In our previous post you can read about server, what is server and how it makes to give his resources avaiable to Client Computers. Now we will se the other par of Client-Server architecture, Host in the role of Client.
MAC address, what that means and what MAC address actually is?
Let’s make it simple
The Layer 2 address is unique on the local network and represents the address of the end device on the physical media. In a LAN using Ethernet, this address is called the Media Access Control (MAC) address. When two end devices communicate on the local Ethernet network, the frames that are exchanged between them contain the destination and source MAC addresses. So we can say that unique identifier called a Media Access Control (MAC) address was created to help in finding the source and destination address in an Ethernet network. MAC addressing is added as part of a Layer 2 ethernet frame. An Ethernet MAC address is a 48-bit binary value expressed as 12 hexadecimal digits.
WAN – The phrase “wide area network” in a word is known as WAN. That wide ranging network works collectively with the help of hardware such as computers and related resources. Cisco has introduced a lot of devices such as modem and routers for WAN, protocols and technologies such as ATM, Cisco frame relay etc so to provide a better wide area network (WAN) environment.
This article will help you understand and manage basic configuration of devices from different brands. With Cisco and Juniper router configurations, you will be able to manage network that is made of devices from other sellers, not only Cisco. In that way, you will not be in problems when making some implementation, changes or troubleshooting connectivity issues on multi-brand network topologies.
Online visitors usually want to know their IP address for certain reasons like: for game playing purpose, technical support, remote connection and proxy detection etc. Moreover, they can also check is their address changed or still there are using their personal e-mail server. If you want to gallop your personal e-mail or web server then static IP address will best for you.

Two main functions of an IP address are given under:
Generally, DNS represents to Domain Name System. But sometimes it is referred to Domain Name Service too. Anyhow, DNS system is a multi-level distributed naming system for whether computers, services, or any other resource, connected to the internet or else a private network. The main purpose of this system is to join together relevant information and domain names that are allotted to online participating entities.
