Switches are network equipment and are used to distribute and redistribute data in the internal network of users. This device is needed to connect the required number of personal computers and terminals to a single system. There are home (small) and industrial switches. They differ in the number of ports, case strength, reliability in dusty environments, and resistance to vibrations. To choose the right used switch, you need to understand their parameters.
Switch characteristics
The switch works according to the following algorithm: it has a built-in table with the addresses of connected devices. It is filled in on a self-learning basis by scanning devices and running them through a given program. After that, the switch compares the addresses and data in the table. Unlike a router, a switch simply distributes data within the system, while a router receives Internet traffic from an ISP and distributes it to the internal network.
The main characteristics include:
- Number of ports
- Interfaces
- Manageability
- Port speed
The number of ports varies from 8 to 52. In large systems, devices can be grouped together to increase the number of network users. The PoE switch is used to connect video surveillance, webcams, or IP telephony.
The Fast Ethernet interface provides speeds of up to 100 Mbps and operates on twisted-pair cable. Gigabit Ethernet is a newer technology that transmits data at a speed of 1000 Mbps over fiber.
There are managed and unmanaged switches. For home networks, it is advisable to choose an unmanaged switch - the connection is automatic without the need for administration. For business, it's better to buy a managed switch. Such models allow you to configure, manage traffic, monitor, and have access control mechanisms.
