There are more than 3 billion regular Internet users in the world today, and we are part of that on an uninterrupted daily basis. The Internet is a network with the possibility of public connection of interconnected computer networks, which transmit certain data (data) using the standard Internet protocol (IP).
In other words, the Internet is a network of networks containing millions of small pieces of regional, academic, business and government networks, which in themselves contain various information and services, such as e-mail, contact forms, written conversations, with video and audio, file transfers, data sharing and other documents from around the world.
So the internet is a network of networks, and what we need to be interested in knowing is how these networks are realized and what their components are.
The components of a computer network are:
Hosts Computers laptops, other mobile devices such as smartphones and tablets).
Router (Equipment that enables the exchange of packets on the network through routing protocols).
Suici (Device through which the end components (computers) are connected to the network).
Connections (connection with wire or optical fiber and wireless connection).
Protocols (IP Routing Protocols, TCP, CSMA CD, CSMA CA
Applications (Network Services).
Users (People and cars).
In this article we will explain the function of the Router, one of the most important and complicated components to configure compared to the others. What is a router, how does it work, and what does the router actually enable?
What is a Router?
A router is a network device that forwards or tracks data packets between computers on a network. The router is connected to at least two different networks and is the critical device that keeps the data flow from LAN to WAN and vice versa.
When data packets reach the router through the network the router reads the address information on the packet in order to determine the final destination of the packet in question.
Then, using the information in the routing table or routing rules it follows the packet to the other network from where the packet continues its journey to the final destination. This creates what is called networking or internetwork
A router is a device that forwards data packets across networks. The router is connected to at least two different networks and are critical devices that keep data flowing from LAN to WAN.
When data is sent from one network to another the packets will still pass through the router which also shows the path to the packets. The router does this by checking the destination IP in the header of each packet and referring to the table where the routes are stored, chooses the best way to forward the packets.
The Internet itself is a global network that connects millions of smaller networks so the importance of the router is very great.
Not all routers are the same as each one depends on the work it does and differs from network type to network. You can see any device and not realize it is a router. What defines a router is not the shape, color, size or manufacturer, but the function of routing packets between computers. A cable modem that routes data between you and your ISP can be considered a router.
What is it for?
These devices offer users a range of functions, some even unknown to many people. They represent a huge benefit to people who need to be connected to the internet on a daily basis. But let's see what those functions are:
The main function is to set the settings to connect different devices to networks, especially the Internet.
Creates different types of internal communication in small areas through so-called WAN, LAN and VLAN data networks
It allows computers to come together to form a small computer network.
Uses more than one connection on a single LAN and thanks to this balances the data flow
Get and manage internet connections
Control - the computers to which data can be sent
Adapts to security procedures, requirements of users who want to connect to the Internet network.
It keeps the flow of information steady.
Generates all the transmission that arrives on different devices
Wireless type models can send a wave signal received simultaneously from different devices and devices. They are very short radio waves that need to be at close range.
It encrypts the data chain in order to transmit smoothly to its destination.
It allows dual connection through cables.
Automatically update direction charts.
Manage data that needs to be transferred from one network to another.
Maintains the security system to allow only those who know a security code and password to register.
Allows you to connect printers via cables or wirelessly. As long as the printing device has some sort of WiFi or bluetooth connection.
Components of a router
These devices are produced in different models; however, its structure and technological architecture is very similar in almost all. They contain microprocessors and microcircuits that help in fast connection to networks
Inside
Each router contains a small CPU, which is a processor that manages all the settings and operations it receives from different locations. The CPU executes various information parameters. This processor is responsible for executing every action and executes instructions from every computer.
Also manages and controls the connection of various devices that are connected. Router power varies by model, so fluctuations can sometimes be noticed if your model is different. There is also RAM, which is responsible for storing data and information instantly.
This memory, though with a limited capacity, is essential as one of the features of a router because they store various direction tables, switching interface and a strong space for the internal operation of the device.
The RAM of a router is similar to that of a computer. So when it goes off it goes back to restoring all the stored information. Another component is the so-called flash memory; It has the function of storing images of the operating system, but is also subject to user requirements.
