Difference between LAN and VLAN

LAN stands for Local Area Network is a group of network devices which allow the communication between connected devices. 

Advantages

• Low-cost
• Sharing is easy
• Easy configuration

Disadvantages-

• Issues in security
• Covers limited area
• Infected to viruses easily.

VLAN

VLAN stands for Virtual Local Area Network which is used to enhance the performance of LANs (Local Area Networks). 

Advantages-

• Data transmission is fast.
• It has good performance.
• Less network administration

Disadvantages-

• Infected to viruses easily
• Additional router is required.
• Packets are more likely to leak from one VLAN to another VLAN.

Difference between LAN and VLAN-

 Differences between LAN and VLAN are as follows:

LAN	VLAN
LAN stands for Local Area Network.	VLAN stands for Virtual Local Area Network.
It work on a single broadcast domain.	It works on multiple broadcast domain.
It was developed in late 1970s.	It was developed in 2003.
The cost of Local Area Network is high.	The cost of a Virtual Local Area Network is less.
The latency of Local Area Network is high.	The latency of a Virtual Local Area Network is low.
The devices which are used in LAN are: Hubs, Routers and switch.	The devices which are used in VLAN are: Bridges and switch.
They use standard Ethernet protocols.	They used ISP and VTP standard protocols.
Connection ranges up to 2 miles.	Connection has a similar range.
In local area network, the Packet is advertised to each device.	In virtual local area network, packet is send to specific broadcast domain.
Local area network is less efficient than virtual local area network.	Virtual local area network is greater efficient than local area network.
No information is needed to use LAN.	User should know multiple commands to configure VLAN.
There are no types in LAN.	Default VLAN, Data VLAN, Native VLAN, Management VLAN and voice VLAN are the types of VLAN.
