Networking

In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hun, bridge, switch, router and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies and procedures related to the network.

First, 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. Now , a router has a bunch of ports in  the back that I can             connect to  multiple computers, and it also works wireless.So I can connect them with cables. A         router, you can connect Macs and PCs on combined network.

        Then, These networking devices that filter traffic are called connectivity devices and they are         several different types.

   Bridge – bridge is connectivity device that forward data based  on physical address and operate at      the network access layer in the TCP/IP

   Hub – Hub is typically do not filter data , but instead incoming data packets or frames to all parts.

   Switch – A switch simplified is a smarter version of a hub

   Router – Routers are an essential part of any TCP/IP network that would be the IP addresses.

      Next, Networking types - This lesson is about most famous connection type and advantages

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.

          So, 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

        After that, Networking problem

First step – Nerwork adapter is properly installed and directed by the computer with no conflies.

Second – wired network verify that the network cable is properly connected and make sure the LED’s next to the jack are properly illuminated.

Wireless network if you’re using laptop with a wireless network , just look for the laptops  WiFi botton and make sure it is turned on.

       Conclusion, Networking is a process that fosters the exchange of information and ideas among individuals or groups that share common interests.When your networking is driven by shared interests, it will feel more authentic. As you can see there are many different types of computer networks in the world today. The options range from the wired to wireless to a network that only extend to a 20-30 foot radius to a network that could span accross an entire nation. Networks enable you to print an file when you are in a completely different room from your printer or to email a freind or family member in another state. The technology we have today is truly amazing and will only continue to grow and connect people from all over the world. So next time you e-mail a long-lost freind who is miles away you can thank computer networking for making it possible.
