what are characteristics of distributed file system ?its users, servers and storage devices are dispersed

A data analyst wants a quick summary of the structure of their data frame, including the column names and the number of rows and variables. The function that should used is str(). Because the str() function returns a summary of the structure of a dataframe, including column names, the number of rows and variables, and the type of data stored.

Data in the quest of knowledge is a collection of discrete values that transmit information, describing amount, quality, fact, statistics, other fundamental units of meaning, or just simply sequences of symbols that may be further understood. A datum is a specific value contained in a group of data. Typically, data is arranged into tables or other structures that provide it greater context and meaning and can be used as data in other, larger structures. It's possible to use data as variables in a computation. Data can represent measurements or abstract concepts. Data are frequently employed in economics, science, and practically every other aspect of human organizational activity.

It is considered as poor programming practice as it again to save years as two digits, as was done in the Y2K bug, as this could result in uncertainty and loss of data.

It is seen as poor programming practice to save years as two digits, as was done in the Y2K bug, as this might result in ambiguity and data loss. Assuming that the decade 2000 would've been represented as "00" led to the Y2K problem, which could have led software to mistakenly read the year as 1900 rather than 2000.

It is advised to adopt a format that can accept diverse types of dates and times, such as the ISO 8601 standard, or to save years using four digits in order to prevent these types of problems.

In light of the Y2K issue, it can be determined that storing years as two quantities was a mistake.

Program A and program B display identical values is the best compares the values displayed by programs A and B.

The phrase "identical values" means that the values displayed by both programs A and B are exactly the same. This means that if the programs are displaying any kind of data, such as numbers, strings, or other types of data, the data displayed by both programs must be exactly the same.

For example, if both programs are displaying a list of numbers, the numbers in the list must be in the same order and must have the same values in both programs. If both programs are displaying a string, the string must be exactly the same in both programs, with no differences in capitalization, spacing, or any other aspect of the string.

In contrast, if the programs display the same values in different orders, it means that the values are the same, but they are not arranged in the same way in both programs. For example, if both programs are displaying a list of numbers, the numbers in the list may be the same, but they may be arranged in a different order in each program.

If the programs display the same number of values, but the values differ, it means that the programs are displaying the same number of values, but the values themselves are different.
