Computer Networking

A network delay of 84ms specifies the time it takes for a data bit to travel across the network

IP addresses, DNS database, Name Servers, and the Domain Name Space.

Ketera Network offers their clients e-commerce apps to help with the purchasing a product or service. They partner with and help distribute smart apps. Because of their partnership with many companies, they have access to over 200 million consumers.

A CSS (Cluster Switch System) network is used to simplify the network architecture and improve network efficiency. It is used to correct the inefficiencies of the standard Ethernet network.

When you purchased an Apple Airport Modem you would have received a setup disk which should hold the software for both Mac OS and Windows OS.

Using this disk you should be able to configure the Airport to work with Windows XP. If the disk is not with it or the software not available then please visit the Apple.com website.

As the Airport basically has it's own system it requires this software to setup after which any unit can be connected with the correct passkey (if used).

The other difference between LAN and WAN, is the speed of the network. The maximum speed of a LAN can be 1000 megabits per second, while the speed of a WAN can go up to 150 megabits per second. This means the speed of a WAN, is one-tenth of the speed of a LAN. A WAN is usually slower because it has lower bandwidth.

Computers in a LAN can share a printer, if they are all in the same LAN. On the other hand, a WAN cannot share a printer, so a computer in one country cannot use a printer in another country. A LAN does not need a dedicated computer to direct traffic to and from the Internet, unlike a WAN that needs a special-purpose computer, whose only purpose is to send and receive data from the Internet.

Another LAN vs. WAN comparison is the cost of the network. A WAN is more expensive than a LAN. It is easier to expand a LAN than a WAN. The equipment needed for a LAN is a network interface card (NIC), a switch and a hub. On the other hand, the equipment needed to connect a WAN to the Internet is a modem and a router. The modem may be a cable modem or a DSL modem that is connected to a wall jack, while the router should be configured so that it can handle the packets traveling between the WAN and the Internet.

In LAN vs. WAN, there is a difference in the networking standard used. A LAN uses the Ethernet standard, while a WAN uses the T1 standard. Before Ethernet, the protocols used for LAN were Attached Resource Computer Network (ARCNET) and Token Ring. The protocols used for WAN are Frame Relay and Asynchronous Transfer Mode (ATM). Another protocol for WAN is Packet over SONET/SDH (PoS), where SONET stands for Synchronous Optical Networking and SDH stands for Synchronous Digital Hierarchy. The first WAN protocol was X.25, while an advanced WAN protocol is Multiprotocol Label Switching (MPLS). The hardware in a LAN is connected with 10Base-T cable connectors, while a WAN is connected via leased lines or satellites.

Here is an explanation of LANs and WANs. A LAN is easy to set up, as you need to slip the NIC into the PCI slot (for desktop computers) or PCMCIA slot (for laptop computers). You also need to install the driver for the NIC. The NIC can be connected to the network using the RJ45 port.

On the other hand, a WAN is very difficult to set up. There is often an appliance to optimize the WAN. There is also a device to cache WAN data, so workers in the branch office can quickly access documents. The router also has Quality of Service (QoS) built in, so that it gives priority to certain kinds of traffic.

There are various topologies available in LAN and WAN networking. The most common topologies in LAN and WAN networks are ring and star. The ring topology is a network in which every node (every computer) is connected to exactly two other nodes. The star topology is a network in which all the nodes (called leaf nodes or peripheral nodes) are connected to a central node.

Std. or straight-through Ethernet cable, by 568b specs, is Or/Wh, Or, Gr/Wh, Bl, Bl/Wh, Gr, Br/Wh,Br. Both ends.

Crossover is standard on one end, but Gr/Wh, Gr, Or/Wh, Bl, Bl/Wh, Or, Br/Wh, Br. You are crossing your transmit pair with your receive pair. Some sources would have you cross the other two pairs, as well, but it's not necessary.

Or = Orange, Wh = White, Bl = Blue, Gr = Green, Br = Brown.

A network is very similar to many roadways in many societies on earth today. The roadways are a means for people to travel from one place to another. The more people that are on the roadway, the more congested it is and this impacts the speed with which you can travel to your destination. A computer network (including the Internet) handles data a little differently than the multi-lane freeways/roadways, but essentially the quantity of people (users) accessing any given system will directly impact the speed and reactiveness of that system. Your local grocey store may be viewed in the same way. There are 'n' number of cashier/checkout bays in the store and under almost all conditions that is enough to handle the 'traffic' that flows in and out of that environment on a daily basis. There are peak times and lull times in each day. But, when threat of an impending storm is looming, that store may see a surge in activity that is well above the normal peaks and lulls it experiences throughout each day. The number of cashier/checkout bays becomes inadequate, but also the amount of products that are on the shelves is also inadequate. While a network or the Internet never 'runs out of product' on the shelves, it can see a surge in activity during certain catastrophic events (major earth quake, major fire, rioting, or terror attacks, etc) that results in a much higher level of traffic compared to other typical days. This will naturally cause the overall system to seem slow, sluggish, and in some cases completely inoperable. Though these are not perfect parallels (comparing a network to your local traffic or grocery store), the general theme is the same; any given system will experience a slower response time when the number of users, people, or just requests (a 411 Operator, for example) increases. If the system is over-designed and architected to handle even the highest level of traffic, then there will be almost no change in the response time.

The Client is the computer or device requesting data from the Server, which is a computer hosting the data. It works through a network protocol, more than likely TCP/IP.

The best topology for a cyper cafe is Bas topology. hope it helps

does network such as at&t control internet speeds? and if so how?

send answer to donaldhea@yahoo.com

No. A hub is hardware that connects different devices within a single network. You probably are thinking of a switch or router.

The router will install both routes in the routing table and load balance between the two.

If you are using a "white list" certain MACs are permitted, it's very hard to beat it.

If you aren't subnetting, then the host range for this network would be:

190.254.0.0 - 190.254.255.255

The above shows the IP address range, but not all addresses would be usable (mostly the first and the last addresses would probably be not assignable to a device).

Yes, you can.

1. Go to the Software Downloads section of the Microsoft Hardware website.
2. Select Gaming as the product type.
3. Select Xbox 360 Wireless Controller for Windows as the product (this is the software for the wireless gaming receiver).

It depends. For online use, some sites require payment of membership fee before use, some charges fee per transaction and some charges free. This is exclusive of cost incurred by the user/s from their network provider.
