Describe the five types of networks and how they differ based on organizational requirements, interconnected devices and geographical area served

The networks we will be describing will be by their scope and scale. The first network we will mention is the area network: Common examples of area network types are:

LAN - Local Area Network. A LAN connects network devices over a relatively short distance. In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring.
WLAN - Wireless Local Area Network. AWLAN provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling.
WAN - Wide Area Network. , a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.
Other Types of Area Networks
• Metropolitan Area Network - a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation.
• Campus Area Network - a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.
• Storage Area Network - connects servers to data storage devices through a technology like Fibre Channel.

• Describe the uses of directory services, DNS, DHCP, network management and remote access services.
