1. What does “telecommunications” primarily refer to?
A. Mechanical signal transfer
B. Optical storage systems
C. Transmission of information over distance
D. Local data processing
Telecommunications involves sending voice, data, or video
signals over distance using electronic systems.
2. Which signal type uses continuous waveforms?
A. Digital
B. Packet
C. Binary
D. Analog
,Analog signals vary continuously and represent data through
waveform changes.
3. Which unit measures bandwidth?
A. Volts
B. Amperes
C. Hertz
D. Ohms
Bandwidth is the range of frequencies measured in hertz (Hz).
4. Which device converts digital data to analog signals?
A. Router
B. Switch
C. Modem
D. Hub
A modem modulates and demodulates signals for
transmission over analog lines.
5. What does latency measure?
A. Signal strength
B. Data size
C. Transmission delay
D. Frequency
Latency is the time it takes for data to travel from source to
destination.
, 6. What is attenuation?
A. Signal amplification
B. Signal encryption
C. Loss of signal strength
D. Signal encoding
Attenuation occurs as signals weaken over distance.
7. Which medium is least affected by electromagnetic
interference?
A. Coaxial cable
B. Twisted pair
C. Fiber optic cable
D. Copper wire
Fiber optics transmit light and are immune to EMI.
8. What is a baud rate?
A. Bits per second
B. Signal changes per second
C. Packets per second
D. Frames per second
Baud rate measures how many signal changes occur per
second.
9. What is the primary function of a repeater?
A. Route data
B. Encrypt data
