The most scrutinized cipher in history is the Data Encryption Standard (DES). Developed by IBM in the 1970s, DES was widely used by the US government and financial institutions to protect sensitive data. However, its strength was eventually called into question due to advances in computing power and a number of successful attacks on the cipher.

As a result, the National Institute of Standards and Technology (NIST) launched a competition in the 1990s to develop a stronger encryption standard. This led to the development of the Advanced Encryption Standard (AES), which is now widely used for data encryption. Despite its flaws, DES played an important role in the development of modern cryptography and remains an important part of the history of encryption. Its weaknesses helped to spur innovation and led to the development of stronger encryption standards that are used today. In conclusion, while the Vigenère cipher, transposition cipher, and keyword mixed alphabet cipher have all been important in the history of cryptography, the Data Encryption Standard (DES) stands out as the most scrutinized cipher due to its widespread use and eventual replacement by the stronger Advanced Encryption Standard (AES).

The ACA  Affordable Care Act uses the number of full-time equivalent (FTE) employees to classify an employer as a large employer.

A full-time equivalent employee is calculated by adding up the hours worked by part-time employees and dividing by 120. So, for example, if a company has 50 full-time employees and 20 part-time employees who work an average of 15 hours per week, the calculation would be as follows 50 full-time employees + (20 x 15 hours per week / 120) = 53 full-time equivalent employees If the total number of full-time equivalent employees is 50 or more, the employer is considered a large employer under the ACA.

The ACA also requires large employers to provide affordable health insurance coverage to their full-time employees or face penalties. Additionally, large employers are required to report information about their health insurance offerings and employee coverage to the IRS and their employees. This reporting requirement is known as the employer shared responsibility provision, or the "employer mandate."

The term that enables you to connect two tables to each other in a database is "table".

In a database, a table is a collection of related data entries or records, each of which consists of several fields or columns that store specific pieces of information. To establish a relationship between two tables, you need to identify a common field that exists in both tables. This field is known as a foreign key, and it enables you to link the records in one table to those in another. By connecting two tables in this way, you can retrieve and combine information from both tables as needed.

In more technical terms, the process of connecting two tables in a database involves creating a relationship between them. There are three types of relationships that can exist between tables: one-to-one, one-to-many, and many-to-many. In a one-to-one relationship, each record in one table corresponds to exactly one record in the other table. In a one-to-many relationship, each record in one table can correspond to multiple records in the other table. In a many-to-many relationship, each record in one table can correspond to multiple records in the other table, and vice versa. To create a relationship between two tables, you typically use a database management system (DBMS) that provides tools for designing and managing the database. Most DBMSs allow you to define the relationship between two tables by specifying the foreign key field in one table and the primary key field in the other table. The primary key field is a unique identifier for each record in the table, while the foreign key field contains the same value as the primary key field in the related table. This creates a link between the two tables that enables you to retrieve data from both tables as needed. In summary, the term that enables you to connect two tables to each other in a database is "table". By creating a relationship between two tables using a common field, you can retrieve and combine information from both tables as needed.
