Types of Network Devices (1)

In the previous article, we discussed that network monitoring plays an important role in maintaining the performance of a telecommunications company’s network equipment. Clients can be satisfied with the services provided because the company can provide full service without interruption or high availability. Client satisfaction greatly affects the company’s brand image. If the client is satisfied, the client will tell good things about the company.

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

There are many types of network devices. Although they have different functions and roles, these network devices support each other’s performance. Network monitoring is required to be able to see the performance of each network. If there is one device that is not connected in a computer network, other devices will be disrupted and not work. There are several different network devices as follows.

1. Router

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

2. Wireless Card

This device can connect computers with other computers using Wi-Fi without using cables. Nowadays, many laptops have a wireless card built into them, so there is no need to buy a wireless card separately. Unlike laptops, computer users must purchase a wireless card separately to connect to Wi-Fi.

3. LAN Card

LAN cards can also connect one computer to another. The difference is that LAN cards must connect computers using cables. The LAN card will change the data flow from parallel form to serial form, then the data will be sent 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 coverage wide. The bridge has an internal Bridge table that serves to determine which segments should be filtered.

5. HUB

The function of the HUB is to split the server to another network. The HUB will copy data from the source 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 devices. However, if the HUB has transmission interruptions to other networks, it will be hindered.

6. Switch

The way this device works is almost similar to the HUB, but the switch is smarter in dividing the connection signal. Using a switch, the network area can be better and faster to send data. This device can also resolve data collisions.

7. Access Point

The function of this device is to transmit signals from the router. The signal is used to create a WLAN network. Access Point can also make us connect to a LAN network without using a cable. Then from the access point it can be said that it can connect two different networks, namely a wireless network and a LAN network.

8. Repeaters

Repeaters are network devices that can amplify signals and expand the range of wifi signals. Repeaters allow devices to access wifi easily. Repeaters do not need to use cables to minimize cable usage.

9. NIC

Network interface card (NIC) is a card that can connect a computer to a LAN network. Devices can connect to the network using a cable.

10. Connector

Connectors are vital tools for computer devices. If the connector is not installed, the computer cannot run optimally. The connector functions to connect the cable with the network adapter.

Those are the types of network devices that you should know. After reading the entire article, it turns out that network devices are so diverse in type and function. However, the five devices namely routers, wireless cards, LAN cards, bridges, and HUBs have something in common so that they can connect computers to each other so that they can share information and data.

We understand and know the various network devices that must be monitored in the company. Not just one or two, maybe tens or even hundreds of network devices that we have to pay attention to. Imagine, the complexity if a network engineer in a company has to monitor it manually. Of course it will spend a lot of time, energy, and also money. Especially if there are problems, for example in LAN interference.

Therefore, the use of network monitoring tools is highly recommended. In addition to saving time, energy and money but also to avoid human error as well as to avoid human error and achieve effectiveness in work. When choosing a network monitoring tool, we must be careful and don’t forget to adjust it to our needs such as knowing in advance some of the existing network monitoring tools, understanding the advantages and disadvantages of each tool and so on. After that, then we can make the right choice for our company. Then, have you chosen the right network monitoring tool?
