Which is one of the network physical topologies requires to have a termination at both ends?

Terminators are required at both ends of the backbone cable.

What is the most common topology and technology combination in use today?

Star. The star topology is the most common topology in today’s networks, and includes Ethernet, Fast Ethernet, and Gigabit Ethernet. Each node in a star topology connects to a dedicated link where the other end connects to a switch or hub.

What happens to Wi Fi signals when they pass through solid objects like walls?

What happens to Wi – Fi signals when they pass through solid objects like walls? Absorption occurs and the signals attenuate.

Why is termination important on a physical bus topology?

Termination is important in a bus topology because all buses are together by using electrical cable. The cable has to be terminated by a terminating resistor. *The purpose of terminators is that it absorbs signal and prevent them from reflecting back and forth on the cable.

Which network topology is fastest?

Answer. Data can be transferred at fastest speed in star topology.

Which cable is used in bus topology?

Bus topologies use coaxial cable. Bus topology sections are connected with BNC connectors. T connectors are often used to connect the computer to the trunk cable. The T connector can connect the computer to two sections of cable with the bus extending in both directions.

Which topology has highest reliability?

A mesh network is a local network topology in which the infrastructure nodes connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. Of all these, Star Topology is highly reliable one.

Which topology is best for LAN?

Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.

What is the most common topology and technology?

Star topology is by far the most common network topology. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination.

Does WiFi go through walls or around?

In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily. However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals. Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals.

What blocks WiFi signal?

Everything from building materials like steel and concrete to aquariums and electronics can block and disrupt Wi-Fi signals. This is how coverage issues occur in a home.

What is the maximum range of WiFi?

A general rule of thumb in home networking says that Wi-Fi routers operating on the traditional 2.4 GHz band reach up to 150 feet (46 m) indoors and 300 feet (92 m) outdoors. Older 802.11a routers that ran on 5 GHz bands reached approximately one-third of these distances.

Which topology is most fault tolerant and has most redundancy?

A mesh topology has multiple connections, making it the most fault tolerant topology available. Every component of the network is connected directly to every other component. Characteristics of a mesh topology are as follows: A mesh topology provides redundant links across the network.

What are the applications of bus topology?

Bus topology is used for:

  • Small workgroup local area networks (LANs) whose computers are connected using a thinnet cable.
  • Trunk cables connecting hubs or switches of departmental LANs to form a larger LAN.
  • Backboning, by joining switches and routers to form campus-wide networks.

What are the advantages and disadvantages of a physical star topology?

Star Topology: Advantages and Disadvantages

  • What is Star topology?
  • 1) As compared to Bus topology it gives far much better performance, signals don’t necessarily get transmitted to all the workstations.
  • 2) Easy to connect new nodes or devices.
  • 3) Centralized management.
  • 4) Failure of one node or link doesn’t affect the rest of network.
