An Ethernet hub is a piece of hardware that connects multiple computers

An Ethernet hub is a piece of hardware that connects multiple computers or devices in order to form a network. An Ethernet hub is outdated and has been replaced by a network switch. There are still some special cases where a hub is advantageous to a switch, although none of the reasons to use a hub instead of a switch pertain to a typical network.

An Ethernet hub usually uses the RJ-45 connector on an Ethernet CAT5 cable, although they can also use other legacy (old) connectors. You don't need to worry about specifics because the typical network cable is a CAT5 with an RJ-45 connector. Simply plug one end of the Ethernet cable into the Ethernet port of your computer and the other end of the cable into the Ethernet port of the hub.

An
hub typically has 4 or 5 Ethernet ports. But you can also find Ethernet hubs with 6, 8, or 16 Ethernet ports. You can also connect an Ethernet hub to other hubs, routers, and switches.

A hub is a relatively simple device. A hub receives a signal from a computer on the network and re-broadcasts that signal to all other computers and components attached to the hub. Because all signals sent to the router are rebroadcast to all ports on the router you have the potential for a data collision. This is where a computer is trying to send an outgoing signal during an incoming signal.

A hub is able to detect data collisions on the network and then broadcast a jam signal to all ports on the network. Due to these data collisions the number of hubs attached to one another is limited. For a 10 megabit a second network speed you can attach up to 4 hubs to each other and only 2 hubs can be connected for a 100 megabit a second network speed.

In addition to detecting collisions some hubs are able to troubleshoot network problems. These hubs can detect if a particular port has excessive collisions or jabbering. Advanced hubs are able to disconnect these bad ports from the rest of the hub.

The choices today for Wide Area Network (WAN) design are wide and varied. No pun intended. Relying on the same old legacy options is no longer necessary with the maturation of Business Ethernet interconnectivity. Your voice/data transmission deserves better.

Too often businesses looking to upgrade an existing voice/data network infrastructure... or install a new network for whatever reason... tend to gloss over the advantages a Business Ethernet backbone may present. This may be due to a simple lack of understanding, or perhaps a rush to judgment relying on "what you know" for the final decision.

This is unfortunate as Business Ethernet today presents potential benefits over legacy systems such as TDM (e.g. DS3 bandwidth) and SONET (e.g. OC3 circuits) when the right conditions are present. Upon closer examination these improvements are marked and include the most obvious one. That being a significant cost savings in most cases.

The Internet really changed the way people live their lives. Businesses use the Internet each and every day to communicate and make transactions with other businesses or customers. When the Internet first came out, people had to use a dial-up connection, which is very slow by today's standards. DSL and Cable connections allowed people to surf the web faster than ever before, but there are other options out there, such as Ethernet Internet Access.

This article will discuss whether or not Ethernet Internet is better than DSL or Cable. The truth is that DSL or Cable Internet connections are good enough for a regular home or small business which will have only one to five users using the Internet at one time. However, DSL or Cable is not good for businesses that are going to have many people on the Internet at one time.

Businesses rely on productivity in order to get things done fast and make money more efficiently and having an unreliable internet connection will only cause frustration and a loss in revenues due to the slowness, downtime or time outs; there is a whole list of issues which come into play with DSL and Cable. DSL or Cable Internet connections simply do not met the demands of the growing business and busy business world. Ethernet internet is the new type of internet connection and pretty soon every business will need a faster connection to download all the files they need to share and transfer.

Large or small businesses may have well over 10+ people on the Internet at one time, which is when finding an Ethernet Service Provider becomes very important. Most DSL and Cable internet connections cannot keep up with 10 or more users on the Internet at one time. Ethernet Internet Access was originally used for datacenters and carriers to connect to each other and has now become one of the newest forms of internet connections offered to businesses today.
