IP ADDRESS

Receiving unwanted email from unknown address is surely annoying. In some case, we could become very curious about the sender and then try to trace the sender with any tools we have. Years ago, tracing email address might be a difficult thing to do, but since the informational technology has been develop very fast, it now can be done easily. The technology has enabled us to trace the sender of anonymous email form unknown address.

As we can see at Track-ip.com, there is a tool called reverse email lookup that enables us to trace email address. This website provide many easy-to-use tools where we can search any anonymous emails instantly. Besides email, this website also gives us a chances to Track IP Address. We certainly often heard that there are many fabricated websites that offers fictitious products or services. This fact should makes people more aware about the importance of checking the address and location of a website before we use or purchase any products or services from them.

FYI, information about websites’ address and location can be obtained from their IP Address. Meaning to say, IP Address becomes a validity proof of a website. To start tracking IP Address using this website, you just need to enter the url and within seconds, this website will reveal the information for you. Informations provided should be very useful for safe and secure internet transactions. So, if you are interested using their tools, just visit their website for further information.

BROADBAND PLAN

Broadband access is a vehicle that allows the delivery of an entirely new breed of media services and communications-oriented applications. In the long run, it is these new services and applications that will differentiate broadband from dial-up Internet access and give consumers a reason for subscribing to broadband. Audio and video are the obvious cornerstones of this coming high-speed revolution. Speedy connections coupled with always-on access will improve the consumer multimedia experience and change the types of business models that are viable in the interactive marketplace. As use of broadband grows to more than 20 million subscribers by 2004, traditional media companies may uncover opportunities for growth and acquisition in these alternative content categories enabled by the high-speed Internet. Broadband will not replace traditional media formats as they exist today. But it will emerge as a new source of fragmentation, siphoning off enough listeners and viewers to affect established media entities and their long-term growth.

Federal Full broadband lines are lines with information carrying capability in excess of 200 Kbps in both directions, simultaneously. One-way broadband lines are lines with information carrying capacity in excess of 200 Kbps in one direction (typically downstream) and less than or equal to 200 Kbps in the other direction (typically upstream).

ROUTER CONFIGURATION

Routers are physical devices that join multiple wired or wireless networks together. Technically, a wired or wireless router is a Layer 3 gateway, meaning that the wired/wireless router connects networks (as gateways do), and that the router operates at the network layer of the OSI model.

Home networkers often use an Internet Protocol (IP) wired or wireless router, IP being the most common OSI network layer protocol. An IP router such as a DSL or cable modembroadband router joins the home's local area network (LAN) to the wide-area network (WAN) of the Internet.

By maintaining configuration information in a piece of storage called the routing table, wired or wireless routers also have the ability to filter traffic, either incoming or outgoing, based on the IP addresses of senders and receivers. Some routers allow the home networker to update the routing table from a Web browser interface. Broadband routers combine the functions of a router with those of a network switch and a firewall in a single unit.

MAN Network

A Metropolitan Area Network (MAN) is one of a number of types of networks (see also LAN and WAN). A MAN is a relatively new class of network, it serves a role similar to an ISP, but for corporate users with large LANs. There are three important features which discriminate MANs from LANs or WANs:

1. The network size falls intermediate between LANs and WANs. A MAN typically covers an area of between 5 and 50 km diameter. Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings or as large as the North of Scotland.
2. A MAN (like a WAN) is not generally owned by a single organisation. The MAN, its communications links and equipment are generally owned by either a consortium of users or by a single network provider who sells the service to the users. This level of service provided to each user must therefore be negotiated with the MAN operator, and some performance guarantees are normally specified.
3. A MAN often acts as a high speed network to allow sharing of regional resources (similar to a large LAN). It is also frequently used to provide a shared connection to other networks using a link to a WAN.
   

A typical use of MANs to provide shared access to a wide area network is shown in the figure below:

Use of MANs to provide regional networks which share the cost of access to a WAN
