We want to use an online grammar checking tool, which takes each word from the client and sends it to the web server. The available network bandwidth between the client and the server is 2 Gbps. What should be the maximum allowed size(in MBs) of a document containing the word sent from the client to the server per second for the grammar check? (Use: 1KB= 1000Bytes, 1MB=1000KB and so on.)

Question 11

+3 marksNumerical answer

Consider a client which is located 3000 km from the server makes a request through the cable. Suddenly after the request reaches the server, the cable breaks and the response is now to be sent to the client via air. This change of medium caused an additional delay of 47 ms at the server end. How long will the client have to wait before receiving the response (in ms)? ( speed on cable = 2e8 m/s and in air 3e8 m/s)
