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.
The VLOOKUP function has these arguments: =VLOOKUP(lookup_value, table_array, col_index_num, range_lookup) The range_lookup argument is optional, often overlooked, but very useful. This is because range_lookup determines whether VLOOKUP returns an approximate match or an exact match.
