No. But the copies of the same program can be executed on the same time on more than one computers.

Why do modern machines consist of multiple levels of virtual machines?
Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture
Why you need interrupt?
An interrupt is a signal from a device attached to a computer or from a program within the computer that causes the CPU to stop executing the current program and figure out what to do next. It enable input/output device communicate or get the attention of the processor, and execute a program that need more attention.
Why were machine guns more destructive than single shot guns?
They are not- but they have a higher chance of hitting their target.
What is a single license?
A single license is a type of copyright that restricts the use of the program to one computer, or one server. this means that the program cannot be installed for free on different computers. single license is used for more important programs like Microsoft office and Macromedia software.
What is example of fetch and execute cycle?
When a typical microcomputer has finished executing a program control is transferred to another program which flashes the cursor on the screen and checks the keyboard if any keys were pressed In some processors an insruction may take up more than one storage location
What is source code c?
"Source code", in a programming language, refers to the original program, as written by a programmer (and more or less readable by humans); the version of the program before it is converted into machine language by the compiler.
Describe how you could obtain a statistical profile of the amount of time spent by a program executing different sections of its code?
One could issue periodic timer interrupts and monitor what instructions or what sections of code are currently executing when the interrupts are delivered. A statistical profile of which pieces of code were active should be consistent with the time spent by the program in different sections of its code. Once such a statistical profile has been obtained, the programmer could optimize those sections of code that are consuming more of the CPU resources.
If machine A performs work in twice as much time as machine B then machine B will use more what than machine A?
Machine B will use more power.
What is the meaning of programmer in c language?
PROGRAMMERThe person who both designs/writes the program code is called: The programmer.PROGRAMMING LANGUAGEThe program code itself is called: The programming language.INTERPRETER/COMPILERMost programming languages use 'high level' english based commands...but computers only know how to read 'low level' machine code numbers, instead.This means that in order for such programming languages to work; then, there needs to be some form of intermediary translation program; which can translate from 'high level' english down to 'low level' machine code numbers.Programming languages are either:interpreted(translates just 'one' single line of code at a time into machine code language/such programming languages tend to run more slowly...as every single line needs to be 'interpreted', first)compiled(translates 'all' of the program code lines into machine code language/complied code runs extremely fast because it doesn't need any further translating)QBASIC, is an interpreted programming language.C/C++, are both compiled programming languages
A given source statement may be converted to any number of machine level instruction?
Yes. A single high-level statement can generate one or more machine code instructions, sometimes in the order of several dozen instructions.
The more memory your computer has the faster it goes?
Generally speaking, yes. However, the main strength of more RAM is that your computer is faster at multitasking but running a single program will also be faster.
Why technology management is important?
why technology management is relevant and is becoming more important when executing a big project
