Suppose users share a 1 Mbps link. Also suppose each user

requires100

kbps when transmitting, but each user transmits only 10 percent

ofthe time.

(See the discussion Packet Switching Versus Circuit Switching

inSection 1.3).

A. When circuit switching is used, how many users can

besupported?

B. For the remainder of this problem, suppose packetswitching is

used.

Find the probability that a given user is transmitting.

C. (Suppose that there are 50 users. Find the probability that

atany given

time exactly n users are transmitting simultaneously (Hint: use

thebinomial

distribution).

D. Find the probability that there are 11 or more

userstransmitting

simultaneously. (Hint: use the central limit theorem.)

E. Solve D for 20 or more users.

Answers

Answer 1

Answer:

The answer is below

Explanation:

A) The total bandwidth = 1 Mbps = 1000 Kbps

The requirement for each user = 100 Kbps

Total number of users = Total bandwidth /  requirement for each user

Total number of users = 1000 Kbps / 100 Kbps = 10 users

B) Since each user transmits only 10 percent  of the time, probability that a given user is transmitting is:

Probability = 0.1

C) Binomial distribution formula is given by:

[tex]P(x)= C(n,x)p^x(1-p)^{n-x}\\\\n = number\ of \ trials,x=number\ of\ success, p=probability\ of\ success \ for\ one\ trial[/tex]Hence:

Probability=[tex](50\ choose\ n)p^n(1-p)^{50-n}[/tex]

[tex]P=C(50,n)p^n(1-p)^{50-n}[/tex]

D) The probability that there are 11 or more is:

[tex]Probability=1-\Sigma\limits^{20}_0 {(50\ choose\ n)p^n(1-p)^{50-n}}[/tex]

As we learned in this lesson, a byte is about the same amount of memory as a character, such as the letter 't'. There are approximately 7 million characters in all of the Harry Potter novels combined. How many bytes of memory would all of the Harry Potter novels take up? How many copies of the Harry Potter novels would fit on a 7 Gigabyte flash drive. (Remember 1 Gigabyte is 1 billion bytes.)​

Answers

Answer:

Give an example of a special purpose computer that you are familiar with and briefly describe its hardware and its software.

One example of a special purpose computer is a microwave because the programs on a microwave (like the "Popcorn" program) can't be changed. The hardware of a microwave include its buttons, the door, the light bulb, the transformer, the waveguide, the magnetron, and the control circuit. The software of a microwave is all of the programs that make the microwave run. These include the "Popcorn" program that is supposed to perfectly make your popcorn, the "Sensor" program that senses for a certain type of food/drink and adjusts the temperature accordingly, or a "Defrost" program which can be used to defrost meat.

   2. Explain in your own words the difference between running your app by "Connecting to the Companion" and running your app by "Packaging" it.

When running the app by "Connecting to the Companion", the MIT companion app transfers the software (blocks) to the phone and then interprets them for the Android operating system. The Android OS takes the software and interprets it for the phone's processor so the app can run. Because of the way "Connecting to the Companion" works, the code can be re-interpreted every time a change is made. This process is known as interpretation because the code is constantly being re-interpreted.

When running the app by "Packaging" it, a program changes the software (blocks) on the computer into binary code and then packages it in an .apk file. Using a barcode scanner or another piece of software, the .apk file can be loaded onto the phone so the Android OS can interpret the code for the phone's processor. This process is called compilation since all of the source code is changed into binary.

Which of the following is a trademark automatically received by an organization when a symbol is being consistently used in the normal course of business?

Answers

Complete Question:

Which of the following is a trademark automatically received by an organization when a symbol is being consistently used in the normal course of business?

Group of answer choices

A. Open source trademark.

B. Common law trademark.

C. Registered trademark.

D. Open source trademark.

Answer:

B. Common law trademark.

Explanation:

A common law trademark can be defined as a protection or enforceable mark for a product name, logo, symbol or brand name used to distinguish goods and services prior to its registration with the state or federal government. Common law trademark is a trademark which is automatically received by an organization when a symbol is being consistently used in the normal course of business.

This ultimately implies that, common law trademarks are not governed by any statute and as such are only limited to the geographical location where they are used.

For instance, if a tomato paste is being sold to consumers with the product name "Ginoo" in Florida, the company's trademark applies to Florida only. Thus, another company can use the product name without any trademark infringement in other states of the country such as New York, Washington DC, California etc. except in Florida due to a common law trademark.

Answers

Answer:

12 20

Explanation:

alright so, lets keep track of our variables

j+= 2 is j = j+2

so j is 12, and k += j is k = k + j so k is then 20.

j=12, k=20

It would print

12 20

because of the "space" on your second print statement, and the third would create a new line AFTER printing itself first.
