True. The dup system call can be used in a forking TCP server to make a copy of the socket descriptor from the parent process and pass it to the child process. This allows the child process to send responses to the client without needing to make a new socket descriptor.
A common way to create a network is to use the Transmission Control Protocol (TCP). When TCP is used, a server is responsible for administering and managing the communication between the client and the server. The server must be able to handle multiple clients and ensure that all clients receive fast responses. This means that the server needs an efficient way to communicate with all clients. This is where the Dup system comes into play.
The ability to make a copy of the socket descriptor on a TCP server means that the server does not have to create a new socket descriptor for each client. This means that the server can handle multiple clients without increasing memory usage. This makes the server more efficient and able to handle network overhead more effectively. This also means that the server can respond to clients faster, which means that end users have a better experience.
