Show students how the inside of a computer works

VR PC is a virtual computer resource that simulates a virtual p.c. Great for the classroom to vrpc_scr19sm.

VR PC is a virtual computer that simulates the main processes of a working PC. The virtual computer program is a great introduction to the inner workings of a computer. The 3D realistic parts of a virtual computers motherboard, sound card, AGP card, hard disk drive and cd/dvd drive are all simulated. Students can see what is going on inside a virtual computer. The computers main systems are simulated.
The motherboard can be rotated and moved, you can zoom in onto the motherboard to see simulations close up. VR PC is a powerful simulation of the main processes involved in running applications and using hardware on a Windows Personal Computer.

Great for use with computer science and computing curriculum.

VR PC simulates these events…

Mouse events

Simulates data travelling from the mouse port to the i/o controller then to south bridge. Data then travels to the north bridge and onto the CPU. From the CPU the mouse data is transferred back to the north bridge and into a memory location on the AGP card. When the data leaves the CPU it will update the graphics card with a new pointer position or menu opened etc.

Keyboard events

Simulates data travelling from the Keyboard port to the i/o controller then to south bridge. Data then travels to the north bridge and onto the CPU. From the CPU the Keyboard data is transferred back to the north bridge and into a memory location on the AGP card. When the data leaves the CPU it will update the graphics card with a new text cursor position etc.

Hard Disk events

(Read to Memory)  simulates data being read from the hard drive to memory. The arms on the hard disk move across the platters to read data from a specific location. Data is then transferred to the hard disk controller which sits under the platters. A ribbon cable (not shown) connects the controller to the IDE slot on the motherboard. Data moves through the IDE slot to the south bridge. . Data then travels to the north bridge and onto the CPU. Data is transferred to memory from the CPU.

(Write from Memory) simulates data being written onto the hard drive from memory. Data is read from memory into the CPU. Data leaves the CPU and travels to the north bridge. From here the data travels to the south bridge. Data is then routed to the IDE connectors. Data is received onto the disk controller and then transferred to the write heads on the arms of the hard disk. The arms on the hard disk move across the platters to write data to a specific location

CD/DVD Events

CD/DVD (Read to Memory) This simulates data being read from the CD. The laser is switched on to read data from a specific location. Data is then transferred to the CD controller which sits under the laser. A ribbon cable (not shown) connects the controller to the IDE slot on the motherboard. Data moves through the IDE slot to the south bridge. . Data then travels to the north bridge and onto the CPU. Data is transferred to memory from the CPU.

(Write from Memory) This simulates data being written onto the cd from memory. Data is read from memory into the CPU. Data leaves the CPU and travels to the north bridge. From here the data travels to the south bridge. Data is then routed to the IDE connectors. Data is received onto the disk controller and then converted into signals that fire a laser underneath the cd.

Sound Card Events

Sound Card (Microphone) Simulates analogue data from a microphone converted to digital data. Analogue data is inputted into the sound card through a socket. An analogue to digital converter (ADC) converts the signal into digital data. The sound card moves this data through the PCI connector onto the PCI bus. The data travels to the south bridge. Data then travels to the north bridge and onto the CPU.

Sound Card (Loudspeakers) Simulates digital data being converted into an analogue signal which is fed to the speaker sockets on the sound card. Data leaves the CPU to the north bridge and travels to the south bridge. Data is routed to the PCI bus. The PCI socket connects the sound card to the PCI bus. Data is transferred from the PCI bus to the sound card.
