joining the genre table and the instrument table represent?
genre table:

name
genre_instrument table:
genre_instrument_id
genre id
instrument_id
instrument table:
instrument id
name
Answers
Every combination of each genre with each instrument, even those that are not represented in the genre_instrument table
Explanation:
The CROSS JOIN clause creates a combination of every row from two or more different tables. Determining the number of results in a result set for a CROSS JOIN is as simple as the product of the number of records in each table.
Even those that are not included in the genre instrument table, every conceivable pairing of a given genre and instrument.
What is a CROSS JOIN?The Cartesian product of the rows from the joined tables is what the CROSS JOIN returns. In other words, rows that combine every row from the first table with every row from the second table will be generated.
Even those that are not included in the genre instrument table, every conceivable pairing of a given genre and instrument
Each row from two or more tables is combined using the CROSS JOIN clause. The product of the number of records in each table can be used to calculate the number of results in a result set for a CROSS JOIN.

Answers
Answer:
A translation lookaside buffer (TLB) is a memory cache that is used to reduce the time taken to access a user memory location.[1] It is a part of the chip's memory-management unit (MMU). The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache. A TLB may reside between the CPU and the CPU cache, between CPU cache and the main memory or between the different levels of the multi-level cache. The majority of desktop, laptop, and server processors include one or more TLBS in the memory-management hardware, and it is nearly always present in any processor that utilizes paged or segmented virtual memory.
Space and time overheads arise from use of paging, and how the Translation Lookaside Buffer (TLB) mitigates the time overheads contains the most recent jvm to memory address translations.
What is Translation Lookaside Buffer?A computer cache called a translation lookaside buffer (TLB) is employed to speed up the process of accessing memory locations. t is a component of the program memory on the semiconductor.
