Networking

                                                                     Networking
Computer networking is the engineering discipline concerned with the communication between computer systems or devices. This is important for a variety of reasons, many of which already have been mentioned above. A computer network is the interconnection of computing devices in order to share data and is built with a combination of computer hardware and software. 
So you want to set up a computer network. Right here, we have two of my computers  Macbook and PC here.And they both have Ethernet ports but where do connect them to. What I  need is something like this a router. Router has a bunch of ports in  the back that I can  connect to  multiple computers, and it also works wireless. A router, you can connect Macs and PCs on combined network. 

      First, Neworking devices that filter that traffic are called connectivity devices and there are several different types.

          Bridge  is connectivity device that forwards data based on a physical address and operate at the Network Access layer in the TCP/IP.

           Hub typically do not filter data but instead retransmit incoming data packets or to all ports.

           Routers are an essential part of the any layer TCP/IP that would be the IP address.

           Switch,simplified is smarter version to all ports.

      Second, networking types.this part is about most famous connection type and their adventages

   1.      WAN (wide area network )

Much larger than other connection types , example : whole world and it includes of the LANs and WAN

2.      MAN (metropolitian area network)

MANs connect two or more local area networks or campus area networks by connecting routers, switches and hubs (will be defined in hardware section), within the area of a single town or city.It includes mini network such as  LAN and PAN

3.      LAN (local area network )

A LAN may be either wired or wireless and is a computer network that covers a fairly small area, such as a home, office, or small group of buildings, such as a library or airport.It shows higher speed than other for sharing data resources

4.      PAN (personal area network )

A PAN is a computer network used to connect devices that are close to someone's person.Its advantage is for example you can share photos computer devices ,watch your TV from your home

5.      PN (private network )

With this network any person or company connect to each other without internet and without easily their datas of internet.

       Next,  think of a topology network's virtual shape in structure and computers are a home network be arranges in a circle in a family room other rooms. Network topologies are categorized into the following basic types.bus,ring,star,tree,wesh topologies. Topology remains an important part of network design they .You can probably build a home or small business computer network without understanding the differance between a bus design and star design  but becoming familiar with the standart topologies gives you a better understanding of impotant networking concept like hubs,broadcats and routers.

       Finally, Computer communication, it seems, will become a much more useful networking tool when large numbers of people with similar interests acquire access to the technology. Though it can expedite the formation of new interpersonal networks by overcoming the space and time barriers faced by traditional networking techniques, it still requires a great deal of concentrated effort and resources to get the people to use it. This problem should become increasingly minimized over the coming years as the technological innovations become more diffused throughout society.
