The networks have greatly facilitated the work in offices and homes. Many people simply hire their Internet connection + Router, install it and start surfing the net with total freedom. However, many times we do not know the basic concepts and operation of computer networks.
After a time, one realizes that it has miscalculated and has enough wide side for the number of devices you want to work. Or you are surfing with a wireless network at a slow speed, when structured cable could surf the Internet much faster.
To understand some of the connection problems that sometimes we can find, you need to understand some things about computer networks. What happens when installing a computer network? What are the components of computer networks and how do they work? We explain it to you in a simple way.
Components of a computer network: how they work
A network is a set of computers, networked computers or devices that can exchange information and resources from one to another, such as printers, hard drives, etc. Wifi networks that we all know are computer networks, but without cables. They can be twisted pair cable, UTP, fiber optic, wireless communication or other means.
In any case, the components that we find so that a computer network can be created are the following:
Issuer: creates a signal or request from the computer.
Encoder: encoding the signal to be transmitted through the cable. It can be a network card, which comes embedded in computers, and deals with converting the sent request into a format (bits) that can be transmitted. For this, a protocol, such as TCP / IP, is used. In addition the network cards have a MAC address (Media Access Control), which allows them to be clearly identified, so that information reaches the right receiver.
Online: in wired networks will be the means of transmission network cables, while wireless radio waves or infrared. They conduct the received information to the address of the device that has been indicated through the interface.
Decoder: the device that is to share information or resources also has its own system for converting electrical signals into data that can process the computer. They are the network adapters, or PCI. These come integrated in the motherboard and can work at different speeds.
Receiver: is the device that receives the signal that has transmitted the issuer converted into actionable data by the computer.
While these are the basics, many networks do not directly connect computers to each other, but are connected to a router, switch or bridge network , which are those that receive and send signals to their respective receptors.
Computer networks have not always been optimally installed for the purposes the user wants. If so, it should make a study of the needs and call a computer technician who takes charge of the review.
Do you have a computer network installed in your home or office?
