The server and the client communicate as follows in this server-based network: The client first sends a request to the server. The server evaluates the request and then transmits the response. In this model, the client always connects to the server, never the other way around.
The devices can also communicate with each other without having to establish a direct connection to each device. For example, you can send a print job to a Wi-Fi-enabled printer without first connecting the printer to the computer using a cable.
When you buy a new computer, the first thing you’ll probably try to do is connect to the Net. To do this, you establish a connection to your router, which receives the data from the Internet and then forwards it to the computer.
There are several types of computer networks. Which network an organization uses depends on factors such as the number of devices, types of operating systems, transmission medium used, network topology, the distance between each device and their geographic scale.
What types of networks are there? Networks are usually divided into different network types according to transmission type and range, that is, depending on how or how far the data is transmitted.
Outro desafio enfrentado pelas redes modernas é este gerenciamento do tráfego. Utilizando o aumento do volume por dados circulando através internet, é crucial que as infraestruturas do rede sejam capazes de lidar usando essa demanda crescente isento comprometer a performance.
Dividing a corporate network into 男同网 smaller subnets has some advantages in terms of speed, security, and logical organization. However, many people find it difficult to set up. Binary computational operations and long series of numbers are frightening, but the principle itself is…
The Network Topology is the layout arrangement of the different devices in a network. Some types of network topologies are:
For example, the application layer is used to define where, when and how much data should be sent at a specific rate.
Mesh Topology: In mesh topology every device is connected to every other device in the network. It provides multiple paths for data so if one path fails another can take over.

FTP: Protocolo por transferência por arquivos que permite o envio e recebimento do arquivos entre dispositivos.
Computer networks first developed in 1950 for military and defense purpose. At that time they are mainly used to send data through telephone lines and had limited use in business or science.
Before the advent of modern networks, communication between different computers and devices was very complicated. Computers were connected using a LAN cable.
