Hard disk


A hard disk is really a set of stacked "disks," each of which, like phonograph records, Hard disks have diffrent sectors shares data recorded electromagnetically in concentric circles or "tracks" on the disk. A "head" (something like a phonograph arm but in a relatively fixed position) records (writes) or reads the information on the tracks. Two heads, one on each side of a disk, read or write the data as the disk spins. Each read or write operation requires that data be located, which is an operation called a "seek."

New DVD+RW


Imagine being able to record 4 hours instead of 2 hours of the highest quality DVD video on a disc. Or to store 8.5 gigabytes, Equaling about 12 fully recorded CD-Rs, instead of 4.7 gigabytes, on a single sided DVD.
All this is possible, here and now, with the advent of DVD+R Double Layer recording technology. Based on the proven double layer technology that has been used in DVD-Video for many years, DVD+R DL almost doubles the recording capacity when compared to traditional DVD recording media. And because the disc is single sided, there’s no need to flip it over halfway through playback or recording.

DDR Ram


DDR RAM is Double Data Rate RAM.
Although DDR RAM can be designed for various clock rates, we will concentrate on DDR-266 RAM. It operates with a 133 MHz clock, but it uses both the leading and trailing edge of the clock cycle. Hence, it produces data at an equivalent clock rate of 266 MHz, which is a double data rate.
DDR RAM achieves its double data rate even though the internal RAM core operates at only the 133 MHz clock rate. Effectively, if a DDR RAM chip produces 8 data bits for every cycle of the 266 MHz clock, then it is internally producing 16 data bits for every cycle of the 133 MHz clock, but delivering on demand only 8 bits at a time to the I/O data pins. This is we can say a advance form.Dual channel DDR is also available in coating we can say.And flash DDR is also ready for use

Light wieght laptops


Experience optimum mobility with an ultra compact 10.1" design,
weighing just 1.23Kg (with a 4 cell battery),
so you can carry less,but do more.Despite being one of the lightest in its class and small enough to carry in a handbag, briefcase or luggage, it still incorporates comprehensive functionality for maximum performance on the move.

Intel(R)-PCI-Bridges


Intel offers both transparent and non-transparent PCI bridges, As well as a PCI-X transparent bridge with opaque memory mode for semi-transparent operation. Both product lines allow designers to add more PCI/PCI-X devices or more PCI/PCI-X option card slots than a single PCI bus can support.
However, non-transparent bridges differ from standard, transparent PCI-to-PCI bridges by allowing independent mapping of primary and secondary bus address spaces, a key benefit when local devices require private memory maps.

Raid innovation


Intel leads the storage world with innovative RAID technologies that provide critical data protection.
Discover how hardware and software RAID combine into one phenomenal solution.

Modern age laptops


In the modern age, laptops or notebooks have become an essential tool in our daily life,
so much so that you can see out of 10 urbanites,
7 of them will be carrying laptops.
Either for work or leisure, laptops have become part of the human accessories, much like watches and mobile phones.
As with other accessories, they must look fashionable and trendy for the wearer, which in this case, the laptop owners.
