What are some ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1)?

a. Separate digital receive and transmit paths onto their own physical channels/circuits b. Modulate receive and transmit channels onto different carrier frequencies, thus allowing FDX on the same physical medium c. Separate transmit and receive channels on the same physical medium by separating them in time (i.e., TDM) d. All of the above

Answer:

d. All of the above

Explanation:

Physical layer is the lowest layer of the OSI reference model that deals with the setup of physical connection to the network and with transmission and reception of signals.

Full duplex (FDx) is a bidirectional type of communication system where two end nodes send and receive data signals at the same time, and a single carrier is simultaneously used for dual communication.

To send or receive data, the participating nodes in a Full Duplex system do not have to wait for a free carrier/medium. It employs a medium that has at least two internal channels - one for sending and one for receiving.

Based on the above explanations, options A, B and C are valid and are correct ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1). There all of them are correct.

Alexxandr [17]

The type of network that consists of multiple Windows computers that share information is peer-to-peer. In this network, the computer serves as an authoritative source of user information.

<h3>Peer-to-peer computer networks</h3>

A peer-to-peer (P2P) network can be defined as a type of network where the computer acts as a source of user information.

In P2P, a cluster of different computers are linked and they have the same permissions for processing data in the network.

This type of computer network (peer-to-peer computer network) has been created to serve and/or receive data.

The sum of all the minterms of a boolean function of n variables is equal to 1.
Aleksandr-060686 [28]

The answers are as follows:

a) F(A, B, C) = A'B'C' + A'B'C + A'BC' + A'BC + AB'C' + AB'C + ABC' + ABC

= A'(B'C' + B'C + BC' + BC) + A((B'C' + B'C + BC' + BC)

= (A' + A)(B'C' + B'C + BC' + BC) = B'C' + B'C + BC' + BC

= B'(C' + C) + B(C' + C) = B' + B = 1


b) F(x1, x2, x3, ..., xn) = ∑mi has 2n/2 minterms with x1 and 2n/2 minterms

with x'1, which can be factored and removed as in (a). The remaining 2n1

product terms will have 2n-1/2 minterms with x2 and 2n-1/2 minterms

with x'2, which and be factored to remove x2 and x'2, continue this

process until the last term is left and xn + x'n = 1

patriot [66]

Answer:

Digital Certificate is the correct answer of this question.

It is used to cryptographically attach public key rights to the organization that controls it.

<u>For example</u>:- Verisign, Entrust, etc.

  • An appendix to an electronic document that is used for authentication purposes.
  • A digital certificate's most frequent use is to confirm that an user sending a message is who he or she appears to be, and provide the recipient with the means to encode a response.

masya89 [10]

Answer:

The answer is "Fiber Optic Cable".

Explanation:

In the given question options are defined, but in these options, there is some error.

The optical fiber cable is also known as internet wiring, which includes fiber strands inside an isolated housing. It is used to transferring data at a very high speed. This cable is developed for long-range data networking, high-performance connectivity, and multimedia, and other choices are wrong that can be described as follows:

  • A modem is used to transmits data over a network, that's why it is wrong.
  • Router is used to transport traffic between your computer and the internet, that's why it is wrong.
