Q

These media are usually solid linear conductors that physically connect the transmit and received signals.

A

Wired

17
Q

_______ media has the limitation of distance but has a better reliability due to the visible physical connection and less susceptive to atmospheric noise being insulated.

A

Wired

18
Q

Real world examples of wired media are:

A

landline wires,
coaxial cables,
ethernet (LAN) cables and
fiber optic cables.

19
Q

These media have no material boundaries due to being NOT solid.

A

Wireless

20
Q

These are designed for short or longer distances as depending on the magnitude of the input power that sustains it.

A

Wireless

21
Q

Wireless transmission can be ________ to interference due to being ______ to the elements.

A

susceptive, open

22
Q

The convenience of no physical restrictions due to the nature of this media, is its main draw.

A

Wireless

23
Q

Wireless real world examples are:

A

Wifi,
Infrared,
Microwave Radio,
Satellite,
Bluetooth,
Free-to-Air Broadcast (AM/FM/DTV),

24
Q

In practice, there is going to be a hybrid form of transmission media, wherein some sections are wired and some are wireless.

A

Hybrid Form: Wire + Wireless

25
Q

Those that transverse long distances are usually wired and as it approaches the user or receiver side becomes wireless.

A

Hybrid Form: Wire + Wireless

26
Q

In some cases, it can also be reversed, in such that at the transmission media was wireless and at the user side it became wired.

A

Hybrid Form: Wire + Wireless

27
Q

is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner.

A

Transmission Line

28
Q

The term applies when the conductors are long enough that the wave nature of the transmission must be considered.

A

Transmission Line

29
Q

It has a center conductor covered with an insulator, then braided or solid outer conductor, and then insulation.

A

Coaxial

30
Q

Transmission Lines two possible models:

A
  1. T-Model
