What is a network switch?
What is a Cisco switch? Cisco network switch is an important and indispensable device in today's telecommunications network systems. Cisco network switches are also known by many different names such as switches or network switches.

Cisco Switches operate at Layer 2 of the OSI model. Cisco network switches have the ability to connect multiple segments together based on the number of Cisco switches. The switch also learns network information through the packets it receives from computers on a network. From this information the Cisco Switch panel will be constructed and packets will arrive at the correct address.
Switches have two outstanding features: transferring frames from the destination source and building Cisco Switch boards.
Cisco switches can be directly connected to source and destination computers as well as other switch devices that share the same protocol.

Main functions of Cisco Ethernet Switch
Cisco switches can be said to be relatively similar to Hub and some of the differences in the outstanding functionality of this device should be mentioned such as:
-Switch Cisco chooses the path to send the Frame to the destination, operating in Layer 2, the OSI model makes the LAN work better.
Cisco learns the source MAC address in the Frame to identify connections to its port.
Cisco establishes a virtual circuit between two respective ports without affecting the traffic on the ports.

The switch separates the traffic on each segment of the network
The Cisco Ethernet Switch divides the network into microscopic units called microsegment. Such segments allow users on many different segments to send data at the same time without slowing down network operations.
By splitting the network, it reduces the number of users and devices sharing the same bandwidth. Each segment is a separate collision domain. The Cisco switch restricts traffic to only forward packets to the correct port based on the Layer 2 MAC address.
Increase the amount of bandwidth for the user
Increase the amount of bandwidth available per user by creating a smaller collision domain. Cisco Switches ensure to provide more bandwidth to users by creating smaller collision domains.
The switch divides the LAN into several segments, and each of these segments is a separate connection that resembles a 100 Mbps private lane. Each server can host a separate 100 Mbps connection.
In today's network systems, Cisco Fast Ethernet Switch is used as the backbone for LANs, while Cisco Ethernet Switch, Ethernet Hub or Fast Ethernet Hub are used to connect down computers. As new applications such as multimedia communications, video conferencing ... become more and more common, each computer will have a separate 100 Mbps connection to the Cisco Switch.
-Switch Cisco makes the hosts can operate in full duplex mode, doing many jobs at the same time.
-Reduce the error rate in the frame. Frame will be checked for errors. Good packets when received are stored before being sent using store-and-forward technology.
Cisco Switches can limit the transmitted traffic to a certain threshold level.
Genuine Cisco switches with outstanding features are a popular choice for many customers.
