Networking and Security
LIComputerfix will provide you with a FREE
ESTIMATE for any networking project or installation.

laptops, printers, hard drives, removable media like zip disks,

networks your computers and printers together using a technology
called Ethernet. This allows you to share a single internet
connection with all your computers without having to spend extra
money for another Internet Service Provider. This is especially
great for cable modem and DSL customers. We also make it possible
for you to share files, programs, and printers throughout your
home or business.
is a long-established networking standard, and ethernet equipment
is cheap and easily available. Ethernet does require running
new cabling to each computer you need to connect to the network.
Some other alternatives are available which use carry signals
using radio waves, power cables or phone lines within the home:
Wireless Ethernet (WiFi), HomeRF, and HomePNA. We don't particularly
recommend those standards for home networks - there are problems
with security, coverage, different standards, cost and availability
of equipment. A future guide will cover adding wireless Ethernet
to complement an existing network. Currently we think a standard
cabled ethernet network is the best solution for most people.

member of several communities. The residence hall network, the
campus network, and the global network. As such you have a social
responsibility (though one you can choose to not fullfill) to
protect the groups well being. A good reason for an intruder
to gain access to a res-hall machine is to use it as a launching
platform to attack other machines. It is very common for network
intruders to take control of sever machines like this and route
their traffic through them in order to make a trace back more
To set up
a home network you need to understand what function each piece
of equipment performs so you can connect them together correctly.
The jargon used can be confusing, but this glossary and diagram
describes the key equipment and what it does.
while these components are described and illustrated separately
for clarity, in practice you can often buy one box which combines
two or more functions (for example a router will often include
a built-in switch too).
those who believe that the security issues facing home users
are greatly exaggerated, and that the only entities which need
to be concerned about desktop and network security are businesses
which have critical data on their machines. And many think that
only broadband users or folks with high-speed connections need
to be concerned.
the vast majority of computer systems, including corporate ones,
are not compromised for the data they may contain. Rather, they
are often compromised for practice purposes, such as storage
space for warez, or to create remote zombies for large-scale
Distributed Denial of Service (DDoS) attacks against other networks.
Compromised systems today are even being used to send SPAM.
are not necessarily compromised by a dedicated cracker trying
a variety of remote commands until he/she successfully cracks
the system password. Instead, most attacks today are performed
using automated tools which attempt to exploit known vulnerabilities
in various OSes and applications.
If you are
experiencing computer problems and you are in need of repair,
we can send you a computer technician to help you with troubleshooting
your computer problem. We understand that new technology can
be confusing, and if you require help installing the latest
technologies onto your computer then we are your consultants.
