In the previous article, it was discussed that network monitoring plays an important role in maintaining the performance of a telecommunications company network device. The client can feel satisfied with the services provided because the company can provide full service without interruption or high availability. Client satisfaction greatly affects a company’s brand image. If the client feels satisfaction, the client will report good things about the company.

You might be wondering, what kind of network devices should be monitored? Network devices play a role in connecting one computer to another. When the computer is connected, the computer can send and receive messages or information.

There are many types of network devices. Even though they have different functions and roles, these network devices support each other’s performance. Network monitoring is needed to be able to see the performance of each network. If there is one device that is not connected in a computer network, the other device will be interrupted and not functioning.

There are several different network devices. But in this article, we will discuss the five devices first. The following are the network devices:

1. Router

The router is a network device that functions to connect two or more networks. The router connects the network with star, bus and ring topologies. Thanks to the two network router can exchange information and data.
Routers are used in the TCIP / IP / IP router network protocol. In addition, the router is an access server, a device that can make connections that connect LANs to telecommunications services. This router is called DSL (Digital Subscriber Line) Router.

2. Wireless Card

This device can connect a computer with other computers using Wi-Fi without using a cable. Nowadays, there are many laptops that have wireless cards in it, so there is no need to buy a wireless card separately. Unlike laptops, computer users must buy a wireless card separately to connect to Wi-Fi.

3. LAN Card

The LAN Card can also connect one computer to another. The difference is that the LAN card must connect the computers using a cable. Lan Card will change the flow of data from a parallel form to a serial form, then the data will be transmitted via UTP cable.

4. Bridge

This device can expand the network so that it can be used by other devices in a wide range. The bridge functions to forward data, dividing the network into several networks. This makes the network reach wide. The bridge has an internal bridge table that functions to determine which segments must be filtered.

5. Hub

The hub functions are to divide the server into other networks. The Hub will copy data from the source that is connected to the port on the hub. If in a building there are 10 computers connected to the Hub and have one data source computer, the Hub will share the data with the connected device. However, if the hub experiences transmission disruption to other networks it will be hampered.

It turns out that the network device is so various types and functions. However, these five devices have similarities that they can connect computers to one another so that they can share information and data. In addition to the five network devices already mentioned there are still other network devices that also have different roles. These devices (switches, access points, repeaters, repeaters, nic, and connectors) will be discussed in the next article.

If you have a problem with your network device, do not hesitate to consult with Ketitik. Ketitik also has product monitoring tools to help network engineers carry out their duties. Please read our Netmonk article to get to know an Indonesian network monitoring.
