Matrix as Metaphysics

 
The Matrix presents a version of an old philosophical fable: the brain in a vat. A
disembodied brain is floating in a vat, inside a scientist's laboratory. The scientist has
arranged that the brain will be stimulated with the same sort of inputs that a normal
embodied brain receives. To do this, the brain is connected to a giant computer simulation
of a world. The simulation determines which inputs the brain receives. When the brain
produces outputs, these are fed back into the simulation. The internal state of the brain is
just like that of a normal brain, despite the fact that it lacks a body. From the brain's point
of view, things seem very much as they seem to you and m
The brain is massively deluded, it seems. It has
all sorts of false beliefs about the world. It
believes that it has a body, but it has no body. It
believes that it is walking outside in the sunlight,
but in fact it is inside a dark lab. It believes it is
one place, when in fact it may be somewhere
quite different. Perhaps it thinks it is in Tucson,
when it is actually in Australia, or even in outer
space.
Neo's situation at the beginning of The Matrix is
something like this. He thinks that he lives in a city, he thinks that he has hair, he thinks it
is 1999, and he thinks that it is sunny outside. In reality, he is floating in space, he has no
hair, the year is around 2199, and the world has been darkened by war. There are a few
small differences from the vat scenario above: Neo's brain is located in a body, and the
computer simulation is controlled by machines rather than by a scientist. But the essential
details are much the same. In effect, Neo is a brain in a vat.

Network technology

Data signals are transmitted from one device to another using one or more types of
transmission media, including twisted-pair cable, coaxial cable and fibre-optic cable. A
message to be transmitted is the basic unit of network communications. A message may
consist of one or more cells, frames or packets which are the elemental units for network
communications. Networking technology includes everything from local area networks
(LANs) in a limited geographic area such as a single building, department or campus to
wide area networks (WANs) over large geographical areas that may comprise a country,
a continent or even the whole world.

internet securitiy

In 1985, RFC 950 defined a standard procedure to support the subnetting, or division, of
a single Class A, B, or C network number into smaller pieces. Subnetting was
introduced to overcome some of the problems that parts of the Internet were beginning
to experience with the classful two-level addressing hierarchy:
- Internet routing tables were beginning to grow.
- Local administrators had to request another network number from the Internet
before a new network could be installed at their site.
Both of these problems were attacked by adding another level of hierarchy to the IP
addressing structure. Instead of the classful two-level hierarchy, subnetting supports a
three-level hierarchy. Figure 6 illustrates the basic idea
