Networking
In information technology,
networking is the construction, design, and use of a network, including the
physical (cabling, hub, 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.
