What is eSATA??

External Serial Advanced Technology Attachment or eSATA is an external interface for SATA technologies. It competes with FireWire 400 and universal serial bus (USB) 2.0 to provide fast data transfer speeds for external storage devices.

SATA replaced ATA legacy technology as the next generation internal bus interface for hard drives. The SATA interface is more streamlined than ATA and provides serial architecture for greater speed than the older parallel technology. eSATA cables are narrow and can be up to 6.56 feet (2 meters) in length, whereas parallel cables are much wider and limited to a length of 18 inches (45.7 cm). With eSATA, the speed of SATA expands to encompass exterior storage solutions.

While eSATA reaches transfer rates of at least triple those of USB 2.0 and FireWire 400, it does have one drawback. eSATA requires its own power connector, unlike the aforementioned interfaces. It is still an excellent choice for external disk storage, however. Unlike USB and FireWire interfaces, eSATA does not have to translate data between the interface and the computer. This enhances data transfer speeds, while saving computer processor resources and eliminating the need for an extra off-load chip.

CAT6 Cable??

Even though modern home networks are connected using wireless technology, there are cases when you will still need to use LAN cables. When a wireless signal can’t reach a portion of a house or an office, cables might be your only option.

You’ll encounter several cable type designators with names like CAT5, CAT5e, and CAT6. CAT5 cable is the minimum required for the current Internet standards. CAT5e cable is a higher grade version of CAT5, and CAT6 cable is commonly used for Gigabit Ethernet, an up-and-coming version of Ethernet that operates at 10 times the speed of Fast Ethernet. CAT6 cable costs more than CAT5e but is worth the extra money if you want to future-proof your cable installation.

Intel Huron River CPUs coming Q1 2011 with integrated WiMAX

Early details of Intel’s next-generation mobile processor platform, codenamed Huron River, have emerged well ahead of its expected launch in Q1 2011. Huron River will be based around the 32nm Sandy Bridge process silicon, and be made up of dual- and quad-core processors supporting Intel Turbo Boost.

In addition to the main cores, the Huron River chips will integrate various forms of wireless connectivity too. Bluetooth is one such technology, as well as WiFi and even WiMAX on certain models. There’ll also be support for Intel’s wireless display technology, too.
Intel are expected to position Huron River processors as suitable for both regular laptops and ultrathin models. It will replace the Calpella platform, first launched in 2009, as the seventh-generation Centrino.
