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.
Answer:
True
Explanation:
C language is developed with the help of UNIX in 1972. It was developed by Denis Ritchie at Bell labs. many languages are developed with the help of C Platform. Such as C++, C sharp and Java.
There is block cipher kind of mode of operation. The block cipher mode of operating requires that both the message sender and receiver is exchanged is the (CTR) Counter.
<h3>What is the Counter (CTR)?</h3>
This is known to be a common block cipher mode of operation. It often needs that both the message sender and receiver to have a kind of access a counter, that helps to computes a new value whenever a ciphertext block is been exchanged.
The disadvantage of CTR is known to be the fact that it needs a synchronous counter necessary for both the sender and receiver.
