Consider the following code example: SELECT vendor_state, vendor_city, vendor_name, COUNT(*) AS invoice_qty, SUM(invoice_total) AS invoice_average FROM invoices JOIN vendors ON invoices. vendor_id = vendors. vendor_id WHERE vendor_state < 'e' GROUP BY vendor_state, vendor_city, vendor_name HAVING SUM(invoice_total) > 500 ORDER BY vendor_state, vendor_city, vendor_name Although this query runs as coded, it contains this logical error:

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
