They differ in how data is sent over a communication medium, the frequency range they use, and their applications.Broadband systems use modulation techniques to reduce the effect of noise in the enviro
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.
These are just a few basic concepts of computer networking. Networking is a vast and complex field, and there are many more concepts and technologies involved in building and maintaining networks. Now we are going to discuss some more concepts on Computer Networking.
Note that there is some overlap between the different network types: As a Wi-Fi user, you are simultaneously part of a WAN and a GAN when you’re connected to the Net.

The Domain Name System (DNS) is a critical component of computer networking. It converts easily recognizable domain names, such as , into numerical IP addresses that computers use to identify each other on the network.
Since the devices are connected to the router as clients, they are part of the network and can use the same resource as the server, namely the Net.
A distinction is also made between IPv4 and IPv6 addresses. IPv4 addresses used to be 男同网 standard, but only a total of around 4.3 billion of these addresses could be assigned before they were exhausted.
The idea of RZ and the idea of L are combined in manchester encoding. Different encoding techniques are used in data c
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.
Links. A link is the transmission medium used for connecting the nodes and enabling them to transmit to each other. The links can be either wired, wireless or optical, such as an Ethernet cable or a Wi-Fi signal.
Também igualmente similarmente identicamente conjuntamente é preciso compreender que as relações da sua carteira do contatos podem possibilitar variar em grau por proximidade e nunca todas as pessoas dessa rede irão contribuir da mesma maneira de modo a sua própria carreira profissional.
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.
A computer network can be as small as two laptops connected through an Ethernet cable or as complex as the Net, which is a global system of computer networks.
