Gateway And DNS Servers I. Function of IP address, subnet mask, default gateway and DNS servers a. IP address Internet Protocol Address that people mostly call IP address is the numbers to connect from one computer to other computer network, and every device has to connect to the Internet at least one IP address. In the Internet system, it identifies and locate network interface on device. It also shows where traffic come from and is going. It defends from a user’s view in the DNS which provides

This paper is to inform the reader of the benefits of DNS and DHCP within a network. DNS stands for “domain system name” These are the human readable web addresses we use every day. Unfortunately, computers do not understand human language and web addresses must be made readable to computers. This is where DNS comes into play. If you were to type in google.com in the address bar of your browser, google.com would appear. Computers use numerical IP addresses to translate “Google.com”. Google’s IP

Unit 8 Assignment 2 Benefits of Active Directory An Active Directory structure is a hierarchical arrangement of information about objects. The objects fall into two broad categories: resources (e.g., printers) and security principals (user or computer accounts and groups). Security principals are assigned unique security identifiers (SIDs). Each object represents a single entity—whether a user, a computer, a printer, or a group—and its attributes. Certain objects can contain other
