In computer networks, a hub is a basic networking device that connects multiple devices in a local area network (LAN). It's often considered a layer 1 (physical layer) device because it operates at the lowest level of the OSI (Open Systems Interconnection) model.
A hub receives data packets from one device connected to it and then broadcasts the packets out to all other devices connected to the hub. It doesn't perform any processing or filtering of the data; it simply repeats the incoming data to all connected devices. This broadcasting method is known as "collision domain" networking, where all devices share the same communication channel.
There are primarily two types of hubs:
-
**Passive Hub**: A passive hub simply amplifies and rebroadcasts the signals it receives without any form of signal regeneration or data processing. It doesn't require any power source and is simply a physical connector for network devices.
-
**Active Hub (or Powered Hub)**: An active hub, on the other hand, requires power and has the ability to regenerate signals. It typically includes additional features like signal regeneration and sometimes includes basic error detection.
Hubs have largely been replaced by more advanced networking devices like switches, which offer improved performance and efficiency by selectively forwarding data packets only to the intended destination device rather than broadcasting to all devices on the network. However, hubs are still occasionally used in very simple network setups or for specific purposes where their characteristics are advantageous.
What else can I help you with?
Is it true that Most computer networks consist of many computers and are usually connected by a networking device such as a hub switch or access point?
Yes, most computer networks consist of many computers that are usually connected by a networking device such as a hub, switch or access point. This type of a network is called a LAN.
What is difference between hub and switch in computer?
a hub is a central point in a network through which all the wires pass, a switch connects more than 2 LAN networks
What will a router do on a network that a hub will not?
In the shortest way to answer: a router takes the information, locates the computer the information is going to specifically, and sends it directly to that particular computer. A hub does the same, but it is more used for Local Area Networks (LAN). *Switches also fall under this category* If internet is desired with a hub or switch, one must take a server (or another computer) and have it communicate to the internet as well as the hub.

What developments has contributed most of the digital revolution?
social networks . or The internet computer networks
What is the difference between computer to hub and computer to computer?
a hub is a central unit.. through which all the wires (termed as transmission medium) pass in a network.. so a computer to hub means the wires are passed through a hub.. whereas computer to computer can mean the computers are directly connected (home LAN) or via hub
What is Gate in computer networks?
There are NO GATES in computer networks... So, ask next question...
Why Computer networks were developed?
Networks were developed as a communication method between computers at remote sites
