Types of computer network\n\n1) A bus network is a network architecture in which a set of clients are connected via a shared communications line, called a bus. There are several common instances of the bus architecture, including one in the motherboard of most computers, and those in some versions of Ethernet networks.\n\nBus networks are the simplest way to connect multiple clients, but often have problems when two clients want to transmit at the same time on the same bus. Thus systems which use bus network architectures normally have some scheme of collision handing or collision avoidance for communication on the bus, quite often using Carrier Sense Multiple Access or the presence of a bus master which controls access to the shared bus resource.\n\nA true bus network is passive – the computers on the bus simply listen for a signal; they are not responsible for moving the signal along. However, many active architectures can also be described as a "bus", as they provide the same logical functions as a passive bus; for example, switched Ethernet can still be regarded as a logical bus network, if not a physical one. Indeed, the hardware may be abstracted away completely in the case of a software bus.\n\nWith the dominance of switched Ethernet over passive Ethernet, passive bus networks are uncommon in wired networks. However, almost all current wireless networks can be viewed as examples of passive bus networks, with radio propagation serving as the shared passive medium.\n\n\n2) Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, or hub computer which acts as a router to transmit messages.\n\nWhen applied to a bus-based network, this central hub rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only. The failure of a transmission line linking any peripheral node to the central node will result in the isolation of that peripheral node from all others, but the rest of the systems will be unaffected.\n\nIf the central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time (i.e. to and from the central node) plus any delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems.\n\n3) A ring network is a topology of computer networks where each node is connected to two other nodes, so as to create a ring. The most popular example is a token ring network.\n\nRing networks tend to be inefficient when compared to star networks because data must travel through more points before reaching its destination. For example, if a given ring network has eight computers on it, to get from computer one to computer four, data must travel from computer one, through computers two and three, and to its destination at computer four. It could also go from computer one through eight, seven, six, and five until reaching four, but this method is slower because it travels through more computers.\n\n4) Mesh networking is a way to route data, voice and instructions between nodes. It allows for continuous connections and reconfiguration around blocked paths by "hopping" from node to node until a connection can be established.\n\nMesh networks are self-healing: the network can still operate even when a node breaks down or a connection goes bad. As a result, a very reliable network is formed. This concept is applicable to wireless networks, wired networks, and software interaction.\n\nA mesh network is a networking technique which allows inexpensive peer network nodes to supply back haul services to other nodes in the same network. It effectively extends a network b

Internet is a network of inter-connected computers with different Operating Systems and protocols working on different networks.\nTo connect all the networks we need a gateway which convert one protocol data to different so all networks can connect.

use LAN cable.\nif you want to connect more than 2 computer. use a router and a hub. \nall computer can be used to acces the internet at the same time.

LAN (Local Area Network)\n-Is a network that's usually within an area of 1km.\n-Privately owned N/Ws\n-Widely used to connect PCs & workstations in offices & factories to share resources & exchange info\n-They are disyinguished from other kinds of N/Ws by 3 characteristics: size, transmission technology & topology.\n-Often use transmission technology consisting of a single cable to which all machines are attached.\n-Have speeds of upto 100mbps\n\nMAN (Metropolitan Area N/W)\n-Is simply a larger version of LAN & can be within a city/upto an area of 10kms.\n-Might cover a group of nearby corporate offices & might be private/public.\n-Can support both data & voice & might even be related to the local cable TV N/W\n\nWAN (Wide Area N/W)\n-Spans a large geographical area, often a country/continent.\n-The Internet is a WAN\n-A WAN contains a collection of machines intended for running user programs\n-Transmission speed is low & error rate is high\n-Connected using telephone cables/satellites \n-Are public

fiber optics, T-1, T-3, to name a few. there are a few but mostly used by businesses and very expensive. I own a computer business and run T-1. It's more than i need.

Routers are Layer 3 (Network Layer)\nHubs and Switches are Layer 2 (Data Link Layer)\n\nCheers :)

My god, I am trying to think of a way to explain it, there are a million links if you search, but think of a million large spider webs hooked together, you do have one (Company) thats does take care of all the names, somebody has to so there would only be only one of each name, You have millions of web servers, that are computers that can have 1 to 50,000 sites on each one.\nIf you use  your telephone line and modem or high speed connection, the computer connects to the ISP's server. Once there, the ISP acts as a gateway connecting you to any computer hooked to the World Wide Web, using browsers like Internet Explorer or Netscape. \n\nNext, you type in a URL (Uniform Resource Locator) - such as www.yahoo.com. The computer translates this into a number - the IP address - that is unique to every web page and computer, making it possible for machines to recognise each other. The machines then 'talk' to each other using 'languages' called protocols. Specifically, the protocol in question is TCP/IP, which allows computers to describe data to one another over a network. \n\nEvery computer on the WWW understands these two protocols, and can therefore communicate amicably. TCP/IP is actually two different things. TCP (Transmission Control Protocol) takes the information you want to send over the Internet, and breaks it into small chunks of data called 'packets' that can include programming, text, pictures, sound or video in various combinations. IP (Internet Protocol) takes over and routes those packets through computers to get them to their destination. \n\nWhen the packets arrive at the destination computer, TCP reassembles them into what you finally see as a web page on your computer screen. TCP/IP is further broken down into specialised protocols like STMP (which works with email), Ftp (for simple file transfers) and the omnipresent 'http://' (Hypertext Transfer Protocol), which is how Web browsers work. \n\nSounds a bit intimidating? Just remember: you have gone through each of these steps every time you have logged on to the Internet! .

Hey go to this link and you will find some good information about networking http://computer.howstuffworks.com/question353.htm

Since you are asking for a lot of information, I will give you a pointer instead of typing it all in.  This should help you quite a bit.\n\nhttp://en.wikipedia.org/wiki/Network_routers#Types_of_routers\n\nGood luck,\nJeffrey

Both support TCP/IP which you are using now. Set up each computer with an address on the same subnet.

Well since this question is under networking do you mean like Serial, fastethernet, ethernet, BRI, dailer, interfaces?\nthen of course there are different types of serial interfaces and such do you need those because unfortunetly I do not know WAN products that much.\n\nIf you clairfy your question a little bit more I am sure one of will be able to provide the right answer.
