The star topology is the most common in contemporary times. Wireless LAN (WLAN) also has its topologies: independent basic service set (IBSS, an ad-hoc network) where each node connects directly to each other (this is also standardized as Wi-Fi Direct), or basic service set (BSS, an infrastructure network that uses an wireless access point). [6]
A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). [ 2 ] [ 3 ] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network .
This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
Similar to wired network virtualization, in which physical infrastructure owned by one or more providers can be shared among multiple service providers, wireless network virtualization needs the physical wireless infrastructure and radio resources to be abstracted and isolated to a number of virtual resources, which then can be offered to ...
In computer networking, a wireless access point (WAP) (also just access point (AP)) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a switch or router , but in a wireless router it can also be an integral ...
A PAN may be carried over wired interfaces such as USB, but is predominantly carried wirelessly, also called a wireless personal area network (WPAN). A PAN is wirelessly carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth, NearLink or Zigbee. The reach of a WPAN varies from a few ...
An example of a simple home network. Home networks may use either wired or wireless connectivity methods that are found and standardized on local area networks or personal area networks. One of the most common ways of creating a home network is by using wireless radio signal technology; the 802.11 network as certified by the IEEE.
A backbone or core network is a part of a computer network which interconnects networks, providing a path for the exchange of information between different LANs or subnetworks. [1] A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas.
