A computer network is a gaggle of interconnected nodes or computing devices that exchange facts and means with one another. A network relationship involving these units could be set up utilizing cable or wireless media.
A network which mixes many MANs and LANs is called Wide Spot Network; a WAN network handles extensive geographical area commonly masking several towns, locations, nations, or maybe continents.
Company service provider networks. They're network providers that lease network ability and functionality to shoppers. Companies ordinarily include telecommunication providers, knowledge carriers, World wide web services suppliers and cable tv companies.
Network protocols that use aggressive retransmissions to compensate for packet reduction have a tendency to help keep devices inside of a point out of network congestion even after the Preliminary load is lowered into a stage that could not Ordinarily induce network congestion.
Any particular piece of equipment will frequently include several constructing blocks and so could accomplish several features.
Overlay networks have also been proposed as a way to enhance Net routing, for instance through top quality of company guarantees achieve higher-high quality streaming media. Earlier proposals including IntServ, DiffServ, and IP multicast have not observed vast acceptance mostly because they require modification of all routers within the network.[citation required] Conversely, an overlay network is often incrementally deployed on stop-hosts jogging the overlay protocol software, without the need computer network of cooperation from Web company suppliers.
Extranet: An extranet is analogous on the intranet but with connections to certain exterior networks. It is generally accustomed to share resources with companions, prospects, or remote staff members.
Cloud networks. It is a type of WAN, but its infrastructure is sent by a cloud-dependent service, for instance Amazon Web Expert services. Cloud networks are an ordinary technique for modern networks.

计算机网络除了可以按照右方的覆盖范围分类之外计算机网络应用可按照不同节点之间的功能关系分为：
Exactly what is the dark World wide web?Understand the dark Website. It has a high profile but would make up a minuscule portion of the Internet.
Star network: A central node server is linked to multiple other nodes. This is quicker given that data doesn’t really have to journey via Each individual node.
In case you don’t choose appropriate protection safety measures like file encryption, firewalls then your information might be in danger.
The most striking illustration of an overlay network is the online world by itself. The online world alone was at first constructed as an overlay on the telephone network.[sixty] Even currently, each Web node can communicate with just about every other by means of an fundamental mesh of sub-networks of wildly various topologies and technologies.
