Major data network types

The three types of the data networks are:

1. Local Area Network (LAN)

2. Wide Area Network (WAN)

3. Internet, Intranet and Extranet

1. Local Area Network (LAN): A LAN is a computer network that interconnects computers in a limited area, such as a home, computer laboratory, school or office building, which use network media. LAN shares network services, such as e-mails, databases and application services, by connecting various workstations and various servers via a set of LAN protocols and various access methods.
