Which statements are true about a database?


A database allows only numeric entries.



You cannot upload image files to a database.



You can enter data based on the defined data type.



You cannot leave a field empty.



A primary key uniquely identifies a record.

Answers

Answer 1

Answer:

You can enter data based on the defined data type.

A primary key uniquely identifies a record.

Explanation:

In a database, you can only enter data that matches the data type you have specified for that field. Therefore, you can enter text in fields with the text data type; numbers in fields with the number data type; or images in fields with the BLOb data type. You can have fields where data entry is optional. A primary key eliminates the chance of duplicate entries of the same record in a table.

Why does a bus topology require a terminator? a) because otherwise it would be a ring network b) because otherwise the packets will bounce back and forth from end to end repeatedly c) because otherwise the signal will fade out d) because a terminator is where a bus network connects to the outside

Answers

Answer:

B)because otherwise the packets will bounce back and forth from end to end repeatedly

Explanation:

Bus topology can be regarded as a kind of topology for a Local Area Network, it is one that has it's nodes connected to a single cable(backbone) and any break in the so called backbone, there will be failure in the entire segment. However a Terminator is usually attached to the end-points of a bus network so that the signal is absorbed by the Terminator and as a result of this the signal will not reflect back down the line. If there is no Terminator there would be bouncing back and forth of packet in an endless loop.It should be noted that a bus topology require a terminator because otherwise the packets will bounce back and forth from end to end repeatedly

.

The answer is-

B.) because otherwise the packets will bounce back and forth from end to end repeatedly

Currently, this program will add 6 and 3 together, output the math problem and output the answer. Edit this code so that a random number is generated from 1 - 10 (inclusive) for the variables a and b. Also, instead of adding the two numbers together, the edited program should multiply them, and output the proper math problem and answer. Be sure to update every line of code to reflect the changes needed.
import random

a = 6
b = 3

answer = a + b

print (str(a) + " + " + str(b) + " = " + str(answer))

Answers

I've included my code in the picture below. Best of luck.

The modifications to be done program is an illustration of random numbers using Python.

The random numbers from 1 to 10, will be generated using the random module

The modified program where comments are used to explain the lines of the programs are:

#This imports the random module

import random

#This generates a random number

a = random.randint(1,10)

#This generates another random number

b = random.randint(1,10)

#This multiplies both numbers

answer = a * b

#This displays the result of the program

print (str(a) + " * " + str(b) + " = " + str(answer))

At the end of the program, the program will print the product of both random numbers.

Without net neutrality, which of these situations might occur? (Select all that apply.) a cable company might charge different bandwidth rates for large corporations and individual consumers an online newspaper might find its website slowing down because a telecomm company does not like its politics a big movie studio might find its upcoming film streamed illegally a service provider might choose not to provide service in poor areas

Answers

Answer:

a. a cable company might charge different bandwidth rates for large corporations and individual consumers

b. an online newspaper might find its website slowing down because a telecomm company does not like its politics

d. a service provider might choose not to provide service in poor areas

Explanation:

Net Neutrality is the idea that internet service providers are not to discriminate against users or treat them unequally due to their content, the information they wish to share, their website, the type of device they are using, etc. This principle also ensures that users are not charged differently based on the reasons listed above, among others.

Without this principle put in place, internet service providers can decide to slow down people's networks, charge differently, or entirely block a network because the users do not measure up to some of their standards or criteria.

Convert the following decimal numbers into equivalent binary numbers and then convert the binary answer back into equivalent decimal. Show all the steps of conversions.
• -8735

Answers

Answer:

[tex]-8375_{10} = -10001000011111_2[/tex]

[tex]-10001000011111_2 = -8735_{10[/tex]

Explanation:

Given

-8735

Required

Convert to binary and then back to decimal

To convert to binary, we divide by 2 and write down the remainder (ignore the negative sign, first)

8735 / 2 = 4367 R 1

4367 / 2 = 2183 R 1

2183 / 2 = 1091 R 1

1091 / 2 = 545 R 1

545 / 2 = 272 R 1

272 / 2 = 136 R 0

136 / 2 = 68 R 0

68 / 2 = 34 R 0

34 / 2 = 17 R 0

17 / 2 = 8 R 1

8 / 2 = 4 R 0

4 / 2 = 2 R 0

2 / 2 = 1 R 0

1 / 2 = 0 R 1

Write out the remainder from bottom to top

[tex]8735_{10} = 10001000011111_2[/tex]

Include the negative:

[tex]-8735_{10} = -10001000011111_2[/tex]

To convert to decimal, we simply multiply the individual digits with the base (in this case, it is base 2) raise to power of the index of that digit.

There are 14 digits in 10001000011111 and the rightmost digit is of index 0 and it increased to the left.

Ignore the negative, first; so, we have:

[tex]10001000011111_2 = 1 * 2^{13} + 0 * 2^{12} + 0 * 2^{11} + 0 * 2^{10} + 1 * 2^{9} + 0 * 2^{8} + 0 * 2^{7} + 0 * 2^{6} + 0 * 2^{5} + 1 * 2^{4} + 1 * 2^{3} + 1 * 2^{2} + 1* 2^{1} + 1 * 2^0[/tex]

[tex]10001000011111_2 = 1 * 8192 + 0 + 0 + 0 + 1 * 512 + 0 + 0 + 0 + 0 + 1 * 16 + 1 * 8 + 1 * 4 + 1* 2 + 1 * 1[/tex]

[tex]10001000011111_2 = 8192 + 512 + 16 + 8 + 4 + 2 + 1[/tex]

[tex]10001000011111_2 = 8735[/tex]

Include the negative sign

[tex]-10001000011111_2 = -8735_{10[/tex]
