A router is a device, two or more computer networks, and selective exchange of packets between them. Each packet contains the address of a router to determine whether you can use the source and destination are on the same network, or, if the data packet to be transferred from one network to another. Where more than one router is a massive collection on the Internet, the address of the target system, routers exchange information, so that each router can build a table that shows the relationship between any two systems on the network preferred way.
Routers, network equipment is a specialized software and hardware, the routing problem and sharing information. The router has two or more network interfaces such as copper cable, fiber or a wireless network or networks of different standards, with different physical network types. Each network interface small computer dedicated from one form into electronic signals to the other.
Routers connect two or more logical subnets, do not share common network addresses. The subnet in the router does not reflect on the router 1-1 term "third-level exchange of the physical interface" are often used interchangeably with the terms "routing". Exchange term commonly used to describe the data between two network devices common forwarding address online. It is also known as the second layer of exchange or switching center.

Structured wiring connection
Cabling is building or campus telecommunications cable infrastructure, which consists of many small elements called structured normalized subsystems. Design and installation of structured cabling is covered by a set of standards that define the wiring data centers, offices and residential voice and data, using Category 5 (CAT 5E) or category 6 cable (CAT 6) and modular contacts.
These rules determine how to place wires in a star formation, so that all points by the end of the central patch panel, usually mounted on 19-inch rack, which can be determined exactly how to use those links. Each patch can be played in a data network to connect to the normally also rack together or spots in the telecommunications patch panel 'which forms a bridge to a private exchange (PBX) telephone system so that the voice port connection.

Wi - Fi
Wi - Fi is connected. At home, Wi - Fi wireless connection you and your favorite content and communication on your cell phones, computers, media players and other devices - all without cumbersome cables. When you're walking and Wi - Fi allows you to connect to the Internet or your own office from the airport or cafe, and helps you stay productive when you're far away from home. Now, imagine doing all these things very easily and quickly - without worrying about finding a wired network connection. This is a wireless network connection.
UDP connections
UDP-User Datagram Protocol is very easy to transport layer protocol. TCP does not provide the same quality, and therefore be regarded as `` unreliable. ''So, although it is not suitable for some applications, but there is more reliable and stronger than the other programs that use TCP. TCP
TCP is a transport layer protocol. It will sit on top of network layer protocol designed to run on top of intellectual property. As IP was designed to bear, among others, TCP packets. However, TCP and IP were designed together, and if you have one, you usually have more internet protocol referred to as `` a set of TCP / IP protocol. The TCP itself''an important function, and we will soon cover the number.

Virtual Private Network
Because of the popularity of the Internet, as well as the cost of private leased lines, very large, and put many organizations create a virtual private network, and virtual private network. Traditionally, a provider of large organizations, and offices, one of the expensive cable connection has been leased to provide a direct connection between the two offices. Now, the solution is often more economical to provide two offices connected to the Internet. Then, using the Internet as a way to connect the two offices.
In such risk, of course, there is no privacy in this channel, it is difficult to provide a «other office did not get on the Internet to provide these resources, and to every person within the''resources.
Virtual Private Network and provides the ability to communicate between the two in such a way, it is like they are in leased line which connects directly look again. Meeting between them, despite the fact that the Internet, and this is in the private sector because it is encrypted connection, and contacts convenient, as everyone can see that they show to the world without the resources of all of the Interior.
The number of firewall vendors, including the ability to create products in their own virtual private network, directly with its core products, or attachment. If you need to connect multiple offices together, and maybe this is the best way to do so.

Have a secure network
It is important to remember that the firewall is the only point access network. Modem, if you can call them, can the attacker can easily sneak around and through the front door or your firewall is not. Just because there is no in front of castles and fortresses, your company needs in each protected entry.
Network Firewalls
As we saw in our discussion of the Internet and similar networks, which link the organization on the Internet provides a flow in both directions of traffic. This is clearly undesirable in many organizations, including the confidential information that is provided in many cases freely within the corporate network, a network TCP / IP, such as the Internet, which only works within the organization.
To ensure a degree of separation between the internal network of the Foundation and the Internet offer, and working as firewalls. A firewall is simply a set of components that together form a barrier between networks.
There are a number of conditions specific to firewalls and networks will be used in this section, so let us all to introduce.

