Report Task 2
~ Hardware and Software Used ~
To create the new Top Toggs information system I have used a computer of the following specification:
Internal:
Intel Pentium Celeron CPU running at 566Mhz.
128Mb of RAM
8GB UDMA66 Hardisk
52x CD-ROM Drive
1.44Mb Floppy Disk Drive
Onboard 128 Bit Sound
Onboard 4Mb Graphics
10/100 Ethernet Network Card
External:
Standard 15” CRT Monitor
Standard Windows 101 Key Keyboard
Standard two-button mouse
LaserJet printer (accessed via Network)
The keyboard, as the name may suggest, is a simple PCB that is sensitive to touch. The plastic casing incorporates 101 or 101 keys that are supported directly above the areas of the PCB that responds to touch. Therefore when a key is pressed it triggers an electronic signal that the computer interprets as a binary number, which is in turn changed into the appropriate character.
