Now I would like to know a few things about the specs. First off all what does this mene:

Level 1 (L1) cache
8 KB

Level 2 (L2) cache
128-KB or 512-KB (depending on your computer configuration) pipelined-burst, eight-way set associative, write-back SRAM


What is a cache?

Second of all what does it mean when it says "333- and 400-MHz DDR SDRAM"? I know thats the speed of the memory but I am looking for a more detailed answer. Is that the maximum speed infromation can be transfered into and outof the memory chipset(s)?

Also it says

Expansion Bus

Bus type
PCI

Bus speed
33 MHz


What does that mean? I know what the expantion buss is but what is buss speed? Is that the maximum speed any device in the busses in the back can run at? And is the USB buss they are talking about ot the expantion bays?

Computer bus

From Wikipedia, the free encyclopedia


Jump to: navigation, search
In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers and typically is controlled by device driver software. Unlike a point-to-point connection, a bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together.
Early computer buses were literally parallel electrical buses with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallel electrical bus. Modern computer buses can use both parallel and bit-serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB. http://en.wikipedia.org/wiki/Computer_bus

The expansion bus applies to the pci slot at the rear of an atx case. Those are used for sound cards, older types of video cards, and other devices like tv tuner and video capture cards. The usb buss is something totally different for various reasons. One is the lower voltages it provides for input and input/output devices like a usb mouse or keyboard, printers, digital cameras, etc..
