1. ARPANET was the first experimental computer network and precursor to the internet, developed in the 1960s by the US Defense Department's Advanced Research Projects Agency to enable resource sharing between computers. 2. The goals of computer networks include resource sharing between organizations with many computers located apart, high reliability through file replication across multiple machines, enabling interprocess communication between network users located geographically apart, and flexible access allowing files to be accessed and projects worked on from any computer in the network. 3. Computer networks have applications in business, communication, e-commerce, home use, electronic commerce, and for mobile users. They require hardware equipment, software, and cables/connectors.

ARPANET
ARPANET is stands for advanced research projects agency
network,experimental computer network that was the forerunner of
the internet. The advanced research rojects agency an aram of the us
defence department, funded the development of the advanced research
projets agency network in the data of 1960s.
GOALS OF COMPUTER NETWORK
1.Resource sharing:Many organization has a substantial number of
computers in operations which are located a
part.Example:Printer,fax,scanner etc.
2.High Reliability:If there are alternate sources of supply all files
could be replicated on two or more machines if one of them isnot due
to hardware failure,the other copy could be used.
3.Inter process communication:Network users located geographically
apart may converse in an inter active session through the network.
4.Flexiable access:Files can be accessed form any computer in the
network.The project can be began on one computer and finished on
another.
