Answer:
1. A parallel full-duplex synchronized data transmission is the parallel bidirectional transmission which is used for short distances. The parallel transmission of the data needs a lot of wires, and its 1 wire per bit, as well as it is expensive. The data over long distances might become skewed. And it can be used inside LAN, where the computer and server can talk to each other.
2. The serial full-duplex asynchronized transmission is a bidirectional serial transmission of the data over a full-duplex connection. And the messages are sent by both sides serially and can be sent anytime as well as at irregular intervals. This requires a single wire. A perfect example is while we talk through a telephone.
3. The synchronized full-duplex serial transmission is a bidirectional data transmission one by one in a serial manner and at regular intervals. And it requires a single wire. The speed of the data transmission depends upon the bandwidth of the full-duplex channel. The perfect example is full-duplex walky-talky. In this, the sender sends serially messages in a synchronized manner, and the same thing is done by the receiver, and at the same time, and as a response to each of the messages, the receiver receives. This can create a little confusion in real-time.

Answer:
A sympton of a failing power supply is The computer sometimes does not turn on.
Explanation:
All right, the power supply is the terminal that receives electric current to process it and distribute it to the different parts of the hardware that compose the computer. When it fails, the current is not distributed and doesn't reach the different pieces of hardware. Therefore, option D) is the correct one. Another error that could be related is the malfunction of fans but it could be related to wires more than the power itself.
I’d go for (C): Wastes from nuclear
power plants are harmful and difficult to manage.
When nuclear reactors ‘safety systems are not properly
installed and maintained, a nuclear reactor could emit harmful amounts of
radiation into the environment. The leak of radiation end result could be
catastrophic especially if a containment field were to suddenly rapture. The
main disadvantage of this is the difficulty to manage the nuclear waste and might
take years to eliminate its radioactivity.
