Roles Of Dns Domain Name System

Once one of the computers is properly configured as a file server, users can access the storage by mapping the drives on the respective computers. The file server will be mapped as a drive and users can store, edit and access files directly from the shared storage disk. The disk will be connected to each computer. For example, when a user needs to access any file from the file server, he/she can access the drive that will now be mapped on the every computer (Science - Opposing Views, 2014).

A web server is a PC that opens pages on a browser on request. It sends the web address of the page that has been requested to the web browser. They have an IP address and possibly domains and are essential for an ecommerce because ecommerce is online and a web server is what you need to surf the web.

A hierarchical system of servers and services specifically designed to translate IP addresses into domain names (forward lookups) as well as the reverse (reverse lookups) is called:

When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.

Local Name Server: a cached name server within a DMZ that speeds up name queries for clients located on the local network. The information on this server is received from the authoritative name server.

The IP address is given a unique identification it is one of kind IP address, so it can be trace for any internet activity and find the exact location of website. Domain names are used because it is easier to remember the name rather than the entire website address. All computers on the net have what area unit termed net Protocol addresses ordinarily called associate degree scientific discipline address to be ready to communicate across the network. These addresses, that area unit assigned to all or any computers on a network, area unit created of numerals separated by a dot that don't seem to be essentially simple for North American country to recollect. Therefore, whereas computers simply use these scientific discipline addresses to attach and communicate with one another, it's somewhat more difficult for North American country. It's with keeping such in mind that, net designers and controllers have return up with a translation system that identifies additional simply remembered characters with every and each scientific discipline address. With DNS we need to have the integrated namespace so following DNS use is proposed: an internal DNS namespace, used only on your own network; internal DNS to communicate with external DNS forwarding; and an external DNS namespace to communicate with external

Files are stored at server disk. Clients do read and write operations on the network.

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

DNS- DNS stands for domain name server and is a network of servers that keep track of Internet Domain Names. Its main job is to authenticate and find domains. It translates IP Addresses into numbers, for example, 172.194.40.143 translates into

1. The process of obtaining an IP address for a computer name (for example, “Computer A”) is called __________. Name Resolution

Most often, you will install DNS servers on all domain controllers. If, however, you have reason not to deploy DNS servers on every domain controller, you can follow these guidelines to choose where to place your DNS servers. In general, place your DNS servers at a location on your network that is centrally accessible to your clients. It is often most practical to use a DNS server on each subnet. There are several questions to consider when you are deciding where a DNS server is needed.

Domain Name System- The name of both a protocol and the system of actual DNS servers that exist in the world. In practice, DNS provides a way for the world to distribute the list of matching host name/IP address pair information, letting each company maintain its own naming information, but allowing the entire world to discover the IP address used by a particular host name, dynamically, using DNS protocols, so that any client can refer to a destination by name and send IP packets to that host.

The role of an IP address is to locate each device in the network. For example, having a Roku, Xbox One, two IPhone, a wireless printer, each device has its address. The domain name is a name given to companies, entities to communicate and share data through the network (e.g. intranet, internet, cloud).

When connecting your internal network to the internet the need route the packets between the two networks happens inside a router. This translation between the two different networks is known as network address translation (NAT). There are advantages when using NAT as well as disadvantages to the end user, network administrators and overall functionality of the network. We also have to understand the differences between IPv4, IPv6, and the need for NAT in each as they are different protocols and will operate differently ("Network Address Translation," 2015).

The Domain Name System or DNS is an international address system developed to ensure that every computer connected to the Internet has its own address. DNS assigns addresses to Internet web servers [10]. However, in the DNS system, that address is actually a set of numbers like 173.194.39.78. This set of numbers is called the computer's Internet Protocol (IP) address.
