Which term describes communication between two points?
- A.
Channel
- B.
Trough
- C.
Delta
- D.
Confluence
Correct Answer
A. ChannelExplanation
A channel is a term used to describe communication between two points. It refers to a pathway or medium through which information is transmitted from one point to another. In this context, the other options (trough, delta, and confluence) do not accurately describe communication between two points. A trough is a long, narrow depression or pathway, typically used to refer to a water channel. Delta and confluence are geographical terms used to describe the formation of landforms, and they do not specifically pertain to communication. Therefore, the correct answer is channel.Rate this question:

How is a phone signal kept from unauthorized readers?
- A.
Partitioning
- B.
Encryption
- C.
Crosstalk
- D.
Authentication
Correct Answer
B. EncryptionExplanation
Encryption is used to keep a phone signal from unauthorized readers. It involves converting the data into a code that can only be deciphered with a specific key or password. This ensures that even if someone intercepts the signal, they won't be able to understand the information being transmitted. Encryption is an effective method for maintaining the privacy and security of phone signals.Rate this question:

What kind of cable uses light to send messages?
- A.
HDMI
- B.
Fiber Optic
- C.
Component
- D.
Ethernet
Correct Answer
B. Fiber OpticExplanation
Fiber optic cables use light to send messages. These cables contain thin strands of glass or plastic that transmit data by converting electrical signals into light signals. The light signals then travel through the cable, bouncing off the walls of the cable due to total internal reflection. This allows for fast and efficient transmission of data over long distances without any loss in signal quality. HDMI, Component, and Ethernet cables, on the other hand, use electrical signals to transmit data.Rate this question:

Mobile phones use which device for additional storage?
- A.
Sony MiniDisc
- B.
Flash Memory
- C.
Bluetooth
- D.
Hard Drive
Correct Answer
B. Flash MemoryExplanation
Mobile phones use flash memory for additional storage because flash memory is a type of non-volatile storage that can retain data even when power is turned off. It is compact, lightweight, and has no moving parts, making it ideal for use in mobile devices. Flash memory can be easily integrated into the design of mobile phones, providing users with the ability to store and access large amounts of data such as photos, videos, and applications.

What term is used for the level of radio waves?
- A.
Hertz
- B.
Frequency
- C.
GSM
- D.
SS7
Correct Answer
B. FrequencyExplanation
Frequency is the term used to describe the level of radio waves. It refers to the number of cycles or oscillations of a wave that occur in a second. The higher the frequency, the more cycles occur in a given time period, resulting in a higher pitch or energy level of the radio wave. Hertz is the unit of measurement used to quantify frequency. GSM and SS7 are not related to the level of radio waves and therefore not the correct answer.Rate this question:

What signaling method varies the carrier frequency?
- A.
Frequency Reuse
- B.
Frequency Modulation
- C.
Partitioning
- D.
Half-Rate
Correct Answer
B. Frequency ModulationExplanation
Frequency modulation is a signaling method that varies the carrier frequency. In frequency modulation, the frequency of the carrier signal is modified in accordance with the variations in the amplitude of the modulating signal. This modulation technique is commonly used in radio broadcasting and telecommunications to transmit information through the variation of frequency. By varying the carrier frequency, frequency modulation allows for efficient transmission of data and provides resistance to noise interference.Rate this question:

What battery has a longer life cycle than most others?
- A.
Lithium-Ion Battery
- B.
Nickel Cadmium
- C.
Lithium Polymer
- D.
Nickel Metal Hybrid
Correct Answer
A. Lithium-Ion BatteryExplanation
Lithium-Ion Battery has a longer life cycle than most others. This is because lithium-ion batteries have a higher energy density and can store more energy compared to other battery types. They also have a lower self-discharge rate, meaning they can retain their charge for longer periods of time when not in use. Additionally, lithium-ion batteries have a longer overall lifespan, with the ability to be charged and discharged hundreds of times before their performance starts to degrade.Rate this question:
