   A user is comparing two network connections. Connection A has a throughput of 250 Mbps. Connection B has a throughput of 0.25 Gbps. The user wants the faster connection for large file transfers. Which of the following is the correct recommendation?

   • AEither connection will provide the same throughput because 0.25 Gbps equals 250 Mbps.
   • BChoose Connection A because 250 Mbps is faster than 0.25 Gbps.
   • CChoose Connection B because Gbps is a larger unit than Mbps.
   • DThe comparison cannot be made because Mbps and Gbps measure different aspects of the connection.

   A user is comparing two processors for a new laptop. Processor A has a clock speed of 2.4 GHz. Processor B has a clock speed of 2400 MHz. The user asks the technician which processor is faster. Which of the following is the most accurate response?

   • AProcessor A is faster because 2.4 GHz is a higher number than 2400 MHz.
   • BProcessor B is faster because MHz is a smaller unit, so more of them means more speed.
   • CThe comparison cannot be made because GHz and MHz measure different properties.
   • DThey are the same speed because 2.4 GHz is equal to 2400 MHz.
