Which mechanisms do we use to transport binary data and memory addresses?
Sav [38]

Answer:

The External Data Bus  is used to transport binary data and Address bus is used to transport memory addresses.

Explanation:

  • External Data Bus is a combination of data bus and external bus. Data bus is used to carry data and instructions between two or more components in the system e.g. CPU and all other computer components.
  • External bus is also called expansion bus. It is used to connect external components to the computer. Its a communication medium between CPU and other components. These components can be peripheral device like USB or flash memory.
  • So External Data Bus is used to transport data between CPU and external components. It is a primary communication pathway for data in a computer. The external data components are connected to this bus and the instruction or data on this bus is available to all external components. But the data communication is slower as compared to that of internal bus.
  • Address Bus carries physical location or address of data and transports memory addresses. Processor uses address bus when it wants to read data from memory or write data to the memory by sending a read/write signal by placing the read/write address of the specific memory location on the address bus.

It is different from other attacks  such as (DoS) Denial of Service attacks, in which it utilizes an unique Internet-connected device ( single network connection) to stream a target with the malicious traffic.
  • So in DDoS, multiple systems are involved in the attack and hence we can conclude that as the answer.
