Build a virtual computer

Building a computer system in a computer science lesson may be in practical for a classroom of students.
Computer Builder lets pupils build a virtual computer and integrate the system tower into a complete computer system. cbuild4
Great for use with computer science and computing curriculum to build a virtual computer.
Shows students how to build a computer.
Motherboard The first part of the building process starts with the assembly of the computers Motherboard. The Motherboard is placed into the system tower. A graphics card is placed onto the motherboards AGP slot. The next step involves placing the Memory cards into the connectors on the Motherboard. After this is completed the Sound and MIDI card is placed into a PCI slot. Further expansion cards maybe used in the PCI slots. These are a SCSI card that works in conjunction with an external hard disk drive. A PCI Modem card that works with a broadband connection.

Hard Disk The next stage is to populate the tower with disk drives. The hard disk is placed in the system frame tower. As the drive is placed in the tower the blanking plate is removed from the front panel. The floppy disk drive is inserted followed by the CD-ROM and DVD drives.

PSU At this point the Power Supply Unit is placed into the tower. The last job is to place the cover over the side of the tower.The system tower is now complete.

Computer Table Once the tower is built it can be incorporated into a system. A computer table is populated with the computer system. The tower is placed on or around the table the monitor is placed on the top shelf for easy viewing.

Keyboard The system is now built up with further peripherals, a keyboard and mouse are added. Loudspeakers, Scanner, Printer and external SCSI hard Disk drive can be added.

Connections Once the system table is populated the task of connecting the peripherals to the system tower can begin. The back of the virtual computer represents that of a typical computer tower.cbuild7

Start Up Once the tower is wired up the system can be powered up, this simulates the start up procedure of a Windows XP based machine.

Computer Builder will prove invaluable to teaching students the basic parts of a computer and the assembly of one in a safe virtual environment.

Virtual network simulation…

Networks are an important part of the computer science curriculum… VR Network simulates the operation of a virtual network enabling students to understand how a local area network (LAN) works. All of this can be achieved in a virtual environment.

vrnwscr2VR Network simulates the key processes in a typical network environment. The virtual computers simulate two workstations, administrator, server with RAID drives, network switch, modem and printer.

This software is great for learning how a network works.

As  key processes are simulated and data flows between chips on the computers motherboard, data lines light up to signify data travelling through different parts of the network. Hard disk arms move when data is read/write.

3D graphics show the network components in amazing detail.

The network consists of two computers labelled 1 and 2 running windows. These two machines are typical of what you would find on a windows network.

The Motherboard is based one found in a PC with where support for a Network is built into the Motherboard. Great for use with computer science and computing curriculum to show how a network works.

The administrators computer  is similar but includes a CD-ROM drive for loading software onto the server. The administrators computer has extra network privileges to enable specific tasks to be carried out.

The server features two CPU’s and two memory banks.  A RAID hard disk system is simulated in the server.

The network switch has 8 LAN connectors and all virtual computers network drive, modem and printer are connected.

The network drive is used for backing up data from the server and other networked computers.

The ADSL modem simulates an internet connection all network computers use the modem to access the internet.

A network printer  simulates printing from a networked computer.

A number of simulations demonstrate key network operations.

Virtual Computer

A virtual computer is useful addition to any schools computer science department.
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.
Great for use with computer science and computing curriculum. vc+scr
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.
