Define SATA
Serial Advance Technology Attachment |
|
 |
|
| |
With the SATA interface, each drive has its own cable that connects directly to the Serial ATA host controller. There is no master-slave relationship between drives that use a Serial ATA interface (unlike Parallel ATA). There are no jumpers, terminators, or other settings on SATA drives for proper operation. |

DDR1 vs DDR2
(Double Data Rate RAM) |
 |
|
|
|
|
Memory Speed and overheating
There
are a number of upgrades that come with the new DDR2
technology over DDR1 memory. DDR2 memory is of course faster,
and will ultimately reach clock speeds of 667MHz or higher as
opposed to the top functional speed of DDR1 at 400MHz. The
higher speeds of DDR 2 memory allow it to have up to 10.6GB
per seconds of throughput - quite a bit more than DDR1 memory
which maxed at 6.4GB per second. The feature that makes these
higher speeds practical is the reduced power consumption of
DDR2, which runs at only 1.8 volts. Heat is one of the real
banes of IC's, and the faster you try and clock a chip the
hotter it runs and the less reliable it gets. One of the speed
limitations of DDR1 was that at 2.5 volts created too much
heat and was simply too hot to run consistently at speeds
greater than 400MHz. DDR2's 1.8 volts combined with a much
smaller (FBGA) chip package goes a long way towards solving
the heat issue at higher speeds.

Defference Between
AT and ATX |
|
There are two basic differences between old AT and newer ATX power supplies
The soft switch. On older AT power supplies, the Power-on switch wire from the front of the computer is connected directly to the power supply. On newer ATX power supplies, the switch goes to the motherboard, allowing other hardware or software to turn the system on or off.
