VLAN vs LAN: Difference and Comparison

A local area network is a cluster of network endpoints that communicate with one another. Similarly, a VLAN is a sort of LAN that expands on the possibilities of a conventional LAN.

The primary need for adopting VLAN is network segmentation. To reduce congestion and strain, connections are separated into workstations inside a LAN.

Formerly, basic LAN was restricted in its powers and caused network latency. Virtual LANs can only be built using shifts or spans, whereas LAN hubs utilize switches and modems.

Key Takeaways

  1. VLANs (Virtual Local Area Networks) enable network segmentation, improving security and reducing network congestion, while LANs (Local Area Networks) are physical networks connecting devices within a limited area.
  2. VLANs are created and managed using software, whereas LANs require physical hardware such as switches and routers.
  3. VLANs can span multiple LANs, enabling geographically separated devices to communicate as if they were on the same local network.


The difference between VLAN and LAN is that VLAN is a technology that is designed to improve the productivity of Local Area Networks. VLAN operates on numerous broadcast realms, allowing it to unite end stations with identical requirements regardless of physical proximity, which is not feasible with LAN. A LAN, on the other hand, is a collection of network technology that would allow transmission between linked devices. The LAN operates on a solitary broadcast realm.

VLAN is a form of LAN that enhances the functionality of a static LAN. VLAN is a conceptual split of LAN that allows for the creation of many LAN portions in a single frequency independent of the device’s geographical place.

As a result, personnel can divide a LAN into distinct base stations by using a fiber converter. Customers on various levels of similar structures or other buildings can now access the equivalent LAN since the boundaries are reasonable.

A LAN may connect numerous machines in one area to transfer data between them. It can consist of two machines in a workplace or numerous in a firm, all accessing a network that is not accessible to the outside world.

When one person transmits a message, everyone else may receive it, which is referred to as a unified broadcast system.

Furthermore, LAN may implement features such as record keeping, printer collaboration, and joint committee scheduling, which will assist to increase overall effectiveness.

What is VLAN?

VLAN is a theoretical split of the LAN in which numerous LAN components are generated under a unified bandwidth. The advantage of Simulated LAN is that the LAN sections built in the LAN may be stretched and expanded as needed.

More throughput is generated by dividing a single routing zone. It reduces the need to deploy several switches for an institution’s many partitions.

VLAN must adopt a hierarchical network referencing strategy that allows IP domains to be provided to network segments or VLANs comprehensively.

VLAN is implemented via adapters, with a single VLAN assigned to each specific port. Broadcasts can be shared across devices in the same VLAN, but not between ports in separate VLANs.

It also adds protection by limiting the transmission to every socket on the converter and splitting a single distribution into many broadcasts.

VLAN provides more flexibility because the terminals can also swap if necessary. It saves money by eliminating the requirement for costly switches to divide a network’s nodes.

Static VLAN enrolment is a sort of VLAN establishment in which the VLAN gets dynamically allocated to the channel.

This stable arrangement is regarded to have been the safest approach to create a VLAN even though it does not alter unless and until the traffic supervisor modifies it.


What is LAN?

LAN; Local Area Network is a collection of computers configured to interact with one another over a small territorial location. It might be a structure, an office, a university, or anything else.

Because it uses low-cost equipment and computing gear, it is the cheapest form of network. It allows users to share documents, software programs, webcams, projectors, and other assets and content.

It can give resources virtually even if they are not available. The central management of a LAN is in charge of it.

As a gateway to the connection, LAN necessitates several fundamental aspects for its functioning. These components encompass computers and electronic gadgets that serve as network nodes to transmit and receive data.

Interconnections make it easier for data to transfer from one point to another. Interconnection includes NICs and transport carriers.

The Network Adapter Card’s role is to transform data into a format that can be transferred over the LAN. The network medium employed to transfer signals is connectors and cellular technology.

Centers, switches, and firewalls are LAN network equipment. These devices serve as the connecting device between integrating devices or LAN sections.

The router acts at the protocol stack, whereas the hub and toggle are layer 2 hardware. The Protocols govern the data transfer across the LAN. There are two kinds of LANs: wired LANs and cordless LANs.

Wired LAN comprises 10BaseT, ultrafast, and Fiber Channel, among other protocols.

Main Differences Between VLAN and LAN

  1. Numerous broadcast zones can be implemented on a single media via VLAN, and the package can be dispatched to the appropriate LAN segment. In contrast, because LAN has a single broadcast scope, each package is disseminated to all connections excluding the transmitting device.
  2. VLAN is more adaptable and expandable, since new users may be included and withdrawn as needed and implemented in the appropriate LAN section. In comparison to VLAN, LAN is less scalable and versatile.
  3. VLAN is simple to debug and administer since it employs specialized technologies. LAN performance is ordinary as opposed to VLAN, which provides more accuracy and precision.
  4. VLAN-specific protocols, such as ISL and VPN Trunk Interface, are used in network mechanisms. Whereas Standard LAN interfaces such as ballot medallion and FDDI are used in LAN.
  5. VLAN is a cost-effective management technique at lesser investment. However, setting up a LAN is an expensive setup
