Installed more RAM on your
older computer but it's not going faster?
Unfortunately, the ability of Windows to use RAM does not always coincide
with ability of a motherboard's chipset to cache RAM, so be sure to check
your motherboard's manual before you upgrade. The motherboard's chipset
determines how much RAM can be cached. If the motherboard has an elderly
chipset, the amount of RAM it can cache might be limited to as little
as 64MB.
If a motherboard can only cache 64MB of RAM, such as one with the elderly
Intel TX chipset, and you install 128MB, even if it works, it will slow
the system down significantly, because the excess RAM cannot be cached,
and so will be accessed in the same relatively slow manner as the virtual
memory swap file that Windows sets up on the hard disk drive is accessed.
RAIDIT!
Redundant Array of Independent Disks (RAID)
While RAID-0 is known as data striping, RAID-1 is known as data mirroring.
In RAID-1, data being written on one hard disk is simultaneously copied
to another hard disk. RAID levels range from 0 through 5. There is one
another level of RAID known as RAID 10, which is a combination of RAID
1 and RAID 0, and it is the best in terms of performance and redundancy.
IRQ clash
When there is an IRQ conflict, you should try reassigning IRQs in the
BIOS manually or try the card in a different PCI slot. By providing a
device with a free IRQ, the problem will be solved. To know about IRQ
assignments on your machine, try Start » Accessories » System
tools » System Information; click on Hardware Resources.
LCD vs Plasma
Tell your clients the difference straight-faced. You don't have to tell
them you read it here
Charles Babbage (1792 - 1871). In 1834, he designed
the Analytical Engine, the precursor of the computer. He was unable
to obtain funding for it from the government, who thought it would
be worthless.
The first computer was launched in 1943, more than 100 years after
the Babbage design. In 1998, the Science Museum in London, UK, built
a working replica of the Babbage machine, using the materials and
work methods available at Babbage's time. It worked just as Babbage
had intended.
Anudder geek:
Kees
(Kornelis) Antonie Schouhamer Immink invented an efficient technique
to improve playing time and disc playability. His techniques have
found widespread application in CD, DVD, and Blu-Ray Disc systems.
His research resulted in around 1000 patents.
Ultimate geek:
Heron of Greece invented steam power in 50 BC. But
the leaders of the day thought that it would cause unemployment
which may lead to unrest and the invention ran out of steam. The
steam engine reappeared again only in 1698.
Nottageek!
In 1899 the director of the US patent Office assured
President McKinley that "everything that can be invented has already
been invented." Nou ja, toe nou!
