computer science Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file file is already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: a. How is the logical-to-physical address mapping accomplished in this system? (For the indexed allocation, assume that a file is always less than 512 blocks long.) b. If we are currently at logical block 10 (the last block accessed was block 10) and want to access logical block 4, how many physical blocks must be read from the disk? Verified answer
computer science Design and implement an application that reads an integer value representing a year input by the user. The purpose of the program is to determine if the year is a leap year (and therefore has 29 days in February) in the Gregorian calendar. A year is a leap year if it is divisible by 4, unless it is also divisible by 100 but not 400. For example, the year 2003 is not a leap year, but 2004 is. The year 1900 is not a leap year because it is divisible by 100, but the year 2000 is a leap year because even though it is divisible by 100, it is also divisible by 400. Produce an error message for any input value less than 1582 (the year the Gregorian calendar was adopted).

SQL allows a data analyst to communicate with a database in order to retrieve and manipulate data.
What is structured query language SQL in database design?Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
How is SQL used by data analysts?Though SQL is commonly used by engineers in software development, it's also popular with data analysts for a few reasons: It's semantically easy to understand and learn. Because it can be used to access large amounts of data directly where it's stored, analysts don't have to copy data into other applications.
Why SQL is a Structured Query Language?Structured Query Language (SQL) is a specialized programming language designed for interacting with a database. SQL allows us to perform three main tasks: To define the scope of the database. To add, delete or modify the data in the database.
