A DMZ allows for a publicly accessible zone without compromising the internal network.
The purpose of a DMZ is to protect the internal Local Area Network from publicly available hosts on the network. A DMZ is a security zone which sits between the internal networks (LAN) and internet. By placing the public server in a DMZ outside users avoid establishing a connection to their internal network further avoiding potential security breaching.
(Internet) ----- FW--- DMZ -------FW--- LAN
Above is a basic representation of a DMZ. As you can see the DMZ resides between two firewalls. If the user wishes to pass to the LAN they must penetrate the firewall before they can gain acccess to internal LAN resources .
A firewall is usually placed in front of a group of machines and its primary function is to control communication from and to this group of machines. Communication between two machines over the Internet is a stream of packets (datagrams) send in both directions. The firewall examines all packets that is about to be routed through the machine and, based on a set of rules, determines if the packet is allowed to pass through the machine or not. This functionality is often referred as a packet filter. The secondary function of a firewall is to modify the packets passing through the firewall. This is called Network address translation (NAT), as the modifications usually applies to either sender or receiver information contained in the packets. NAT can for example be used to allow machines without a public addressable Internet protocol (IP) number, to access the Internet through a firewall, by using the IP-number of the firewall as the sender identification. This is also called ip masquerading, as it disguises the address of the machines behind the firewall. www.goldstardailynews.com
To indicate to the network that a particular node is about to transmit data
To determine the network or subnet address of an IP address
CheckPoints VPN programs are used for simplicity in creating and managing a VPN, or Virtual Private Network. Their programs allow the user to easily manage and control their VPN for privacy and security, from nearly anywhere.
Network Attached Storage is short for NAS, which is computer storage connect to a network. RAID is a hard drive or storage container, which provide access to the file network.
The purpose of the Sonicwall firewall is to provide security for the network and to monitor the traffic entering and exiting a network. This prevents malware and intrusions.
To allow university and government engineers to do research and/or work from any location on the network
Security. People on the larger network can't see the smaller subnet, good for departments like Research.
For this purpose you have to use firewall, or you can check off file and printer sharing for Microsoft Network in Wireless Network Connection Properties. Here you can find pictures how to http://picasaweb.google.com/archangel.dmitry/DropBox?authkey=OrLcAc425Mc
Hardware can be purpose-built for a single job, and can perform that job faster than any general-purpose hardware running a software implementation.

Security. People on the larger network can't see the smaller subnet, good for departments like Research.
Scope refers to the extent and boundaries of a project or task, outlining what is included and what is not. Purpose, on the other hand, defines the reason or goal behind the project or task, illustrating the intended outcome or objective to be achieved. In essence, scope defines the parameters of work while purpose clarifies the reason for undertaking the work.
