A network is understood to be the interconnection of a certain number of computers (or networks, in turn) through wired or wireless devices.
Electromagnetic waves, or other physical means, allow them to send and receive information in data packets, share their resources, and act as an organized whole through electrical impulses.
The network has processes for sending and receiving messages and a series of codes and standards that guarantee their understanding by the computers connected to the network (and not by any other).
These communication values are known as protocols, and the most common of them today is TCP / IP.
Building a network allows you to manage internal communication, share program execution or Internet access, and even manage peripherals such as printers, scanners, etc.
This type of swarm systems currently supports many management and information processing processes nowadays, such as telecommunications networks, the Internet, or the various intranet companies or multiple organizations.
The appearance of networks revolutionized understanding computing and opened a new field within this discipline to meet the needs for improvement, security, and operability of computer communication.
Network classify rendering to their proportions:
Local Area Network (in English: “Local Area Network”). They are the minimum networks, like the 1s we can connect in our section.
Metropolitan Area Network (in English: “Metropolitan Area Network”). These are medium-sized networks, ideal for a college site or a multi-story library or business building, even for an urban share.
Wide Area Network (in English: “Wide Area Network”). The most extensive and most far-reaching networks come in, such as global networks or the Internet.
Networks can also classify according to the physical method they use to connect, as follows:
A network links the machines through physical cable systems of twisted pair, coaxial, or fiber optics. It benefits from being faster, not having as much noise, but being less contented and practical.
Unguided Media Networks
Networks establish the connection through discrete and area-wide systems: radio rollers, infrared or microwave signals, satellite systems, and Wi-Fi. They are a little gentler but much more comfortable and practical.
There are three representations of topology or order of a network:
Also called linear, they have a waiter at the head of a successive line of customers, and they have a solitary communication station called a bus or backbone.
Each computer has a direct joining to the waiter, which is in the middle of all. Any communication between clients must first go finished the server.
Also called circular, they connect the clients and the waiter in a circular circuit, although the server maintains its hierarchy over the system.
Modems and routers allow communication to establish. An install a computer network, the following elements are needed:
Devices and machines allow communication, such as network cards, modems, routers, or repeater antennas if they are wireless.
Programs require to manage the hardware communications, as is the Operating System Network (acronym NOS: Network Operating System ), and protocols of communication such as TCP / IP.
Servers and Clients
The servers process the flow of data on it, attending to the other computers’ requests on the web called clients or workstations. These allow users to access information individually, sharing the resources managed by the server.
It refers to the wiring or the electromagnetic waves that, as the case may be, serve as a means of communicating the message.
The main job is to provide participants with a single platform for exchanging data and sharing resources. This task is so vital that many everyday life features and the modern world would be unbelievable without it.
The Main Advantages of Network are:
Information technology defines connecting at least two computer systems, either by a cable or a wireless connection. And also, the most straightforward network a combination of two computers connected by a cable. This type of it calls peer-to-peer it.
There is no hierarchy in this; both participants have equal privileges. Each computer has access to the other device’s data and can share resources such as disk space, applications, or peripheral devices (printers, etc.).
