Data is often sent faster by character devices than by block devices. Is this statement true or false?

This value keeps track of the total number of I/O operations and the number of source-level lines that have been run so far.

Data is normally transferred faster by character devices than by block devices. Is this statement true or false?

Determines how fast I/O operations may be executed.

Generally, character devices transport data faster than block devices. Is this true or false?

Address ValidationImagine you get a data set from a client that contains addresses from 150 countries all around the world and your task is to verify it, the data is stored in 3 fields – Address Line, City, and ZIP code. What you also have available is an address verification solution for each country, but the data set does not include the country code. Your task is to design a logic that will process the data and find the related country for each record, so they can be run through the relevant validation component. Think of the most efficient way. Describe your solution proposal ideally in an algorithmic way (e.g. using appropriate UML diagrams, pseudo-code, list of steps…)Hint: Running all of those 150 address verification components against each record is not considered efficient

The stream manipulators dec, oct and hex affect only the next integer output operation T/F
