Network
For specific purposes, if something is connected together, it is called network. Networks can be of various types, such as telephone networks, television networks, computer networks and even interpersonal networks。
Similarly, the computer network is a setup that connects two or more devices to share a range of services and information in the form of e-mail and news, databases, documents, websites, audio and video, telephones, and videoconferencing。
The agreement is only a set of defined rules, which must be followed for every connection on the network to communicate and share information between them. In order to facilitate end-to-end communications, many agreements work together to form a package or stack of protocols。
Network terminology may create confusion, especially for those who have recently come into contact with computer networks. The following are some basic terms and definitions that can help you to understand the basics of the network:
Network: a collection of interconnective equipment that can communicate with each other, such as computers, printers and servers。
Node: any equipment connected to the network, such as a computer, printer or router。
Agreements: a set of rules and standards to define how equipment on a network communicates with each other。
Ip address: the only digital identifier assigned to each device on the network to identify and communicate with other equipment。
Routers: network devices that connect multiple networks and transmit data packages between them。
Switches: network equipment to connect to and relay data packages between networks。
Firewall: security equipment or software to monitor and control traffic into and out of the network in accordance with a predefined set of security rules。
Dns (domain name system): translating domain names (e. G. Www. Example. Com) into an ip address system that allows equipment to be located and connected to websites and other network resources。
Lan (local area network): a network connecting equipment within a limited geographical area, such as a household, office or building。
Wan (wide area network): a network of equipment connected to larger geographical areas (e. G., multiple offices in different cities or countries)。
Dhcp (dynamic host configuration protocol): automatically assign ip addresses and network configuration protocols to devices on the network。
Tcp/ip (transfer control protocol/internet protocol): a set of protocols for communication via the internet and other networks。
These are only basic web terms, but understanding them is essential to laying a solid foundation in the computer network。
Some basic agreements are:
Network reference models were developed to allow products from different manufacturers to interact on the network. The web-based reference model provides a blueprint detailing the criteria by which protocol communications should be conducted。
The most widely accepted reference models are the open system interconnection (osi) model and the ministry of defence (dod, also known as tcp/ip)。
The internet is a common term that describes multiple networks connected together. The internet is the largest and most famous internet。
