Digital signature is typically put on the one-way hash of the message, instead of on the message directly. One of the reasons is the cost because signing a short hash value is more efficient than signing a message that can be very long. Bob says that his message is always short, so he decides to directly sign the message, rather than signing its hash. (1) Without knowing Bob’s private key, we want to generate a pair (m, s), where s is Bob’s signature on m, and m can be anything? Assume s is a random number, and describe how you calculate m. (2) If Bob signs the one-way hash of the message, can you still generate a pair (m, s)?

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server.so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.

Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. thus your code should put 11 + 22 + 33 + + 4949 + 50*50 into total. use no variables other than k and total.
