IT People Blog – Understanding the ins and outs of computer networks for ordinary people may not be easy. Included in understanding the meaning of computer networks PAN, LAN, CAN, MAN, WAN are quite specific. Even though this network is quite useful to ensure all important data can be connected to each other. So that general knowledge about computer networks should be owned by computer users.
For initial information, computer networks are generally a combination of software systems and hardware systems on a computer. So that this network can be created thanks to the combination of the two devices that help generate data connections or exchange information as needed. In practice, there are several types of computer networks including PAN networks, LAN networks, CAN networks, MAN networks, and WAN networks.
This article will discuss in detail about PAN, LAN, CAN, MAN and WAN networks. Starting from understanding, to the advantages and disadvantages of the network. So that computer users can see and decide which network is the most appropriate to implement.
Definition of PAN Network
The first computer network that we will discuss further together is the PAN network. This network is an abbreviation of the Personnel Area Network. In terms of terminology, a PAN network is a network that connects two devices that are close together. So that this can help two devices that are within a few meters to connect and share data
The advantages of using this PAN network are quite a lot. The first is to help connect the two adjacent devices to each other. The next advantage, this network allows the exchange of information from one device to another.
Although it has several advantages above, of course this network also has disadvantages that need to be considered. The main drawback of this network is the connection that can only be done within a limited distance, even only a few meters, as previously informed. So it can only be used for a limited connection to one room only.
An example of the implementation of this PAN network, we find connections between laptop devices and smartphones using Bluetooth. Where this connection is only limited to a short distance.
Understanding LAN Network
Next there is a LAN network stands for Local Area Network. LAN network is a network that connects one area with a fairly high data transfer rate. The advantage of this network is that it allows fast data exchange between devices in the area. In addition, there is no need for a telecommunications network to help support the network.
But on the other hand, it’s a shame that this LAN network can only connect certain areas. So it cannot be used on a wider geographic scale. As an example of the implementation of this LAN network, for example in the same office area, or in a school building
Understanding CAN Network
The next computer network that is no less important is the CAN network. The definition of the CAN network itself is a network that is only available in one area of an educational institution. Understandably, the CAN network stands for Campus Area Network, so it can only be implemented around certain campus buildings.
This network is a combination of several LAN networks that are specifically used only by educational institutions. The advantages of this computer network system are of course similar to the advantages of the LAN network above before. It’s just that the area that is the focus of the network is the education building area in the form of a campus.
Unfortunately, using the CAN network, it can only be accessed while in the campus area. So that if it is outside the area of the educational institution, the data access requirement automatically cannot be carried out. For example, if you want to access student course data.
Definition of MAN Network
Then the next network that is no less interesting to know is the MAN network, which stands for Metropolitan Area Network. From these abbreviations, it is quite clear that this MAN network is a network that works to help transfer data between buildings in a city at high speed.
Automatically with this MAN network, it can help connect several LAN networks in a city.
In accordance with the area cover, generally this MAN network only works for an area of 5 to 50 square kilometers. Where this is a general area for urban areas. Of course this network will not be accessible outside the area.
The example of a MAN network in general that is widely used is the local government office network. Which can link information between agencies in one city. Another example is the interbank network that can be accessed between banks at the head office and banks at branch offices in one city. With this kind of network, it is possible to exchange important data and information between offices.
Definition of WAN Network
Furthermore, there is also a WAN network, which stands for Wide Area Network. A WAN network is a computer network that can be accessed on a wider scale. For example between cities or even between countries. So this network requires routers and public communication channels to support it.
The advantage of using a WAN network is of course access to data and information that is easily obtained anywhere. With a very large network scale, this can be done easily. In addition, this network helps connect various LAN networks and MAN networks to exchange important information.
However, when using a WAN network, the drawback is that it requires large operational costs. In addition, with a wide coverage area, automatically a more complicated security system is needed to avoid unwanted risks. Because this kind of network is vulnerable to hackers and data theft.
The easiest example of a WAN network to find is the internet network. Where everyone can access the network. In addition, another example of a WAN network is a network between international companies that have branches in various countries. So that between one office and another can exchange information easily.
That’s a little information about the understanding of computer networks PAN, LAN, CAN, MAN, WAN that needs to be understood by computer users today. So with the general knowledge above, computer owners can find out which network is needed. By using the right network on the computer, of course the work can run more effectively and optimally. And the exchange of data via the network can be done properly.
