Question: What’s the difference between a router, network switch, and an ethernet hub?
What do they do exactly? Which ones would I need if I simply want to divide an internet connection equally between two computers?

I already have a router and it’s giving both my computers an internet connection. But Whenever both computers are in use, one of them tends to hog all the speed leaving the other one with extremely low speeds or completely disconnected. Which device would i need?

Look in the source for more information on what the difference is.

The problem you are experiencing isn’t really down to the hardware you are using, it’s down the router giving priority for bandwidth. To help with this, some manufacturers have an in-built bandwidth limiting program you can access by going through your router settings.

If your router doesn’t have this feature you can download a program which you can find on the web on the other computer to limit the amount of bandwidth it uses.

A wireless router is a machine that connects to the source of your Network or Internet connection and transmits it to other devices wirelessly.

A Network Adapter is something that can be plugged into a laptop or other device to allow it to connect to the router since it didn’t have the ability before.

A modem, in simple terms, is like Network Adapter that can connect to the Network or interact with it but provides a basis for it, often with a wire.

Part One of two videos showing how to create a Site to Site VPN tunnel between Cisco Routers.

Google Tech Talks April, 24 2008 ABSTRACT Why is route calculation done at both layers 2 and 3 of networking? Is one better? Do we need both? This talk explains the historical accident by which bridging was conceived and the properties that make it attractive, as well as dangerous, today. The talk discusses new work being done in IETF known as TRILL (TRansparent Interconnection of Lots of Links), which combines the advantages of bridges (layer 2 forwarding devices) and routers (layer 3 forwarding devices). Although the basic idea is fairly simple, certain properties of bridges, such as their ability to create partitioned VLANs on a layer 2 cloud, make the design challenging. Speaker: Radia Perlman Dr. Radia Perlman is a Fellow at Sun Microsystems, working on network and security protocols. She invented many of the basic algorithms that make today’s network infrastructure robust and scalable. Her current research interests include assured delete, making large networks robust against Byzantine failures, and replacing bridges/switch with technology which is upwardly compatible, but more robust, flexible, and scalable. She is author of “Interconnections: Bridges, Routers, Switches, and Internetworking Protocols”, and coauthor of “Network Security: Private Communication in a Public World”, which are widely used both as textbooks in universities and for engineers to learn the field. She holds over 90 patents, a PhD in computer science from MIT, and an honorary doctorate from …
