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 Internet.
It provides a standardized set of protocols for transmitting data across interconnected networks, ensuring efficie
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.
TCP/IP is a conceptual model that suggests the following four functional layers for these communication links:
Bus Topology: In bus topology all devices are connected to a single central cable called a bus. Data is sent along this cable and all devices share the same connection. Simple and cheap to set up but if the main cable fails the whole network goes down.
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.
From different types of networks and their components to protocols and security measures, a solid grasp of these concepts is foundational for anyone working in or with technology. As technology evolves, so too will the complexity and capabilities of computer networks, making continuous learning and adaptation crucial.
A importância do networking está principalmente nas diversas possibilidades que uma óptima gestão da rede do contatos profissionais pode trazer para sua própria carreira.
Computer networks first developed in 1950 for military and 男同网 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.
