The OSI model: How do network protocols work?To understand the nuances of network protocols, it's imperative to know about the Open Systems Interconnection (OSI) model first. Considered the primary architectural model for internet working communications, the majority of networking protocols used today...
While we’ve only covered some of the most common ones here, dozens of protocols work in unison to facilitate communication and data exchange across the global internet as well as private networks. Each plays a specific role in powering different aspects of networking: establishing connectivity, tr...
The Internet Protocol (IP) is a set of rules for sending and receivingdataover theInternet.Computersgather data into collections of electrons calledpackets, with IP identifiers attached to each one.Network routersensure that packets are routed to the right place. All Internet connecteddevices, froml...
Telnet is a set of rules used to connect one computer to another computer. The process of this connection is called asremote login. The computer who request connection is called local computer, who accept the connection is called remote computer. If you type commands in local computer remote l...

Once they solidify those answers, then they can select which type of network and connectivity to deploy. Editor's note:This article was updated to include additional information and improve the reader experience. Deanna Darah is site editor for TechTarget's Networking site. She began editing and...
Compare the common types of network devices. 3. Gateway A gateway is anetwork nodethat connects discrete networks or systems that use different protocols, enabling data to flow between the networks. Gateways use multiple protocols and translate an incoming packet's information and protocol to make ...
of 06 Local Area Network (LAN) rawpixel / Pixabay People associate computer networking with LANs more than any other type of network connection. A local network consists of a collection of devices located in close proximity to each other (such as in a house or an office building) connected ...
HTTPS proxies work just like their HTTP counterpart, with the difference that they can use theSecure Socket Layer(SSL) and/orTransport Layer Security(TLS) protocols to perform end-to-end encryption and decryption between the client and the server, without either of them being able to detect the...
