Most switches and routers these days allow for a standard straight through cable to connect each other. (So any CAT 5e or 6 cable you find at Best Buy will be fine)

Older devices (Such as a Cisco 2900xl switch) require a cross over cable to connect like devices such as a switch to switch. These cables can also be found at Best Buy and will be clearly labeled "Cross Over".

There are two different standards of straight through cables if making your own. See the related link.

To make a cross over cable, wire one end with the A standard and the other with the B standard.

There should be a little speaker icon in the lower right of you screen, next to the time. You can click this to get a sound adjustment bar. If you are having problems locating this, you can go to Start -> Control Panel, then click on Sounds, Speech, and Audio Devices. There should be an option there for "Adjust the system volume."

There were 3 methods of using ethernet. At this point only the hub with cat5 wiring is being used. The two older methods were a. use of a very thick coax cable with each station employing a tranceiver and a tap into the coax. and b. thinner coax cables with BNC connectors daisy chained from station to station. Called 10base2. So this is an obselete 10M ethernet network.

802.11n is rated for a maximum bandwidth of 135Mbps and Gigabit Ethernet (as the name implies) is rated for 1Gbps (or 1000Mbps).

You need Star Topology with peripherals A Server, Hub, Cable and other equipment likes PC, Printer, Scanner etc...

"Hub and spoke" is a term in air transportation to describe a common method for an airline to organize their flights. Airlines will have hubs in a few cities where most of their flights will originate, with spokes out to non-hub cities. Much like the hub and spokes of a bicycle tire. When flying from one city to another, you will typically have a connecting flight through one of the airline's hubs. This system can also be implemented with other forms of mass transit, and cargo transportation.

UDP is used for those applications that require speed, not quality of transmission. This would include streaming audio and video, and Voip. If you lose a packet or two it doesn't make a great deal of difference compared to file transfer protocol, where everything must arrive correctly.

Physical systems are tangible entities that may be static or dynamic in operation. For example, the physical parts of the computer center are the offices, desks, and chairs that facilitate operation of the computer. They can be seen and counted, they are static. In contrast, programmed computer is a dynamic system. Data, programs, output and application changes as the user's demand or the priority of the information requested changes.

Abstract systems are conceptual or nonphysical entities. They may be models-the abstract conceptualization of physical situations. A model is a representation of a real or a planned system. The use of models makes it easier for the analyst to visualize relationships in the system under study. The objective is to point out the significant element and the key interrelationships of a complex system.

That's known as "remote" technology, short for "TV remote control", as in "Where's the remote ?"

When you are using active scanning you have to send certain signal through network. This kind of attack the easiest to find, but the fastest to get information about a remote computer.

When you are using passive scanning, you are collecting information which are going through network without sending any request to a remote computer. This sort of attack really hard to find, but it's possible using special kinds of network packets. It requires more time then for the active mode.

You can have as many users you want on an enterprise network provided you have the ip address range for any number of applications. This can be unlimited if properly designed by using sub net addressing or by using a deferred addressing techniques. However care must be taken and follow strict designed rules otherwise there can be clash of addressing standards.

These are called protocols - a standard set of rules for common communications across networks.

No, frame delimiting is a primary responsibility of the Logical Link Control sublayer of the Data Link Layer..

Data link layer exists of 2 sublayers; Media Acces control Sublayer (MAC) & Logical Link Control sublayer (LLC)

It is more expensive and sophisticated as compared to a peer to peer network, can take more troubleshooting, and usually requires a dedicated network administrator which sufficient training to manage the network (comes down to cost).

Plus, the software to manage the network is more complex and can be more costly (in a non-open-systems area).

Yes you can. You can download programs that give you advanced features such as file sharing. However if you are running Windows, there is a built in tool that allows you to connect to a computer called Remote Assistance.

If the laptop has an Ethernet port (like a phone port, just bigger), connect the patch cable from it to the modem or router/switch/hub. If it does not have one, many manufacturers (Linksys, Belkin, D-Link are good) make USB or PC card ethernet adapters. Open Internet Explorer (other browsers will have different instructions). Choose Tools from the menu bar. Choose Internet Options. Choose the Connections tab. Click Setup. Make choices depending on your current method of connection (DSL or cable - different information needed for each). Call your ISP's Support line for more information.

A Wide Area Network is a connection between two or more network LAN segments that are a distance apart, usually too far apart to be connected as just 1 LAN. They may connect networks in different cities, countries, etc., over a wide distance.

Where are they found? All over the world, wherever the connections on a wide distance are required.
