WHAT IS A SWITCH?
He switch A switch is a digital logic device for interconnecting equipment that works at the data link layer of the OSI model.
He switch It is a device used to connect networked equipment, forming a local area network (LAN), and is responsible for the interconnection of wired devices, which follow the technical specifications of the Ethernet standard.
Interconnection devices consist of two areas of operation in telematics networks;
Routers; responsible for the interconnection of networks
Switches; They are responsible for interconnecting equipment within the same network. They constitute local area networks or LANs.
He switch It is, undoubtedly, one of the devices with the highest level of scalability. There are switches four-port with basic functions, to cover small interconnection needs and we can also find switches with hundreds of ports with very advanced features and capabilities.
Types of switches
We can find different types of switches:
- Desktop Switches
It is the switch more basic and is usually used in the home or in small businesses, for the interconnection of a few devices.
- Unmanaged Edge Switches
Are switches which are used to create small, medium-performance networks. Similar to the switches desktop but with more ports and more mounting options.
- Managed edge switches
This type is used to connect user equipment in medium and large networks, and is located at the lowest hierarchical level. It is necessary that these switches offer advanced configuration and management features.
- Mid-range trunk switches
These switches are designed to form the backbone of a medium-sized network, providing high performance and advanced features.
- High-performance trunk switches
In addition to their high performance, they are characterized by their high modularity. They are used in large corporate or campus networks, among other applications.
The switches They are central devices in many networks, especially local area networks. The great flexibility of Ethernet, as the underlying technology of these networks, is key to their development. switches, This has allowed for enormous flexibility in establishing the configurations and topologies of Ethernet-based networks (virtually 100% of the world's wired LANs), ranging from small home networks with a few devices to large corporate networks. Thanks to such a wide range of models of switches, the needs of all possible types of networks that may exist can be met.
He switch It has the ability to learn and store, on its own, network addresses of devices reachable through its ports. Unlike a hub or concentrator, the switch It allows information directed to a device to go from a source port to a destination port.
He switch It is a purpose-built device specifically designed to solve network performance problems caused by low bandwidth and bottlenecks. It can increase bandwidth, speed up packet forwarding, reduce latency, and lower the cost per port.
