Using python knowledge and writing code importing pandas, it is possible to create a function that corresponds to what you want.

<h3>Writting in python:</h3>

<em>import pandas as pd</em>

<em>if __name__ == "__main__":</em>

<em>    df=pd.read_csv('mtcars.csv')</em>

<em>    cylinders=int(input())</em>

<em>    print(df[df.cyl==cylinders].shape)</em>

MakcuM [25]

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment

Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :

EMI

RFI

Explanation:

  • EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
  • During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
  • EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
  • Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
  • The internal circuits of personal computers generate EM fields in the RF range.

The ACME Online Store offers different preferred customer discounts for customers who are "None", "Bronze", "Silver" and "Gold".
Nookie1986 [14]

Yes, the written program has the correct logic to assign the correct discount for each of the 4 valid values of customer_category

<h3>What is a Program?</h3>

This refers to the sequence of instructions that are keyed into a computer to execute user-specific commands.

Hence, we can see that based on the variable customer_category that has a string that is one of these 4 values:

0 for "None"

5 for "Bronze"

10 for "Silver"

20 for "Gold"

The program uses the correct syntax as it gives the correct discount based on the assigned values of the variable customer_category as executed with the syntax above.

A 1024-bit message is sent that contains 992 data bits and 32 CRC bits. CRC is computed using the IEEE 802 standardized, 32-degr
Studentka2010 [4]

Answer:

a) Yes

b) Yes

c) Yes

d) No

e) Yes

f) No

Explanation:

a) All single-bit errors  are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.

b) All double-bit errors for any reasonably long message  are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.

c) 5 isolated bit errors  are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.

It produces nearly 100 % of error detection.

d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.

e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.

f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.

Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.
