers to deliver Internet mail with the aid of SMTP(Simple mail transfer protocol)

Which of these devices takes the internet and sends it through the air to your devices?

maksim [4K]

Answer:

wired router

Explanation:

A wired router is used for the internet access. it collects the internet signals and distributes it in its vicinity. The devices we use catch those signals and help us send data from one device to another.

There are forms of internet as well which provide the same facility depending upon the kind of strength of signals they provide.

I hope the answer is helpful.

Thanks for asking.
