The definition for latency is simple: Latency = delay. Itâs the amount of delay (or time) it takes to send information from one point to the next. Latency is usually measured in milliseconds or ms. Itâs also referred to (during speed tests) as a ping rate.
VLOOKUP is a powerful Excel function that allows you to look for a specified value in one column of data inside a table, and then fetch a value from another column in the same row.
= VLOOKUP ( lookup_value , lookup_array , HLOOKUP ( lookup_value , lookup_array , 2 , FALSE ) , FALSE ) The syntax for VLOOKUP HLOOKUP is fairly simple conceptually. If you understand both VLOOKUP and HLOOKUP, all you are doing is replacing the column_reference component of VLOOKUP with the HLOOKUP formula.
