Several times a day, merge all developers’ working copies into a single common mainline. This facilitates the detection of problems. You should know about how things work.

7. What is the definition of long polling?

Long polling is a method of development that sends data from the server to the client. When a client sends a request and the desired information is unavailable, the system waits and responds rather than returning empty requests.

A program that allows creating and maintaining both server and client-side applications. This is a crucial notion that you should understand.
