A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in on one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it gets to its destination node.[1]
The most familiar type of routers are home and small office routers that simply pass data, such as web pages and email, between the home computers and the owner's cable or DSL modem, which connects to the Internet (ISP). However more sophisticated routers range from enterprise routers, which connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.
Routers have many uses, but the most common are to connect multiple computers together to share files and a internet connection.
Other uses include:
firewall
DNS forwarder
Network Access Control
Packet Control
& more
Modern networks used two devices for the data packets within the network will flow easily. The two devices are the routers and switches.
It is used by both routers and hosts
Routers, Switches, Modems, and Hubs, but mostly Routers

To stack routers means to physically stack routers. Some stack a couple of routers on top of each other if they plan to just use them as switches or similar.
The ISL protocol can be used in Cisco routers when configuring the subinterfaces.
They are used to run the internet.

CNC routers are used to design and produce many items from many materials including wood and metal. Examples include musical instruments and furniture.
They are used for computers and laptops for internet, and other things. Wireless N routers are pretty much the same thing as a regular wireless router.
LAN can be connected by routers . A router can be used to connect to LAN's .a LAN to a WAN and LAN to Internet.

Wireless routers can be connected via an ethernet cable in the same way as wired routers. If the second router has a client mode feature then the routers can also be connected wirelessly otherwise the second router will only function as a wireless access point.
Most routers can be used. The most popular used will probbaly be NetGear
