Write a brief report on the evolution of computer networks: Computer networks networks are the logical result of evolution of computer and communication technologies. They represent particular case distributed computer systems and can be considered a medium for transmitting information over long distances. For later purposes, they implement data encoding and multiplexing methods developed and adopted in various communications systems. All network can be classified, based on geographical location

In a Distributed model, each site is self-sustained for the most part. While some connectivity to the primary datacenter is required, the remote site would host its own Email Server, manage its own backups, control its own Internet access, and host its own Shared Files. Application access may still rely on HQ, although many applications support this type of distributed model. The benefit of a Distributed model is that each site can ‘survive’ on its own. There is no Single Point of Failure in this
