What are the differences between b g and n wireless routers Can they all be used with a built in wireless card?

The Letters Stand For Different Types of signals frequencys essentially. Wireless N is the best and newest. It doesn't interfear with other wireless devices like cellphones,microwaves, and other electronic devices. Wireless N also has alot better penetrating range and coverange area. It also allows for quicker internet access without the interference Wireless G is todays Standard. Alot of devices use this today. Wireless B is the older Standard Only a wireless N Wireless adaptar is compatible with N,G, and B routers. The same cannot be said about Wireless G and B.

Why is bgp needed?

BGP is the routing protocol used on the Internet to exchange IP routes, and in order for routing on the Internet to work properly, all Internet-Speaking Routers must talk the same "language" (protocol), which currently is BGP (Border Gateway Protocol). So on the Internet, BGP is used to exchange public IP addresses and works as the glue of the Internet.

BGP is also sometimes used on internal networks, alongside technologies like MPLS etc.

Note that there are two kinds of BGP - eBGP (external BGP), and iBGP (internal BGP). Internal BGP is normally used within an AS - Autonomous System (usually, a company or an ISP), and eBGP peerings are used to fascilitate external Internet traffic exchange of IP routes.

So, the Internet is basically just a bunch of "bubbles" (Autonomous Systems), and eBGP peering is the mechanism that allows the bubbles to exchange information.

What is next hop in computer networking?

Information in large computer networks often gets sent over several "hops" - each hop is a router or server, or some equipment with similar capabilities. The "next hop" simply tells you where an information packet will be sent next - say, to which router. This router must then again decide where the information is to be sent.

What is the shannon capacity?

If G is an undirected chart, it can be used to classify a communications waterway in which the symbols are the chart vertices, and two secret code may be puzzled with every other if their symbols in each arrangement are equivalent or adjoining. The computational difficulty of judgment the Shannon capacity of such a conduit lingers unfasten, but it can be higher bounded by an additional significant chart invariant, the Lovász figure.
