The port numbers ranging from 0 - are restricted; they are reserved for use by well-known services such as HTTP and FTP and other system services. It is a way to translate requests that are incoming into a routing server to the relevant devices or servers that it knows about in the LAN. However, other forms of communication don't require such strict standards. At this point, you should understand some basic, high-level concepts that will enable us to better discuss the topics to come. Application : The application layer is the layer that the users and user-applications most often interact with. Otherwise, you end up with a jumbled HTML file, a corrupt zip file, or some other invalid information. When two applications want to communicate to each other reliably, they establish a connection and send data back and forth over that connection. While networking is often discussed in terms of topology in a horizontal way, between hosts, its implementation is layered in a vertical fashion throughout a computer or network. UDP User Datagram Protocol is a protocol that sends independent packets of data, called datagrams, from one computer to another with no guarantees about arrival. This level of networking utilizes ports to address different services.

  • This document will provide a basic overview of some common networking concepts. We will discuss basic terminology, common protocols, and. medium. A computer network is a collection of two or more connected computers.

    such as remote login, file transfer, electronic mail, the World Wide Web and. Lauren has decided to review basic network concepts with her coworkers as . began filling up, partly because everyone had a copy of every document.
    Typically, your server will have one configurable network interface for each Ethernet or wireless internet card you have.

    Sending datagrams is much like sending a letter through the postal service: The order of delivery is not important and is not guaranteed, and each message is independent of any other. TCP is one of the protocols that encapsulates data into packets.

    In addition, it will define a virtual network interface called the "loopback" or localhost interface. Physical : The physical layer is responsible for handling the actual physical devices that are used to make a connection.

    UDP User Datagram Protocol is a protocol that sends independent packets of data, called datagrams, from one computer to another with no guarantees about arrival.

    These classes provide system-independent network communication.

    Many times, administrators configure one interface to service traffic to the internet and another interface for a LAN or private network.

    This layer involves the bare software that manages physical connections as well as the hardware itself like Ethernet.

    The "eth0" interface will be configured to handle traffic from the internet, while the "eth1" interface will operate to communicate with the private network. Networking works by piggybacking a number of different protocols on top of each other.

    There are many other protocols that we haven't covered that are equally important.

    This networking Java tutorial describes networking capabilities of the Java platform, working with URLs, sockets, datagrams, and cookies.

    Our device networking tutorials help you understand basic networking protocols and techniques as well as serial to Ethernet/ device server technology.

    HTTP defines a number of functions that tell the remote system what you are requesting. If the client misses a packet, it doesn't really make sense to resend it because the time will be incorrect when the client receives it on the second try. A network interface may be associated with a physical device, or it may be a representation of a virtual interface.

    Packet : A packet is, generally speaking, the most basic unit that is transfered over a network.

    It defines the four separate layers, some of which overlap with the OSI model:. Networking works by piggybacking a number of different protocols on top of each other.

    These ports are called well-known ports.

    This is a way for the two ends of the communication to acknowledge the request and agree upon a method of ensuring data reliability.

    Introduction A basic understanding of networking is important for anyone managing a server.

    While networking is often discussed in terms of topology in a horizontal way, between hosts, its implementation is layered in a vertical fashion throughout a computer or network. If you want to speak to Aunt Beatrice in Kentucky, a connection is established when you dial her phone number and she answers.

    If the client makes two requests and receives packets from the server out of order, it doesn't really matter because the client can figure out that the packets are out of order and make another request. IP addresses are unique on each network and they allow machines to address each other across a network.

    DNS stands for domain name system. It is an application layer protocol used to provide a human-friendly naming mechanism for internet resources.

    This model defines seven separate layers.

    This layer is aware of the endpoints of the connections, but does not worry about the actual connection needed to get from one place to another.

    Application : The application layer is the layer that the users and user-applications most often interact with. At this point, you should be familiar with some basic networking terminology and be able to understand how different components are able to communicate with each other.

    For instance, if you have two network cards in your computer, you can control and configure each network interface associated with them individually.
