• True

• False

Which of the following is not a type of wireless technology? Mark only one oval.

• Bluetooth

• UTP

• Satellite

• Cellular 3G/4G/5G

Match the transmission system classification with its timing category. The transmission timing can occur at any time with an arbitrary delay between the transmission of two data items.

• Asynchronous

• Isochronous

• Synchronous

• Semi-synchronous

Match the transmission system classification with its timing category. The transmission timing occurs at regular intervals with a fixed gap between the transmission of two data items.

• Asynchronous

• Isochronous

• Synchronous

• Semi-synchronous

Match the transmission system classification with its timing category. The transmission timing occurs continuously with no gap between the transmission of two data items.

• Asynchronous

• Isochronous

• Synchronous

• Semi-synchronous

Random electromagnetic radiation is called ______________. Mark only one oval.

• noise

• shielding

• signals

• reflection

• interference

Two broad classes are used to distinguish between physical media (such as copper wiring or optical fibers) that provide a specific path and radio transmissions that travel in all directions through space. These classes are referred to using these terms: Mark only one oval.

• AM & FM

• electrical & electromagnetic

• guided & unguided

• wired & optical

Why does light travel around a bend in an optical fiber? Mark only one oval.

• Light cannot escape an optical fiber.

• Light reflects when the angle of incidence is greater than the critical angle.

• Light refracts when the angle of incidence is less than the critical angle.

• Light waves do not disperse in an optical fiber.

• True

• False
