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

labwork [276]

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.

Suppose an 80286 microprocessor is in protected mode. How it is switched back

iris [78.8K]

Answer:

hardware-initiated reset

Explanation:

Once in protected mode, the 80286 is designed to remain there until it is reset by hardware.

External hardware can be designed so that software can cause such a reset. In the 1984 PC/AT, such hardware combined with code in the BIOS allowed real mode re-entry and returned execution control to the program that caused the reset.

A troubleshooting strategy that removes components from a system in order to get back to a basic configuration is called module

Semmy [17]

Answer:

B. False.

Explanation:

Troubleshooting strategy is a technique used to discover the cause of defeat in a system. The technician must learn to improvise with these strategies to solve a system problems.

Module replacement is a type of troubleshooting strategy that replaces a component with unknown status with another component with good status to determine the cause of the problem.

Removing a component from a system to get back to its basic configuration helps to eliminate factors that may make a computer problem difficult to solve.
