CLustered index
I have read that clustered index is an index on ordered non-key field of DB. However, in SQL clustered index can be created on Primary key. Infact, by default primary key constraint automatically creates clustered index if one doesn't already exists on the table. So, is SQL clustered index different from the one defined in theory?

MadeEasy Test Series 2018: Computer Networks - Sliding Window
Consider a network connecting two systems, ‘A’ and ‘B’ located 6000 km apart. The propagation speed of media is 2 × 106 mps. It is needed to design a Go-Back-7 sliding window protocol for this network. The average packet size is 107 bits. If network used as its full capacity, then the bandwidth of network is__________ Mbps
