what is UDP in networking?
146712
With help of NAT(Network Address Translatior) u can connect ur all computer to the internet. NAT use one public ip address & u can map all private address to it to access internet.it converts private add to public address. Private addtess are thr range of ip address which is reserved to use privatly by an org. u can not use it over internet.Public ip address r used to connect devices on internet. To setup network with 10 computers put ur public ip address on server & with help of proxy u can access internet on all PC

The same way you transfer any kind of UDP packets; dial-up makes no difference.  Usually users are not concerned with the underlying transport mechanisms, TCP or UDP.  UDP packets may be transferred programatically using standard methods.\n\nWhat are you trying to accomplish?

This is a feature that is mostly used in corporate environment to implement proxy functionality.  One port is connected to the outside world and the other is connected to the internal network, the computer can also be plugged into two independent sub-network

data over IP is nothing but sending data within the IP protocal.generally IP is used to identify the logical connection of the destination system and after establishing the connection the data is been transfered.now in data over ip the data is also sent with the source and destinition information.that is we embbed the data within the ip packet.i hope this might be the correct answer.\nall the best and best regards,

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

All Internet traffic is TCP/IP (Transmission Control Protocol/Internet Protocol).  Everything you send to Hotmail, and everything they send back, is transported over TCP/IP.\n\nThe same is true for any web site, Instant Messaging application, music download, etc.\n\nThe rare exception is Voice over IP (like Vonage) which uses UDP/IP.  It's less reliable than TCP, but it's a simpler protocol and works well for the zillions of tiny packets that make up a phone call.

You are going to have to be much more specific in your question.  Are you referring to a LAN operating system, just connecting a few PC's together, or a multi-user application software (and in this case, what application?)

TCP - Abbreviation of Transmission Control Protocol, and pronounced as separate letters. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent. \n\n\nPort -   \n  \n(n.) (1) An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards. Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices. \nAlmost all personal computers come with a serial RS-232C port or RS-422 port for connecting a modem or mouse and a parallel port for connecting a printer. On PCs, the parallel port is a Centronics interface that uses a 25-pin connector. SCSI (Small Computer System Interface) ports support higher transmission speeds than do conventional ports and enable you to attach up to seven devices to the same port. \n\n(2) In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic. Also see Well-Known TCP Port Numbers in the Quick Reference section of Webopedia.\n\n(v.) To move a program from one type of computer to another. To port an application, you need to rewrite sections that are machine dependent, and then recompile the program on the new computer. Programs that can be ported easily are said to be portable.

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.

The Internet ("inter-" + "network") is a large computer network made up of several nodes of smaller networks. Ultimately, the Internet is just a system for billions of computers to be able to send data to eachother at any given moment.\n\nThe Internet relies on the Internet Protocol (IP), layer 3 of the OSI model. IP provides a way to specify where you want to send data ("IP addresses"), but not much that plays a very obvious role on the Internet...\n\n...And what exactly is a protocol?\nA protocol is just a way of doing things. It can be very detailed and strict or very lenient. For example, the way you get dressed in the morning could be called a protocol. At the same time, the way to file your taxes is a protocol.\n\nProtocols provide guidelines that should be followed for 'optimal' performance - if you send you taxes to the wrong address, you'll have an angry government. If these are not strictly adhered to, something might horribly break. But when talking about computers and "networking", a protocol is usually a "communications" mechanism that helps computers talk to - and understand - eachother.\n\nThe same people who created the Internet Protocol also created higher level protocols (protocols that directly rely on IP). A couple of these protocols are the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Again, these protocols don't explain what the most obvious parts of the Internet are - like WWW and FTP - but they provide some insight into the multi-layered complexity of it all.\n\nTCP and UDP are the two more popular Internet protocols. There are higher level protocols that rely on these, and inevitably even higher level protocols than those. But TCP and UDP (with IP) provide the basic underlying functionality of the Internet and define an important concept: the client-server networking paradigm.\n\nThis paradigm has two parties to every discussion, a server and a client. A server, so named because it "serves" clients, listens to certain types of network traffic and when it "hears" its name being called, it answers. A client is the one doing the calling.\n\nA server, also known as a service or daemon, is really just a program running on somebody's computer. It is designed to provide some functionality for requesting parties (clients). Likewise, a client is a computer program designed to talk to a server. Many such clients make these "discussions" transparent to a user (and many don't require any user interaction at all).\n\nServers rely on protocols in a way to understand their clients and vice versa. If you were to talk to someone who only spoke a language you didn't understand, you couldn't derive anything useful from your attempt at conversing. This is the case with servers as well. The protocols define languages the clients and servers can use to better understand eachother.\n\nAn example of such a protocol is the Hypertext Transfer Protocol (HTTP). HTTP provides a way for servers to serve documents (computer files) to requesting clients. Namely, a "web browser" (a client) connects to a "web server" (a server) and asks for a "web page" (a computer file). The server responds by telling the client something in language it understands - it says "here is the document you wanted", "I couldn't find that", or "there was a problem".\n\nSince you are writing PHP code, you probably understand that HTTP has some more options than just those, and what HTML is. With that information, you have a pretty good idea of what the World Wide Web is. WWW does not make up the Internet, but many such things - FTP, gopher, NNTP, POP, IMAP, SMTP, etc., etc., etc. - together make up the Internet.\nWith all of these, the programs that support them, and the people that require them, the Internet works. Really, how the Internet works is that millions

The Dynamic Host Configuration Protocol (DHCP) is a set of rules used by a communications device (such as a computer, router or networking adapter) to allow the device to request and obtain an Internet address from a server which has a list of addresses available for assignment.\n\nhttp://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

You will have to go thru the firewall  of thegateway thru (usually) port forwarding. This will have to be setup by the System or Network Admin.\n\nThere are two ways UDP or TCP/IP you will probably use the latter.\n\nThink of it like a door. The front of the door is to  the internet, it has an address (IP#) The back of that same door has a different address. You have to go thru two addresses to get to the LAN network so that you can acces the computers on that Network (LAN Local Area Network).\n\nYou do this thru port forwarding or VPN (Virtual Private Network). Either way you need the Admin to set it up as a direct line

Assuming you mean pinging: \n\nOn a unix machine type "man ping" \nOn a windows machine type "ping /?" \n\nUseless facts about ping:\nPing uses ICMP packets that are only designed to go to an IP address and elicit a reply. \n\nICMP is usually the lowest priority on a router and will be the first protocol dropped when a router gets busy. \n\nMany firewalls and sysadmins prevent ICMP traffic as a security measure making it unreliable alone in diagnosing a problem.
