Weaving networks in our favor
There are many innovators who, not finding solutions to a proposal, resort to a walk through nature as a creative mechanism, finding in it the answers to their questions. Thus we see masterful architectural, railway, fluvial and even technological creations that intersect to form much more complex and functional structures, such as the Nazca roads.
And this intertwining of threads, channels, and connections, only respond to a principle that has changed the application of its concept according to how humanity has advanced. We are referring to Networking, a concept that refers to establishing relationships, weaving personal, professional, business and even technological networks in favor of a service, a person or a company.
If we analyze this term and how it was used over the years, we will find that since 1560 it was already applied in the ancient world. It was first used in large networks and other times in the interconnection of companies, giving rise to strategic alliances.
Later, it was applied to configure the largest of the railway networks worldwide. And so it was used for broadcasting, sales, marketing. Today, this term continues to be strongly applied in the world of Information and Communication Technologies.
We can see that Networking is applied in the connections between technological networks which range from the simplest, like PANs, to the most complex ones, like WANs that interconnect entire cities and countries. And we achieve all of this based on the survival principles from that spider that wove the web in its favor.
Networking: a computer network
Today the principle of the cobweb continues to be used in technological fields and receives the term Networking, which is synonymous with working in a network. In short, connecting computers, servers and telecommunications structures with sharp wires to offer services efficiently.
In the case of computers, Networking consists of establishing a network of computers that are connected by cables, electromagnetic signals or any other method of transport in order to communicate with each other in a “network” simultaneously and immediately to share data, or resources such as optical drives and printers, or to enjoy services such as the internet, chat and e-mail, among others.
The same happens with landlines or cell phones. We are in charge of the largest of networks that interconnect telephone exchanges, nodes and repeater antennas to offer data traffic, mostly through the radioelectric spectrum to offer cellular telephone service.
Working in network
As we have already revealed, the world of technology is based on everyday processes that go unnoticed by our eyes. This is how Networking is based on the process of human communication; where there is a sender who wishes to transmit a message encoded in a language to a receiver with the purpose of obtaining not only the informational transmission, but also seeking a response.
Thus, the main function of Networking, consists of sharing data packets, which are transmitted through electromagnetic or electrical impulses, using special coding for this. In other words, all the components of the network handle the same language, the same codes and protocols for their correct understanding between computers.
Types of Computer Networks
As we have already explained, computer networks are built with the purpose of sharing data and facilitating collaborative work between one system and another or, between one computer and another. Thus we are going to find, like the types of cobwebs, different computer network architectures according to their function, dimensions and geographic scope.
- Personal Network or Personal Area Networks also known as (PAN) or work network in a personal area. We could define it as the interconnectivity between four or five computers in the same office.
- LAN Networks, its name comes from the Local Area Network nomenclature. These are characterized by being smaller and limited in extension, an example of them are the computers in a cyber cafe, a building or a laboratory.
- MAN Networks or Metropolitan Area Networks They are generally medium-sized networks such as those used in the interconnection of large libraries or companies that connect branches geographically distant from each other.
- WAN networks or Wide Area networks We are talking about great coverage networks, and big technological scope. An example of this, is the internet.
- Global Networks or Global Area Networks These covers vast geographies like the orb itself.
- VPN o Virtual Private Networks These are those whose data transmission is through “tunneling”, that is, virtual software that changes your IP address and location. Today it is widely used by managers and high authorities.
Now, in the everyday world we are going to see how these networks coexist or, in the case of telecommunications, how they are integrated until they form an entire technological ecosystem.
LAN Networks or Local Area Networks
This Network is characterized by being made up of equipment such as computers, peripherals that share a physical or wireless communication line, or connected to a server within a different geographical area. This type of network includes cables, switches, routers, and other components that allow users to connect with each other and with peripherals such as printers, scanners, and other components.
A specific case may be the network connection of a business, there you will find computers connected to the cash registers, and these in return with the administrative offices and the warehouse.
How many computers can be connected in a LAN network can go from three computers to hundreds of users if we talk about the headquarters of a bank, for example.
It is important to take into account that these networks are connected to each other in the form of layers to achieve much more robust structures and with greater reach.
MAN Networks or Metropolitan Area Networks
It is a network characterized by having a bandwidth that allows it to reach high speeds in data transmission among thousands of users connected efficiently and satisfactorily within a geographic area.
MAN has the capacity for the integration of multiple services through the transmission of data, voice and videos; using transmission media such as fiber optics and twisted pair, also granted as MAN LOOP and the use of copper pairs as the large connection terminals between venues.
We could affirm that MANs are an extension of the Local Area Networks (LAN) covering larger geographical areas and reaching a regional coverage, or being more ambitious, even national.
MANs are high availability networks or, in other words, it is an indicator that measures working time without failures. To do this, MANs have automatic failure recovery mechanisms. In the case of networks that use copper pairs, a Bonding EFM is used that allows the flow connection in multiple cables.
Another of the characteristics of this _Metropolitan Work Network_ is its high reliability referred to the error rate produced while the network is in operation. This rate being conceived by the number of erroneous bits that can be transmitted through the network, either by optical fiber, the percentage of which is lower than that found in the copper pair cable.
We can also mention that MANs are high security networks for both fiber optics and copper cables, a fact that prevents them from accessing the network, reading it or changing the signal without physically interrupting the link. These interferences or possible unauthorized insertions into the network automatically cause the link to fall temporarily.
How does a WAN network work?
We are talking about a large-scale network characterized by connecting entire networks using other transmission and address protocols. In transmission protocols, it uses the first three layers (1 to 3) according to the OSI reference model. Extending the protocol would be: it works in physical layer 1, linking in layer 2 and in network layer 3.
These networks are also characterized by a uniform addressing scheme in sending data, guaranteeing their efficiency in relation to the number of connected networks.
As we have seen previously, these networks connect or integrate other networks forming a larger structure. To achieve this interconnection, they use network nodes, such as switches, bridges and routed, to guarantee that the data packets arrive at the correct address using the TCP / IP protocols.
