Wide area networks (WAN) Metropolitan area networks (MAN) Local area networks (LAN) There are three features that differentiate MANs from LANs or WANs: The area of the network size is between LANs and WANs. The MAN will have a physical area between 5 and 50 km in diameter. [2] MANs do not generally belong to a single organization.
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, [ 1 ] [ 2 ] [ 3 ] for sharing data and devices between each other, including Internet access .
The defining characteristics of a LAN, in contrast to a WAN, include higher data transfer rates, limited geographic range, and lack of reliance on leased lines to provide connectivity. [ citation needed ] Current Ethernet or other IEEE 802.3 LAN technologies operate at data transfer rates up to and in excess of 100 Gbit/s , [ 67 ] standardized ...
Common types include local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN). Local area networks have the coverage of a small geographic area, such as a school, residence, building, or company. [4] [5] [6] Metropolitan area networks cover a larger area, such as a city or state. Wide area networks provide ...
Unlike IAN, LAN interconnects computers in a limited area, such as a home, a school, a computer laboratory, or an office building. The WAN also differs from the IAN because it is a network that covers a broad area, such as any telecommunications network that links across metropolitan , regional, or national boundaries, using private or public ...
There are some similarities between SD-WAN and WAN optimization, the name given to the collection of techniques used to increase data-transfer efficiencies across WANs. The goal of each is to accelerate application delivery between branch offices and data centers, but SD-WAN technology focuses additionally on cost savings and efficiency ...
