1. Motherboards and CPUs Introduction to Computer Applications Reference: graphics and models are taken from web sources.

2. Speed – the more we get, the more we want

3. Interfaces hold it all together

4. An interface connects two hardware devices. An interface can consist of controllers with built-in software, cables, etc.

5. An example of Interface

6. Data Exchange on motherboard

7. Motherboard – a hub of all data exchange

9. Power Supply

10. Sockets

11. Connectors

12. Another connector!

13. Some more connectors…

15. Pentium 4 Socket

16. Finding out CPU?

17. On startup screen…

18. A powerful fan!

19. Caches Ram is slower [533 or 677Mhz as compared to CPU] L1, L2, and L3 caches are used. CPU typically is only utilizing 35% of clock ticks. remedy against “bottleneck”. Latency!!!

20. Caches orientation

21. Several types of I/O bus The ISA bus – an old, low-speed bus which is not used much any more. The MCI, EISA and VL buses – faster buses which are also not used any more. The PCI bus – a general I/O bus used in more modern PC’s. The PCI Express – the most modern bus.

22. FireWire: i-Link IEEE 1394

24. USB The USB cable can also supply power to the devices. Up to 127 USB devices can be connected to the PC using USB hubs. USB devices can be connected ”On the fly”, without restarting the PC.

25. Some uses… Card reader for CF and other RAM cards Trackballs and Wacom drawing pen (tablet). Flatbed scanners and ISDN-modems. Newer printers. A color laser printer is faster using the USB 2.0 interface than the old LPT- interface. External CD- and DVD-drives. External hard disks. USB-based speaker or microphone systems. Interface to digital cameras and MiniDisc.
