The traditional way of allocating a single channel among multiple competing users is to chop up its ( ) by using one of the multiplexing schemes such as FDM (Frequency Division Multiplexing). If there are N users, the bandwidth is divided into N equal-sized portions, with each user being assigned one portion. Since each user has a private frequency ( ), there is no interference among users.When there is only a small and constant number of users, each of which has a steady stream or a heavy load of ( 本 题 ), this division is a simple and efficient allocation mechanism. A wireless example is FM radio stations. Each station gets a portion of the FM band and uses it most of the time to broadcast its signal.However, when the number of senders is large and varying or the traffic is ( ), FDM presents some problems. If the spectrum is cut up into N regions while fewer than N users are currently interested in communicating, a large piece of valuable spectrum will be wasted. If more than N users want to communicate, some of them will be denied ( ) for lack of bandwidth.?A. traffic B. dateC. burstyD. flow

Identify three reasons that explain why assigning more than one managed serve achieve better performance than running one managed server with more resources?()A、Thread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources.B、Current CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance.C、By a combination of prioritization of processes on the OS level and Work Manager in WLS, one could tune the whole environment more precisely.D、Assigning more than one managed server to hardware will never bring better performance. E、More instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers. F、Depending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.
