Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
How many types of repeaters are there?
Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.
Major components of Networking Devices?
The basic computer hardware components that are needed to set up a network are Routers, Repeaters, Hubs, and Switches, Bridges, Network Interface Card and Network Cables. you can find all these devices at cyprus pc. Cyprus-PC is the best online store to buy computers, computer accessories, networking equipment, laptops, desktops, routers, wifi routers, etc. from the top brands at the best prices in Nicosia, Limassol, Larnaca, Paphos and whole of Cyprus.
What are the types of USB generic hubs?
what are some types of generic usb hubs
What can bridge do that hubs and repeaters cannot do?
Bridges send information (data) to the specified destination, whereas hubs and repeaters do not.
Which network topology do nodes act as repeaters?
Star Topology, where Hubs can act as repeaters.
Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.

Do active hubs always act as repeaters in a network?
yes
Which device boosts the signal but does not segment the network?
Repeaters and Hubs
What is the maximum number of active hubs or repeaters that can be linked in a daisy-chain configuration?
10
What devices operate only at the Physical layer of the OSI model?
All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
Do connectivity devices such as hubs and repeaters operate at the Presentation layer of the OSI Model?
No. Only protocols that users can see on their screen are considered Presentation Layer based. Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.
Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
Which layer 1 devices can be used extend the area covered by a single LAN segment?
Repeaters and hubs
Discuss the differences between hubs repeaters bridges and switches?
A repeater amplifies a signal. It will also re-send the signal as a "clean" signal. A hub is a multiport repeater. It will send a signal it receives out, through all of its ports - except the port where it received the signal. Bridges and switches are more intelligent, in that they send data only to the destination - according to the MAC address. Bridges and switches are similar, but switches have more hardware optimization, allowing for fast switching of large volumes of data.
