Blair writes a paragraph about data transmission in her Computer Science examination. Use the list given to complete Blair’s paragraph by inserting the correct five missing terms. Not all terms will be used. Terms can be used more than once. • duplex • half-duplex • parallel • serial • simplex data transmission is when data is transmitted a single bit at a time. data transmission is when multiple bits of data are sent all at once. If a user wants to transmit data over a long distance, with the highest chance of accuracy, data transmission should be used. If data needs to be transmitted in one direction only, for example from a computer to a printer, data transmission should be used. If a user has a large amount of data to transmit and this needs to be done as quickly as possible data transmission should be used. [5] 7 Question 4 starts on page 8.
