Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate.

Repeaters are network devices operating at physical layer of the OSI model that amplify or regenerate an incoming signal before retransmitting it. They are incorporated in networks to expand its coverage area. They are also known as signal boosters.

How does a repeater extend the length of a LAN? A signal can only travel so far before it becomes corrupted. A repeater regenerates the original signal; the signal can continue to travel and the LAN length is thus extended.

A network hub is a device that allows multiple computers to communicate with each other over a network. It has several Ethernet ports that are used to connect two or more network devices together. While switches send incoming data to a specific port, hubs broadcast all incoming data to all active ports.

Hubs are classified as Layer 1 devices per the OSI model. To connect a network of personal computers together, they can be joined through a central hub. Directs data in a network. A router is a networking device that connects a local network to other local networks.

Do hubs have an IP address? No. A hub is a basic (dumb device) and has no need for an IP address.

A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.

Hubs are now largely obsolete, having been replaced by network switches except in very old installations or specialized applications. As of 2011, connecting network segments by repeaters or hubs is deprecated by IEEE 802.3.

When a hub receives a packet of data (an Ethernet frame) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. Hubs operate in such a way that all data received through one port is sent to all other ports.

Following are the disadvantages of Hubs: ➨It does not have mechanisms such as collision detection and retransmission of packets. ➨It does not operate in full duplex mode. ➨It can not connect different network architectures such as token ring and ethernet etc.

Hubs are at a disadvantage against switches in networking because hubs are unable to differentiate between the devices on the network. If one computer is trying to reach another on a hub-based network, the computer will send the message to every other computer on the network, consuming bandwidth for each transfer.

You can’t make a hub secure. A hub, by definition, is always going to send the traffic everywhere. If you really need to protect traffic and a hub or dynamically configured switch or router is in the network, you can instead just use an encrypted VPN to secure your data over an unsecured link.

A hub is a ‘dumb’ device: if it receives a message, it sends it to every computer on the network. This means that hub-based networks are not very secure – everyone can listen in to communications.

A switch is more intelligent than a hub. As a hub, a switch is the connection point for the computers (and other devices) in a network. However, a switch is more efficient at passing along traffic. It records the addresses of the computers connected to it in a table.

With the introduction of switching hubs as a replacement for repeating hubs, network performance was enhanced by breaking up one collision domain into several collision domains. However, is it necessary for modern Ethernet networks to only incorporate switches? The answer is no.

For this reason, hubs have been predominantly replaced by switches, since they are more intelligent devices that have the ability to learn the MAC address of every device connected to it and can send unicast data, instead of broadcasting potentially sensitive information to every device connected to the hub.

Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need. Hub works in Physical Layer. Switch works in Data Link Layer.

A hub is basic, offering simple data transmission capabilities to MAC addresses over Layer-1. A switch is complex, offering security, efficiency, intelligent function, and capability to transmit to specific in-network, MAC addresses over Layer-2 and Layer-3.

Absolutely negligible. A Gigabit ethernet switch will be faster than most internet speeds. Avoid older switches that only support 10-100Mbps. Technically, yes, any extra cable length adds to latency, and any extra switch adds to latency and might reduce throughput.

Would an Ethernet hub reduce my network speeds? If you are the only one (or 2–3 devices) using it and the hub works at the same speed of your NIC, the hub will not reduce your speed.

Make sure you select a switch with enough Gigabit (10/100/1000 Mbps) Ethernet ports for the devices you want to connect to your network. If you think you’ll add more devices in the future, choose a switch that will give your network room to grow.

Network switches do not increase an incoming internet connection/signal strength. Network switches do not increase an incoming internet connection/signal strength. Network switches provide a more efficent connection to said signal for multiple devices such as computers, cameras, printers, thin-clients, etc.

While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks.

You do not need a router. If you simply want a direct connection between your computer and the cable modem you can connect then directly. The simplest is a switch which will allow you to plug the cable modem into it and have multiple outputs for other wired computers (again Ethernet cable to other computers).

A network switch can be used in place of a router but is not recommended. Internet Service Providers typically only provide one public IP address resulting in only one device being able to access the Internet when a switch is used instead of a router, as well as presenting major security concerns.

In various types of network environments (MAN/ WAN), the router works faster compares to Switch. In a LAN environment, a switch is faster than Router. Switches work with MAC addresses as it operates within the confines of a single network. Routers can work within both wired and wireless network situations.

Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. These networks may be in a single location or across multiple locations. When building a small business network, you will need one or more routers.

Cutting a clean and smooth edge on a narrow piece of wood can be tricky, but a router can produce a nicely finished edge every time. Routers are used to make even and level cuts on both straight and curved edges, and can replicate those cuts on multiple pieces of wood.

Unmanaged and layer 2 network switches do not have an IP address, whereas managed switches and layer 3 switches do. A network switch with an IP address is required for Telnet which allows remote access to the switch. The IP address of a switch can be found via the router or an IP scanner.
