Page tables store information about page locations, allocated page frames, and secondary storage space.
What is a page table?In computing, a page table is a data structure utilized by a virtual memory system in a computer operating system to keep track of the virtual-to-physical address translations. It represents the page frame allocation for the operating system's main memory.
Virtual memory is a memory management method that allows an operating system to expand its effective memory size by moving data from RAM to disk storage. Virtual memory addresses are used by the system's memory manager, and the page table is used to translate virtual memory addresses to physical memory addresses.

Which one of the following data protection techniques is reversible when conducted properly?
A. Tokenization
B. Masking
C. Hashing
D. Shredding
The data protection technique that is reversible when conducted properly is Tokenization. Tokenization replaces sensitive data with a random string of characters called a token.
Tokens are generated by the tokenization system and are unique to the data element that they are replacing. The tokens generated by the tokenization system can be reversed back to the original data, given the right key/tokenization database. A tokenization system stores a map between the original sensitive data and the generated token. If the original data is needed, the map can be used to look up the original data element using the token that was created at the time of tokenization and recover the original value. As a result, tokenization is a reversible process when executed correctly. Masking and hashing, on the other hand, are irreversible processes. They permanently alter the original data and, once masked or hashed, the original data cannot be recovered. The following are more than 100 words on how Tokenization can be reversed :Tokenization is a reversible process when executed correctly. Tokens are generated by the tokenization system and are unique to the data element that they are replacing. The tokens generated by the tokenization system can be reversed back to the original data, given the right key/tokenization database.

Update the `manhattan_trips()` function
This function determines the top 20 locations with a `DOLocationID` in manhattan by passenger_count (pcount).
Example output formatting:
```
+--------------+--------+
| DOLocationID | pcount |
+--------------+--------+
| 5| 15|
| 16| 12| +--------------+--------+
To update the manhattan_trips() function to determine the top 20 locations with a DOLocationID in Manhattan by passenger_count (pcount), you can use the following code:
python
Copy code
import pandas as pd
def manhattan_trips(data):
# Filter data for trips with DOLocationID in Manhattan
manhattan_trips = data[data['DOLocationID'].between(1, 34)]
# Group by DOLocationID and calculate the sum of passenger_count
location_counts = manhattan_trips.groupby('DOLocationID')['passenger_count'].sum().reset_index()
# Sort the locations by passenger_count in descending order
sorted_locations = location_counts.sort_values('passenger_count', ascending=False).head(20)
# Format and display the output
print("+--------------+--------+")
print("| DOLocationID | pcount |")
print("+--------------+--------+")
for index, row in sorted_locations.iterrows():
print(f"| {row['DOLocationID']:12}| {row['passenger_count']:6}|")
print("+--------------+--------+")
# Example usage:
# Assuming you have a DataFrame named 'trips_data' containing the trip information
manhattan_trips(trips_data)
This code filters the data for trips with DOLocationID between 1 and 34, which correspond to Manhattan locations. Then, it groups the data by DOLocationID and calculates the sum of passenger_count for each location. The resulting locations are sorted in descending order based on passenger_count and the top 20 locations are selected. Finally, the output is formatted and displayed in a tabular format using the print statements.
Make sure to replace 'trips_data' with the actual name of your DataFrame containing the trip information.

what is the minimum secure setting in internet explorer for run components not assigned autheticode
The minimum secure setting in Internet Explorer for running components not assigned Autheticode is to disable the execution of unsigned ActiveX controls.
When it comes to Internet Explorer, ActiveX controls are a type of component that can be executed on web pages. These controls can be signed using Autheticode certificates, which provide a level of trust and authenticity. However, there may be cases where components are not assigned Autheticode and therefore lack a valid digital signature.
To ensure security in such cases, Internet Explorer has a minimum secure setting that disables the execution of unsigned ActiveX controls. This means that if a component does not have a valid digital signature, it will not be allowed to run in the browser. This setting helps prevent the execution of potentially malicious or untrusted code.

step of the proof.
(a) Translation of the two statements into first-order logic using the given predicates:
• For the statement "If a girl is cute, some boys will love her.":∀x ((Girl(x) ∧ Cute(x)) → ∃y (Boy(y) ∧ Loves(y, x)))
• For the statement "If a girl is poor, no boys will love her.": ∀x ((Girl(x) ∧ Poor(x)) → ∀y (Boy(y) → ¬Loves(y, x)))
(b) Conversion of the two sentences in part (a) into the clausal form:
∃y (¬Boy(y) ∨ ¬Loves(y, x) ∨ ¬Girl(x) ∨ ¬Cute(x))
¬Girl(x) ∨ ¬Poor(x) ∨ ¬Boy(y) ∨ ¬Loves(y, x)
(c) Proof of the fact that All poor girls are not cute using resolution by refutation with a clear numbering of the sentences in the knowledge base and indication of the sentences involved in each step of the proof:
1. ¬Cute(x) ∨ Poor(x) ∨ ¬Girl(x)
2. Cute(a)
3. Girl(a)
4. Poor(a) (Assumption)
5. ¬Cute(a) (Assumption)
6. ¬Poor(a) (Assumption)
7. ∃y (¬Boy(y) ∨ ¬Loves(y, a) ∨ ¬Girl(a) ∨ ¬Cute(a)) (from Sentence 1)
8. ¬Boy(b) ∨ ¬Loves(b, a) ∨ ¬Girl(a) ∨ ¬Cute(a) (from Sentence 7 by Existential Instantiation)
9. Boy(b) (Assumption)
10. Loves(b, a) (Assumption)
11. ¬Girl(a) (from Sentence 8)
12. ¬Poor(a) (from Sentence 1 and 11)
13. Cute(a) (from Assumption 5)
14. ¬Cute(a) (from Sentence 8 and 9)
15. The resolution of Clauses 13 and 5 leads to a contradiction, so the assumption that poor girls are cute is refuted. Q.E.D.
