  What is Network?

                  " Network is combinations of  computers, hardware devices,physical media,network devices and computer soft wares interlinked together for allow them to communicate with each others through the communication path ways."

 Why Networks?         

Now a day’s in the world the usage of network is growing efficiently.i hope this is very foolish question. There are so many features we are getting from networks.The main objective of the network is 'Resource Sharing' and 'Centralized Management'.
Sharing of Resources means share the data,applications,soft wares and hard wares such as printers,faxes ...etc along the nodes.
Centralized Management is managing group of computers,hardware devices,peoples,their information's, into single network segment.e.g, FTP Service,ADD Service,DHCP Service etc... 

Milestones in the history of Networking?

 Initially computers were mostly used for research and national defense purposes.Data networks designed exclusively for computing environments followed the introduction of business computing in the 1950s.

In 1960s—The first large-scale commercial computer network is created for an Airline Reservation Application and the Advanced Research Projects Agency Network (ARPANET) successfully links computers developed by different manufacturers, forming what is later described as the origin of today’s Internet.
In 1970s—A networking technology for minicomputers called Ethernet is developed.

In 1980s—The increase in the number of stand-alone desktop microcomputers within organizations In encourages widespread adoption of local area networks (LANs).

In 1990s—Web-based Internet resources are introduced on a global scale.

In 2000s—Improved networks provides the access to connect to with a network from any where in the world.That is World Wide Web.to-days Internet         

Aspects of Network?

     There are two aspects for setting up a network
           The first one is the physical media which is used for connecting hardware devices into a single network segment.The media can be Cables,Wi-Fi,Bluetooth,Infrared...etc.
         The Second one is the software or Firm Ware which is installed on the device should allow them to communicate with each others.

ADVANTAGES OF PERSONAL AREA NETWORK

Advantages of Personal Area Network:
Portable:
            This is portable type of network that is if a person moving from one place he can carry his portable devices such as laptops,mobile phones,personal digital assistant...etc. So he can establish his network wherever he want without any wire by using wireless technology.

Security:
           Every information which are stored in the devices which are shared via network with authorized peoples only. So there is secure file transfer between devices.

Wearable Computing:
           This is the basic concept for wearable computing.It gives royal look and which makes work simple.

DISADDVANTAGES OF HOME AREA NETWORK

`
Lack of Wifi Password:
                   If the wifi password is easily guessed by others then any body on within the range can  stole Internet access and resources on the network.

Wifi-Microwaves:
                   Wireless devices uses microwave as a medium for communication.This microwave signals are will affect specially affect brains.It is not good for health.

Expensive:
                    The devices which are used for communication are should be capable to to access Internet which my expensive.etc...smart TV,laptops,smart phones...

Internet slow:
                    When multiple peoples accessing Internet with same share point then Internet speed will be shared to all users with equivalent speed.If one person is downloading a large file from Internet then it will slow down the speed for all other uses.
