The Domain Name System (DNS) is a TCP/IP name resolution system that resolves hostnames to IP addresses. How do you think this relates to the WEB pages we browse?
The Domain Name System (DNS) is an application layer protocol.which is used to map an URL into an IP address.
Suppose you want to visit on www.HomeworkLib.com to do so you have typed www.HomeworkLib.com in the URL and hit the enter button then after the role of DNS come into action and it will map the domain name www.HomeworkLib.com into a unique IP address so that Client/Server can identify each host uniquely on the Internet with a unique user-friendly name.
.The Domain Name System (DNS) is divided into three sections namely:-
1. The generic domain is used to specifying an organization type. for example .com, .edu, .org etc
2. The country domain whose role is to specify the Country domain. for example .uk, .in, .us etc
3. Inverse Domain which role is in address-to-name resolution.for example IP->DN.
.The Domain Name System (DNS) is also responsible for keeping tracing all computers, services, and resources.

Which TCP/IP Application layer protocol provides IP address resolution for domain names? A. DHCP B. DNS C. SMTP D. SNMP
please give me clear picture Section 1: DNS nslookup The Domain Name System (DNS) translates hostnames to IP addresses, fulfilling a critical role in the Internet infrastructure. In this lab, we’ll take a closer look at the client side of DNS. Recall that the client’s role in the DNS is relatively simple – a client sends a query to its local DNS server, and receives a response back. Much can go on “under the covers,” invisible to the DNS clients,...
Discuss how you would configure your Linux distribution to perform name resolution using DNS. Compare and contrast the following programs which are helpful in debugging TCP/IP networks: nslookup, host, dig, whois. Ensure you provide terminal output in your discussion.

Explain why DNS (Domain Name System) employs a caching mechanism of queries and discuss whether you would recommend using DNS for fast moving mobile users.
1.DNS can not work if the hostnames are not hierarchal? Explain? 2. Give two scenarios where DNS protocols (from two hosts) gets two different IP address for the same hostname. 3. If you have a 100% reliable network layer, should you use TCP or UDP at the Transport layer? Explain your answer? 4.Is it is possible for an application on top of UDP to have a reliable data transfer? Explain? 5.Suppose that a Web server runs in Host C on...
