Memory allocation Doubt
Consider the requests from processes in given order $300K$, $25K$, $125K$ and $50K$. Let there be two blocks of memory available of size $150K$ followed by a block size $350K$. Which of the following partition allocation schemes can satisfy above ... a process of $200KB$ then a process with size $100KB$ can't be allocated to this partition. Which approach is correct?

Go-BackN sliding window protocol
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. (I am getting 10Mbps , please confirm it)
