Understanding VLANs, along with their functions and types, LAN network is a collection of computer devices with network devices that are connected to each other and can communicate with each other in a room or building. LAN can also be interpreted as a small-scale computer network usually used in a company, government, hospital.
LAN networks are widely used in applying a computer network because it is easy to install and the devices used are simple and affordable.
The things that are needed in building a LAN network are:
Hardware
Hardware is a computer device that is in the form of objects or can be called hardware, for a LAN network the hardware needed is..
1. Server Computer
The server computer is needed as a service provider that will serve the client computer and which will be the center of the network control settings that we will create.
2. Client Computer
On a LAN network, a client computer is needed as the main device to communicate with each other, a client computer is a computer that will receive services from a server computer that has been provided previously.
3. Network Interface Card (NIC).
NIC is a network device that serves as an interface from the network cable to the computer. There are 2 types of NIC on a computer network.
Physical NIC
Is a physical NIC or hardware that is used on a computer to connect to a network, usually this NIC is located on the motherboard with a certain type of port such as an RJ-45 port and is located on the back panel of a personal computer motherboard.
Logical NIC
A card that does not have a physical form or hardware but a NIC that uses software as a virtual NIC.
4. UTP Cable or Unheld Twister Pair
This type of UTP cable is used in LAN networks with a STAR topology, as a data communication path on a network, or as a transmission medium from one computer to another.
5. Switch or Hub
The switch is used as a concentrator that connects all network devices and becomes a data transmission center. As a liaison from one network device to another network device. Like connecting one computer to another, connecting computers
Software
Software is software that is used to connect hardware to the system or with other software. Software can identify programs that exist on the computer, and can translate commands that are in machine language form.
On a LAN network there are 2 types of software, namely:
1. Operating System
Operating system
To build a LAN network, the operating system is a must. The server that we use must of course have an operating system installed that suits our needs. In setting up a LAN network, the operating system commonly used is the Windows or Linux operating system.
Client Operating System
The operating system used is an operating system that is simpler than the operating system used by the server. Most users or network clients use Windows operating system.
Definition of VLAN, along with its functions and types
Definition of VLAN
VLAN stands for Virtual Local Area Network or a limited virtual local area network.
A VLAN is a collection of network equipment such as computers, printers, or servers that are connected to each other and are located in adjacent areas. In a device these are connected logically and not because they are physically close together. Without all data traffic between departments will be mixed in the network.
Also Read VLAN id is
Use of VLANs
To organize and separate data traffic so that it doesn't get mixed up and to speed up the network even more, we can create VLANs in each department. We can create VLANs using a manageable switch that provides features for administrators to make VLAN settings.
In implementing a VLAN, data traffic between departments will be separated on the network even though the computers are on the same cable line and switch. We set this VLAN on a switch by allocating ports according to the VLAN we want to create.
The VLAN function is
1. Improve network performance.
On the VLAN network the system works more simply so that data traffic can run effectively and efficiently.
2. Using Switch as a liaison so that it is easy to process.
VLAN only uses a switch to unite several LANs, for example, a network at school has a LAN in every room with a VLAN system, so we can make some of these LANs into
One network. By uniting several LANs so that these LAN LANs can communicate with each other with VLAN Networks.

3. Easier Network Administration
VLAN networks are easier to control because some LANs only have one central server. So that from some of these LANs it is only controlled by one server.
4. Better security
Because the VLAN only has one server, it is easier to control security, and also like the creation of a firewall, broadcast settings, and including domain settings.
Types of VLANs
- Based on the Default VLAN Switch, the condition of all ports on the switch has not been configured.
- Data VLAN, Configured Specifically For The Data Graph Used By The User.
- Voip VLAN, Dedicated to Audio Communication, Compared to Data Communication.
- VLAN Native, Designed To Support Switches That Don't Support Paging.
- VLAN Management, Used For Management Purposes.
Thus the understanding of VLANs, along with their functions and types, you can also learn about VLAN Trunking, and what VLANs are for. Hopefully this article can help, and useful for all of us.
