We may have heard about network switches but there are some
confusion regarding them. Firstly, switches are devices that are used in
network connections and are thus used in local area network connections. In
other words a network switch is like a controller and it allows computers and
other devices to talk to each other smoothly.
Facts about
Network Switches
- Network switches do their operations at the Data Link Layer or the layer two of the OSI model of networking.
- In appearance they are similar to network hubs but are better able to handle network connections.
- They have the ability to check the data packets that pass through them and can send them to the required destinations appropriately.
- Network switches can conserve network bandwidth.
- Network switches are implemented for Ethernet connections.
- When switches are connected to each other it is called as called as daisy chaining.
- Network can save money for businesses and increase the productivity of an organization.
The Types of
Switches
Two types of switches are used:
- Unmanaged switches – it is very simple and can be used right out of the box. It‘s very easy to install and does not require much of a configuration. Generally used in homes, these types of switches have less amount of network capacity.
- Managed switches – these types of switches can be configured and they have greater amount of flexibility. These also have better capacity than unmanaged switches. A managed switch can be adjusted locally or in a remote way to allow for greater control.
The Use of
Network Switches
A switch is used to connect between two computers. It is a
centre point of multiple devices and through it data is transmitted from one
computer to another. Since, switches are better able to handle data connections
they are used at homes, in offices and other places where network connectivity
is required.
Using a
Switch in a Network
To use a switch in a network, one needs to determine the
speed of connection and the number of ports. Then the switch should be
connected using an IP address. Next, the cable from the uplink port is to be
connected to the rest of the network via an Ethernet cable. After that the
Ethernet cables are connected from the computers to the ports of the switches.
Finally, the settings are hard coded if required. As the computers are switched
on they will automatically adjust to the settings of the switch.
