Question
In a client-server application on the web using sockets, which must come up first?
Solution
In a client-server application on the web using sockets, the server must come up first. Here's why:
-
The server is the system that provides resources or services. In the context of web applications, it's the system that hosts the website or application.
-
The client is the system that requests these resources or services. In the context of web applications, it's the user's browser.
-
When using sockets for communication, the server must be up and running first because it needs to create a socket and bind it to a specific address and port. This is known as "listening" for incoming connections.
-
Once the server is listening, clients can then create their own sockets to connect to the server's socket. This is known as "connecting" to the server.
-
If the server is not up and running (i.e., if it's not listening for incoming connections), then clients cannot connect to it. This is why the server must come up first in a client-server application on the web using sockets.

When an application uses a TCP socket, what transport services are provided to the application by TCP? Check all that apply.Best effort service. The service will make a best effort to deliver data to the destination but makes no guarantees that any particular segment of data will actually get there.Loss-free data transfer. The service will reliably transfer all data to the receiver, recovering from packets dropped in the network due to router buffer overflow.Flow Control. The provided service will ensure that the sender does not send so fast as to overflow receiver buffers.Real-time delivery. The service will guarantee that data will be delivered to the receiver within a specified time bound.Throughput guarantee. The socket can be configured to provide a minimum throughput guarantee between sender and receiver.Congestion control. The service will control senders so that the senders do not collectively send more data than links in the network can handle.
