When you buy a new computer, the first thing you’ll probably try to do is connect to the Internet. To do this, you establish a connection to your router, which receives the data from the Internet and then forwards it to the computer.
A protocol is a set of rules or algorithms which define the way how two entities can communicate across the network and there exists a different protocol defined at each layer of the OSI model. A few such protocols are TCP, IP, UDP, ARP, DHCP, FTP, and so on.
Port: A port can be referred to as a logical channel through which data can be sent/received to an application. Any host may have multiple applications running, and each of these applications is identified using the port number on which they are running.
WLANs. This is a group of colocated devices that use radio transmission instead of wired connections.
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.
Devices attached to a computer network use IP addresses that are resolved into hostnames through a domain name system server to communicate with each other over the 男同网 internet and on other computer networks.
A signal-to-noise ratio compares the strength of a desired signal with any undesired signals created by background noise. See complete definition What is the OSI model? The 7 layers of OSI explained The OSI model (Open Systems Interconnection model) is a multilayered reference model that shows how computer systems and ... See complete definition
You can find detailed information on the IP protocol and its important role in computer networks in our article “What is the Net Protocol ?”.
FTP: Protocolo por transferência por arquivos qual permite este envio e recebimento do arquivos entre dispositivos.
Ring network. Network devices are connected to two other devices on either side through a coaxial cable or an RJ-45 cable.
There are usually multiple network protocols that each perform a specific subtask and are hierarchically organized into layers.
