HOW TO CHANGE IP ADDRESS??
Hi fren, Here many of you are trying to change the ip address of your
now, heres the simple way to change the ip address. By using hotspot shield(hss).
This is the easy to to change the ip address just go to google search for hotspot sheild
and download it for free. You just need to install nothing more than that. :)

Data Destruction
Often an extension of unauthorized access, data destruction means more than
just intentionally or accidentally erasing or corrupting data. It’s easy to imagine
some evil hacker accessing your network and deleting all your important files,
but consider the case in which authorized users access certain data, but what
they do to that data goes beyond what they are authorized to do. A good example
is the person who legitimately accesses aMicrosoft Access product database
to modify product descriptions, only to discover he or she can change the prices
of the products, too.
This type of threat is particularly dangerous when users are not clearly informed
about the extent to which they are authorized to make changes.A fellow
tech once told me about a user who managed to mangle an important database
due to someone giving him incorrect access.When confronted, the user said, “If
I wasn’t allowed to change it, the system wouldn’t let me do it!”Many users believe
that systems are configured in a paternalistic way that wouldn’t allow them
to do anything inappropriate. As a result, users will often assume they’re authorized
to make any changes they believe are necessarywhenworking on a piece of
data they know they’re authorized to access.

PCI
Intel introduced the PCI bus architecture in the early 1990s, and
the PC expansion bus was never again the same. Intel made many smart moves
with PCI, not the least of which was releasing PCI to the public domain to make
it very attractive to manufacturers. PCI provided awider, faster,more flexible alternative
than any previous expansion bus. The exceptional technology of the
new bus, combined with the lack of a price tag, made manufacturers quickly
drop ISA and the other alternatives and adopt PCI.
PCI really shook up the PC world with its capabilities. The original PCI bus
was 32 bits wide and ran at 33 MHz, which was superb, but these features were
expected and not earth-shattering. The coolness of PCI came from its ability to
coexist with other expansion buses.When PCI first came out, you could buy a
motherboard with both PCI and ISA slots. This was important because it enabled
users to keep their old ISA cards and slowly migrate to PCI. Equally impressive
was that PCI devices were (and still are) self-configuring, a feature that
led to the industry standard that became known as Plug and Play (PnP). Finally,
PCI had a powerful burstmode feature that enabled very efficient data transfers.
AGP
Shortly after Intel invented PCI, the company presented a specialized, videoonly
version of PCI called the accelerated graphics port (AGP). An AGP slot is a
PCI expansion bus slots PCI slot, but one with a direct connection to the Northbridge. AGP slots are
only for video cards—don’t try to snap a sound card or modem into one.
. An AGP slot is almost universally brown in
color, making it easy to spot.
PCI-X
PCI-X, already available in systems such as the Macintosh G5, is a huge
enhancement to the current PCI technology that is also fully backwardcompatible,
in terms of both hardware and software. PCI-X is a 64-bit-wide bus
Its slots will accept regular PCI cards. The real bonus of
PCI-X is its much enhanced speed. The PCI-X 2.0 standard features four speed
grades (measured in MHz): PCI-X 66, PCI-X 133, PCI-X 266, and PCI-X 533.
Mini-PCI
PCI has even made it into laptops in the specialty Mini-PCI format . You’ll findMini-PCI in just about every laptop these days.Mini-PCI
is designed to use low power and to lie flat⎯both good features for a laptop
expansion slot.
PCI Express
PCI Express (PCIe) is the latest, fastest, and most popular expansion bus in use
today. As its name implies, PCI Express is still PCI, but it uses a point-to-point
serial connection instead of PCI’s shared parallel communication. Consider a
single 32-bit chunk of data moving from a device to the CPU. In PCI parallel
communication, 32 wires each carry 1 bit of that chunk of data. In serial communication,
only one wire carries those 32 bits. You’d think that 32 are better
than 1, correct?Well, first of all, PCIe doesn’t share the bus.A PCIe device has its
own direct connection (a point-to-point connection) to the Northbridge, so it
does not wait for other devices. Plus, when things start going really fast (think
gigabits per second), it’s difficult to get all 32 bits of data to go from one device
to another at the same time because some bits get there slightly faster than
others. That means you need some serious, high-speed checking of the data
when it arrives to verify that it’s all there and in good shape. Serial data doesn’t
have this problem, as all the bits arrive one after the other in a single stream.
When data is really moving fast, a single point-to-point serial connection is
faster than a shared, 32-wire parallel connection.
And is PCIe fast! A PCIe connection uses one wire for sending and one for
receiving. Each of these pairs of wires between a PCIe controller and a device is
called a lane. Each lane runs at 2.5 Gbps. Better yet, each point-to-point connection
can use 1, 2, 4, 8, 12, 16, or 32 lanes to achieve a maximum bandwidth
of 160 Gbps. The effective data rate drops a little bit because of the encoding
scheme—the way the data is broken down and reassembled—but full duplex
data throughput can go up to a whopping 12.8 GBps on a ×32 connection.
The most common PCIe slot is the 16-lane (×16) version most commonly
used for video cards The first versions of PCIe
motherboards used a combination of a single PCIe ×16 slot and a number of
standard PCI slots. (Remember that PCI is designed to work with other expansion
slots, even other types of PCI.)
Local Lingo
PCIe When you talk about the lanes, such as ×1 or ×8, say “by” rather
than “ex” for the multiplication mark. So “by 1” and “by 8” are the correct
pronunciations. You’ll probably hear it referred to as “ex 8” and “8 ex”
for the next few years until the technology has become a household term.
The bandwidth generated by a ×16 slot is far more than anything other than
a video card would need, so most PCIe motherboards also contain slots with
fewer lanes. Currently ×1 and ×4 are the most common general-
purpose PCIe slots, but PCIe is still pretty new so expect things to change
as PCIe matures.
Touch Screens
A touch screen is a monitor with some type of sensing device across its face that
detects the location and duration of contact, usually by a finger or stylus. All
touch screens then supply this contact information to the PC as though it were a
click event from a mouse. Touch screens are used in situations for which conventional
mouse/keyboard input is either impossible or impractical.Here are a
few places you’ll see touch screens at work:
• Information kiosks
• PDAs
• Point-of-sale systems
• Tablet PCs
Touch screens can be separated into two groups: built-in screens like those in
PDAs, and stand-alone touch screen monitors like those used in many pointof-
sale systems. From a technician’s standpoint, you can think of a stand-alone
touch screen as amonitor with a built-in mouse.All touch screens will have a separate
USB or PS/2 port for the “mouse” part of the device, along with drivers that
you install just as you would for any USB mouse.
