Router (computing)
device that connects computer networks
A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet.
Routers perform the traffic directing functions on the Internet. A router is connected to two or more data lines from different IP networks. When a data packet arrives on a line, the router reads the network address in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. A data packet is forwarded from one router to another through an internetwork until it reaches its destination node.
The most familiar type of IP routers are home and small office routers that forward IP packets between the home computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks to powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.
Routers can be built from standard computer parts but are mostly specialized purpose-built computers (embedded systems). Early routers used software-based forwarding, running on a CPU. More sophisticated devices use application-specific integrated circuits (ASICs) to increase performance or add advanced filtering and firewall functionality.
“Router (computing)” enters the record as device that connects computer networks. Crown Archives preserves that source wording while asking what Router, computing and device can confirm, complicate or overturn.
Why this record matters
“Router (computing)” is worth following because a concise public description often conceals a longer documentary argument. Here, Router, computing and device provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q5318. The Library of Congress control number is sh99004539. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
