What is a LAN Segment?
Introduction
A LAN segment is a group of devices (i.e., servers, workstations) that are connected to each other via Ethernet cables. These devices communicate with one another through the use of CSMA/CD protocol and Ethernet packets.
A LAN segment can also be referred to as an Ethernet local area network (LAN). The term “segment” refers to a part or division of a greater whole which in this case would be the entire LAN.
A LAN segment does not have to be confined within a certain shape or boundary. This is contrary to what many people think about the term “segment.” Instead, it can exist in any area where there are several stops along with an interconnected network of nodes. For example, LAN segments may span across major cities or even include different countries.
What is a LAN Segment?
A LAN segment refers to a part of a computer network that is created by connecting two or more devices via a physical cable. In this scenario, the LAN segment will be one section of a larger network. An example of a LAN segment would be joining three devices using an Ethernet cable which creates a tiny local area network within a home.
The devices that are connecting into the LAN segment can then send information to one another, such as taking turns when downloading a file from the internet. The bandwidth of the devices in regards to how much data they can transfer varies depending on what type of cable is being used and how much traffic is currently flowing through the network.
A LAN segment is a physical or logical subnet used for local area network (LAN) communication in computer networks. A LAN connects computers and devices within the same space. LAN segments are defined by technology and may operate at different speeds, depending on the medium used to implement them.
How does it work?
LAN Segments are a group of computers that communicate with each other over a series of cables. They connect to a shared resource, such as a hub or switch, which can link to other networks.
When you plug into your home network, you’re connecting to the long list of cables that transfer data between devices within your house. LAN Segments are very similar in function to how a WiFi signal works, but use cabling instead of wireless connections. Theoretically, LAN Segments can connect to other networks (such as the internet) through hubs or switches. However, this is not a standard practice due to the possible security issues involved.
LAN Segments are an important part of daily life when it comes to computers. Many modern devices have multiple ways to connect with LAN Segments, including wired and wireless connections. Network admins need to understand how these connections work before rolling out a new network or device into their workplace.
What are the benefits of having a LAN segment?
The benefits of having a LAN segment include:
– The elimination/minimization of any latency (lag) in the network;
– The ability to replicate data at all locations;
– Redundancy in communications; and
– The simplification of firewall configurations.
What are the disadvantages of having a LAN segment?
The disadvantages of a LAN segment are as follows:
-A complex network
-Inability to recover from downtime
-Limited geographic coverage
-Limits on the number of nodes within a network
How many types of LAN segments are there?
There are four types of LAN Segments:
1) Collapsed LAN Segment- where all devices are on one switch. This is not considered a LAN Segment since the traffic for all devices flows through one switch, meaning that it would be just as fast to use just one device.
2) Basic LAN Segment- there are at least two switches with no VLANs or routing between them. The traffic from each switch flows directly to all attached devices. Devices attached to each switch can communicate with devices attached to the other switch.
3) Extended LAN Segment- there are at least two switches, and a router between them. The traffic from each switch goes through the router to reach all attached devices. Devices attached to each switch can communicate with devices attached to the other switch.
4) Hybrid LAN Segment- there are at least two switches. VLANs have been configured on the switches, and a router separates them. Devices attached to each switch can not communicate directly with each other but can communicate through the router.
Conclusion
A LAN segment is a group of devices on the same network. When you create one, it will be typically made up of two or more Ethernet ports that are physically close together and connected to each other. A common use for this type of setup is in an office environment where multiple employees share the same floor space with their cubicles being no further than 10 feet apart. The benefits include increased speed due to less electrical interference, reduced power consumption by eliminating wasted energy, and better security because all data can only go from point “A” to point “B” which makes hacking much harder. The disadvantages are price as segments require switches inside them so they cost more upfront but save money over time if used properly; also there may not be enough bandwidth for each device on the network to have its own dedicated line if there are too many.
