Answer: A. Multicast
Explanation:
Here we are given a situation where it is necessary for the device to stream media to all the PCs connected across the LAN. But as the they are unable to stream the media then it is a problem in the multicast TCP/Ip technology.
Multicasting enables to transfer information or messages from one to many or many to many. Here as a single device is responsible for streaming the content to other PCs across the LAN, therefore it is necessary that multicast has been properly implemented.
Option B is incorrect as it is not a scenario of broadcast as in broadcasting all the receivers must get the streaming however here if a PC does not want to receive the media stream it cannot receive for which multicasting is required.
Option C is incorrect as here we are not talking of one to one communication.
Option D is incorrect as here we cannot have more than one route to send the media content except the LAN.
The kind of material that is used for DRAM (dynamic random-access memory) is metal-oxide-semiconductor.
<h3>What is DRAM?</h3>
DRAM was invented in 1968. It is a type of RAM used in modern computers and laptops. It is a type of random access memory. Its name is dynamic random access memory.
Metal-oxide-semiconductor is used in making the transistors and capacitors of the DRAM, which are used to store the data. They hold a bit of the data in these capacitors and transistors.
Thus, the material that is used is metal-oxide-semiconductor to make DRAM (dynamic random-access memory).

Connections, allow separate systems to communicate directly with each other, eliminating the need for manual entry into multiple systems. They do not entirely eliminate information redundancy, but they do ensure information consistency among multiple systems.
