VLAN stands for Virtual LAN. It is called as such because you are essentially creating "virtual" networks on the same physical piece of hardware. Imagine a network switch with 20 ports. You could assign the first 5 to VLAN1, the next to VLAN2, and so on. You would end up with 4 segregated networks, but on the same physical switch. The virtual in VLAN is referring to the fact that there is nothing phsically separating the ports on the switch, it is done "virtually".

What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
How does a virtual lAN allow devices to be grouped?
Devices in the same VLAN are part of the same subnet, or "group". (The fact of belonging to one VLAN or another is, to a certain degree, independent of the physical location, thus the name "virtual".)Devices in the same VLAN are part of the same subnet, or "group".

What is pvid?
A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.
What is true about vlan?
VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined as Virtual Local Area Network.
What is virtual trunking protocol VTP?
Virtual Trunking Protocol (VTP) is a Cisco proprietary protocol used in switched networks to manage VLAN configurations across multiple switches. It allows switches to share VLAN information, ensuring consistency in VLAN configuration throughout the network. VTP reduces the need for manual VLAN configuration on each switch, thereby simplifying network management and reducing the risk of errors. It operates in different modes, including server, client, and transparent, each with specific roles in VLAN information dissemination.
What is vlan?
VLAN is Virtual Local area network and it is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. VLANs are configured through software rather than hardware, which makes them extremely flexible.
What do switches create when they group a number of ports into broadcast domain?
this would be called virtual local area connection or a vlan
What is the purpose of the switch command switch port access vlan 99?
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
What is the definition of VLAN?
Virtual local-area networks (VLANs) are a switching technology used to improve network performance by separating large broadcast domains into smaller ones.(quote from CCNA 640-802 Exam Topics)The abbreviation VLAN stands for "Virtual Local Area Network". A VLAN is used to segment a physical network into several logical networks which do not interfere with eachother, even though the data might be traveling on the same physical wires.
What is the basis for membership in a vlan?
Membership in a VLAN (Virtual Local Area Network) is typically based on factors such as port assignments on a switch, which can be configured to associate specific ports with designated VLANs. Additionally, VLAN membership can be determined by MAC address filtering or through protocols like GVRP (GARP VLAN Registration Protocol). This segmentation allows for improved network management, security, and traffic isolation within a larger network.
What is traditional inter vlan routing?
Traditional inter-VLAN routing involves using a router to enable communication between different VLANs (Virtual Local Area Networks). Each VLAN is assigned its own subnet, and the router interfaces with each VLAN through sub-interfaces or physical interfaces. This method allows for the separation of broadcast domains while facilitating inter-VLAN traffic, enhancing network performance and security. Typically, this approach requires a router or a Layer 3 switch to manage the routing process.
Is there a program that can make a LAN connection through the internet?
The type of network your asking about is called a VPN (Virtual Private Network) or a VLAN (Virtual LAN). A VLAN acts like an ordinary LAN, but connected devices don't have to be physically connected to the same segment. LogMeIn Hamachi lets you setup a virtual LAN connection on both PCs and Macs through the internet. The software is free for non-commercial use, never expires, and will let you set up your virtual LAN connection in less then 10 minutes.
