Answer:
A.
Explanation:
The rest is nearly impossible to detect or not worth the time.
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.
Answer:
=IF( B7 = 12, ( IF( B10 = 10,"YES", "")), 7) and PRESS ENTER
Explanation:
the above logical if function checks the following
-IF cell B7 is 12, if true, check the value of cell B10, IF cell B10 contains 10 the function should produce YES as output to whatever cell selected, IF B10 is not 10 output of the function should be an empty string, IF B7 is not equal to 12 the the output of the function should be 7.
Answer:
The correct answer to the following question will be CAD.
Explanation:
CAD - It stands for Computer-aided Design. CAD is a software used for creating some 3D designs, creative drawing or some technical illustrations and is basically used by the engineers and artists.
Many projects based on electronic can be designed with the help of this software, electronic parts like circuit boards, etc.
Various types of CAD are as follows :
- 2D (Two dimensional)
- 3D (Three dimensional)
- 3D wire frame
- Solid modeling
This enables efficiency in design's quality, also increase in engineer and artist's productivity. So, many of the computer programs should recommend the Computer-aided design software to there project partners for some 3D and effective look on their project.