Network security.
UUCP, like any other application, has compromised safety. Some of the highlights of his security, it is quite limited in what it can do, and therefore is more difficult to get to do something he should not, she has been there and most of the bugs its been discovered, analyzed and fixed, and because networks are made up UUCP links to other armies of the case, it is not possible to directly contact someone on Host B and take advantage of this connection to do something bad.
On the other hand, UUCP UUCP usually works with a user account system wide and password. Any system that has a connection to another UUCP must know the password for the account or nuucp uucp. Identification of a home beyond this point have always been little more than a matter of faith that the host is that it claims to be, and that connection is allowed at that time. Recently, there has been an additional layer of authentication, where both hosts must have the same number sequence, which is a number that is incremented each time a connection is established.
Therefore, if I run the host B, I know the password on the host uucp A. If so, I want to go home for C, I would have to conclude, identified as C, I hope at some point A, which will allow it, and try to guess the correct sequence number of the session. Even though this is not a small attack, it is considered very safe.

Mesh topology
Mesh topology is working on the concept of routes. In mesh topology, the message sent to the destination to take the shortest and easiest way to reach his destination. In the former star and bus topologies is usually sent out messages on any computer, especially in bus topology. But the message network topology can only travel in one direction ie clockwise or counterclockwise. Internet service to network topology and the message found its way to its destination. router work on finding ways and messages to reach them in their destinations.The topology where each device is connected to any other device is a full mesh topology, unlike the partial network in which each device is indirectly connected to other devices.
Tree Topology
And collected from different tree topology star topology in a bus. Topology tree integrate multiple star topologies together on a bus. Can not but that the devices are connected directly to the center of a bus tree, and the functions of each center as the root of a tree of network devices. Bus / star / hybrid combination to support the expansion in the future, computer networks, and much better than a bus or a star.
Star Topology
Computer network in the world, the most commonly used in network topology is star topology. Star topologies can be implemented at home, office or even in a building. All computers in the star topologies are connected to the central hub device, switch or router. The function of these devices is different. I refer to the details of each network device in each section of my website. Computers on a network are commonly associated with node, switch or router to the UTP Twisted Pair (UTP) or FTP Twisted Pair cables.
As compared with bus topology, a star network, the more complete anetwork equipment and cables. The failure of any node or cable in a star network, not across the network in comparison with bus topology.

Ring topology
In the ring network, each computer or device has two adjacent neighbors for communication. In a ring network, all communication messages traveling in the same directory where clockwise or counterclockwise. Any damage to the cable TV or any device can lead to destruction of the entire network. Ring topology now has become almost obsolete.
FDDI, Sonet, or Token Ring technology can be used to implement the technology of the ring. ring topology can be found in offices, schools or small buildings.

Bus topology
BUS topology uses a common base to connect all network devices on a network in a linear fashion. TV functions only as a means of communication common to all devices connected to this interface cable connector. Device that wishes to send a message broadcast to all devices connected to common cable, but only recipient actually accepts and processes this message.
Ethernet bus topologies are easy to install and require only very basic and the cable is generally used for the cable communication network. 10Base-2 and 10BaseT two popular types of Ethernet cables used in bus topology. In addition, the bus network operates with very small devices. Performance problems can arise in bus topology, if there are more than 12-15 teams added to the bus network. Moreover, if backbone cable fails, then the entire network becomes useless and there is no communication between all teams. Unlike the star topology, which, if a user is disconnected from a network, then there is an effect on other computers on the network

Network model client / server
In the sample client / server network team is playing a central role and is known as a server to all other computers on the network are known as clients. Access for all client computers server at one time for files, databases, documents, spreadsheets, Web pages, resources, campaign diver, printer, fax modem, CD-ROM and DVD / etc. In other words, everything depends on the client and the server is estimated if the server is not responding or crashes after the networking and communication between the client and server) calculates the stop.
To configure the network model of customer service, and then setting up a server first. Install Windows 2000 or Windows Server 2003 from CD-ROM on your computer to the server and domain. You can create a field through this command on the dcpromo run. "You can give this command once you install a server without problems. And after giving the dcpromo command will be asked to name one domain. All client computers use the same domain name only to become part of this area. This is installed server, Active Directory, DNS and other necessary things. There are step-by step wizard to walk and run for the remaining steps. Make sure you connect the network cable to the LAN card when the server is implemented Dcpromo.exe command.
When installed correctly the latest evidence on the server, and restart the server. You can create network users on the server computer, and the name / designation of network resources such as computers, printers.
