In _______ the virtual machine simulates hardware, so it can be independent of the underlying system hardware.
In a press there are three types of printing machines A, B, and C. Machine A can print ten thousand pages in 8 hours, machine B can do the same task in 10 hours, and machine C can do the same task in 12 hours. All three machines start the task at 9∶00 a.m. Machine A breaks down at 11∶00 a.m. and machines B and C continue working. At 12∶00 noon machine B also breaks down and machine C alone has to complete the remaining task. What is the approximate time of completion of the task?
Suppose we want to design a synchronous circuit that processes a string of 0’s and 1’s. Given a string, it produces another string by replacing the first 1 in any subsequence of consecutive 1’s by a 0. Consider the following example. Input sequence: 00100011000011100 Output sequence: 00000001000001100 A Mealy Machine is a state machine where both the next state and the output are functions of the present state and the current input. The above mentioned circuit can be designed as a two-state Mealy machine. The states in the Mealy machine can be represented using Boolean values 0 and 1. We denote the current state, the next state, the next incoming bit, and the output bit of the Mealy machine by the variables s, t, b and y respectively. Assume the initial state of the Mealy machine is 0. What are the Boolean expressions corresponding to t and y in terms of s and b ?
The following sentences form a paragraph. The sentences P,Q,R and S are not ordered properly.Choose the option that arranges these sentences in the proper order. P.  A person using virtual reality equipment is able to "look around" the artificial world, move around in it, and interact with virtual features or items. Q. Their aim is to simulate a user's physical presence in a virtual or imaginary environment.  R. Current VR technology most commonly uses virtual reality headsets or multi-projected environment.  S. They use sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations.
