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 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.
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.
How do you connect computers on separate VLAN?
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
how are packets assigned to the VLAN?
VLAN: How are packets distributed with respect to the different classifications?
Why would packets from the router or hosts fail when trying to reach the switch management interfaces if the native VLAN were left in default?
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
