1833.We want to compare the performance of a single threaded disk server with a multithreaded 1. Suppose the server takes 25 ms to receive a request for work from client, dispatch the request for processing and actual data request processing when reqd. Data is in main memory. If the reqd. Data is not in the main memory a real disk operation is needed and an additional 75 ms are reqd. On the average. On the average 25% of the clients requests access the disk. During the disk I/O period the thread waits. Assume that there is no other process in system when the server is running. How many requests can the server handle per second if its a)single threaded b)multithreaded
1748A thread has to access the address space of all other threads in the same process and can therefore mess up the stacks of other threads. Why is this not a protection problem? Could the same be allowed to occur for processes, e.g. one process writing data into the stack of other.

1733hi, i am anjali. i m doing 3rd EIE in one of the top colleges affliated to anna university. i m really confused between whether to do ME or goto job , gain sum experience and then do MBA.all say that if v do ME , lecturer field is the only job oppurtunity that job oppurtunities in core companies for girls are very difficuilt and they r not well paid too..i dont want to go in teaching field. in my college too for campus only few core companies are coming and they too recruit only guys. but top software companies are comning for campus . other set say me to get placed in a software company in campus, gain experience & do MBA. pls help me by giving ur suggestions friends.
