Computer Networking

A destructive program that masquerades as a benign application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. One of the most insidious types of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer. If your system is attacked by the same please install the new Norton anti Virus 2008 or Norton Internet Security 2008

False.

A domain can be redirected via the .htaccess file or other means, but can only be registered to one IP address.

An IP Address can, however, have multiple aliases... so, for example,

earth.com can have an alias, say, greenearth.com and both can point to the same IP address and site.

NNTP

Wireless transfer uses radio signals and is always slower than wired transfer.
When you use cable, the application (say a router) has the entire cable to itself - other applications (say a stereo) will use a different cable, and the signals in different cables do not interfere with each other.
When sending through air, the application must share the air space with radio, television, cell phones, other wireless routers (where I live there is about a dozen WiFi networks within range) and electronic noise from fridges, microwave ovens and whatnot.

The net effect is that a wireless transmission can only use a tiny slice of the radio spectrum to avoid collision with everything else that is also using radio waves.
A cable transmission, on the other hand, can use almost the entire spectrum without worrying about collision with signals in other cables.

So cable transmissions will always have an edge in bandwidth: Whatever scheme is invented to stuff more data into less wireless spectrum could equally well be used for cable transmissions, and cable has more available spectrum to begin with.

Ethernet cable being shielded or unshielded twisted pair or CAT 5.

A DMZ allows external customer access to designated internal resources.

The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external attacker only has access to equipment in the DMZ, rather than any other part of the network. The name is derived from the term "demilitarized zone", an area between nation states in which military action is not permitted.

Take a Category 5 Ethernet cable (Cat-5) or better (Cat-5e or Cat-6), plug it into the "input" port (usually marked "computer," "network," or some similar name), and plug the other end of the cable into the Ethernet port on the computer. Some devices may have Wi-Fi, in which case you can connect using the SSID and security key usually located on the back or bottom of the modem.

MAC/PC/printer to router. Router to modem. Modem to wall/internet. Wired or wireless router is optional, same principle.

Network+ Guide to Networks answer: 802.11n

click -start

click run

type cmd

type ipconfig/all

it will display all the details of all the lan cards and their MAC adddress

as Physical Address. . . . . . . . .

yes but they dont want to

The localhost address is designed to verify that the software for networking has been installed and is operating correctly. It does not pass any packets to the network.

The advantage of science is that we can keep evolve and find new ideas. Make new technology ( advanced, easier, and safer), medicines( live longer). One disadvantage of science is that science ruins the christian or the bible's world. Science tries to brainwash you that Jesus and God doesn't exist by the theory of evolution. Advantage of technology is that we can do stuffs quicker, easier, safer, and have more leisure time. the disadvantage is that technology ruins earth like taking natural's resources to make these technology like plastic, oil, and iron ,and these technology end up harming the planet. Even the people ruins the planet by using technology. We try to recycle ,but that is not going to help because the air is getting worse each year and one day the temperatures will rise and end up killing humanity. Everything has disadvantage and advantage ,but without this i wound't be writing you this or even speak. we human's curiosity left us where we are ,but we need to make better choices as the time goes

In networking, PDU means "protocol data unit", and it is the generic name of the "packets" of data used at different levels of the network. Using the numbering of the OSI layers:

At layer 2, the PDUs are called "frame". Example: An Ethernet frame, a frame-relay frame.

At layer 3, the PDUs are called "packets". Example: An IP packet.

At layer 4, the PDUs are called "segments". Example: A TCP segment, a UDP segment.

If you have Vista, you click on the network icon on thestart bar and click add network or something like that.

The Duplex theory provides an explanation for the ability of humans to localise sounds by time differences between the sounds reaching each ear (ITDs) and differences in sound level entering the ears (interaural level differences, ILDs).

The duplex theory states that ITDs are used to localise low frequency sounds, in particular, while ILDs are used in the localisation of high frequency sound inputs.

In both cases, the site must keep a database record for the user. With HTTP authentication, the user first registers with the site. During each subsequent visit, the user provides a username and password, which allows the site to identify the user and update the user's record. With cookies, the user does not explicitly provide a username and password. However, browser identifies the user by sending the user's cookie number each time the user accesses the site.

• HUB usually in this case describes that ie. a parcel has arrived at a "National Sortation Centre" (aka. the destinated mail office).
• HUB SCAN thus, usually refers to the NSC has received the consignment (ie. has received the parcel).
