Transmission Basics (Chapter 3 of 5th Edition)

A device which both transmits and receives signals (e.g a NIC) is known as a _______________

• Transponder

• Transfixer

• Transceiver

• Mixed-Mode Receiver

The term "Transmit" means ____________________

• To issue signals along a network medium

• To transfer data from a laptop to a server

• To receive data from a node on your network

• To transfer data back to your office while on the road.

Computers generate and interpret signals as electrical current, the pressure of which is measured in ________________?

• Ohms

• Bits

• Watts

• Volts

In Analog signals, voltage varies continously and appears as a __________________

• Cube shape

• Wavy line

• Circle

• Sphere

The feature of a wave which is a measure of it's strength at any given point in time is it's _________________

• Temperament

• Amplitude

• Altitude

• Attitude

The number of times a wave's amplitude cycles from it's starting point through it's highest amplitude and it's lowest amplitude and back to it's starting point over a fixed period of time is known as it's _______________

• Frequency

• Optimalcy

• Pleasantness

• Fahrenheit

Frequency is expressed in what unit?

• Watts

• Volts

• Cycles per second (Hertz)

• Mobility

The distance between corresponding points on a wave's cycle is called it's _________________________________________

• Magnitude

• Point distance

• Wavelength

• Spatial Difference

A wave’s wavelength is inversely proportional to its frequency. In other words, the higher the

frequency, the shorter the wavelength. Which of these frequencies has the shortest wavelength?

• 10 Hz

• 30 MHz

• 20 GHz

• 5 MHz

The progress of a wave over time in relationship to a fixed point is known as it's ____________

• Phase

• Length

• Magnitude

• Distance
