TFTP is used often in the router configuration. TFTP is used when a file transfer does not require an acknowledgment packet during file transfer. Web browsers can make FTP requests to download programs from links selected on a Web page. FTP is still used for file transfer purposes, most commonly as a central FTP server with files available for download. FTP is a character-based command interface, although many FTP applications have graphical interfaces. The File Transfer Protocol (FTP) is used to connect to remote computers, list shared files, and either upload or download files between local and remote computers.įTP runs over TCP, which provides a connection-oriented, guaranteed data-delivery service. One of the earliest uses of the Internet, long before Web browsing came along, was transferring files between computers. SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. It is mainly used by Microsoft Windows-equipped computers. The SMB protocol defines a series of commands that pass information between computers. It allows networked computers to transparently access files that reside on remote systems over a variety of networks. To collect the information in a usable form, a management program console polls these agents and downloads the information from their MIBs, which then can be displayed as graphs, charts and sent to a database program to be analyzed. The gathered data is stored in a MIB (management information base). These agents can be loaded onto managed devices such as hubs, NIC's, servers, routers, and bridges. SNMP uses small utility programs called agents to monitor behavior and traffic on the network. Simple Network Management Protocol is a TCP/IP protocol for monitoring networks and network components. > Basic Concepts of NAT Explained in Easy Language SNMP (Simple Network Management Protocol) To learn more about NAT, you can check the following tutorial. In dynamic NAT, the global address assigned to the internal user isn’t that important, since outside devices don’t directly connect to your internal users-they just return traffic to them that the inside user requested. Dynamic NAT is used to translate source IP addresses in packets as they go out of your network. Static NAT is used to translate destination IP addresses in packets as they come into your network, but you can translate source addresses also. In the dynamic NAT, an automatic address translation is performed by an address translation device. In the static NAT, a manual translation is performed. Two basic implementations of NAT can be used: static and dynamic. This can be a source address or a destination address. This protocol translates one IP address to another. NAT stands for Network Address Translation. Without DNS service, your browser will not be able to access Yahoo's site. Your browser accesses Yahoo's site and displays it on the viewport. DNS server translates the address into the IP address and sends the IP address of Yahoo's site. Your web browser connects the configured DNS server and sends a request to convert the entered address into the IP address. For this, you enter the following address in your web browser. Suppose you want to access the home page of Yahoo's site. When we access a node by its name, the DNS service translates the name into the IP address. DNS service allows us to map a name to an IP address. By default, nodes use IP addresses to identify each other on the network. This service allows us to access a node by its name. To learn how IP protocol creates and manages IP addresses, you can check the following tutorial.ĭNS stands for Domain Name Service.
