Wireless transmission refers to that the signal is contained within an enclosed physical path.
True
False
A wireless transmission media that is commonly used in TV remotes, wireless mouse, keyboard, and printer.
Infrared waves
Radio waves
Microwaves
Ultraviolet waves
Unbound Transmission media are microwave, radio wave, and infrared.
True
False
It is also known as start/stop transmission that does not use a clock to match data between the source and destination.
Serial Transmission
Asynchronous Transmission
Parallel Transmission
Synchronous Transmission
Serial transmission is good for transmitting data over a longer distance.
True
False
This form of guided media is not affected by the external magnetic field.
Twisted Pair

None of the choices
Parallel data transmission is practical for long-distance communication.
True
False
It refers to loss of energy as signal transmits outwards.
Bandwidth
Noise
Attenuation
Radiation
Both synchronous and asynchronous transmissions are subclasses of parallel transmission.
True
False
They are also known as terrestrial networks.
P2P
Multicast
Unicast
Broadcast
Transmission technologies refer to the physical layer protocol duties such as modulation, demodulation, line
coding, and error control; or higher-level protocol duties such as digitizing analog signals, and data compression.
True
False
This transmission happens when messages can only be exchanged in real time.
Serial Transmission
Asynchronous Transmission
Parallel Transmission
Synchronous Transmission
What transmission technology is used for two locations that are required to securely send very sensitive and confidential data?
Broadcast
Unicast
Multicast
P2P
It is a type of transmission where only two machines interact over the established route.
Broadcast
Unicast
Multicast
None of the choices
A type of transmission where data is sent bit by bit from one computer to another in bi-direction.
Serial
Parallel
Synchronous
Asynchronous
It refers to the data carrying capacity of a channel or medium.
Attenuation
Noise
Bandwidth
Radiation
It defines the set of equipment, transmission media, and procedures that ensures that a specific sequence
of events in a network occurs in the proper order to produce the intended results.
Network Protocol Stack
Network Protocol
Network Standard
Network Architecture
This data transmission is extremely fast because all the bits of the data word are transferred simultaneously.
Serial Transmission
Multicast Transmission
Parallel Transmission
Broadcast Transmission
Transmission media is classified into unguided and wireless media.
True
False
A wired communication media in which transmission of signals takes place in the electrical form over the metallic conducting wires.
Twisted Pair
Coaxial
Fiber Optic
None of the choices
It is a data transmission mode in which the data can flow only in one direction.
Duplex
Simplex
Semi-Duplex
Full-Duplex
A wired communication media in which transmission of signals takes place in the electrical form over the inner conductor of the cable.
Coaxial
Twisted Pair
Fiber Optic
None of the choices
A transmission media for wireless communication that can penetrate buildings easily so they are widely used both for indoors and outdoors.
Radio waves
Infrared waves
Microwaves
Ultraviolet waves
A data transmission mode where in each station can both transmit and receive the data at a time.
Half-Duplex
Full Duplex
Duplex
None of the choices
A wireless communication media in which the sending and receiving antennas need to be properly aligned with each other for data transmission.
Infrared waves
Radio waves
Microwaves
Ultraviolet waves
