Final answer:
Packets are sent to different ports on a computer system based on the hash of their packet ID.
Step-by-step explanation:
The subject of this question is Computers and Technology and the grade level is High School.
In computer networks, packets are sent from one device to another. Each packet contains a packet ID, which is used to identify the packet. The hash of the packet ID is used to determine which port the packet should be sent to on a computer system.
For example, let's say we have a computer system with four ports and the hash function generates values from 0 to 3. If the hash of a packet ID is 2, the packet will be sent to port 2 on the computer system.
The statement is describing a technique known as "hash-based load balancing" or "hash-based packet distribution." In this approach, packets are distributed among different ports or servers based on the hash value computed from some characteristic of the packet, often the packet ID or source/destination addresses.
This technique is commonly used in network load balancing to efficiently distribute incoming network traffic across multiple servers or ports, preventing overload on a single server and improving overall system performance.
