- Which level of access produces the fastest output?Design a program in Python programming language which has the following points. Take input from user a file name with location which is present in client system. Copy the file to the server system with same format. The file can be at any format ( .txt, .jpg, .mp3 etc ). The file received status should be printed on server and sent to client. Use socket programming to perform the task. Paste the code and output snapshot. Server Output: Waiting… Client Output: Enter file name and location to send : d:\r.jpg Sending…. Server Output: Waiting… Receiving… Client Output: Enter file name and location to send : d:\r.jpg Sending…. File Sent to Server.
