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.

Teach how a hard disk drive works

Visual Hard Drive simulates the operation of a computer’s hard disk drive and shows how a hard drive works. The virtual drive has a controller board, four magnetic platters and eight read/write heads. Up to 32 bits of data can be written and read from the hard disk drive. The drive simulates data being written and read from the top platter and shows how a hard drive works.vishd5
Virtual data can be written in a safe environment. Data can be read from the virtual disk and be displayed as binary, bytes and ASCII.

Visual Hard Drive has four magnetic platters and eight read/write heads.

Data limits
Our hard drive is fixed to write at sector 1 from here we can write 32 bits of data. In total 32 bits of data can be written to the disk.
The program simulates data being written to sector 1. The start address is 0000000200 Addresses are offset from this start address.
Write to disk

Every part of the platter has its own unique capability to store a binary 0 or binary 1 when writing to the platter the magnetic surface will contain either 0 or 1. In our simulation a red dot signifies a 0 a gap signifies a binary 1. As the disk is spinning all the time a circular data trail is left.
Visual Hard Drive shows how a hard drive works.

 

Teach how CD drives work

Students can practice writing data to a virtual 3D disk the program shows the laser firing and a pit created in the disk.

vis_cd_scrVisual Disk simulates the operation of a CD/DVD Rom drive the simulation enables virtual disks to be created.

Shows how cds work.
A CD-R type disk is used in simulations.
The laser is shown writing data to the CD-R disk. Virtual disks can be created in a safe environment. Data can be read of the virtual disk and be displayed as binary, bytes and ASCII.In the main window is a virtual CD/DVD drive this contains a light blue CD-R disk. The CD Rom drive sits on a PCB this contains circuits that control the operation of reading and writing data from a disk. A motor spins the CD. As the disk spins the laser fires and reads data or writes data to the disk and shows how cds work.

When writing to a disk a laser beam is visible between the laser and the disk. When the laser makes contact with the disk a pit is created in the disk this signifies a binary 0. If the laser does not fire the disk is left untouched, creating a land section, this signifies a binary 1. The disk simulation shows each individual bit of data and shows how cds work.

Data limits

Our CD-ROM drive is fixed to write at sector 270 from here we can write 32 bits of data. In total 32 bits of data can be written to the disk. The program simulates data being written to sector 270.

The start address is 00087000 Addresses are offset from this start address.

Every part of the disk has its own unique capability to store a binary 0 or binary 1 when writing to the disk the laser is fired to make a pit in the disk this pit signifies a binary 0. If the laser does not fire a land section is created this signifies a binary 1. Because the disk is spinning all the time a circular data trail is left.

In the main window the CD-R disk will spin. The laser will fire and produce a pit if the data is set to 0. If the data is set to 1 the laser will not fire and will leave a land section on the disk. Depending on which boxes you have set to 0 or 1 a trail of lands or pits will appear on the surface of the CD-R. The program writes data beginning at address 00087000 and finishes writing at 00087003.
