What does mean Buffer Size And Adapter?

[z_o_o_m]

buffer size - program reads and uploads files in smaller pieces. If you have faster internet, it can send bigger piece at once. So this value should be around the same as your upload speed per file.
adapter - if you have more network cards in your computer, you can choose which one should be used to connect to internet
