Many Schools use our How a Computer Works package.
In response to Teachers comments we have made available separately an enhanced version of the Virtual Computer application included with How a Computer Works.




 
Computer science software

Great for use with computer science and computing curriculum.

The Mouse Simulation shows either an external view or internal view of the mouse, the circuit board is shown transferring data as the mouse is moved. The mouse has control over a pointer on the virtual desktop. Useful to show how a mouse works.

Desktop The virtual desktop is based on Windows, clicking on the various desktop items opens application windows. The Word Processor application opens and allows words to be typed in using the Virtual Computers keyboard, as letters are typed in, the keyboards membrane lights up to show the data flow of the key being pressed. The motherboard is shown simulating the flow of data between the various chips. The Bitmap Editor allows dots to be drawn using the mouse. This shows how software works.



 

Motherboard is based on a Intel Pentium processor. The board includes all the chips that would be found on a basic PC. Data flow is simulated between all the main chips. The main processes of the motherboard are simulated. Individual simulations of the motherboard processes are available separately, these simulate data transfer between the CPU and Memory showing data flow between the North Bridge hub. Data is simulated between the CPU and Serial port. The IDE interface is simulated to the CPU. CPU to AGP slot (Graphics card). CPU to PCI slots. Mouse and Keyboard port simulated to CPU through LPC controller, South bridge and North bridge. Shows how a motherboard works.

Memory Card Simulates a Memory card with option of including operation with Motherboard simulations, so works when CPU reads/writes to memory.

AGP Graphics Card
Simulates the operation of the Graphics card including on board memory, this simulation can optionally be included with the Motherboard simulations when the CPU updates the screen memory.

Hard Disk Simulates data being read from a IDE hard drive. Data is read from the hard drive and simulated through the South bridge to the North bridge into the CPU.

Floppy Disk Drive Simulates data being read from a IDE floppy disk drive. Data is read from the hard drive and simulated through the South bridge to the North bridge into the CPU. Simulates a disk being inserted into the system tower and read in the disk drive.

CD-ROM/DVD Drives Simulates a CD-ROM and DVD Drive. Both simulations feature side and top views of the disk being read. The system tower simulates a disk being inserted in the drive, has the option of using a transparent disk enabling the viewing of the laser and collector underneath. The side view simulates the laser working and reading data from the disk. Data is transferred from the drive to the IDE interface on the motherboard (in the South bridge) data is shown travelling to the North bridge into the CPU.

CPU Simulates the internal operation of a Pentium CPU. The block simulation can optionally be incorporated into motherboard simulations. Shows how a pentium works.

Cable Modem Simulates the operation of a Broadband connection, simulates the retrieval of a web page which is displayed in the virtual desktops web browser. The cable modem is connected to a PCI slot on the motherboard, data is simulated travelling between the Modem, PCI slot, North bridge and CPU.

Sound Card Simulates a sound card, loudspeakers and keyboard. Clicking on the keyboard produces a sound. The data from this travels through the Sound Card and onto the motherboard through the PCI slot to the North bridge into the CPU. Sound is reproduced through the loudspeakers and simulated through the sound chip on the PCI Sound card. Shows how a sound card works.

SCSI Card and Hard Disk drive Simulates the operation of a SCSI card and external SCSI hard disk drive. Data is read from the hard disk and transferred to the SCSI card. The card connects to the PCI slot on the motherboard, data is transferred through the PCI bus to the North bridge into the CPU.

Scanner Simulates a document being scanned. The scanner is connected to the Motherboard through a USB interface, data is read into the LPC controller and into the South Bridge and North Bridge before being processed by the CPU. data is then transferred to the AGP Graphics card where the document is rendered on the virtual desktop. Shows how a scanner works.

Digital Camera Simulates a digital picture stored in the Cameras memory being downloaded and displayed by the computer. The Camera is connected to the Motherboard through a USB interface, data is read into the LPC controller and into the South Bridge and North Bridge before being processed by the CPU. Data is then transferred to the AGP Graphics card where the picture is rendered on the virtual desktop.

Virtual System

System Tower includes a CD ROM, DVD Drive and Floppy Disk Drive these are fully functional and allow disks to be put into drives.

Inside the Computer is a program of screens with labelled images of the main computer parts. This program is included with Virtual Computer +
