Depends on how many switches each router takes. You need a router to connect all the other routers, and then enough switches to make 81. For example, you can use 6 16 port routers to connect the computers and 1 8 port router to connect those routers together

What are routers used for?

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.


How many computers are there in all?

that's hard to tell because there are always computers being made and sold and there are always computers being thrown out and scrapped. If you go to speedtest. Net it shows you how many computers that are on the internet that exact moment

Do most wireless routers allow you to connect wireless and wired computers to the same network?

Many Wireless routers and switches have few inbuilt switching ports capable of connecting Wired computers to Wireless Computers on the same network to connect wired Computers also alongwith. (Not necessarily every every wireless router will be having switching ports)


How can you connect 4 routers to 6 switches?

A network can function fairly easily with just one router, the router is used to access the internet and in small home it is also the network switch that connects all the home computers together. It is not necessary to connect 4 routers together on the same network because each router will try to assign an ip-adress to each of the computers on the network resulting in many conflicts. If you did want to do this type of network (depending on your circumstances, i know of schools that use routers as small network switches for each room) then I suggest that you disable DHCP and all server attributes of the routers. Then you use a star network configuration for the 4 routers that are connected elsewhere, use long Ethernet cables to link the routers to a network switch each; from there have the 2 remaining network switches in the same room and have them in a redundancy layout. Connect the 4 router and switch pairs to the redundancy pair. This network is very inefficient and very costly but you have the capability to join a small office to a larger office four times over in the same network. It is not recommended that you do this.


Why do you use router?

to connect multiple computers to the same internet connection, and to network the computers together Routers allow multiple computers to share a single internet connection. This helps save a lot of money. Apart from this, routers also add a safety element to a local network. The individual IP addresses of the computers on the local network are never exposed to the internet. Instead only the external IP address of the router is publicly known. Moreover, many routers come with additional features like firewalls, filters and other security enhancing abilities.

Do you need a good Ethernet router to power a good computer?

All routers perform the same action. They allow you to hook up multipule computers, and also giving your network security. Many people debate between which routers work better, and which have more reliability, i would recommend researching online and find some reviews. Routers do not "power" computers. There is a technology called power over ethernet but it's generally used for network attached storage devices or routers rather than "computers."
