In some queries, you may not be able to grasp the exact value of the query, such as Baidu search input key words can query out the relevant results, this query is called Fuzzy query.The fuzzy query uses the LIKE keyword to retrieve the required rows of data through character matching.

The GPU is designed to handle multiple threads at one time, and these threads are much slower to handle, but the program can take advantage of parallelism to perform faster, just like a supercomputer.Today, the CPU has been able to perform parallel operations, and multicore is popular, but they are mostly optimized for single-threaded processes, says Hulk.GPU terminology did not appear until 1999, but there were ea
